C-shaped steel is made by hot rolled plate and cold bending. It has thin walls and light weight, excellent cross-section properties and high strength. Compared with traditional channel steel, the same strength can save 30% of materials. It is also named because its cross-section is the same as the English letter "C". The company uses imported forming machines to roll C-shaped steel. The product has a smooth surface and high size accuracy. Z-shaped steel is named because its cross-section is the same as the English letter "Z". In addition to its high strength and excellent properties such as saving steel, Z-shaped steel is particularly convenient and fast to install. Z-shaped steel is used to connect roof color panels (tiles) and wall maintenance panels of steel structure factories (hence also commonly known as purlin).
