Hot dipped galvanized carbon steel pipes
Hot-dipped galvanized steel pipe starts with a steel blank which will be dipped into a pot or tank of molten zinc. This process is often referred to as hot-dip galvanizing. During the process, a chemical reaction is triggered between the molten zinc and steel surface. The result is that a tightly-bonded zinc-iron alloy coating is formed on the surface to make the steel more resistant and longer lasting.
Outdoor fences or handrails will be often exposed to the corrosive environment on a day-to-day basis. This almost necessitates the use of the hot-dip galvanized pipe that has a highly corrosion-resistant coating. Galvanized pipe can be round tubular pipe, square hollow section pipe, rectangualr hollow section pipe, oval-shaped pipe etc.
Please note
Our hot-dip galvanized pipe is not recommended for acid or alkali environment.
