8 years fabricating for Baosteel, CSCEC and China Railway — that standard is now available for your project.
One coordinated manufacturing package: primary steel structure, purlins, and the full cladding system — from a single factory.
Welded H-sections, columns, and crane beams. Plate up to 60 mm, single members up to 36 m.
Long-span roof structures on a dedicated space-frame line. Spans up to 75 m.
Workshops, warehouses, and livestock facilities — structure, purlins, and cladding as one package.
We have manufactured for Baosteel Construction and Jinggong Steel — two of China's tier-1 steel structure contractors — continuously for more than eight years. Their inspectors are on our floor. Their standard is our baseline.
The same team also serves China State Construction and China Railway engineering bureaus. AAA corporate credit rating.
Design in-house: Tekla, PKPM, AutoCAD, SAP2000. Concept drawings in 3–5 days, led by a Grade-1 registered structural engineer.
The full route has twelve stations — these are the six your inspector will care about. Photographed on our own floor, not stock images.
Everything we claim on this page can be checked — by your inspector, on our floor, before the goods ship.
Appoint SGS, BV, TÜV, or your own inspector. We schedule around them and open the workshop — welding, testing, coating, and loading.
Every bundle ships with a CE-verified product details list. Every member carries its erection number. Your site team can match steel to drawings on day one.
A 15-engineer team — design led by a Grade-1 registered structural engineer — working in Tekla, PKPM, and SAP2000. Send your drawings, or a sketch, and get a professional response, not a form quote.
Q345B / Q235B sourced from two of China's major mills, with mill test certificates supplied for every batch. Seven QC checkpoints from plate to port.

Whether this is your first import from China or your fiftieth — the process is four steps, no mystery.
Drawings, a sketch, or just the building dimensions — enough for our engineers to start asking the right questions.
We review the structure, flag what needs clarifying, and confirm the scope before any number is quoted.
A detailed quotation with a delivery proposal — and a price you can hold for 3 months.
Fabrication, QC, and export packing. Third-party inspection welcome before the goods leave the factory.
Send your drawings, a sketch, or just the size of the building you have in mind. I'll come back with questions an engineer would ask — then a price you can hold for 3 months.
