• Sale03-QD steel building

A steel hall's components include primary framing (columns, rafters/beams) for main support, secondary framing (purlins, girts, bracing) for roof/wall stability, and cladding/panels (roof/wall sheets) for enclosure, plus essential fasteners, connectors, doors, windows, and sealing closures; all work together to form a durable, functional building.

1.Structural Framework
Columns: Vertical supports transferring loads to the foundation.
Rafters/Beams: Horizontal members supporting the roof and floors, often H-beams.
Bracing: Cables or rods providing stability against wind/seismic forces.

2. Secondary frame & Enclosure & Finishes

Purlins: Horizontal supports for roof panels, running perpendicular to rafters.
Girts: Horizontal supports for wall panels, running perpendicular to columns.
Wall Panels: Steel sheets providing walls, insulation, and aesthetics,
Roof Panels: Steel sheets for waterproofing the roof.
Trimming: Sealing strips for gaps between panels to keep out air/water.
Skylights/Rooflights: For natural light, sometimes with smoke ventilation.

3.Fasteners & Accessories
Fasteners: Bolts, screws, and washers to connect components.
Connectors: Plates and brackets joining beams, columns, and other parts.
Base Plates: Connect columns to foundations.

Doors & Windows: For access, light, and ventilation.

4.Additional Elements
Insulation: For thermal and sound control.
Foundations: Concrete bases secured by anchor bolts.
