In recent years, steel structures have become a popular building material.Most factories are built with steel structures.Why do businesses use steel structures? Let's see.1. The steel structure is light in weight: Although the steel structure is heavy in weight, its strength is much higher than other building materials.Therefore, under the same loads and conditions, steel structures are lighter than other structures and are easier to transport.And can span larger spans.2. Steel has good plasticity and toughness, so due to accidental overloading or partial overloading, steel structures usually do not break and break.Good toughness makes the steel structure more adaptable to dynamic loads.These properties of steel provide sufficient guarantee for the safety and reliability of steel structures.3. Steel is closer to the internal structure of homogeneous and isotropic steel, very close to homogeneous and isotropic objects, and is almost completely elastic within a certain stress range.These properties conform to the assumptions in the mechanical calculations, so the calculated results of the steel structure are more in line with the actual stress conditions.4. The steel structure is easy to manufacture, easy for industrial production, and the construction and installation period is short.The steel structure consists of various profiles and is easy to manufacture.A large number of steel structures are fabricated in specialized metal structure manufacturers; with high precision.The finished product is assembled to on-site assembly, bolted, light structure, convenient construction and short construction period.In addition, the finished steel structure is also easy to disassemble, reinforce or modify.5. Good sealing steel structure has good air tightness and water tightness.6. Steel structure has good heat resistance, but poor fire resistance and good weather resistance of steel.hot.With increasing temperature and decreasing strength.When there is radiant heat around, when the temperature is higher than 150 degrees, shielding measures should be taken.If the fire reaches a temperature of 500 degrees or higher, it may collapse immediately.In order to improve the fire resistance of the steel structure, it is usually wrapped with concrete or bricks.
