Project Description
A prefabricated metal building is a portal frame of welded Q355B H-beam columns and rafters, shop-fabricated into short, bolt-connected sections that travel in containers and assemble on site without welding. Bay spacing is typically 5–7.5 m and eave height runs 3–9 m, so the same kit can be scaled from a small garage to a warehouse or workshop. Roof and wall cladding is either single-skin corrugated sheet for shelter use or insulated sandwich panel where temperature matters, fixed to galvanized C/Z purlins. The frame sits on a light strip or pad foundation on pre-shipped anchor bolts, and openings for roller doors, personnel doors and windows are framed during fabrication. Design follows GB 50017 with wind and snow per the site code; steel consumption for this building type typically runs about 18–30 kg/m², varying with span, eave height and local loads.
To receive free drawings & a quotation: please provide length × width × eave height plus local wind speed (m/s), snow load (kN/m²) and seismic zone; intended use, required doors and windows, cladding type (single-skin or insulated), and foundation condition on site. Our engineers will design the building to the wind / snow / seismic loads of your local code and return a detailed quotation within 48 hours.
Product Advantage
1. Bolt-together kit that erects quickly with a small crew and no site welding
2. Dimensions and eave height tailored to the use, from garage to warehouse
3. Choice of single-skin sheet or insulated sandwich cladding to match the budget and climate
4. Light strip or pad foundation requirement keeps civil works simple
5. Doors and windows framed in the factory rather than cut on site
6. Manufactured under ISO 9001 with export packing and long-distance shipping experience
Factory Capability
The kit is produced in our own workshop on H-beam welding and C/Z purlin roll-forming lines, with plasma cutting and shop welding per AWS D1.1 / GB 50205. Because the field joints are all bolted, shop fit-up accuracy is checked against the erection drawing, and every part is tagged under our ISO 9001 quality system.
Installation
Each building ships with step-by-step erection drawings, bolt lists and part marks; the kit is designed so a local crew can bolt it together with ordinary tools, and our engineers provide online or video guidance throughout. Anchor bolts are sent ahead so the strip or pad footing can be poured and the first frame stood immediately.
Packing & Loading
Frame members, purlins and cladding panels are bundled and stacked in container order, bolt sets are boxed, and the whole kit is packed to export seaworthy standard into 40'HQ containers. Loading photos are taken before the containers are sealed, and a packing list with shipping marks lets the receiver check off every bundle.
