FAQ

Q

How to perform daily maintenance and inspection of steel structures during use?


A
Regularly check components for rust, deformation, loose bolts, etc., promptly repair damaged areas, keep the drainage system unobstructed, and regularly repaint with anti-corrosion paint.
Q

What preparatory work needs to be done before installing a steel structure?


A
Component quality and dimensional deviations need to be checked, connecting parts cleaned, installation equipment and tools prepared, and installation plans and emergency response plans formulated.
Q

What are the main differences between light steel structures and heavy steel structures?


A
Lightweight steel structures use thinner steel sections (such as cold-formed steel) and are mostly used for buildings with smaller loads; heavy steel structures use thicker steel sections and are suitable for projects with large loads and spans.
Q

How are the column spacing and span of steel structure factory buildings usually determined?


A
Needs to be comprehensively determined considering production process requirements, equipment layout, material specifications, and economics. Common column spacing is 6-12 meters, and the span is 15-30 meters.
Q

What changes occur in steel structures under high-temperature environments, and how can these be addressed?


A
High temperatures reduce steel strength. Fire protection measures can include applying fire-retardant coatings, encasing with fireproof panels, and installing water spray systems.
Q

What are the common structural forms of large-span steel structures?


A
Common forms include truss structures, space frame structures, grid shell structures, cable-stayed structures, and membrane structures.
