Q235B Q355B Heavy Steel Structure Building with 50-200mm Sandwich Panels and Custom Clear Spans

Custom-engineered heavy steel structure buildings for industrial and commercial applications, featuring primary members, secondary members, and comprehensive roof and wall cladding systems. These versatile structures can be enhanced with various additions including skylights, ventilation systems, doors, windows, trusses, mezzanine floors, and crane systems based on specific project requirements.

Main steel frame composed of beams, columns, and trusses fabricated from Q235B and Q355B steel sections or welded steel sections. All components undergo rigorous rust removal and anti-rust processing including shot blasting, painting, and galvanizing. Connection methods include welding, bolts, or rivets for structural integrity.
