Hot-dip galvanized steel pipe models are divided into two types: JDG pipes and KBG pipes. Both are the same in all aspects except for the connection method.

JDG pipes (screwed and fixed type galvanized steel conduits, rigid metal flat conduits for electrical installations) are a new type of protective conduit for electrical wiring. The conduit system is assembled using screw-tightened connection technology for the connecting sleeve and its metal accessories, eliminating the need for cross-earthing, welding, or threading. The appearance is silver or yellow. The JDG series steel pipes are selected with double-sided hot galvanized treatment on thin-walled steel plates, providing 360-degree maintenance.

KGB pipes, also known as sleeve crimped galvanized steel conduits, are made with sheets and feature a double-sided hot-dipped galvanized coating for 360° protection. They are processed using advanced technology and are protected by a double-sided hot-dipped galvanized finish.

Corrosion-resistant applicable environment:

Suited for: electrical and control line protection piping projects in dry ventilation areas of buildings for lighting, fire prevention, security, video, communication, etc. Generally has moderate corrosion resistance; not suitable for exposure to acid rain or for outdoor areas in southern climates or humid locations.
