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.
Value Delivered
Quick Deployment: Pre-engineered components enabled fast assembly.
Low Maintenance: Robust materials minimize future upkeep.
Compliance: Materials and processes align with European industrial standards.
