Metal corner

DESCRIPTION

The corner in its use is one of the leading positions in the use of rolled metal. The corner is a metal product and is made from various grades of carbon steel. Also, the steel corner can be made of high-strength low-alloy steel.

Equal angle
Steel corners are divided according to the type of section, into equal and unequal. the width of the corner flange can vary, mainly from 20 to 200 mm with different metal thicknesses up to 16 mm, the length of the corner from 4 to 12 m. Steel angle can be produced in two ways, hot-rolled metal or by bending cold-rolled or hot-rolled metal sheet.

Unequal corner
The hot-rolled type of production of a corner consists in rolling an ingot (bloom) through rotating shafts, under pressure and rolling, the billet is formed to the required size and passed through a rolling mill, so a hot-rolled steel corner is obtained. Twisting of the corner along the axis is not allowed, the permissible coefficient of curvature of the corner is not more than 0.4% of the length, and the maximum deviations along the length of the corners are not more than 0.75% of the length of the corner. The bent corner is obtained on roll forming machines.
Steel angles are distinguished by accuracy class, class A - high accuracy and B - medium or normal accuracy. So, when classifying a corner, it is important to know the metal (grade of rolled metal), the manufacturing method, accuracy and length of the corner. Hot-rolled corner is used in construction, in the production of cars and other equipment. The use of the corner is very diverse.
