Frequently Asked Questions (FAQ)

Q1: What steel grades do you use for the main structure?

A1: We primarily use Q355B and Q235B high-strength structural steels. These materials ensure structural stability and conform to international design norms.

Q2: How do you address regional building code differences?

A2: Our engineering team has extensive experience working with various local design standards and code requirements to ensure structural compatibility and safety verification.

Q3: What types of surface treatments are available for steel components?

A3: We offer hot-dip galvanizing and multiple painting processes (such as Alkyd paint and Epoxy Zinc Rich coatings) to secure excellent long-term anti-corrosion protection and minimize maintenance costs.

Q4: Are the structural steel components welded or bolted on-site?

A4: Most prefabricated components are connected using high-strength bolts (Grade 10.9 or 8.8) to allow for fast on-site installation. Critical load points are professionally welded to maximize connection strength.

Q5: What enclosure options are available for the roof and wall systems?

A5: We provide composite panels, 360° locking seam roof systems, locking screw systems, and rockwool maintenance systems that deliver excellent thermal insulation and weatherproofing.

Q6: Do you provide ventilation and access accessories?

A6: Yes, we provide customizable options for powered or unpowered axial flow ventilators, ventilation towers, and sliding, rolling, or fireproof doors and windows.
