FAQ
What are the advantages of double deck corrugated conduit compared with single-layer conduit?
Its dual-layer interlocking design provides stronger protection against dust, oil, and abrasion. It also offers better weather resistance, is less prone to aging or cracking, and delivers enhanced mechanical strength for long-term use.
Is the double deck corrugated conduit more wear-resistant?
Yes. The outer layer is thicker and designed to withstand friction, vibration, and mechanical impact, making it more durable than standard single-layer conduits.
Is the conduit still flexible even with a double-layer structure?
Yes. The design maintains excellent flexibility. The outer layer provides protection while the inner layer offers smooth bending performance, keeping the bend radius similar to standard conduits.
Is the double deck corrugated conduit waterproof?
The interlocking structure offers basic water resistance. For higher waterproof performance, it is recommended to pair the conduit with waterproof connectors or fittings.
Do you offer OEM/ODM services?
Yes. We support customized materials, colors, lengths, flame-retardant grades, printing, packaging, and full OEM/ODM solutions for cable assemblies, machinery manufacturers, and engineering projects.
