Q235 Q355 Engineered Metal Building For Industrial And Commercial
Product Description
Pre-engineered steel structure buildings for industrial and commercial projects consist of primary members, secondary members, roof and wall cladding, and various other components. These structures can be customized with additional features including skylights, wall lights, ventilation systems, doors & windows, mezzanine floors, crane systems, and insulation based on customer requirements. Engineered for lightweight durability and superior strength, these steel buildings offer exceptional flexibility and adaptability for modern construction needs.
Product Parameters
Components of pre-engineered steel structure building:
- Primary Framing Elements: Columns and beams made from H-section steels (hot rolled or welded), featuring factory primer, painted or galvanized surfaces for enhanced rust resistance.
- Secondary Framing Elements: Purlins and tie bars that secure to columns and beams with common bolts.
- Bracing: Round steel knee bracing and supporting parts to improve structural stability.
- Cladding: Roof and wall coverings using color-coated corrugated steel sheets or sandwich panels with zinc-aluminum coating for weather protection and aesthetic appeal.
