Damp Proof Insulated Steel Structure Underground Storage Warehouse Building

We are a comprehensive steel structure factory based in Shandong. We have independent production workshops for steel workshops, storage tanks and modular container houses. All production procedures are finished in our own factory, providing one-stop design, production and export service without middlemen markup.

Sure. Our engineering team designs drawings according to local wind load, snow load and seismic standards. We support international standards like EN, ASTM and Australian standards instead of only GB standard, using AutoCAD, PKPM, 3D3S and MTS to provide complete construction and foundation drawings.

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.

We accept two mainstream payment methods for bulk orders. T/T requires 30% deposit for production, and the 70% balance can be paid before shipment or against BL copy. Irrevocable sight L/C is available for long-term partners. Western Union and PayPal are acceptable for small sample orders.

We own full production lines without outsourcing processing, so we can strictly control production costs. Our core principle is lower price under equal quality and better quality under equal price. We optimize structural design to save steel consumption and cut clients' total project cost.
