The steel structure processing process meets the most detailed standards

Steel structure processing is an important step in creating a pre-engineered steel house with a sturdy structure. What steps does the process of creating a steel structure include? Refer to BMB Steel's article to get useful information.

1. Steel structure processing process

The structural steel fabrication process is complex, requiring attention to detail to ensure the safety and quality of the final product. Below are the detailed steps in the process from material selection to the finishing stage:

1.1 Selection of raw materials

The material used to create steel structures is steel. Steel materials are used to design foundations and house frames. Besides, raw materials are also located in the connection part such as bolts, or iron. These materials need to be carefully selected to see if they are sturdy and of good quality to ensure the steel frame has good strength and a guaranteed structural connection.

1.2 Check materials

Imported materials must be carefully checked for the source of material supply. Must be confirmed to ensure material safety as well as ensure construction technical requirements. Check the lock or system of columns and beams. Along with that is the tightening force of structural bolts or even anchor bolts.

1.3 CNC and hydraulic cutting

After importing raw materials and carefully checking the quality, the construction unit will conduct CNC and hydraulic cutting. This step will create curves for the metal material. Any curve as shown in the drawing is possible. Can be cut in 3D, not just 2D.

1.4 Manual welding

Manual welding is the 4th step in the steel structure processing process. The pieces of material that have been cut, shaped, and created will be manually welded to bond them together. Manual welding will be done by construction workers, directly by human hands.

1.5 Automatic welding

Some shortcomings of manual welding that cannot be resolved will be resolved by automatic welding. Automatic welding will be performed by machines, robots, or CNC automatic welding trucks. Joining patterns are 100% resolved for solid bonding.

1.6 Hydraulic cutting machine

Use a hydraulic cutting machine to cut excess details in the whole that have been welded together. The operating principle of this cutting machine is to apply fluid pressure, i.e. hydraulically, to cut metal quickly and with high technology.

1.7 Straighten the structure

During the process of welding steel structures, the heat from the machinery will cause some parts of the material to become warped and distorted. This is when it is necessary to use a straightening machine to straighten the structure. This is very important so that the steel structure frame can ensure quality in the steel structure processing process.

1.8 Grinding processing

For steel structures to be accurate in area and perimeter as well as aesthetic and smooth, grinding is required. Includes methods:

• Grinding flat
• Round the outside
• Internal circular grinding: Helps in machining tapered holes, cylindrical holes, and shaped holes
• Shaping grinding: Grinding and machining positions and surfaces with straight birth lines
• Centerless grinding: Suitable for structural details without step

1.9 Non-destructive welding seam inspection

The weld seam must be checked after performing the welding methods to see if it meets standards. Between two material components that need to be inspected after being welded together, they will be checked visually, or it can be ultrasonic or magnetic testing.

1.10 Clean and prepare the surface

This stage is very important for the surface of the structure to be clean, ensuring there is no dust or interference in any position. It plays a role in maintaining the longevity of the structure and retaining the paint layer better. Can be cleaned using hydraulic methods.

1.11 Paint finish

The finished paint layer will be painted in two layers. First is a coating for the metal surface to prevent environmental impacts that cause rust. Next comes the exterior paint to create an aesthetically pleasing structural appearance. The paint layer is very important to protect steel structures for a long time and be stable.

1.12 Complete and pack, transport to the construction site

After completing the above steps, the steel structure will be inspected again overall. The final step in the steel structure processing process is to transport construction materials to the construction site to proceed with erection as shown in the drawings.

The process of processing steel structures must be carried out in the right stages and standards to bring high-quality and aesthetic pre-engineered steel buildings.
