To ensure the safety of the steel structure workshop should possess characteristics

1.good sealed performance
Since the welded structure can be completely sealed, airtight and watertight some of the requirements of a good high-pressure vessels, large oil tanks, gas tanks, piping and other steel plate and shell structures are used.

2.has a certain degree of heat resistance
Temperature within 250 ℃, the changing nature of the steel is small, the temperature reached above 300 ℃, the strength is gradually decreased, reaching 450 ℃ ~ 650 ℃, the intensity is reduced to zero. Therefore, the temperature is not higher than steel can be used in the case 250 ℃. There are special fire protection requirements in their own building, the steel must be maintained refractories.

3.poor corrosion resistance of steel
Steel's biggest drawback is easy to rust. New construction of steel structures generally need to be carefully rust, galvanized or paint brush. After a certain time interval, again, paint brush, high maintenance costs.

4.elastic, plastic, strong seismic performance
Under the same conditions bearing capacity, steel and reinforced concrete structures, wooden structure compared to smaller components, lightweight, easy to transport and install. Because of homogeneity and toughness of steel materials, may have large deformation, can well withstand dynamic loads, with good seismic capacity. Among them, the yield ratio is an important parameter to measure the ability of steel hardening. The lower the yield ratio, the ability of steel to resist strong earthquakes stronger. European construction steel requirements yield ratio is less than 0.91, while Japan requires construction steel yield ratio of less than 0.80. Meanwhile, the steel has good elastic, plastic and impact resistance, in general, the steel's ability to adapt to the dynamic load compared strong, its good ductility and energy dissipation capacity can ensure that it does not because of changes in the external load suddenly rupture, seismic steel which is very favorable.

In addition, the steel structure of these characteristics, not only can effectively reduce the project cost structure, but also making it a distinct advantage in dealing with special foundations and so on.
