These days, welded pipes can be found in nearly every industry. Because welded pipes usually have tighter dimensional tolerances than seamless steel pipes. They are more stable because its corrosion resistance. Meanwhile, welded tubes and pipes are generally more cost effective than the equivalent seamless versions as well. Therefore welded pipe is a great choice of piping product for many different industries such as petrochemical, desalination, oil & gas and chemical processing.

Steel pipe structure building is a new type of energy-saving and environment-friendly building system, known as the "green building" of the 21st century. Steel pipe structure building is a building structure with light weight, high strength, good seismic performance, energy saving and environmental protection, and can be recycled, which meets the requirements of developing energy-saving buildings and sustainable and healthy economic development.

Perforated steel sheet is often galvanized for increased corrosion resistance. Galvanizing is a process that involves coating the steel sheet with a thin layer of zinc. The zinc acts as a barrier, protecting the steel from corrosion and oxidation. The added corrosion resistance makes galvanized perforated steel sheets an ideal choice for outdoor applications, such as stair treads, fence panels, and protective grates.

According to the manufacturering process, there are two types of metal, the hot roll metal and cold roll metal. What are the difference between the two types of metal sheet? The mainly difference is temperature. The hot roll steel is made under the high temperatures. The cold roll steel bascially is
