Import H Beam, C/Z Purlin, Sandwich Board, Construction — Buy in Bulk from Supplier in China

The offering consists of light structural steel H‑beam, C/Z purlin and coloured sandwich board products manufactured by Baotou Duowei New-type Construction Sheet Co., Ltd. in China. The supplier lists a z‑type purlin pattern of 100 mm × 250 mm and a c‑type purlin pattern of 80 mm × 300 mm, both formed from the same steel base. These components are intended for use in roofing and decking structures where a lightweight yet load‑bearing profile is required.

Sandwich boards are produced with a range of core materials including expanded polystyrene (EPS), polyurethane (PU) and mineral wool such as rock wool or glass wool, providing thermal insulation and fire‑resistance options. The steel skin is typically a carbon‑steel grade equivalent to Q235 and is usually hot‑dip galvanised to improve corrosion resistance. Standard panel thickness falls between 0.8 mm and 2.0 mm, with width and length tolerances of ±1 mm to ±2 mm respectively. Typical packaging bundles the panels on wooden pallets, each bundle extending up to 12 m in length for efficient handling.

Primary users are construction contractors, building material distributors and developers of industrial warehouses or cold‑storage facilities.

Trade terms such as minimum order quantity, incoterms and payment method are not disclosed in the listing and must be confirmed directly with the supplier. Shipping is normally arranged from ports in northern China, with freight forwarding and customs clearance handled by the buyer or a nominated agent.
