Angle steel price
Angle steel, commonly known as angle iron, is a long strip steel with two perpendicular sides. There are equilateral angle steel and unequal angle steel. The width of both sides of an equilateral angle steel is equal. Its specifications are expressed in millimeters of side width × side width × side thickness. For example, "∟30×30×3" refers to an equilateral angle steel with a side width of 30mm and a side thickness of 3mm. It can also be expressed by the model, which is the number of centimeters of the side width, for example, ∟3#. The model does not refer to the dimensions of different side thicknesses in the same model, so the side width and side thickness dimensions of angle steel should be completely filled in the contract and other documents to avoid using the model alone. The specification of hot-rolled equilateral angle steel is 2#-20#. Angle steel can be composed of various stressed components according to the different needs of the structure, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, warehouses and so on.
40*40 is divided into three sections, namely 40*40*3, 40*40*4, 40*40*5 and 40*40*3. A ton is 540m long, 40*40*4 is 4 13m, 40 * 40 * 5,337m.
Angle steel specification standard
GB/T 2 10 1-89 (general provisions on acceptance, packaging, marking and quality certificate of section steel); GB 9787-88/GB 9788-88 (Size, shape, weight and allowable deviation of hot-rolled equilateral/unequal angle steel); JISG3 192—94-94 (Shape, size, weight and allowable deviation of hot rolled steel); DIN 17 100-80 (quality standard for common structural steel); гост 535-88 (technical specification for ordinary carbon steel).
According to the provisions of the above standards, angle steel should be delivered in bundles, and its bundling pass and length should comply with the regulations. Angle steel is generally delivered naked, so attention should be paid to moisture prevention during transportation and storage.
Angle steel is the most commonly used stress component in our life. It is made of carbon structural steel with simple steel added to its cross section. The main function of angle steel is used in various building structures and engineering structures, such as lifting and transportation machinery industry, shipbuilding industry, industrial furnace industry, reaction tower industry, container shelf industry, cable trench support industry, power pipeline industry, bus support installation industry, warehouse shelf industry and so on. , and it varies according to different occasions.
