A high-strength galvanized steel roller shutter door for secure warehouse exteriors and factory walls — the toughest, most economical rolling steel door in the RAX range.
Maximum tensile strength at the lowest material cost — the workhorse rolling steel door for demanding exterior openings.
The galvanized steel roller shutter door (industrial rolling steel door) is RAX’s workhorse shutter for warehouses, factories, logistics hubs and exterior wall openings where strength, security and long-cycle durability come first. Built from galvanized steel sheet in the 0.4–1.5 mm range, it pairs the tensile strength of steel with a zinc coating that resists corrosion outdoors and in humid environments — without the material premium of stainless or aluminum.
RAX produces every galvanized steel shutter to your exact opening and specification, manufacturing the curtain, barrel, guides, tubular motor and springs in-house. Each unit is validated against the 100,000-cycle fatigue protocol and ships with wiring diagrams and an English manual so your local team installs without guesswork.
RAX-company facts on this page — materials, 100,000-cycle fatigue testing, certifications held, warranty and lead time — are from RAX Door Technology’s approved brand brief. Industry figures are marked [SOURCED] (with the source) or [ESTIMATE] (industry-typical, not independently verified) in the Basis column and are confirmed against your opening on the technical layout. Fire resistance (EI60/EI120) and wind-load class are project-specific capabilities we test and document per order — never blanket certificates.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification.

Galvanized steel offers the highest tensile strength at the lowest material cost – ideal for high-security warehouse exteriors and factory walls. Aluminum is about one-third the weight and better for coastal or humid environments; stainless 304/316 is the premium choice for food, pharma washdown or chemical plants. All three are available from RAX with the same custom engineered to your specification.
The EN 12424 classification runs from Class 0 (no wind-load performance) to Class 5 (above 1,000 Pa). Standard industrial exterior shutters typically achieve Class 2-3; wind-rated builds reach Class 3-5. RAX markets Wind Load Class 5 Certified – the specific class per shutter model is confirmed with the EN 12424 test report.
Any opening within the roller shutter range – large industrial doors from prototype to container-load, full flexibility on order quantity. Typical CN-export industrial steel shutters reach roughly W6,000-8,000 mm x H5,000-6,000 mm; wider openings use multiple shutters or heavy wind-rated guides. Share your opening and we confirm the feasible span and produce a technical proposal.
