Galvanized Steel Pipe is coated by zinc that protects steel from corrosion. It can be used on both commercial and residential areas, including water system, fencing, air condition (HVAC), handrail and guardrail, etc. To satisfy the different needs, our SMC offers several of steel shapes and two types of materials for your choice.

Galvanized steel pipe is a steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. It is also sometimes called galvanized iron pipe.

The process of galvanization was first discussed by scientists in the 1770s, nearly 60 years before it was finally introduced in the 1830s. French engineer Stanislaus Tranquille Modeste Sorel took out the first patent for the process in 1937, and began manufacturing it soon after. By the 1850s, Europe was producing galvanized steel out of manufacturing plants located around the continent. The United States followed shortly thereafter, opening its first plant in the 1870s.

To create galvanized steel pipe, steel materials are placed into a molten bath of zinc. This process is also called hot dip galvanization. The two metals are chemically bound to one another in this process, and will therefore never separate, resulting in a more resistant and longer lasting version of steel.

Packaging of Galvanized Steel Pipe:

Shanghai Metal Corporation provides standard seaworthy packaging to worldwide customers, usually the tubes are packed in bundles, wrapped by plastic bag, fixed by steel strip, and then placed in the container with steel wire fixing. All these packing detail are ensuring your goods safe to your hand during the delivery, we also accept customization for your special requirements. Please feel free to contact us. 

Here are some of the information to help you choose and use Galvanized Steel Pipe:

1. Can be used for carrying water.

2. Commonly used as fencing, scaffolding frame, heating, ventilation and air conditioning (HVAC) on both commercial and residential areas; it can also be used in bridgework and business to make handrail and guardrail, because of its resistance to corrosion, and the strength and durability.

3. Costs more than black steel pipe because of the zinc coating and manufacturing process involved in producing galvanized pipe.

4. Long life time: because of its extremely rigid and strong, it has a lifespan of 40 years.
