For the production of a certain type of metal parts or structural elements, flat dimensional sheets are used as blanks. They are produced according to GOST parameters at metallurgical enterprises. Standard sheet metal is manufactured using proven cold or hot technologies (the workpiece is preheated to a plastic state) deformation on special high-tech pressing (rolling) equipment.
Classification and types of rolled sheets
Classification of rolled sheets is carried out according to dimensional parameters, taking into account the type of technology used for its production:
- Hot rolled - thin with thickness from 1.2 to 4 mm and thick from 4 to 160 and sheet width 500-4500 mm.
- Cold rolled - thickness 0.25-5 mm, width 500-2350 mm.
Varies in dimensional accuracy - normal and increased. Finished products can undergo additional heat treatment - hardening, annealing. Production data and characteristics are indicated by the manufacturer in the technical data sheet for each batch of products.
Material of manufacture
Sheets are made from various grades of steel and alloys - black, carbon, alloyed and tool. The grade is indicated in the abbreviation of the rolled sheet product range. Compliance of the chemical composition is confirmed by a certificate.
Surface coating
The surface of rolled sheets can undergo additional processing - painting, priming, galvanizing. Allows you to improve technical characteristics and corrosion resistance.
Product sales
Rolled sheets are sold by large suppliers. Warehousing and sorting are carried out in metal depots equipped with the necessary equipment. Calculation of the selling price of the desired item will be carried out using the formula “per 1 ton of product”. You can select the desired type and required volume using the online catalog of the supplier’s official website. Payment is accepted in any way convenient for the customer. Original payment documentation and certificates are issued upon request.
