The advantage of steel structure workshop:
Product Description:
The load bearing parts for steel structure workshop are mainly steel structures, including steel columns, steel beams, steel structural basements, bracing systems for wall and roof. Steel workshops are divided into Light Steel Workshops and Heavy Steel Workshops. The Main Structure are usually made of Q345 Steel while the Purlins and Bracing System are made of Q235 Steel. They are the most common steel materials used for steel structure in China.
