Prefabricated Components Structure components refer to assembly parts that are produced and processed to a certain extent in the factory, with an independent structural system, and can be directly transported to the construction site for installation. Common steel structure prefabricated components include steel beams, steel columns, steel bridge beams, steel structure floor slabs, etc. According to their application and form, they can be divided into frame prefabricated parts, plate prefabricated parts, steel pipe prefabricated parts, etc. The advantages of this structure include high strength, light weight, good overall stiffness, and strong resistance to deformation. It is particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings. After prefabrication in the factory, it can greatly save installation and welding work on the project site. Steel prefabricated components can be used for various types of mountain bridges, railway bridges, highway bridges, urban light rail bridges, substations, substations, ship structures, elevators, offshore platform structures, etc
Prefabricated Components Structure is a structure composed of steel materials and is one of the main building structure types.The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plate. welding, bolts or rivets are usually used between each component or component.
Because of its light weight and simple construction, it is widely used in industrial plants, municipal infrastructure construction, electric power, Bridges, offshore oil engineering, aerospace and other industries. Including bridge structure, plant roof beam column structure, bridge steel box girder(Steel Module), deck longitudinal beam, coal mine structure tower and so on.
Xinyue’s welding team has professional international welding capabilities, and has undertaken projects that meet various international welding standards, including ASME BPVC IX, AS/NZS 1554.1, AWS D1.1, D1.5, D1.6, D1.3, EN15164 and so on.
In order to solve the rust prevention on the surface of steel structure, we can also provide shot blasting and painting treatment on the surface of steel structure, including epoxy paint, galvanizing and other processes to extend the service life of steel structure and improve the service performance.
The main inspection methods of welding are: magnetic particle inspection(MT), penetration inspection(PT), UT testing , RT testing, etc.
