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. |
Packing and Shipping:
Product Packaging:
All the steel structure components will be packed in bundles and secured with steel belts or ropes to prevent damage during transportation.
Wall and roof panels will be packed in wooden crates to avoid scratches and dents.
All the fittings and accessories will be packed in cartons or bags.
Customized packaging is available upon request.
Shipping:
We have a professional logistics team to ensure timely and safe delivery of the steel structure to the construction site.
We can ship by sea, by land, or by air depending on the customer's requirements.
We will provide the customer with all the necessary documents and tracking information to ensure a smooth delivery.
Installation Process Explained
Our steel structure building installation follows a standardized and efficient 12-step process:
1-2 Foundation
- Prepare the concrete base according to the structural load requirements and install the pre-embedded anchor bolts as per the foundation construction drawings.
3-4 Columns
- Erect the steel columns using a truck crane, with one worker guiding and 3-4 workers assisting. Secure each column onto the anchor bolts and add temporary bracing.
5 Roof Beams
- After two adjacent steel columns are installed, begin installing the main roof beams to connect and stabilize the structure.
6-7 Purlins
- Install roof and wall purlins after completing the column and beam installation. Bolt them securely onto the main structure to support cladding panels.
8 Purlin Rods
- Reinforce the frame by installing horizontal tie rods between purlins for added stability.
9 Water Gutter
- Install the gutter system along the eaves to ensure proper drainage and prevent water accumulation.
10-11 Cladding
- Attach wall sheets to wall purlins with self-tapping screws, then install roof sheets. For insulated buildings, fix sandwich panels to both walls and roof.
12 Completion
- Install covers at corners, eaves, windows, and doors; fit windows and doors in place; conduct a final inspection - your steel building is ready for use.
