Prefab Steel Structure Warehouse Metal Building Cost Light Steel Framing Structure
Prefab Steel Structure Warehouse Metal Building Cost Light Steel Framing Structure:
1. The steel structural member has a small cross-sectional dimension, which can effectively utilize the building space, reduce the height of the house, and have a beautiful architectural shape.
2. The portal frame has good rigidity and light weight, and the beam and the column can be assembled, which provides favorable conditions for production, transportation and installation.
3. The amount of steel used for roofing frame is only 1/5-1/10 of the amount of steel used for ordinary steel roof trusses, which is an economical and reliable structural form.
