STEEL PIPES (ERW, SPIRAL, SEAMLESS)

Black Iron Pipes and Galvanized Iron Pipes are commonly used pipes in general contracting of both commercial buildings and homes not only for conduits for liquid but for building support as well.

Black Iron Pipes, what we often refer to simply as steel pipes, are uncoated iron pipes. Because they are uncoated and made without seams, they are generally used to carry propane or natural gases through them. They are also used in general contracting for scaffolding, fences and other forms of building support.

Galvanized Iron Pipes are coated with zinc making them more resistant to corrosion. An added benefit of the zinc is that it also prevents buildup of mineral deposits that may cause pipes to clog. Because of its resistance to corrosion, GI Pipes may be used for carrying water both to homes and commercial buildings.

Both types of pipes are available in Standard and Commercial quality, depending on your need.
