Keep goods, vehicles and people dry at every door. Our outdoor steel canopy frames combine H-section steel columns with I-beam headers for high wind resistance, topped with impact-resistant polycarbonate sheeting that lets daylight through while blocking rain. Fully hot-dip galvanized, the structure stays rust-free for years of outdoor service with essentially zero maintenance.
Key Features
Wind-resistant structure: H-section steel columns plus I-beam headers carry wind loads confidently - engineered for exposed outdoor sites.
Polycarbonate roofing: ≥ 4 mm solid PC sheet offers high light transmission and outstanding impact strength (hail, falling debris).
Full hot-dip galvanizing: every member galvanized to AS/NZS 4680 for long-term rust protection outdoors.
Custom spans: clear spans from 3 to 8 metres to suit door openings, dock aprons and parking bays.
Typical Applications
Logistics warehouse loading dock shelters
Factory gates and main entrances

Frequently Asked Questions
Q1: What is the maximum clear span?
Standard engineering covers clear spans from 3 to 8 metres. For wider coverage we can add intermediate columns or design a custom truss - tell us the requirement and site conditions.
Q2: Can the canopy handle high wind and snow loads?
Yes. The H-section column and I-beam header structure is engineered for exposed outdoor sites. Provide your local wind and snow load requirements and we will size members to match.
Q3: How durable is the polycarbonate roof?
The roof uses ≥ 4 mm solid polycarbonate sheet with high impact resistance against hail and debris, and high light transmission so the area below stays bright without artificial lighting.
Q4: Can you include drainage and lighting?
Yes. We can integrate gutters and downpipes into the frame, plus LED lighting strips for night operation at loading docks and entrances.
Q5: How is it installed?
The canopy ships as welded sub-assemblies with bolted site connections, anchored to your concrete foundation with standard anchors. We supply anchor layout drawings with every order.
