Standard Size Prefab Metal Structure Buildings / Light Steel Frame Structure Warehouse
Standard Size Prefab Metal Structure Buildings / Light Steel Frame Structure Warehouse. We built six standard size prefab metal structure buildings for our clent that is used for leasing as shops and warehouses. The main steel frame structure of this building is welded H-section steel columns and beams that is connected by high strength bolts. The size of each building is the same. We could design it to be single span, double span, portal frame or truss roof.
Prefab steel frame structure buildings has lots advantages such as light in weight, high in strength, large in span, short in construction period, correspondingly reducing investment cost, convenient to move, non-polluting and environmentally friendly, and can be widely used in factories, warehouses, restaurants, gymnasiums, large markets, leisure resorts.
Qingdao Ruly Steel Engineering Co.,Ltd is a professional steel structure fabrication and construction company for light and heavy steel structure Design, Manufacture & Installation.

We have three production lines for steel structure fabrication, in order to serve better for abroad project, we buy some advanced machine in our production line, such as the plasma cutting machine.
1. Structural steel fabrication, painting , galvanizing , pre-assembly
2. Designing, fabrication and installation for Prefabricated steel structure building.
3. Deepen or design the fabrication drawing or shop drawing based on your architectural drawing and construction drawing
4. Engineering consulting service
We will provide construction drawing for each project before delivery to guide installation. Our engineers could also come to the construction site to guide installation.
The following question we need to know before making the price. Just feel free to fill what you know.
