STEEL CONDUIT SERIES
Product Introduction
This pipe is made from conventional hot-dip galvanized steel strip from small and medium-sized steel mills, cut longitudinally, welded, and zinc-sprayed. (Double-sided zinc coating approximately 60g/m² ±10%).
Product Features
(Smooth, Bendable, and Corrosion-Resistant)
1. Internal welds have minimal burrs, and both ends of the pipe are flat-trimmed, ensuring no damage to the insulation of wires.
2. The steel grade is suitable for cold bending, resulting in minimal wear and tear and the ability to withstand light pressure.
3. Its corrosion resistance is average. It should not be exposed to acid rain or used outdoors in southern climates or in humid locations.
Product Applications
Suitable for electrical wiring and piping projects in dry and ventilated areas of general residential, industrial, and commercial buildings.
