What is the difference between angle iron and angle iron

Issuing time: 2018-12-11 14:23:26


We already know about angle iron, angle iron and other issues. So what is the difference between angle iron (chǐ cùn) angle iron and angle iron? It is estimated that many people are not yet familiar with it. Today we will familiarize ourselves with experts (zhuānjiā)!
Specification of angle iron

It is mainly divided into two types: equilateral angle iron and unequal angle iron. Among them, unequal angle iron can be divided into two types: unequal thickness and unequal thickness.

Angle iron specifications (specifications) are expressed in terms of side length and side thickness (chǐ cùn). 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. At present, the specifications of domestic angle irons are 2-20, and the number of centimeters of sides is the number. The same angle iron often has 2-7 different side thicknesses. The imported angle iron indicates the actual size and thickness of the two sides and the relevant standards. Generally, those with a side length of 12.5cm or more are large angle irons, those between 12.5cm and 5cm are medium-sized angle irons, and those with a side length of 5cm or less are small angle irons.

The ordering of angle iron for import and export is generally based on the specifications required in use, and the steel number is the corresponding carbon steel number. Shenzhen steel plate wholesale is a flat steel made by pouring molten steel and pressing it after cooling. Steel plates are divided according to thickness, thin steel plates <4 mm (0.2 mm thinnest), thick steel plates 4 to 60 mm, and extra thick steel plates 60 to 115 mm. Steel plates are divided into hot rolled and cold rolled according to rolling. The steel plate is flat and rectangular, which can be directly rolled or cut from a wide steel strip. The steel type of the thick steel plate is substantially the same as that of the thin steel plate. In all aspects of the product, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high pressure vessel steel plates and other varieties are purely thick plates, some types of steel plates such as automobile beam steel plates (2.5 to 10 mm thick), patterns Steel plates (2.5-8 mm thick), stainless steel plates, and heat-resistant steel plates are intersected with thin plates. 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. It is also that the angle iron has no specific composition and performance (xìng néng) series except the specification number.

The delivery length of the angle iron is divided into two types: fixed length and double length. The selection range of domestic angle irons is 3-9 according to the different specifications.
M, 4-12
M, 4-19
M, 6-19m four ranges (fàn wéi). The length selection (xuanze) of Japanese-made angle iron is 6-15m.

The section height of the unequal angle iron is calculated by the long side width of the unequal angle iron. Refers to the steel (Steel) material whose cross section is angular and the lengths of the two sides are not equal. It is one of the angle irons. Its side length is 25mm × 16mm · 200mm × l25mm. Rolled by a hot rolling mill. General unequal-angle iron specifications (∟50 * 32--∟200 * 125, thickness is 4-18mm)

Unequal angle iron is generally applied to various metal structures, bridges, machinery manufacturing (zhì zào) and shipbuilding industry, various building structures and engineering structures. Beams, bridges, transmission towers, lifting and transport machinery, ships (interpretation: general name of ships), industrial furnaces, reaction towers, container racks and warehouses.

Angle iron is commonly known as angle iron, which is a long steel bar with two sides forming an angle perpendicular to each other. Shenzhen I-beam wholesale, also called steel beam (English name Universal Beam), is a long strip of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is an I-shaped steel with a cross-sectional shape. I-beams are mainly divided into ordinary I-beams, light I-beams and wide flange I-beams. According to the height ratio of flange to web, it is divided into wide, medium and narrow wide flange I-beams. The specifications produced by the former two are 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, lightweight I-steel has narrow flanges, thin webs, and light weight. The wide flange I-beam is also called H-beam. The cross section is characterized by two legs parallel and no slope inside the legs. It is an economical section steel, which is rolled on a four-high universal rolling mill, so it is also called "universal I-beam". Ordinary I-beams and light I-beams have formed national standards. There are equilateral angle iron and unequal angle iron. Both sides of an equilateral angle iron have the same width. Its specifications are expressed in millimeters of edge width × edge width × thickness. For example, “∠30 × 30 × 3” means equal-angle iron 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 size of different side thicknesses in the same model. Therefore, the side width and side thickness dimensions of the angle iron are completely filled in documents such as contract, and it is avoided to use the model number alone. The specifications of hot-rolled equilateral angle iron are 2 # -20 #.
