Q: What is the common thickness range for Q235 steel coils?
A: The common thickness range for hot-rolled Q235 steel coils is 1.2–20 mm. Thicker or thinner specifications can be customized for special needs.
Q: What are the common widths for Q235 steel coils?
A: Common widths are 1000 mm, 1250 mm, and 1500 mm. Some manufacturers can produce 2000 mm wide coils.
Q: How is the weight of Q235 steel coils calculated?
A: Theoretical weight formula: Weight (kg) = Thickness (mm) × Width (m) × Length (m) × 7.85 (steel density, g/cm³).
Q: How is the corrosion resistance of Q235 steel coils?
A: Corrosion resistance is relatively poor. It is a type of carbon steel and is prone to rusting in humid environments. Anti-corrosion treatments such as painting and galvanizing are necessary.
Q: Can Q235 steel coils be welded?
A: It has excellent welding performance and can be used in various welding methods such as electric arc welding, gas welding, and resistance welding, without the need for special welding processes.
