Steel Structure Warehouse Design and Construction

Several Steel Characteristics Commonly Used in Tianchen Steel Structures (1) Hot rolled section steel includes angle steel, I-beam, channel steel T-shaped steel Z-shaped steel, etc. Hot rolled steel for construction in China mainly uses carbon structural steel Q235-A (with a carbon content of 0.14-0.22%), which has moderate strength, good plasticity and weldability, low cost, and is suitable for use in construction projects. In the steel structure design specifications, there are two types of low alloy steel recommended for use: Q345 (16Mn) and Q390 (15MnV), which are used in large-span, dynamic load bearing steel structures.   (2) Cold formed thin-walled steel is usually formed by cold bending or molding of 2-6mm cypress steel plates, including open thin-walled steel such as angle steel and channel steel, as well as hollow thin-walled steel such as square and rectangular. Mainly used for lightweight steel structures. Its labeling method is the same as that of hot-rolled steel sec…
