FAQs

1. Can I use a smaller-sized steel square tube for my project to reduce costs?

Reducing the cost of steel structure buildings requires starting from multiple aspects, including design, materials, production, construction, etc. By comprehensively considering various factors, costs can be effectively reduced, and the competitiveness and market share of steel structure buildings can be improved.

2. What are the advantages of using hot finished steel pipes over cold finished ones?

The advantages of hot processing include: the risk of component fracture during the processing is low, and intermediate annealing is not required. If the process is correct, it can ensure grain refinement and is not prone to producing anisotropic textures in terms of performance. The disadvantages are that it is difficult to maintain the hot processing temperature, and the surface size and roughness after hot processing are not as precise and smooth as cold processing. There is oxide skin and decarburization may also occur, and the structure and performance of the workpiece after hot processing are not as uniform as cold processing.

3. Are there any limitations on the shapes that can be fabricated using square metal box sections?

Box girder refers to a beam with a rectangular or square cross-section, commonly used in engineering fields such as bridges and building structures. According to different classification standards, the cross-section of box beams can be divided into the following types:

1. Rectangular box girder: The cross-section is rectangular, suitable for bridges and building structures with smaller spans.

2. Square box girder: The cross-section is square, suitable for structures that need to withstand vertical and horizontal loads.

3. Trapezoidal box girder: The cross-section is trapezoidal, which can be adjusted to a certain extent. Improve the bearing capacity and stiffness of the beam.

4. Circular box girder: The cross-section is circular, which can improve the motion stability and load-bearing capacity of the structure.

4. Can square metal box sections be painted or coated for added protection?

Yes

5. What type of maintenance is required for steel square tube structures in coastal areas with high humidity?

The square section needs to be hot-dip galvanized or hot-dip galvanized aluminum magnesium treatment.
