50+ Years Lifespan Customizable Dimensions Crane Beam Steel Structure with Bolt-Connected Assembly

Our crane beam steel structure factory workshop combines simple design, large clear span, high strength and quick installation, purpose-built for heavy industries requiring overhead crane operation — machinery manufacturing, steel processing, automotive plants, logistics centers and warehouses. Prefabrication significantly reduces on-site construction time and overall cost.

The main frame consists of welded H-beam columns and crane beams made of high-grade Q355B structural steel, providing high rigidity and load capacity. The structure supports overhead cranes from 1 ton up to 300 tons, with crane beams precisely engineered to carry heavy lifting loads while maintaining stable structural performance.

Galvanized C/Z purlins, angle steel, tie rods and pipe bracing form the secondary structure, delivering excellent lateral stability and wind resistance for the whole building.

Color steel sheets or sandwich panels (EPS, PU, rock wool, glass fiber, 50-250mm) provide thermal insulation, waterproofing, sound insulation and corrosion resistance, keeping a stable indoor environment for production and storage.

Shot blasting Sa2.5 followed by double-layer epoxy primer, or hot-dip galvanization for coastal and humid areas, ensures excellent anti-corrosion performance and a service life of 50+ years.

All steel components are cut, drilled, welded, rust-proofed and painted in our factory with precision equipment, then delivered for 100% bolted assembly on site — no on-site welding required. Lightweight yet strong, this prefabricated system reduces material waste and shortens build time by 30-50% compared with traditional construction.

Standard design drawings include layout, component details and installation specifications, engineered with PKPM, Tekla Structures, CAD and BIM simulation software to GB, AISC (USA) and Eurocode standards, ensuring safety and quality in any region.

Comprehensive after-sales support: 5-year warranty on the main structure, installation drawings and videos, online guidance, remote or on-site engineer consultation, and spare parts supply for long-term use.

CE and ISO certified, with third-party inspection (SGS/BV) available before shipment. Proven projects include a 9,200㎡ steel grid project in Uzbekistan, a 148,000㎡ high-rise project in Anqing, and 1,300 containers supplied for the 60,000-seat Kenya Talanta Sports Stadium.

• Main steel structure (beams, columns, crane beams): loaded on custom brackets with rubber protectors covering edges and reinforced strapping to prevent deformation, paint peeling and abrasion during sea transport.
• Fasteners and small accessories: packed in fumigated boxes with moisture-proof paper and desiccant to prevent rust.
• Roof and wall panels: stacked with foam pads and wrapped in waterproof tarpaulin against corrosion and rain.
• Professional container loading with wooden blocks and steel wires secures cargo; inspection and packing lists are available.
