Quality Assurance of Tekmetsan Steel Structures

Quality Assurance of Tekmetsan Steel Structures

At Tekmetsan, we go above and beyond to provide our customers with the best quality metal building systems we possibly can. 

Metal fabrication requires an eye for detail, and with so many variables coming into play it is crucial that those overseeing your job have the knowledge and experience necessary to deliver a quality product. 

Sloppy and hasty workmanship can negatively affect the appearance, structural integrity and overall lifespan of the steel structure.

In this post, we’ll be shedding some light on the quality assurance procedures and what makes our structural steel stand out from our competitors.

 
The Need for Quality Assurance

Metal fabrication is not a simple process, particularly when it comes to structural steel. You are already aware of the incredible properties of steel which include its strength, longevity, aesthetic appeal and robustness to name just a few. 

But what you may not be aware of is that poor refinement and fabrication can compromise the finished product, leading to vastly reduced strength and longevity.

At Tekmetsan we keep a close eye on the finish, aiming to remove all defects prior to delivery to ensure a great customer experience.

How to Erect a Steel Building

How to Erect a Steel Building

The erection of structural steelwork consists of the assembly of steel components into a frame on site. The components are then lifted and placed into position before they are connected together.

Steel erection essentially consists of four main tasks: 

• Establishing that the foundations are suitable and safe for erection to commence.

• Lifting and placing components into position, generally using cranes but sometimes by jacking. To secure components in place bolted connections will be made, but will not yet be fully tightened. Bracings may similarly not be fully secured.

• Aligning the structure, principally by checking that column bases are lined and level and columns are plumb. Packing in beam-to-column connections may need to be changed to allow column plumb to be adjusted.

• Bolting-up which means completing all the bolted connections to secure and impart rigidity to the frame.

Generally, connection is achieved through bolting but, in some cases, site welding is used. The assembled frame needs to be aligned to within tolerance expectations before final bolting up is completed. 

The completed steel frame may then be handed over to following trades in an acceptable condition. 

Design for construction

The successful construction (including erection) of steel structures safely, quickly and economically starts long before the actual steelwork arrives on site from the fabrication shop. The ‘buildability’ of the structure is influenced significantly by decisions made during the design process long before erection commences.

It is important that designers clearly understand the impact of their decisions. Design for construction is a valid design objective and one that should be considered along with the other usual design objectives in play.

Erection planning

Planning for erection should start at the very beginning of the design process. Such planning should consider the construction sequence, the design factors that affect buildability and site practice in terms of typical erection plant.

 

In the broader design and planning context, there are three planning factors that affect the buildability of steel structures:

1. Practical erection sequence: the location of both temporary and permanent bracing systems or other means of maintaining structural equilibrium are crucial here

2. Simplicity of assembly: simply assembled connections are the main factor here

3. Logical trade sequences: which will affect the development of the master contract programme as the pre-tender plan metamorphoses into the construction plan.

Conclusion

Tekmetsan supports its clients during the erection works and offers free consultation and installation guideline to assist the clients.

Nuts and Bolts of Metal Buildings

Nuts and Bolts of Metal Buildings

Structural bolts are one of the key elements of a steel building system. Their manufacturers and suppliers form an important part of the steel construction supply chain.

Structural bolts play a vital role in steel construction, as the majority of steelwork projects will always have an abundance of bolted connections. For this reason, bolts or fasteners are considered to be one of the key structural elements in a steel frame and vital to a structure’s safety and speed of completion. 

Every building is only as strong as its connections. Structural Fasteners are characterised by strong, heavy-duty materials that facilitate the construction of structures employing steel to steel connections. They are an ideal choice of tool for connecting one metal structure to another.

Structural fasteners come in a variety of types and are used for a wide range of applications. They are widely used in bridge and building construction, to connect metal columns and beams. To qualify as tools employed primarily for “structural” purposes, fasteners need to be made of quenched and tempered steel.

Heavy Hex Bolts

Heavy hex bolts are characterised by a distinct hexagonal head, making them larger and thicker than standard hex bolts. Heavy hex structural bolts are ideal for steel-to-steel structural connections. They are typically very short. The A325 and A490 specifications are not intended for general applications, including anchor bolts. A449 for A325 and A354 grade BD for A490 are a more suitable choice in these applications.

Heavy Hex Nuts

Also known as Finish Nuts, Heavy Hex Nuts are used along with bolts – both for strength and for a thick finished look.

Flat Washers

These are high hardness and low deformation plain washers, punched washers, or flat washers, used as spacers and load distributors.

Bolts and Cap Screws

They include carriage bolts; Grade two, five, and eight plow bolts, and more.

Construction Screws

They are heavy-duty fasteners that include weld studs, concrete anchors, and more.

Threaded Studs

Whether you’re going with an all-thread rod or an all-thread stud, they are perfect for heavy-duty projects including manufacturing equipment, motors, and construction.

As seen above, there is a wide variety of structural fasteners, each suitable for specific applications. When used properly with the right hardware elements, they perform their functions successfully. Insisting on the highest quality when choosing structural fasteners is essential, as they will hold together heavy and crucial structures.

Thus, structural fasteners should be durable, sturdy, rust-proof and corrosion-free, and serve their purpose over a long period of time. Using poor quality structural fasteners not only reduces the strength of the structure but also puts lives at risk.

Conclusion

Tekmetsan provides first-class steel prefab buildings— right down to the nuts, bolts, and screws. 

Steel Structure Connection Types

Steel Structure Connection Types

When it comes to steel construction, steel connection is one of the most crucial design component, in terms of cost as well as integrity of the structure. If connection types and arrangements are not carefully chosen, it can account for up to 20% of total cost of the production.

Most commonly used connections are the bolted connections.  This connection has the advantage of flexibility in assembling parts of the structure as well as dissembling it and which is necessary if there is inspection or some routine maintenance. This type of connections is applicable for members subjected to tension or shear or both tension and shear. 

The advantages of bolted connections are as follows:

• The process of erection of structure can be made faster.

• Skilled labours are not necessary.

• Connections do not involve the noise.

• Less labour requirement

• Immediate use of structure is possible in case of bolted connection.

• The alternative arrangement of structural members is possible if required.

• Lesser working area is required.

Some frequently used connections are

 
• Base plates
• Fixed moment end plate
• Apex Haunch
• Clip Angle
• Gusset
• Splice
• Gable wall
• Bracing

5 Reasons to Use Steel Construction For Your Project

5 Reasons to Use Steel Construction For Your Project

Project management requires a lot of responsibilities. You must ensure that the objectives are met, that the quality is of a high standard, and that the customer is satisfied with the end result. The materials you use for the project have a direct impact on these factors. In this blog, we discuss why you should consider steel construction for your project

1 – COST-EFFECTIVE 

Structural steel is generally the most cost effective framing material. It brings greater value to a project because the initial cost is reasonable and because of the nature of the material, it reduces the cost of the other construction works, such as façade systems, flooring and mechanical equipment.

2 – FAST

Structural steel is fabricate offsite which allows other parts of the construction to take place during the fabrication time such as site preparation and foundation works. Once the structural steel is brought to site, it is super easy and quick to erect, thus speeding up the whole project schedule.

3 – LARGE SPANS

As structural steel is both lightweight and strong, it has the capacity to cover long spans than concrete and timber. It also requires less columns, therefore creating open plan floor space.

4 – HIGH PRODUCTIVITY

Structural steel uses advanced technologies to improve the design and construction stages. Computer-aided manufacturing and BIM (building information modelling) are just some of the systems used. These advanced technologies have been proven to reduce or completely eliminate errors, lower project costs and also improve safety.

5 – QUALITY ASSURANCE

As mentioned previously, because structural steel is fabricated offsite, under controlled conditions, the company producing it can ensure that it is to a high standard. By doing this, it can also reduce the number of costly fixes on the job site.

Steel Structure Galvanizing

Steel Structure Galvanizing

Galvanizing is the process of applying a protective zinc coating to prevent rusting.
The most common method is hot-dip galvanizing, where the steel parts are submerged in a bath of molten zinc.

Hot dip galvanization is a highly-specialized job therefore at Tekmetsan, galvanization works are subcontracted to the specialized subcontractors.

Although it is a more expensive type of coating compared to 2 layer organic paint coating, hot dip galvanization offers the below great advantages;

1. Durability

A galvanized coating is one of the most durable forms of corrosion protection on the market. An average coating thickness of 85 microns, the same thickness as a sheet of A4 paper, can protect a steel framed building for the better part of more than 50 years.

2. Sustainability

The long-term durability provided by galvanizing is achieved at relatively low environmental burden in terms of energy and other globally relevant impacts.

3. Reliability

Galvanizing is a relatively straightforward and closely controlled process. The coating formed is consistent, predictable and simply specified. Hot dip galvanizing is defined by a single standard – EN ISO 1461.

Unlike a paint coating, the metallurgical bond that is formed through galvanizing becomes part of the steel itself and is not merely a chemical or mechanical bond.

Due to the metallurgical bond that is formed when steel is dipped into molten zinc, a galvanized coating offers straightforward, secure protection from the get-go. Hot dip galvanizing requires rust-free, uncontaminated steel for the process to occur. Once the coating is present, it is impossible for it to fail from underneath. Other coatings can adhere to residual contaminants, this can undermine performance, lead to flaking and cause premature failure.

4. Predictability

A galvanized coating offers predictable corrosion protection that weathers in a linear fashion. Coating thicknesses are measurable and offer lifespans that can be easily forecast and relied upon.

Batch hot dip galvanizing is a standardized process which produces a quantifiable coating thickness. The coating is simply specified through European and international standards.

The coating thickness depends upon the gauge of the steel that is galvanized and is produced consistently across the component, both inside and out. This can be measured easily throughout its lifetime, using non-destructive methods.

5. Complete Coverage

There are multiple reasons why hot dip galvanizing outperforms other organic coatings. A crucial factor is the way the process achieves complete coverage of a component, both inside and out.

The dipping of steel into a tank of molten zinc via the hot dip galvanizing process means the zinc can access even the trickiest areas.

A further benefit of hot dip galvanizing is that hollow components are coated on internal surfaces too, meaning that a structure will not corrode from the inside out. In addition, the coating will also build up at vital corners and edges, unlike brushed or sprayed coatings, which traditionally thin out in these areas.

6. Abrasion Resistance

Galvanizing has an abrasion resistance up to ten times better than organic paint coatings. The hot dip process is unique, producing a coating which is bonded metallurgically to the steel.  As a result, galvanized steel has superior resistance to mechanical damage during handling, storage, transport and erection.

Conclusion

Along with paint coatings, Tekmetsan offers hot dip galvanization finish to its steel fabrications. It is essential to know whether products are going to be galvanised right in the beginning of the design phase in order to customise the part design for the hot dip galvanization.
