I-beam, also called steel beam, is a long strip of steel with an I-shaped cross section. I-beam is widely used in various building structures, bridges, vehicles, supports, machinery, etc.

12 # I-beam specifications

1. I-beam is expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as "I 160 * 88 * 6".
2. The specifications of I-beam can also be expressed by the model, which indicates the number of centimeters of waist height, such as 工 16 #. For I-steel with the same waist height, if there are several different leg widths and waist thicknesses, add abc to the right of the model to distinguish them, such as 32a # 32b # 32c # and so on. I-beams are divided into ordinary I-beams and light I-beams. The specifications of hot-rolled ordinary I-beams are 10-63 #.

Scraper steel is mainly used in scraper conveyors and transferers.
Scraper steel classification: Because the profile is a type of steel, there is also a different content of P, and a type of scraper steel profile, so it is also divided into:
(1) Ordinary scraper steel (P≤0.045%, S≤0.050%)
(2) High quality scraper steel (P and S are both ≤0.035%)
(3) High quality scraper steel (P≤0.035%, S≤0.030%)

π型钢

π-shaped steel is mainly used to make π-shaped beams, metal roof beams, articulated roof beams and other mining support steel beams. It plays a supporting role in mines (mines) tunnels (lanes) because its cross-section is similar to the letter " "π". The π-shaped steel structure is composed of one surface and two legs, and both sides of the surface have jagged lace.

Product Features

π-shaped steel can be combined with various types of monomers and metal pillars to form metal supports for coal mines to be used in horizontal and slow inclined mining face and head or other large top-control areas. It can long-span cantilevered support and control the roof of the roof area, realizing a large working space without pillar support on the working surface, and has improved favorable conditions for the improvement of labor conditions and the use of new coal mining machinery and flexible conveyor cashiers.

轻轨

The "light" of the light rail refers to the light load, not the light axle weight and rail weight. In fact, it has nothing to do with the axle weight and rail weight at all.

Rails with a nominal weight of more than 30 kilograms per meter are heavy rails. Heavy rails are divided into general steel rails and crane rails. General steel rails refer to the laying of railway trunk lines, special lines, curves and tunnels. Among them, there are two types of standard rails, 12.50 meters and 25.00 meters in length. Curved curved tracks are laid with shorter lengths, such as 12.46 meters, 12.42 meters, 24.96 meters, 24.92 meters. , 60 (kg / m).
The heavy rail has a larger cross section than the light rail and can withstand greater forces. The early main railways, as well as those using 38 kg of rails, now use 50 kg and 60 kg.

Channel steel is a long strip of steel with a grooved cross section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40 #. The specifications of the hot-rolled channel steel supplied through the agreement between the supply and demand parties are 6.5-30 #.
Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures. Channel steel is often used in conjunction with I-beams.

U型钢

U-shaped steel is also called mine support steel. It is mainly used to make U-shaped steel supports or arched steel sheds, which are used to support mines and roadways.
U-shaped steel can be divided into: 25U steel, 29U steel, 36U steel

H型钢

H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sections, which greatly meets engineering design and production requirements. Wide flange, large lateral rigidity, and strong bending resistance. Easy processing and installation. Compared with welding I-beams, it has low cost, high accuracy, and small residual stress. It does not require expensive welding materials and weld seam detection, which saves about 30% of the cost of steel structure production.

Advantages of H-beam

H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sections, which greatly meets engineering design and production requirements. Wide flange, large lateral stiffness, and strong bending resistance. The two surfaces of the flange are parallel to each other to make the connection, Easy to process and install. Compared with welded I-beams, it has low cost, high accuracy, and small residual stress. It does not require expensive welding materials and weld seam detection, saving about 30% of the cost of steel structure production under the same cross-section load. The hot rolled H steel structure is 15% -20% lighter than the traditional Tong structure. Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, and the structure's own weight is reduced by 20% -30%, which reduces the internal force of the structural design.
