A wide variety of fields of activity are not complete without this type of metal-roll - the manufacture of metal structures, construction, finishing works, mechanical engineering and even furniture production. Metal corner (the price depends on the method and material of manufacture) is in high demand and despite for the simplicity of its geometry, it has a huge form of names that correspond to the current GOST parameters, as well as the individual (specific) requirements of customers. We will tell you in more detail what criteria are used to select the required corner.
Manufacturing method and dimensions
A metal corner refers to the type of rolled metal, for the manufacture of which carbon, alloyed or design steel grades, as well as non-ferrous (mainly aluminum) metal alloys, are used. There are three ways to produce it:
- Hot rolled - allows the production of products with a high profile thickness from extra strong types of steels.
- Cold rolling - carried out without preliminary heating on special mills.
- Bending is the simplest option, it can even be done manually. Corresponding bending equipment is used on an industrial scale.
The manufacturing method is indicated in the technical documentation using the appropriate letter designation or directly on the product itself (corner).
The dimension of the corner is determined by the parameters of the thickness of the profile from which it is made and the width of the shelf (folded parts for equal-shelf) or each shelf separately (for multi-shelf) products. In the designation of the corner there is a characteristic of the accuracy class (compliance with the GOST parameters), "A" - high (size deviations no more than 0.4%) and "B" - standard.
You can get a more complete picture of the existing classification of metal corners using the official Internet resource of the STO TONN company in Minsk, which supplies this type of rolled metal to the market. The products presented in the catalog fully comply with the established (declared) parameters of quality and reliability.
