Prefabricated Heavy Duty Steel Workshop With Overhead Crane Machinery Factory

Our heavy-duty prefabricated steel structure factories are engineered for high-load industrial production, heavy machinery operation, and large-scale manufacturing facilities. Built with reinforced rigid steel frames and premium grade structural steel, these industrial buildings withstand continuous equipment vibration, heavy overhead crane operation, and extreme outdoor weather conditions.

All building components are pre-manufactured in our modern workshop using advanced processing technology and professional anti-corrosion treatment. Compared to traditional concrete buildings, our steel factories feature simpler foundation requirements, faster installation, and superior structural flexibility. We deliver reliable, cost-effective, and long-lasting industrial building solutions for global heavy industry clients.

Main Frame: Utilizes heavy-duty H-section steel lattice columns arranged in a cruciform configuration, forming a robust, integrated rigid frame structure with exceptional impact resistance and structural rigidity.

Steel Grade: Standard configuration features Q235B and Q355B grade steel.

Surface Protection: Offers dual-protection scheme comprising multi-layer anti-rust coating or hot-dip galvanizing for long-term corrosion resistance.

Column Spacing: Standard spacing options are 6m, 7.5m, and 9m; customizable to meet specific project requirements.

Wind and Seismic Resistance: Designed to withstand wind forces up to Grade 12–14, and complies with international Grade 8 seismic standards.

Auxiliary Structure: Equipped with complete set of crane beams, horizontal bracing, tie rods, and purlins to enhance overall structural stability.

Enclosure System: Features corrugated steel sheeting, or rock wool/PU insulated sandwich panels, offering superior waterproofing, fire resistance, and thermal insulation properties.

• High Load-Bearing Capacity for Heavy Workloads
  Reinforced box columns and thickened H-beam main frames serve as the primary structure. The entire building is fully reinforced to carry overhead cranes from 5 tons up to 50 tons. Operates steadily under long-term heavy pressure and mechanical vibration, perfectly meeting the demands of heavy industrial production lines.
• Expansive Open Interior Space
  Optimized structural design removes unnecessary intermediate columns. Single clear span ranges from 15m to 36m, with combined multi-span designs reaching larger sizes. The wide open space allows flexible layout of large production machines, assembly lines and cargo handling areas, greatly improving operational efficiency.
• Excellent Durability & Weather Resistance
  Multiple protection processes including shot blasting, multi-layer anti-rust paint or hot-dip galvanizing are applied to all steel components. The structure is anti-rust, anti-corrosion, wind-proof and earthquake-resistant. Operates stably in high temperature, heavy snow, strong wind and humid environments, adaptable to diverse geographical conditions worldwide.
• Time & Cost Saving Construction
  Most components are finished inside the factory, limiting on-site work to assembly only. The construction period is greatly shortened, enabling your factory to start production much earlier. The lightweight steel structure reduces foundation investment and overall project budget effectively.
• Flexible Customization & Expandability
  We provide one-stop customized service on building dimensions, eave height, column spacing, wall and roof claddings. Crane beams, ventilation systems, fireproof facilities, doors and windows can be arranged as per your actual demands. The steel building is easy to extend or reconstruct for future business expansion.
• Green & Low Maintenance
  Structural steel is fully recyclable and eco-friendly. Matched insulated panels provide excellent heat insulation and sound insulation, reducing daily energy consumption. The integrated rigid frame structure resists deformation. Routine maintenance is simple with low long-term operating costs.

• Rich experience in designing and manufacturing heavy-load steel industrial buildings, familiar with international building codes of different regions.
• Strict full-process quality inspection: raw material test, welding inspection and anti-corrosion test are carried out before delivery.
• Competitive overall cost: lower foundation cost, labor cost and maintenance cost compared with traditional buildings.
• Mature export system, experienced in cross-border transportation and export formalities.
• Full chain service from design, production to delivery and after-sales, saving you time and worry.
