Stainless Steel Corrugated Conduit
Crush-Proof Cable Protection for Rail, Heavy Industry & High-Temperature Environments
Our stainless steel corrugated conduit delivers maximum mechanical protection and EMI shielding for the most demanding environments. Made from SS304 or SS316, it resists crushing, vibration, extreme temperatures, and corrosive agents — making it the standard for rail transit, heavy machinery, and marine applications.
Applications
• Rail & transit vehicle wiring
• Heavy industrial machinery
• Marine & offshore installations
• High-temperature environments
• EMI-sensitive installations
• Chemical processing plants
All stainless steel conduit is manufactured under IATF 16949 and carries CE marking and RoHS compliance.
CE & UL Certified
All heating elements carry CE marking (EU) and UL certification (North America). RoHS and REACH compliant materials standard.

Frequently Asked Questions
What is the MOQ for stainless steel conduit?+
MOQ is flexible — sample lengths, project quantities and full container orders are all handled. Custom-cut lengths and special sizes may carry a practical minimum depending on specifications, which we confirm in the quotation.
Bare or PVC-coated — which should I choose?+
Choose bare SUS 304 conduit for indoor, dry, high-temperature installations where mechanical protection is the priority. Choose PVC-coated (liquid-tight) conduit for outdoor, wet, wash-down or corrosive environments: it provides IP67/IP68 ingress protection with a UV-resistant, UL94 V-0 flame-retardant jacket.
Can sizes and lengths be customized?+
Yes. The range covers AD10 to AD125 for bare conduit (PVC-coated up to AD100), with standard piece lengths and custom cutting available. OEM/ODM requests for special sizes and finishes are welcome.
Can I order matching fittings at the same time?+
Yes — we recommend ordering conduit, fittings and clips together as a system so sizes and IP ratings are guaranteed compatible. See our Fittings & Clips page or simply tell us the AD size and enclosure connection you need.
Are samples available?+
Yes. Sample pieces can be arranged from stock or cut to your required length, depending on specifications, so your team can verify fit and routing before the project order.
What certifications and stock do you have?+
The conduit is CE marked, RoHS compliant and uses REACH-compliant materials, manufactured under IATF 16949. PVC-coated versions achieve IP67/IP68 with a UL94 V-0 jacket. Common sizes ship from our warehouses in Germany and the Netherlands for fast European delivery; production lead time for custom orders is confirmed on the proforma invoice.
What are the payment terms and warranty?+
New customers pay T/T with 30% deposit and 70% before shipment. Products are warranted against manufacturing defects; warranty terms are stated on the proforma invoice, and damage from improper installation or outside the stated temperature range is excluded.
Selection Guide
| Typical Application | Key Considerations | Recommended Selection Direction |
|---|---|---|
| High-temperature industrial lines & welding areas | Heat beyond plastic conduit limits, sparks, abrasion | Bare SUS 304 conduit |
| Outdoor, wash-down or corrosive installations | Water ingress, chemicals, UV | PVC-coated conduit with matching IP67/IP68 fittings |
| Food & beverage and hygienic areas | Cleaning, corrosion from detergents | Bare stainless for washable surfaces, or coated where liquid-tight sealing is required |
| Railway, marine & offshore | Vibration, salt air, long service life | SUS 304 bare or PVC-coated depending on exposure, with matched connectors and clamps |
| Outdoor solar and power cabling | UV, weather, mechanical impact | PVC-coated stainless for maximum protection; see our Balcony Solar Cable Protection Kit |
| Cable pulling on long runs | Inner clearance, bend radius, connector size | Size the AD from the complete cable bundle, including connectors; our team can check the layout |
