This is hot-dip galvanized (HDG) steel pipe certified to TIS 276-2562, the Thai standard for water pipe. Black steel pipe is dipped in molten zinc after forming, so a thick coating protects the inside and outside. We stock the blue-stripe threaded pipe in 1/2–6 in, 2.6–5 mm wall, 6 m lengths.

TIS pipe has a heavier wall. Our blue-stripe Class M HDG pipe runs 1.8–3.2 mm, against 2.6–5 mm here. Choose TIS pipe when the design or the client calls for certified pipe; otherwise see all HDG galvanized pipe.
GI pipe is formed from zinc-coated coil with a thinner coating, and its only TIS standard (107-2566) is for plain-end structural pipe. For water systems choose HDG. See GI galvanized pipe.
The standard covers plain and threaded ends. We stock threaded pipe; ask our team for plain-end pipe.
