Prepainted steel coils, also known as pre-coated steel, color-coated steel coil, or PPGI (pre-painted galvanized iron) coil, have been coated with primer and paint before they are cut, shaped, or formed into final products. This process ensures a uniform paint application, contributing to the material’s aesthetic and functional properties. The coils are commonly made from galvanized or Galvalume steel, which provides a rust-resistant foundation, and the pre-applied paint adds an additional layer of prote...

There are three types of hollow structural sections rectangular Hollow Sections (RHS), square hollow sections (SHS), and Circular Hollow Sections (CHS). Each hollow section has its own set of advantages, properties, and applications. Hollow Circular Sections The first type of hollow structural section was circular hollow sections (CHS). CHS is commonly used in construction, mechanical, and structural applications. They have smooth and clean lines, no sharp or protruding edges, or a lack of sharp or protruding edges. It...

Carbon Steel Pipes are steel pipes with carbon as the main alloy element, and their carbon content is between 0.12-2.0%. Compared with other steel pipes, carbon steel pipes have the following characteristics: ①. High strength: Carbon steel pipes exhibit high tensile strength and yield strength and are suitable for pipeline systems that need to withstand large loads. ②. Wear resistance: Carbon steel pipes have high surface hardness and good wear resistance, and have good tolerance for pipelines transporting hot and cold liquids and abrasive ...
