Structural features a box room, with a steel structure, light weight, easy installation, short construction period, seismic performance, fast return on investment, environmental pollution and less comprehensive advantages, good ductility and toughness, good impact resistance. 2, the type of steel are: different sub-sheet thickness (steel sheet thickness <4mm), plate (thickness 4-20mm) and slab (thickness 20--60mm) more than 60 kinds of special thick. Steel strip included in the class. 3, the difference between the ordinary high-strength bolts and bolts? Ordinary bolts generally used ordinary carbon steel, without heat treatment, high strength bolts quality carbon structural steel or alloy structural steel for general use, you need to go through transfer of heat treatment to improve the overall mechanical properties. High intensity divided, 8.8, 10.9, 12.9. From the intensity level: high-strength bolts used 8.8S and 10.9S two intensity levels. Ordinary bolt generally have 4.4, 4.8 5.6 8.8. Features from the force applied to the pre-tension and high-strength bolts passing by friction force containers, general rod bolt by bolt hole wall shear force and shear pressure to deliver.
