Round, square and rectangular pipes in mild steel and galvanized finish, in every standard gauge and length — from stock in Lahore and Karachi.
MS (Mild Steel) pipe is made by forming hot or cold rolled steel strip into a tube and welding the seam along its length — the process known as ERW, electric resistance welding. The result is a straight, dimensionally consistent tube suitable for structural, water and general fabrication use.
GI (Galvanized Iron) pipe is the same mild steel pipe after hot-dip galvanizing, in which the finished tube is immersed in molten zinc so that both the inside and outside surfaces are coated. That internal coating is what makes GI the standard choice for potable water lines and for any pipework exposed to weather, where plain MS would rust from the inside out.
Pipe is specified by nominal bore (NB) rather than by its actual measured diameter, and by wall thickness — often quoted as a gauge number in the local market. A heavier gauge for a given bore means a thicker wall, a stronger pipe and more weight per length.
