Including checking the installation size and hole spacing of the drawings, releasing the nodes in a 1:1 large sample, checking the dimensions of each part, and making templates and sample rods for cutting, bending, milling, planing, hole making, etc.

Draw Lines

Including checking and checking the material, marking the cutting, milling, planing, hole-making and other processing positions on the material, punching holes, marking the part number, etc. Material determination should pay attention to the following issues:

  • According to the ingredient list and the template, the sets are cut to save materials as much as possible.
  • It should be conducive to cutting and ensure the quality of parts.
  • When the process has regulations, the materials should be taken according to the regulations.

Cutting and Blanking

including oxygen cutting (gas cutting), plasma cutting and other high-temperature heat source methods and mechanical methods such as machine cutting, die blanking and sawing.


including mechanical straightening and flame straightening of steel straightening machines.

Edge And End Processing

methods include shovel edge, planing edge, milling edge, carbon arc gouging, semi-automatic and automatic gas cutting machine, groove machining, etc.


Symmetrical three-axis rounding machine, asymmetric three-axis rounding machine and four-axis rounding machine can be selected for processing.

Simmering And Bending

According to different specifications and materials, machines such as steel rounding machines, pipe bending machines, and bending presses can be used for processing. When using hot forming, be sure to control the temperature to meet the specified requirements.

Hole Making

including rivet holes, ordinary connecting bolt holes, high-strength bolt holes, anchor bolt holes, etc. Holes are usually made by drilling, and sometimes punching can also be used when making holes for thin and unimportant gusset plates, backing plates, reinforcing plates, etc. Drilling is usually carried out on a drilling machine. When it is not convenient to use a drilling machine, electric drills, pneumatic drills and magnetic drills can be used.

Steel Structure Assembly

methods include ground sampling method, copy copy assembly method, vertical assembly method, tire mold assembly method, etc.


It is a key step in the processing and production of steel structures. It is necessary to choose a reasonable welding process and method and operate it strictly according to the requirements. Read More

Treatment Of The Friction Surface

sandblasting, shot peening, pickling, grinding and other methods can be used, and the construction shall be carried out in strict accordance with the design requirements and relevant regulations.


The construction shall be carried out in strict accordance with the design requirements and relevant regulations.

Steel Structure Design

According to the development in recent years, steel structure buildings have gradually replaced traditional reinforced concrete structures, and steel structures have many advantages in the actual application process that traditional buildings cannot be more beautiful, such as fast construction time, low cost, and easy installation. , the pollution is small, and the cost can be controlled. Therefore, we rarely see unfinished projects in steel structures.

Pre Engineered Metal Building

Pre Engineered metal building, its components, including roof, wall, and frame are pre-manufactured inside the factory and then sent to your construction site by shipping container, the building needs to be assembled on your construction site, that’s why it is named Pre-Engineered Building.






3D Metal Building Design

The design of the metal buildings is mainly divided into two parts: architectural design and structural design. The architectural design is mainly based on the design principles of applicability, safety, economy, and beauty, and introduces the design concept of green building, which requires comprehensive consideration of all factors affecting the design.
