H-Section Steel Structure Building for Industrial Workshops and Warehouses

Steel structure building has features of high fire resistance and strong corrosion resistance. The main bearing components are composed of steel, including steel columns, steel beams, and steel roof trusses, connected by welds, bolts, or rivets.

The roof and wall can be made of composite panel or veneer. Galvanized sheet metal prevents rust and corrosion. Self-tapping screws ensure tight connections between plates to prevent leakage. Composite panels with PU, EPS, fiber glass, or rock wool insulation provide excellent thermal and fire-retardant properties. Brick walls can also be used for steel structure maintenance.

Applications include large-scale workshops, warehouses, supermarkets, entertainment centers, and modular steel structure garages.
