Thickness 20-50 mm Spiral Perforated Tube Galvanized Steel Custom Length
Perforated pipe can be made of mild carbon steel sheet, aluminum steel sheet or stainless steel sheet. It is punched into flat sheet and then fabricated into pipe. The fabrication method can be welded and lock seam.
Lock seam perforated pipe is made by folding up the overlapping edges against each other, then folding them over in the same direction a number of times. It has flush surface outside and lock seam inside.
Welded perforated pipe is manufactured by perforated metal sheet which is cut to desired size and then rolled and welded into a tube.
