Angle iron is becoming more and more important in building structures and engineering structures to fulfill our daily life. There are so many angle iron suppliers in China and the angle iron prices are competitive. Among them, Steel from China guarantees great quality and reasonable prices.
Angle iron is mainly used to make the frame structure, such as high-voltage transmission tower, steel bridge frame on both sides of the tower, crane on the construction site of the column and arm, workshops columns and beams, some small places like the roadside flowerpot shape shelf, hanging shelf solar air conditioning in windows. Angle of the surface quality requirements in the standard, general requirements may not exist in the use of harmful defects such as delamination, scarring, and cracks. Angle iron geometry of the allowable range in the standard deviation is also provided, generally comprises a curved edge, width edge, other items of the theoretical weight and the predetermined angle of twist can not be significant.
The manufacturing process of angle iron is relatively simple, and according to the production technique angle iron can be divided into two types which are hot-rolled and cold-formed. Hot rolled steel angle is large, while cold-formed is relatively smaller. Standard process is billet through a dedicated many channels repeatedly rolling steel mills gradually rolled into v shape. There is a transition in the inner corner of the arc with reliable mechanical properties. Rather small workshop production is directly rolled sheet or strip with a curve into the inside corner no transition arc, and because the larger the bending stress in a corner, and poor mechanical properties, the most important point is that the material is not guaranteed, this generally can not buy back angle bend, nor welding, drilling up to take the length. Angle steel billets for the production of raw material for carbon square steel billets, hot rolled angles finished forming, hot-rolled or normalizing the status of delivery.
