Galvanized steel pipe comes in two coating types. Choosing correctly affects corrosion life and cost.
Hot-dip galvanized
The pipe is dipped in molten zinc after forming, giving a thick coating inside and out, including the welds and ends. It is the durable choice for outdoor and scaffold tube.
Pre-galvanized
The steel strip is galvanized before the pipe is formed, so the weld seam is less protected. It is lighter and cheaper and suits dry, indoor uses.
Which to specify
- Scaffolding and outdoor: hot-dip
- Indoor framing and lighter use: pre-galvanized
- Coastal or humid: always hot-dip
