Product Feature

High Corrosion Resistance

Pure zinc coating on the exterior wall and stoved epoxy resin finish on the inside protects white conduit from corrosion, even by harsh chemicals and sea air.

Easy and Fast Installation

Precise, sharp threads cut by automated machinery mean fast and easy installation. Precise thread also makes our conduit virtually moisture-tight.

Uniform Quality

Flat steel is rolled, zinc - coated and threaded in one continuous automated process for uniform high quality.
