Shanghai Sur-Union Construction focuses on EPC construction, steel structure engineering and low-rise prefabricated house buildings. It owns 2 fabrication bases and has a complete production system and non-standard metal structural parts production system, including space grid, space truss, light & heavy steel structure, purlin, structural accessories (such as edge trim, support, gutter and downpipe). Over 20,000 tons of steel structure products are fabricated every year. Shanghai Sur-Union Construction also provides serialized and personalized processing services for customers.
Shanghai Sur-Union Construction ‘s excellent management team has successfully completed over 1,000 projects and accumulated rich management experience. Our reasonable price confirming to international practice won unanimous praise from customers at home and abroad.
Shanghai Sur-Union mainly provides customers with design, fabrication, erection and after-sale service for EPC construction, steel structure engineering and low-rise prefabricated house buildings. The company has first-level general contracting of building engineering construction, first-level professional contracting of steel structure projects, and second-level special qualifications for foundation and foundation engineering.
Prefabricated building refers to the transfer of a large amount of on-site work in the traditional construction method to the factory. Through large-scale production, the building components and accessories (such as floor slabs, wall panels, stairs, balconies) are processed in the factory and transported to construction site, rapid assembly and dry construction are carried out on site. This type of product is suitable for buildings with 3 floors and below such as villas, affordable housing and tourist resort hotels.
Space grid is a spatial structure formed by connecting multiple rods with joints in a certain grid form. These basic elements can be combined into a plane shape of a triangle, a quadrilateral, a hexagon, a circle or any other shape. From the shape, the grid can be divided into flat grid, curved grid (spherical shell, cylindrical shell) and various special-shaped grid.
Space truss refers to a lattice structure composed of rods connected to each other at the ends. The tube truss refers to that the rods in the structure are all round rods. Nowadays, it is widely used in convention and exhibition centers, stadiums and other large public buildings.
Light steel structure is a light-weight steel structure building system, which is mainly made of high-performance structural steel and high-efficiency functional materials such as hot-rolled light H steel, light welded steel, high-frequency welded steel, cold-formed thin-walled steel, assembled with various connection materials as supplements. It can meet the specific use function and specific space requirements of the building.
Membrane structure is also called tensioned membrane structure. Membrane structure is a new type of architectural structure developed in the mid-20th century. It is composed of a variety of high-strength thin-film materials and reinforcing members (steel frame, steel column or steel cable) to generate pre-tension stress to form a space shape. As a covering structure, it can bear a certain external load.
Cladding system mainly includes prefabricated cladding system for roof and wall and decking, metal sandwich panel, aluminum magnesium manganese plate roof and wall system.
Structural steel used in construction has the advantage of high strength, light weight, good overall rigidity and strong resistance to deformation. It is suitable for the construction of large-span, super-high and super-heavy buildings.
Cooperating with you sincerely, whether old friends or not.
