Project Case: 18×36m Open-Front Steel Shed in Spain
Project Overview:
This project involved the design, fabrication, and supply of a
customized open-front steel shed (Dimensions: 18m width × 36m depth
× 4m height) for a client in Spain. The structure features
three-sided cladding (with one 36m side fully open) and a complete
roofing system, ideal for industrial storage, logistics, or
workshop use.
Why This Solution Worked
Customization: The open-front design met the client’s need for
unrestricted access and airflow.
Durability: SA 2.5 shotblasting + dual-layer painting and galvanized purlins ensure longevity in harsh conditions.
Cost-Efficiency: Pre-fabricated components reduced on-site labor time and costs.
Full Package: All accessories (drainage, fasteners, sealants) were included for seamless installation.
| Category | Specifications | Purpose/Advantage |
| Main Structure | Q355B H-Beams (fabricated, cut, assembled, rectified) | High-strength frame for structural integrity and load-bearing capacity. |
| Surface Treatment | Shotblasted to SA 2.5 grade; primer: red-lead paint, topcoat: mild-grey paint | Superior corrosion resistance, suitable for industrial environments. |
| Cladding | Roof & Wall: 0.5mm single metal sheets; Galvanized C180×2.0mm purlins | Lightweight yet durable; galvanized purlins prevent rust and extend lifespan. |
| Design | Open-front (36m side) + three-sided walls | Optimal accessibility for vehicles/machinery and natural ventilation. |
| Fasteners | M20 (10.9S) high-strength bolts; M24×850mm anchor bolts; M12/M16 bolts | Secure connections; anchor bolts provide stability against wind/uplift forces. |
| Accessories | Φ12 tied rods, ridge caps, gutters, Φ110 downpipes, screws, rivets, silicone | Complete weatherproofing and drainage solution; ensures structural rigidity. |
