The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust prevention processes.

Welds, bolts or rivets are usually used between the components or components, because of its light weight and easy construction, it is widely used in large factories, venues, super high-rise, Bridges and other fields.

Steel structure has the following advantages:

Steel strength is high, elastic modulus is also high, compared with concrete and wood, its density and yield strength ratio is relatively low, so under the same stress conditions of steel structure members small section, light weight, easy to transport and install, suitable for large span, high height, heavy bearing structure.

Steel toughness, good plasticity, uniform material, high structural reliability, suitable for bearing impact and dynamic loads, with good seismic performance.

Steel structure manufacturing is simple, easy to use industrial production, short construction and installation cycle, steel structure is composed of various profiles, simple production, a large number of steel structures are manufactured in specialized metal structure manufacturers, high accuracy, in addition, the steel structure has been built is also easy to disassemble, reinforce or transform.

The sealing performance of the steel structure is good, and its air tightness and water tightness are better.

The heat resistance of the steel structure is good, but the fire resistance is poor, the steel is heat resistant and not resistant to high temperature, and the strength decreases with the increase of temperature.
