Product basic Info
Gi pipes are made of pre-galvanized steel strips. The pre-galvanized steel strips welded into round tubes then to square or rectangular tubes. We have passivation progress to avoid rusting.

Our Processing
Our factory has strong technology for further process of steel pipes.
Cutting
We offer precision cutting on lengths of pipes with wide range. The type of cutting used depends on both the size of the pipe and the required precision.
Beveling
We can apply any type of bevel to any degree required. Beveling can be applied to the face of any size or diameter of pipe.
Threading
Threaded pipes can provide an effective seal for pipes transporting luquids, gas, steam and hydaulic fluid. We can thread any length of pipe in diameters ranging from 1/8''-8''. Tapers are available are NPT, BSPT, NPS, 3/16'' peerless, and 8 round taper.
Grooving
Roll grooving can be done in any style according to industry standards. It can be applied to any length of pipe ranging from 1''-12'' diameters.
