Australia Standard Prefabricated Structural Steel Construction Railway Steel Structure

Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect components or parts. Because of its light weight and simple construction, it is widely used in large workshops, venues, super high-rises and other fields.

Features:

Steel structure has very good strength and strong toughness. For cement and wood, the value of density and elastic strength is not high, so under the same weight limit, the surface of steel structure construction is small, light weight, suitable for handling pavement, can be used for large span, high height, bearing capacity heavy structure.
The steel structure has good toughness and plasticity, the material is very average, and the construction is easy to use.
The steel structure is resistant to high temperature and fire. The properties of steel structures hardly change below 150°C. Therefore, the steel structure is more suitable for use in a high temperature environment, but when the surface temperature of the structure is about 150°C, the heat radiation on the structure surface should be protected by a heat shield. At 300°C-400°C, the strength and elastic modulus of the steel structure decrease significantly, reaching about 600°C, and the hardness of the steel structure is basically zero. For buildings with problematic fire protection requirements, the steel structure should be protected by fire-resistant materials to improve its fire-resistant performance.

Specification:

Application:
1. Industrial plant
In metallurgical workshops, open hearth, blooming workshop, converter workshop, iron mixing furnace workshop, steel casting workshop, forging workshop, hydraulic press workshop of heavy machinery factory, etc. In recent years, general industrial workshops have also begun to use steel structures.
2. Multi-storey and high-rise buildings
In the past, due to the shortage of steel, many projects still used reinforced concrete structure, but now steel structure is gradually developed in this field.
3. Large span structure
Aircraft hangars, aircraft assembly workshops, large halls, large coal depots, exhibition halls, gymnasiums, etc. require large-span structures, and their structural systems can be grids, suspension cables, arches, and frames.
4. Light steel structure
Lightweight portal steel structure houses and cold-formed thin-walled steel structures can be used for buildings with lighter loads or smaller spans. In recent years, lightweight structures have been widely used in industrial plants, offices, warehouses and sports facilities, and have been developed into residences and villas.
5. Plate and shell structure: oil depot, oil pipe, gas depot, blast furnace, hot blast stove, funnel, chimney, water tower and various pipes and other plate and shell structures.
6. Structures subject to vibration loads and seismic action
For a workshop with a forging hammer, the frame directly bears very little power, and the vibration of the workshop is very strong, so a steel structure can be used. Steel structures should also be used for those with high seismic requirements, and other special structures such as bridges, derricks, pipeline supports and offshore oil production platforms.
7. Detachable or removable structure
Production and living ancillary buildings on construction sites, temporary exhibition halls, etc., these structures are detachable, mobile structures such as tower cranes, crawler cranes, crawler crane jibs, gantry cranes, etc.
