Frequently Asked Questions

Common questions about ordering steel structure buildings from ZhongSai

What steel grade do you use?+

We primarily use Q235B and Q355B (equivalent to ASTM A36 and A572 Grade 50) for primary framing. For special projects requiring higher strength or corrosion resistance, we can specify ASTM A992, weathering steel, or galvanized members. All materials come with mill test certificates (MTC EN 10204 3.1).

What is included in the building package?+

Our complete package includes: primary steel frame (columns, rafters, bracing), secondary framing (purlins, girts, eave struts), roof and wall cladding, doors and windows, all bolts, fasteners, sealants, and flashing. We even include 5% extra bolts as spares. You will not need to source anything separately.

Can you design for our local wind and snow loads?+

Absolutely. Our engineering team designs according to your local building codes and site-specific loads. We regularly design for: high wind zones (hurricane/typhoon areas up to 150mph), heavy snow regions (up to 150kg/m2 snow load), seismic zones (up to magnitude 8), and extreme temperature ranges.

Do you provide installation services?+

We provide comprehensive installation support through three levels: (1) Detailed erection drawings with numbered components, (2) 24/7 remote technical support via WhatsApp video, and (3) On-site engineer dispatch for complex or large projects. Our engineers can supervise installation, train local crews, and ensure quality.
