Galvanized steel pipe applications

Galvanized steel pipe has a wide range of applications today because of advantages in projects, such as 1) low initial cost, 2) low maintenance, 3)long service life, 4) easy to use and so all.

In practical applications, round steel pipe and square steel pipe are often seen as one of important building materials in the construction trade. When it comes to construction projects, steel tubes are used in many building types from small storage units to skyscrapers in big cities. For example, they are used to create the foundation of large buildings as well as other framework. In addition, rectangular steel pipe is one popular member of hollow section pipes which are metal profiles with square or rectangular tube section. Rectangular hollow sections are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. ASTM A500 is the most common steel specification for hollow structural section widely used in construction today.

Today, China hollow section tubes also offer advantages of corrosion protection in applications. Some hollow sections have rounded corners resulting in a better protection than that with sharp corners. Compared to other traditional construction materials, structural steel frame is stronger because it was further enhanced by steel reinforcing process. The increase in its standard strength is greater than the total strength of other competing highly strong materials. Hot dipped galvanized steel pipe has been considered popular a lot among many users today. For the one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratch, which makes the steel look more attractive.

Pre galvanized steel pipe is one popular type of galvanized steel pipe in the market today, which was galvanized while in sheet format, thus prior to further manufacturing. Pre-galvanization is also known as mill galvanized, due to the fact that the steel sheet is rolled through molten zinc. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled. A specific thickness is applied to the entire sheet, for example pre-galvanized Z275 steel has a 275g per square meter zinc coating. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance.
