As the manufacturing industry’s demand for large-space, high-load-bearing, and rapidly operational workshops surges, steel workshop exceeding 10,000 square feet have become the core carriers for factory expansion and industrial clusters. Leveraging 20 years of experience in steel structure engineering, Canglong Group provides integrated solutions encompassing design, production, installation, and service, helping global users quickly realize their ideal workshops with precise, efficient, and durable standards.
1. Design
Facing the challenge of large spans exceeding 10,000 square feet, Canglong Group approaches the issue from two dimensions: structural safety and user experience.
Structural Selection: Based on the span (typically 30-60 meters) and load requirements (equipment, goods, wind and snow), a portal frame + truss combination structure or a space frame/shell system is adopted to achieve a column-free, large-space environment (maximum span up to 80 meters), ensuring flexible production line layout.
Material Configuration: Main steel columns/beams utilize Q355B or higher high-strength steel (yield strength 355MPa), while purlins are made of C/Z-shaped cold-formed thin-walled steel, balancing lightweight design with deformation resistance. For coastal/high-corrosion areas, dual protection is provided through weathering steel and hot-dip galvanizing.
Functional Integration: BIM 3D modeling is used to pre-visualize production, storage, office, and auxiliary areas, reserving space for equipment hoisting openings, ventilation ducts, and electrical cable trays. Roof slope (5°-15°) and drainage system are optimized based on local climate.
Compliance Assurance: Simultaneous compliance with local building codes (such as US IBC, EU EN, Middle East SBC) ensures design document approval and avoids rework.
2. Production
Canglong Group’s intelligent production base in Henan, China, transforms on-site construction into factory manufacturing, ensuring the precision and efficiency of large-size steel components.
Modular Manufacturing: Steel columns, beams, and purlins are disassembled into standardized modules according to design drawings (single steel column maximum 12 meters, steel beam segments ≤ 15 meters). Laser cutting, CNC welding, and automatic shot blasting are used to achieve millimeter-level dimensional accuracy (within ±2mm).
Quality Traceability: Each batch of steel is accompanied by a material report. Welded joints are inspected by ultrasonic testing (UT). The galvanized layer thickness is ≥85μm, and the steel does not rust after over 2000 hours of salt spray testing.
Packaging and Transportation: Layered stacking and corner protection are used, increasing container loading capacity by 30% and reducing long-distance transport loss rate to <0.5%, delivering directly to ports worldwide.
3. Installation
Addressing the challenges of numerous components and difficult hoisting in large-space steel workshop, Canglong Group utilizes modular installation to shorten the construction period and reduce on-site risks.
Foundation First: Independent foundations (pre-embedded anchor bolts) are poured according to design drawings, and foundation acceptance is completed within 48 hours, paving the way for steel column installation.
High-efficiency hoisting: Utilizing 25-50 ton truck cranes/crawler cranes, assembly is carried out from the center outwards, with columns first and beams last. 300-500㎡ of steel frame installation can be completed per day. Large-span trusses employ ground assembly and overall lifting technology, reducing high-altitude work.
Safety Guarantee: Dedicated safety officers are on-site, conducting daily pre-shift briefings and weekly safety inspections. 100% of high-altitude workers are certified, and there have been zero major safety accidents in global projects over the past 5 years.
Enclosure Finishing: Color steel roof (0.6mm aluminized zinc substrate + rock wool insulation layer), metal sandwich panel exterior walls, and matching roller shutter doors and PVC windows are installed simultaneously, completing the enclosure system closure within 15 days.
4. Services
Canglong Group goes beyond “turnkey” solutions, providing long-term value.
Operational Training: A “Steel Structure Maintenance Manual” is provided upon delivery, and on-site guidance is provided for daily inspections (such as bolt tightening and anti-corrosion layer repair).
Rapid Response: A service center is established to respond to repair requests within 24 hours and arrive on-site within 72 hours.
Upgrade Support: Pre-installed steel component connection nodes support future additions of floors and expansion of spans at only 1/3 the cost of new construction.
