Heavy Steel Structure Factory Pre-fabricated Workshop And Industrial Plant

Our heavy-duty steel structure factory buildings are professionally engineered for heavy industrial production, mechanical processing, manufacturing, and large-scale industrial operation scenarios. Different from light steel workshops, this series adopts thickened H-beams, box steel columns, and reinforced steel frames, supporting heavy crane loads, long-term equipment vibration, and harsh outdoor working environments.

All structural components are fully prefabricated in our factory with precise CNC processing, strict anti-corrosion and rust-proof treatment, and fast on-site assembly. Featuring large span, high load-bearing, strong stability, and long service life, these industrial steel buildings fully comply with international building standards, ideal for global industrial construction projects.

• Main Structure: Heavy-duty H-section steel, box steel column, lattice steel frame, high structural rigidity, strong impact resistance
• Steel Grade Option: Q235B / Q355B high-strength structural steel, European standard S235JR / S355JR optional
• Anti-Corrosion Treatment: Shot blasting rust removal + primer + intermediate paint + topcoat / hot-dip galvanizing treatment
• Standard Bay Distance: 6m / 7.5m / 9m customizable
• Wind Resistance Level: Up to Level 12-14 wind resistance
• Seismic Grade: Meet international 8-degree seismic design standard
• Support System: Equipped with crane beam, tie rod, support, purlin and full auxiliary structure to ensure overall stability
• Enclosure System: Color steel single sheet / rock wool / PU thermal insulation sandwich panel, fireproof, waterproof and heat insulation

• Heavy Load Capacity: Built with Q355 high-strength steel, thick box columns and H-beam frames. Supports 5T-50T overhead cranes, withstands mechanical vibration and heavy loads, outperforming ordinary light steel workshops.
• Large Clear Span & High Space Efficiency: Single span 15m-36m, multi-span over 100m on request. Column-free interior suits large machinery, production lines and cargo handling for maximum space use.
• Strong Durability & Climate Adaptation: Hot-dip galvanizing plus multi-layer anti-rust coating delivers excellent corrosion, wind and earthquake resistance. Works reliably in extreme weather globally.
• Rapid Construction & Fast ROI: 90% factory prefabricated for on-site assembly only. Construction time cut by 40%-60% vs concrete buildings, enabling early production and quicker returns.
• Long Lifespan & Low Maintenance: 50-year design life. Rigid frame resists deformation and cracks. Simple daily upkeep lowers long-term operational costs.
• Fully Customizable & Versatile: Customize span, height, materials and more. Pre-installed interfaces for crane, ventilation, lighting, fireproof and insulation systems for diverse industrial workshops.
• Eco-Friendly & Energy Saving: 100% recyclable steel. Insulated sandwich panels provide heat and sound insulation, complying with global green building standards.
