Also specified as: Corrosion-Resistant Stainless Steel Industrial Door — 304/316 stainless doors for hygiene, washdown and aggressive environments.
A corrosion-resistant industrial door built from stainless steel 304 or 316 for food, pharma, marine and chemical environments where coated steel corrodes. Custom built from prototype to container-load, full order flexibility, with full technical and CE documentation.
Where washdown, salt or chemicals are present, coated steel eventually rusts. Stainless steel does not — and that is what this door is built for.
Panels, frames and hardware are fabricated from stainless steel 304 for general hygiene duty or 316 for marine and chemical exposure, where molybdenum-bearing grade resists chlorides and aggressive cleaning agents. The result is a door that survives daily washdown, salt air and process chemicals without the coating failures that shorten the life of painted steel.
Configuration follows the application: sectional overhead, sliding or high-speed doors can all be built in stainless, with food-grade silicone seals and easy-clean detailing. As a full-category manufacturer, RAX produces panels, hardware and operators in one factory and validates every door through a 100,000-cycle fatigue protocol before shipping.
RAX company facts are from the approved brand brief. Industry-typical values are labeled in the Basis column and confirmed against your technical layout.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification.
| Parameter | Specification | Basis |
|---|---|---|
| Door Type | Sectional overhead, sliding or high-speed configuration in stainless steel. | Per project |
| Grade | Stainless steel 304 (general hygiene) or 316 (marine / chemical / chloride). | RAX |
| Opening Size | Made to order; large industrial openings engineered per configuration. | Per project |
| Panel | Stainless skins over 40–50 mm PU foam core for insulated builds; solid sheet for non-insulated. | RAX-measured |
| Thermal Performance | Insulated build supporting up to U-value 0.33 W/m²K panel-level thermal performance. | Marketing value |
| Corrosion Resistance | 316 grade resists chlorides and aggressive cleaning agents for washdown and salt-air duty. | Industry-typical |
| Cycle Life | 100,000 cycles validated in the RAX fatigue test lab. | RAX-measured |
| Operation | Electric operator with servo / VFD drive; radar, geomagnetic and light-curtain sensing optional. | RAX |
| Sealing | Food-grade silicone rubber seals; easy-clean profiles with minimal ledges. | RAX |
| Finish | Brushed / mirror polished stainless; full RAL PVD or coating on request. | RAX |
Grade selection (304 vs 316), configuration and sealing are confirmed on the technical layout we issue before production — matched to your environment.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching/bending centre.
Match the door to the opening duty — keep each card to one line.
Your installers get the full document set before the door ships.
Certificates we hold today, and the project-specific test data we arrange against the matching standard.
Rigorous 100,000-cycle fatigue testing protocols, validated galvanized steel and aluminum alloy materials, and precision servo-drive manufacturing — documented on every order.
Large industrial doors from prototype to container-load delivery.
OEM/ODM is the core of what we do: grade selection, configuration, opener matching and manual translation are all tailored to your environment and market — under NDA protection.
From custom engineering to container-load delivery — the document set your local installers need.
Door body 2 years · operator / motor 3 years (servo motor 5 years) · free spare parts within warranty, DHL/FedEx 5–7 days · tooling & technical drawings archived up to 5 years.
Grade 304 suits general hygiene and washdown duty in food and pharma plants. Grade 316 adds molybdenum for resistance to chlorides and aggressive cleaning agents, so it is the right choice for marine, coastal and chemical environments. Tell us the exposure and we recommend the grade.
Sectional overhead, sliding and high-speed doors can all be fabricated in stainless steel with matching stainless hardware. We select the configuration to suit your opening size, traffic duty and hygiene requirements.
Yes. Stainless skins can be built over a 40–50 mm PU foam core for thermal and acoustic separation, supporting up to U-value 0.33 W/m²K panel-level thermal performance, or supplied as solid sheet where insulation is not needed.
Panels, hardware and operators are validated through a 100,000-cycle fatigue protocol in our in-house test lab, with stainless running gear sized to the door weight for corrosion-free, low-wear operation.
Yes. We hold CE to EN 13241 and EN 12453 for operator safety, backed by ISO 9001:2015 and SGS material reports covering the stainless steel substrates. A Declaration of Conformity and test report ship with every order.
Every door is custom-engineered to your specification. Samples run 7–15 days, a standard container 12–20 days, and a first custom order 20–35 days (repeat orders 15–20 days). FOB ports are Tianjin and Qingdao, FCL and LCL.
Door body is covered for 2 years and the operator / motor for 3 years (servo motor 5 years). Free spare parts within warranty ship by DHL/FedEx in 5–7 days, and OEM projects are protected under NDA.
Send your opening size and environment — we return the grade recommendation, technical layout and container-ready quotation.
