The development of many industries in life (Develop) and angle steel are inseparable, sometimes some inconspicuous factors (maybe) may cause a large gap, such as the angle steel mentioned before, today we Let's find out (Do you know the difference between angle steel and angle iron model?). Shenzhen floor slab wholesale is
also called composite floor, floor slab or steel slab, Wancheng composite slab, profiled steel plate. Floor slab is an important supporting product for steel structure building, mainly divided into open floor slab, closed floor Plate, necked dovetail floor plate, reinforced truss floor plate. It is made of galvanized steel sheet through roll cold bending, and its cross-section is V-shaped, U-shaped, trapezoidal or similar waveforms. It is mainly used as a permanent template and can also be selected for other purposes. Another name for Shenzhen Fangtong Wholesale
Square Tube, which is the same length of steel pipe. It is made of rolled steel after processing. The strip steel is unpacked, flattened, crimped, welded to form a round pipe, and the round pipe is rolled into a square pipe and then cut to the required length. The small size on the market is usually 6 meters, and the large size is 12 meters. Other specifications can be produced according to the use conditions.
Angle steel (Steel) is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal edge thickness and unequal edge thickness.
The specifications of angle steel are expressed in terms of side length and thickness (chǐ cùn). Currently (Nowadays) domestic angle steel specifications are 2-20, the number of centimeters of the side length as the number, the same angle steel often has 2-7 different side thickness. The imported angle steel indicates the actual size and thickness of the two sides and indicates related standards. Generally, those with a side length of 12.5cm or more are large angle steels, those between 12.5cm and 5cm are medium-sized angle steels, and those with sides less than 5cm are small angle steels.
The ordering of import and export angle steel (Steel) is generally based on the specifications required in use, and its steel number is the corresponding carbon (C) junction steel steel number. Shenzhen H-beam wholesale
is the general name for steel used in the construction of beams or pillars in civil engineering, also known as I-shaped iron, which is named for its cross-section such as the Chinese character "工". Because the various parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used. That is, the angle steel has angles other than the specification number. The angle steel model has no specific composition and performance (xìng néng) series.
Angle steel (Steel), commonly known as angle iron, is a long strip of steel (Steel products) whose sides are perpendicular to each other. Shenzhen galvanized sheet wholesale
refers to a steel plate with a layer of zinc plating on its surface. Galvanizing is a commonly used economic and effective anti-corrosion method. About half of the world's zinc output is used for this process. Galvanized sheet can be divided into hot-dip galvanized steel sheet, alloyed galvanized steel sheet, electro-galvanized steel sheet, single-sided and double-difference galvanized steel sheet according to production and processing methods. The main importing countries include China, Japan, and Germany , Russia, France, South Korea, etc. There are two types of equilateral angle steel and unequal angle steel. The two sides of an equilateral angle are equal in width. Its specifications are expressed in millimeters of edge width × edge width × thickness. For example, “∠30 × 30 × 3” means equal-angle angle steel with a side width of 30 mm and a side thickness of 3 mm. It can also be expressed by the model, which is the number of centimeters of side width, such as ∠3 #. The model number does not indicate the dimensions of different side thicknesses in the same model, so the side width and side thickness dimensions of the angle steel should be filled in on the contract and other documents to avoid using the model number alone. The specifications of hot-rolled iso-angle angle steel are 2 # -20 #.
The above is a brief introduction about "Do you know the difference between angle steel and angle steel" (Introduction), our company also has angle steel, angle steel and many other related products (Product), If you are more interested, you can contact us for more details.
