Construction
Square Lock construction is highly flexible steel conduit made by helically winding of cold rolled annealed and pinch passed mild steel strips with sheared edges. Hot dipped galvanized steel stripe is used where high corrosion resistance and long life for the conduit is required. These conduits are used for applications where high flexibility is required.
Application- As mechanical protection for insulated electrical cables and wires which may be exposed to normal atmospheric conditions.
- As decorative flexible tube for bathroom fittings and interiors.
- As protective covering for rubber and plastic tubing in domestic gas appliances such as burners, ovens and gas water heaters.
