Stainless Steel Industrial Door

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.

01 · Overview

Why Buyers Specify This Door

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.

Should I choose 304 or 316 stainless steel?

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.

Which door types are available in stainless?

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.

Can the door be insulated?

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.

What cycle life can I expect?

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.

Is the door CE certified?

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.

What are the lead time and warranty?

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.

What warranty and spare parts support do you offer?

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.
