A: Our products cover three core categories. First, prefabricated steel buildings including factory workshops, warehouses, hangars, bridges and space frames. Second, carbon steel storage tanks with volume from 1m³ to 50000m³, vertical and horizontal styles available. Third, modular housing such as standard container houses, expandable capsule houses and light steel villas.
Q: Can you offer customized design service adapt to local standards?
A: Sure. Our engineering team designs drawings according to local wind load, snow load and seismic standards.

A: Main steel grades are Q235B and Q355B; Q345R pressure vessel plates are used for storage tanks. C/Z galvanized purlins, EPS or rock wool sandwich panels are used for secondary parts. We can adjust material standards to match clients' local building codes, and all raw materials pass third-party inspection before production.
