Pipe and tube
Hot dip galvanised
seamless pipe
SA106 Grade B seamless pipe, hot dip galvanised and supplied screwed and coupled, for water, fire protection and exposed pipework.
Galvanised pipe for exposed and wet service
Our hot dip galvanised (HDG) pipe is seamless carbon steel to ASTM/ASME SA106 Grade B, coated inside and out with zinc for long-term protection against corrosion. It is supplied screwed and coupled, ready for threaded assembly, which makes it a popular choice for fire protection, water, compressed air and external pipework.
We also stock galvanised carbon steel flanges and hot dip galvanised forged fittings to complete the system, all from our site in Kingswinford.

Why hot dip galvanising?
Hot dip galvanising bonds a zinc layer to the steel, which protects it in two ways. It acts as a barrier coating, and it corrodes sacrificially in place of the steel wherever the coating is scratched or cut. For pipework that is exposed to the weather, buried in ducts or carrying water, it gives a far longer service life than bare or painted carbon steel.
Because the pipe is threaded, galvanised systems can be assembled without welding, which avoids burning off the zinc at the joints.
Fire protection and water
Galvanised pipe and fittings are widely used in sprinkler, dry riser and water distribution systems.
