In this day and age, steel structure has become the most common structural form. The application of steel structure engineering technology has become widespread across the globe. This is due to the benefits that steel structure offers. Steel is like a skeleton of the structure. The way Skelton in our body gives proper to our body, steel helps in giving important structure to the buildings. It is therefore important to judge the quality of steel to construct a robust, high-performing, durable, and long-lasting structure.
Steel Grade
Check the manufacturer’s plan of action, and materials and look at the grade of the steel. Ensure whether it is as per the order. In general, steel bars of grades Fe 415 and Fe 500 are used in the structure. These steel grades with other structural steel grades are utilized in frames of bridges, structures, and buildings.
Type & specifications
Make sure that the types, specifications, and performance of steel products adhere to the existing national product standards and design requirements.
Check Surface
The steel surface should be free of cracks, delamination, slag inclusions, and 1mm missing edges. You can also have a look at the manufacturer’s test certificate. This will allow you to see the actual properties.
Unwanted debris and rust
Checking unwanted debris and rust is another important part of judging the quality of steel structures. Not a very good amount of foreign materials is acceptable. It is necessary to check splits or deformation. A little rust can be ok.
The Pre-assembly Components
Use a hole-trimming device in order for checking the connection between high-strength and ordinary bolts. If you choose to use a hole-operator with a diameter smaller than 1.0mm, then the pass rate should be not less than 85%. Avoid using fast cutting electric welding.
Raw Materials
Keep a record of specifications, types and performance of materials in the main components of the drawing as per current national standards. Also, examine the specifications, varieties, and performance of high-strength bolts and connecting pairs, rivets, ordinary bolts, connecting pairs, anchor bolts, nuts, beams, frames, and so on. To conclude, a steel structure is an excellent option in place of concrete buildings. It is easy to build, long-lasting, and less expensive. Before getting started with the construction check all the points above to ensure you can get what you expect from the structure.
