Product Description
What Is Pre-galvanized Steel Pipe?
Pre-galvanized pipe is a kind of steel pipe which is welded with galvanized steel strip. Generally the wall thickness is thin, and the amount of zinc is controllable, generally in 30-150 g/㎡.
Distinguishing Feature
With gleaming white and reflective, there is very few snowflake shapes on the pipe body. And the two ports are clean and no zinc tumor.
Pre-galvanized steel pipe is cheap and economical with corrosion resistance. But the effect is worse than that of hot dipped galvanized steel pipe. And the service life (5-7 years) is shorter than that (8-10 years) of hot dipped galvanized steel pipe.
Application
It is mainly used for Greenhouse construction, greenhouse steel pipe, Steel canopy, Steel workshop, Grid steel pipe, Parking shed, Stair handrail, Balcony railing, Guard rail, Leisure furniture, Amusement facilities, Fitness equipment, Air conditioner heat sink, Threading pipe, Wire protection tube, Lighting room steel pipe and etc.
