GI pipe (galvanized iron pipe) is bare steel pipe coated with a layer of zinc metal through a molten zinc bath, giving it natural corrosion resistance, including in outdoor and exposed conditions. Hotline Steel Trading L.L.C. is a specialized stockiest importer and exporter of GI pipe in the UAE, supplying sizes from 1/2 inch to 8 inches to meet standard construction and industrial piping requirements.

GI pipe, also known as galvanized steel pipe, is produced by applying a zinc coating to steel pipe through hot-dip galvanizing. The zinc layer acts as a sacrificial barrier, corroding in place of the underlying steel when exposed to moisture or air, which extends the service life of the pipe compared to uncoated (black) steel pipe. This is general industry education about GI pipe as a product category, not a claim specific to Hotline’s own manufacturing process, since Hotline is a stockiest importer and exporter rather than a manufacturer.

GI pipe is used wherever steel pipe needs corrosion resistance without the cost of stainless steel, including water lines, structural framework, fencing, and fire protection piping.
Hotline Steel supplies GI pipe from 1/2 inch to 8 inches, in line with BS 1387 Class B & C and ASTM A53 Class A Schedule 40.
GI pipe has a zinc coating applied through hot-dip galvanizing, which gives it corrosion resistance that uncoated (black) steel pipe does not have.
GI pipe is the straight pipe itself; GI fittings are the elbows, tees, couplings, and other components used to connect and route GI pipe.
