Z-shaped steel sandalwood

Z-shaped steel sandalwood

Features of Z-shaped steel: In addition to its high strength, steel saving and other excellent properties, Z-shaped steel is particularly convenient and fast to install, and the material is Q195-345.

Steel Structure

Steel Structure

Large span structure. As the span of the structure increases, the proportion of the self-weight of the structure in the total load is also larger, and the reduction of the self-weight can obtain obvious economic benefits. For large-span structures, the advantages of light-weight steel structures are particularly prominent. The gymnasium in Shanghai, my country, which can accommodate 80,000 people, is an elliptical building with a spatial steel roof structure composed of radial cantilever lattices and circumferential trusses. The long axis is 288.4m, the short axis is 274.4m, and the maximum cantilever span of the roof is 73.5m. The Runyang Yangtze River Bridge was completed and opened to traffic in 2005. The main bridge in Nanhan is a single-hole double-hinged steel box girder suspension bridge with a main span of 1490m, which is currently the first in China and the third in the world.

Steel Structure

Steel Structure

Steel structures are used in various buildings and engineering structures, and there are many types. According to their connection methods, they can be divided into welded structures, bolted structures and riveted structures. Welded connection is the most important connection method for steel structures at present. Its advantages are simple structure, material saving, easy processing, and automatic operation. But welding can cause structural deformation and generate residual stress.

Steel Structure

Steel Structure

High strength and light weight. The strength of steel is high and the modulus of elasticity is also high, so the steel structural members are small and light. There are steels of various strength grades. Even the steels with lower strengths generally have a lower density-to-strength ratio than those of concrete and wood. Therefore, under the same stress conditions, the steel structure has a small self-weight and can be made into a larger span. Structure. Because the rod is small, it occupies less space, and is also convenient for transportation and installation.

Hot rolled H-beam

Hot rolled H-beam

Steels with various geometrical cross-sections rolled from heated billets. According to the different shape of the section steel, it is divided into three types: simple section, complex section or special-shaped section and periodic section.

Light (heavy) rail

Light (heavy) rail

The products cover steel components such as boxes, round pipes, H-shaped cross-shaped steel members, pipe trusses, Z/C-shaped purlins, and colored tiles. The company mainly undertakes the construction of steel structure high-rise buildings, portal steel frame workshop warehouse buildings, intelligent parking garages, overpass steel structures, gas stations, toll stations steel structures, and pipe truss steel structures.

Color steel plate

Color steel plate

Colored steel plate refers to the coating or pressing of organic paint or plastic film on the surface of galvanized sheet, cold-rolled sheet or aluminized sheet in a continuous production line to form a new type of metallurgical product.

Hot rolled equilateral angle steel

Hot rolled equilateral angle steel

The angle steel can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connection between the components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, hoisting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation and warehouse shelves Wait.

C-shaped steel sandalwood

C-shaped steel sandalwood

The characteristics of C-section steel: C-section steel is processed by cold bending of hot rolled plate, with thin wall and light weight, excellent section performance and high strength. The C-shaped steel rolled by the forming machine has a smooth surface and high dimensional accuracy, and the material is Q195-345.

Hot rolled I-beam

Hot rolled I-beam

Steels with various geometrical cross-sections rolled from heated billets. According to the different shape of the section steel, it is divided into three types: simple section, complex section or special-shaped section and periodic section.
