Steel Anchoring

Steel Anchoring

TEKMETSAN supplies a detailed Anchor Bolt Plan with every metal building system. These plans show the building dimensions, the precise locations for anchor bolt placement, and the total number of foundation anchor bolts required in the structure. 

Anchor bolts are not just the connection elements between the steel and concrete surfaces but they are one of the most important element in a steel structure. Anchor bolts are responsible for the transfer of loads between the steel and concrete member.

Depending on when the anchors are installed, anchors used by Tekmetsan are classified into two categories;

1. Cast-in Anchors

These are the type of anchor bolts that are installed in place before pouring the concrete and are efficient in handling forces of high magnitude. Bolts are firmly held in place while the concrete is poured to maintain proper alignment and position.

The size and location of the anchors can be determined from construction drawings.

 In the below figure, you can see some examples of cast-in anchors.

2. Adhesive Anchors ( Chemical Anchors)
Adhesive anchors are anchor bolts that are placed in a pre-drilled hole, which contains an adhesive that dries and bonds to the anchor rod thread as well as the concrete.
Adhesive anchors, also known as epoxy anchors or chemical anchors, are capable of reaching high bond-stress values in relatively fast cure times.
Adhesive anchors are fully threaded rods that can be supplied in many different grades and finishes and can be cut to any length required for a given application.
How to install epoxy anchors?

Good installation is critical to performance. Here is the 5-step for the installation. 

1. DRILLING: Drill correct hole size and depth on concrete/brick/stone/masonry.

2. HOLE CLEANING: Blow out dust and clean the hole with brush, then blow out remaining dust.

3. INJECTING: Inject mixed adhesive from the bottom of the hole.

4. INSERTING: Insert and rotate stud/bolt/anchor/rebar/threaded rods into the hole.

5. HARDENING AND CURING: Time table refer to TDS. Don’t touch until full curing.

• All structural columns on a building must be anchored by at least four anchor bolts

• The placement of all actor bolts on the structure must adhere to the approved Engineered Foundation Plan

• All anchor rods shall be placed with their longitudinal axis at a 90-degree angle to the surface of the foundation

• A template (preferably steel) must be used to insure exact placement of anchor bolts in concrete.

Steel Detailing

Steel Detailing

Structural steel detailing has evolved as a critical engineering approach in the construction industry, requiring great precision. Even a minor mistake might result in a significant loss of time and money.

Steel detailing is an important and necessary step in construction of residential and commercial structures, factories and institutes. 

Steel detailing provides a communication that collaborates key stakeholders such as architects, contractors, fabricators, and others who are involved in the project at any level.

Creating comprehensive steelwork drawings serve as a guide for the structural steel detailing process.

What is the scope of steel detailing works at Tekmetsan?

Structural steel detailing entails the development of comprehensive drawings for our fabrication similar as plans, estimates, and other necessary reports and activities. There are two sorts of drawings we used in this process: shop drawings and erection drawings.

The erection drawings specify the placement coordination of each steel component within the structure and detailed dimensioned plans. It is the construction site steel erector who refers these drawings in the steel detailing process, in order to know how and where to build with the fabricated steel pieces. 

Included in the erection drawings are dimensional plans to identify the steel members, in addition to all work required on the site including bolting and anchoring.

Shop drawings on the other hand are more detailed. Each steel component, such as columns, beams, braces and purlins are meticulously detailed in the shop drawings. This describes how steel fabricators should make each component.

Component dimensions and sizes, bolting, welding, material specifications, and other details required for each component’s fabrication are all included in the shop drawings.

With its decades of experience, Tekmetsan is responsible for the design, strength, and integrity of steel constructions. For the fabrication and erection of steel members, structural steel detailing aids in the creation of detailed structural drawings, design plans, and a range of construction documents.

Steel detailing is a vital link in the project’s communication chain and to avoid any kind of misunderstandings during or after the construction process, providing a universal communication ground between the architect, general contractor, client and Tekmetsan.

With steel detailing, comprehensive shop drawings may include for each piece:
• Size
• Material description
• Required dimensions
• Surface preparation
• Bolting
• Welding
• Painting requirements
• Manufacturing conventions
• Special fabricating guidelines.
Traditionally steel detailing was carried out manually by pencils, rulers, templates of circles, triangles, drafters, drafting machines, etc. Later, these primitive methodologies were substituted by Computer Aided Designing (CAD), a specific software used only for designing in 2D and 3D which are nowadays integrated within a BIM interface.

Steel Helicopter Hangars

Steel Helicopter Hangars

Helicopters require the exceptional protection of pre-engineered steel hangars. No other building system guards helicopters and other aircraft as well as a durable steel prefab hangar.

Why Steel is the Only Sensible Choice for Helicopter Hangars?

To create the lift needed to fly, helicopters must be extremely lightweight.  The endless vibration of a helicopter in flight takes its toll on these machines. Consequently, helicopters require diligent maintenance— and heavy-duty protection.

Pre-engineered metal hangar buildings offer the best protection at the best possible price.

Tekmetsan metal prefab hangars are durable, waterproof structures for all types of rotorcraft, gliders, jets, and other aircraft. Designed to withstand mother nature at her worst, TEKMETSAN buildings promise built-in resistance to earthquake, fire, lightning, snow and wind damage.

Metal Hangar Buildings Benefits

TEKMETSAN helicopter hangars offer the benefits chopper owners appreciate most:

• Unobstructed space— TEKMETSAN hangars promise clear span, column-free interiors up to 45 meters wide.

• Towering heights— Choose hangars up to 12 meters at the eave height on a standard TEKMETSAN hangar design.  Even taller structures are available with additional engineering.  Taller hangars allow ample space for a variety of aircraft— and leave room for two-story offices, kitchen space, or pilot and personnel quarters.  Unlike arch shape buildings, TEKMETSAN hangars supply maximum usable space.

• Limitless lengths— Pre-engineered steel buildings and hangars can achieve any length required.

• Watertight protection— TEKMETSAN’s fasteners with built-in sealing washers, die-formed ridge caps, sealed eave closures, and formed-based trim keep the hangar dry in all types of weather.  

• Bolt-together system— No welding, cutting, drilling, or painting is necessary with a TEKMETSAN hangar.  Our pre-engineered system reduces the erection time significantly.  

• Bird-proof ceilings— Unlike truss-type buildings, TEKMETSAN’s rafter-and-beam portal frame buildings offer no place for birds to rest or nest overhead, fouling your chopper, equipment, or the crew!

 

Building a Hangar that Suits Your Specific Needs

Customize your helicopter hangar with stairs, overhead cranes, mezzanines, vents, gutters, or skylights and wall lights
whatever you need to make the building ideal for your helicopter or other aircraft.

Choose from an array of exterior panel options.  Finish the exterior with stone or brick accents for an upscale look.

Conclusion

Keep your chopper or aircraft safe from the elements with an affordable, long-lasting, low maintenance TEKMETSAN prefab hangar. 

When building a hangar for your aircraft, you can trust TEKMETSAN Steel Building Systems.  TEKMETSAN ships competitively priced steel helicopter hangars and aviation support structures all over the World.

steel and earthquake

Steel and Earthquake

There is a mistaken belief among some people that steel buildings do not do well in earthquakes. The truth is quite the opposite. In fact, steel buildings have a distinct edge over concrete in earthquakes. The reason, however, is counter-intuitive, and worth understanding.

We tend to think that the heavier and more rigid an object is, the stronger it is. This assumption is especially common regarding buildings, because our day-to-day experience validates it. If you’ve ever been in a wooden house during high wind, and heard the timbers creaking and groaning ominously, you might have wished the structure was concrete. We assume that the weight of concrete would help hold the house down, and the unbending nature of concrete would resist the swaying under the wind impact. That makes sense if the impacts are on the scale of a truck hitting a wall, or even a hurricane. 

However, an earthquake is different than other loads. It isn’t a surface force threatening to sweep the house off its foundation. The earth itself moves, moving the foundation of the building. It’s more like a strong bucking bronco, trying to shake the house off its back.  

Steel construction is lighter in weight than concrete, without compromising strength. It has less mass – and therefore less force – to damage itself under seismic shaking. It requires less earthquake resistance to be built into the superstructure and into the foundation, potentially lowering construction costs, too.

Moreover, steel makes a more resilient structure because it is a more ductile material, allowing it to bend considerably before breaking. It will respond better in an earthquake than a more brittle structure. In smaller seismic events, a steel building is more likely to snap back than it is to crack. Should the maximum seismic event for which the building is designed occur, there may be severe deformities, but it won’t undergo progressive collapse. 

Tekmetsan Steel Structures will meet or even exceed all local building codes including seismic codes. Let us know the location of your building and we will provide the ideal steel design for your building.

5 Factors to choose your steel supplier

5 Factors to choose your steel supplier

Should You Choose a Concrete, Timber or Steel Structure?

Should You Choose a Concrete, Timber or Stell Structure?

Concrete, timber and steel are three of the most common building materials used today. The material you should choose for your structure depends on many factors, such as the type of building, your budget, and the capabilities of your worksite. Concrete, timber and steel each comes with their own advantages and challenges, so which one should you choose?

Concrete

Concrete has been used since ancient times, and today it’s often chosen for its durability, versatility, thermal mass, and low maintenance.
For high-rise buildings or long-span bridges, structural concrete provides maximum strength, durability, and the ability to withstand a high level of tensile stress.
Concrete is environmentally friendly because it is made from readily available materials – sand and limestone – and it’s also fire and weather resistant.
Choosing a concrete structure also provides a wealth of aesthetic possibilities.
Concrete can be easily incorporated with other materials to create colours or patterns, and it can be moulded into any number of shapes, because it starts in liquid form.
Compared to steel, concrete requires less skill to erect.
However, because of the many steps involved in erecting reinforced concrete, the final strength can sometimes be affected if there has been poor workmanship.
Another risk with concrete is that shrinkage can cause cracks or loss of strength.

Timber

Timber is cost effective, naturally durable and has a high structural efficiency as carried load per unit.
If it’s sourced from sustainably managed forests, it can be a more environmentally friendly choice than steel or other building materials.
Timber is ideal for use internally as it maintains a pleasant level of humidity inside a dwelling, and it absorbs sound – preventing echo and noise inside.
The natural beauty and warmth of wood creates an aesthetically pleasing atmosphere, as each tree has its own colours, smells and patterns, depending on how it was sliced.
Timber is lightweight, easy to work with, and adaptable to offsite manufacturing, so it is often used in low-rise residential structures.
However, timber can deteriorate over time due to decay, mould, bacteria, insects, weather or fire.
This means a timber structure may require more maintenance than concrete or steel.

Steel

Steel has a high strength to weight ratio, making it a better structural material for low and high-rise buildings, long-span bridges, or buildings on soft ground. Steel is often used in major construction to speed up development, reduce onsite risks, and minimise waste. Computer modelling can be used to ensure components are manufactured correctly the first time, minimising rework. Buildings with steel structures are often lighter and have smaller foundations because steel is structurally efficient. Steel structures can be erected quickly and with fewer workers needed onsite, reducing labour costs. Compared to concrete, erecting a steel structure creates less noise and dust on a worksite and surrounding areas. Steel is fire resistant, termite free, and a large portion of steel can be recycled.

Value Engineering Structures

Value Engineering Structures

More than one reasonable, safe and acceptable solution can often be applied to a particular design. Value engineering asks: “Which acceptable solution is most economical?” and “Does an entirely different and better approach exist?” To answer both questions effectively, depth and breadth of experience is required.

The performance benefits of steel in relation to strength, stiffness, lightness, prefabrication and quality are facilitated by a range of principles for value engineering at each stage of a project and across a number of stakeholders, including: 

• lighter is not always better 

• utilise prefabrication and modularisation when appropriate

• implement responsive member and connection detailing

• repetition and standardisation

• design for construction 

• minimise the potential for variations

• design for economy 

• life cycle costing

Vastly experienced Tekmetsan engineering department provides value engineering for all projects even without it is requested by the client. We believe having over 70% repetitive or referred clients is the outcome of this standard procedure. 

 

Some value engineering activities that we are constantly checking are;

• Suggesting changes to parts to give better nest utilisation and avoid material wastage

• Designing parts for manufacture that suit existing capabilities

• Taking down material gauges but adding design features to retain structural integrity

• Making assemblies easier to assemble

• Adding features which will provide fast and safe erection

• Substituting materials based on the availability on the market and price levels.

 

Steel Mezzanines

Steel Mezzanines

When it comes to increasing space, it is more economical to building up rather than to expanding outward. Mezzanines are the most common solution for building additional space inwards. A mezzanine is an intermediate floor inside a building, usually with direct access from the inside of the building.

There are a few different types of mezzanine construction, depending on the size and application. To ensure the right solution for your needs, you need to understand the variety of structural options and decking types available.

Cold rolled refers to the method of forming sheet metal into a c-channel to use as the framework of the mezzanine floor.
Cold-rolled material is much lighter than structural steel and therefore easier to handle. It can also be pre-galvanized; offering a substantial savings over painted, hot-dipped galvanized mezzanines.
Cold rolled sections are generally used as a primary or secondary beam member rather than column members.

The major disadvantages of cold-rolled mezzanines is the very limited column spacing (usually 3-4 meters max) and the inability to reach the high live loads or heavily concentrated point loads accomplished with hot rolled mezzanine systems.
Structural steel mezzanines are constructed of structural I beams, which connect to tubular columns or I-beam columns to form a primary frame.

The greatest benefit of structural steel is allowing bigger column spacing. Column spacing can increase up to 8 meters without compromising the dead and live loads on the mezzanine floor.
This means more material can be stored in a smaller area ⎯ with more space for manoeuvrability underneath.

Your mezzanine does not depend on the building for support and can be used as a totally freestanding structure or can be combined with your existing equipment.
Our mezzanine floors are individually designed and engineered to suit your specific needs.

Flooring or Decking Type

Since the type of mezzanine decking you choose will be determined by a variety of circumstances, you have a lot of options when it comes to designing your flooring system.
Whether you’re establishing an office and need a deck to support the building’s visual appeal, storing large goods and require a reinforced material to offer adequate support, or anything else, the correct decking will ensure that your floor is perfectly finished.

Tekmetsan, as experts in this field, would be delighted to assist. We’ve got you covered on everything from the suitability of mezzanine decking to which materials look best.

The most durable type of mezzanine decking is concrete. Concrete should be utilised in high-capacity industrial and military applications where the mezzanine is considered permanent since it has a high point load and negligible noise transmission through the deck.
Steel decking comes with a pour stop that allows you to pour up to 15cm of concrete.

In the waste management, mining, and food service industries, steel grating, also known as bar grating or press-locked grating, is a popular alternative.
Air, light, heat, and fluids may all pass through the deck surface thanks to steel grating. It’s powerful, long-lasting, and almost maintenance-free.

Most economical selection for general storage and office applications is the OSB flooring. OSB provides good resistance to foot traffic and can handle random wheel loads up to 150 kg.

Produced from hot-rolled steel, alongside its structural configuration made up of an evenly distributed raised pattern, our chequered plate flooring type is extremely robust and durable as well as anti-slip as standard.

Conclusion

Our mezzanine floors are individually designed and engineered to suit your specific needs.
• Maximise existing floor space into profitable rentable areas
• Increase net rentable areas by utilising full building heights
• Fully engineered and certified
• Metal fabricated stairs and Balustrades

Steel building assembly

Steel building assembly

In our fast-moving world, steel buildings are offering great value to consumers.
Their large span design, versatility, and fast erection make them the ideal choice for the people investing in buildings for workshops, residential buildings, commercial and industrial space and many more other building types.

The versatility is only limited by your imagination during the design process.
The accuracy of the manufacturing of steel buildings makes erecting a steel building quick and safe; therefore, occupancy can be in weeks rather than months.

Much like any construction, careful attention must be given to the below considerations for standing a building.

What are the basic requirements to start erection ?

1. A good packed flat excavated surface is the start for the whole process. A groundwork contractor may help you to 

2. The concrete must be poured correctly with a flat uniform surface. Dips or valleys will cause you problems in the later stage if they are not dealt right after the pouring. 

3. The anchor bolts must be set and squared off to insure fit for the building columns. The blueprints provided by Tekmetsan is your guide in the anchor bolt instalment. We always recommend you to consult a land surveyor whilst placing the anchor bolts.

4. An erection must be performed according to the manufacturer’s assembly requirements. There should not be corrections needed if all phases of this project are complying with the stamped prints supplied. 

5. An accredited building manufacturer should be assigned. The building can only be erected in a safe and timely manner with no delays if the manufacturer supplies good quality and correctly manufactured parts.

How long should erecting a steel building take?

This is a frequently asked question, and the answer is dependent on several factors.

There are certain things that cannot be counted on when an erector gives you a quote to build your steel structure.

• Is the foundation ready and anchor bolts correctly placed?

• Weather forecast- Any rainy or snow days ahead

• All the steel parts are ready on jobsite.

• Any damaged or faulty part?

• Access of the crew and lifting equipment to the jobsite is possible

When an erector is scheduling their works, they have to take into account the equipment and crew required at the job site, how long it should take to complete various stages of erection, and making sure they can get to their next scheduled appointment on time.

When the next job is scheduled and any of the above problems happen, the equipment and crew become idle which will cause a financial burden either to erector, the customer or both. Crews have to wait and reschedule equipment and manpower to return for better weather or new parts. Also delays may affect the schedules of the next job of the erector causing them losing their next job. It is very important to us at Tekmetsan that the erectors have all they need. And also all parts are correct and accounted for. We provide detailed assembly drawings and part drawings to make the job of the erector as easy as possible. The easier and faster the building goes up is a compliment to us and also a value for our customers.

Erection check list

• Foundation: anchor bolts are placed correctly and levelled

• Access to the jobsite for delivery of the materials, equipment and crew

• Clear job site around the foundation so materials can be separated and stacked as needed

• Equipment to unload the truck and manpower to inventory bundles and crates.
