China Steel Material Cheap Prefab Structure Warehouse Garage

We manufacture a wide range of steel structures including industrial workshops, logistics warehouses, multi-story steel office buildings, bridge steel structures, pipe trusses and space frames, as well as steel platforms and walkways. These are suitable for industrial, commercial, logistics, and municipal projects. Please share your project requirements and we will recommend the most suitable structural form.

We offer multiple anti-corrosion solutions: 1. Shot blasting (Sa2.5 grade) + primer/intermediate/topcoat paint system; 2. Hot-dip galvanizing (ideal for highly corrosive environments); We can customize the coating system based on the project's climate conditions and design service life (15 years, 25 years, etc.).

Our standard grades are Q235B and Q355B/D. We can also supply high-strength structural steel in Q420 and Q460 grades upon request. All steel materials come with original mill certificates, with full traceability to heat/batch numbers, ensuring compliant material quality.

Primary load-bearing welds comply with Class I or Class II weld standards (GB 50661), inspected via UT (ultrasonic testing) or RT (radiographic testing) non-destructive methods. Full inspection reports are issued. All our welders hold recognized qualification certificates.

For structures with complex joints or export projects, factory pre-assembly is recommended to ensure on-site installation accuracy and efficiency. Upon successful pre-assembly, dimensional acceptance records and complete photographic documentation are provided. Costs are quoted separately based on complexity.
