         China's steel consumption has obvious characteristics of the developing countries, and industrial construction steel consumption accounted for about 90% of the total consumption of steel construction steel in which the proportion is 50%. Because China is in the historical period of rapid development of urbanization, high demand for construction steel. Steel as the main construction steel consumption has been dominated by a large proportion of China's steel production.




 

Angle's classification

         Commonly known as angle iron angle, perpendicular to each other on both sides of a triangle strip steel.
         There equilateral angle and unequal angle of the points. Equilateral angle of two wide sides are equal.
Its specifications expressed in edge width × edge width × millimeters thick edge. Such as "∠30 × 30 × 3", it means that the edge width of 30 mm, edge thickness of 3 mm equilateral angle. Also available models indicated that the model is a few centimeters wide edge, such as ∠3 #.
Models do not represent different sides of the same thickness of size models, contracts and other documents will thus angle of edge width, edge thickness dimension fill is complete, avoid using separate models representation. Hot-rolled equilateral angle specifications for the 2 # -20 #.
         Angle may require different structure composed of various members of the force, but also for connections between components. Widely used in various building structures and engineering structures such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse.

 


 

Angle Introduction

         Angle may require different structure composed of various members of the force, but also for connections between components. Widely used in various building structures and engineering structures such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame, cable channel bracket, power piping, busbar support installation, as well as warehouse shelves.
         Angle the case with the construction of carbon steel, the steel is simple section steel, mainly used for metal frame member and factories and so on. In use requires good weldability, and the plastic deformation of a certain mechanical strength. Angle steel billet production of raw materials for the low-carbon square billet, hot-rolled steel angle finished forming, normalizing or hot-rolled state delivery.

Category Specification

         Mainly divided into equilateral angle and unequal angle into two categories, which can be divided into unequal angle ranging from thick and thick scalene equilateral two unequal.
         Angle specifications represented by the sides and edge thickness dimensions. Current domestic angle specifications for 2-20, a few centimeters side to the number of number, the same number of different angles often 2-7 edge thickness. Imported angle marked on both sides of the actual size and edge thickness and indicate the relevant standards. General side length 12.5cm above for large angle, 12.5cm-5cm for the medium angle between the side length of 5cm or less for small angles.

Specifications

        Angle GB / T2101-89 (General Provisions steel acceptance, packaging, marking and quality certificate); GB9787-88 / GB9788-88 (hot-rolled edge / unequal angle size, shape, weight and tolerances); JISG3192 -94 (hot-rolled steel shape, size, weight and Tolerance); DIN17100-80 (general structural steel quality standards); ГОСТ535-88 (ordinary carbon steel technical conditions).
        
According to the provisions of the standard, angle should be a bundle of delivery, the strapping passes, with the bundle length should be specified. Angle is generally within the bare delivery, transport and storage require attention to moisture.
        
Importers angle of orders generally required specifications in use mainly as its corresponding carbon steel structural steel steel. It is the angle in addition to specification number, no specific composition and performance series.
        
Angle delivery length is divided into fixed length, two double length, made of angle iron cut to length range of options, depending on size numbers have 3-9m, 4-12m, 4-19m, 6-19m four ranges. Select the length of angle iron in Japan range from 6-15m.
        
Equilateral angle steel unequal angle section height by width to calculate the long side. It refers to the angular cross section and long sides of unequal steel. It is the angle in one. By the side length 25mm × 16mm ~ 200mm × l25mm. Rolling the hot rolling mill from. General equilateral angle specifications: ∠50 * 32 - ∠200 * 125 thickness 4-18mm
        
Equilateral angle steel is widely used in a variety of metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
