Galvanized Steel Pipe, is stocked in A53 Tested Pipe up through 6" sch 40 and A500 for sizes 8" to 12" diameters. All pipes have been hot dipped in a zinc rich galvanizing process. Galvanized pipes are a lower cost alternative to stainless steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating. Metals Depot stocks many sizes in precut lengths, full mill lengths or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized pipes can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated. Saw cut ends of our pre-cut lengths are not galvanized and should be treated with a cold galvanizing compound to maintain protection once your project is complete. Any holes drilled or welded areas should also be treated. 8" to 12" sizes may have a 3/4" hole present in ends from the dipping process. All dimensions are before the galvanizing process. All sizes are plain end, not threaded.
