Hot rolled steel sheet. Expanded steel sheet (PV)

LLP "Metalservice Kazakhstan" We have been working in the market of Kazakhstan for more than 5 years. Our main goal is to timely provide the end user with high-quality rolled metal products. The products offered by us are widely used in mechanical engineering, as well as in the oil, petrochemical, gas industry, thermal power engineering, construction, the defense complex, agriculture, and the food industry. 1. Wire rod. Masonry mesh. Hot-rolled sheet, cold-rolled sheet, corrugated sheet According to the production method, rolled steel sheet is divided into hot and cold forming products. Hot-rolled steel sheet is made on rolling mills by heating the original billet and driving it through several stands with flat rolls. The next rolls have a smaller gap compared to the previous ones, so the steel sheet gradually acquires the desired thickness. Classification of hot-rolled steel sheet According to the thickness of the resulting steel products, thin-sheet (0.4-3.9 mm) and thick-sheet (4.0-160.0 mm) steel are distinguished. Sheet steel can be used as a final product or as a blank for the production of various products. So hot-rolled steel sheet is often used for the manufacture of shaped steel in the form of a corner, a channel, an I-beam. Hot-rolled metal has a width of 500 mm and is produced in sheets with a thickness of 0.4 to 160 mm and in coils with a thickness of 1.2 to 12 mm. According to the rolling accuracy, a hot-rolled sheet with a thickness of up to 12 mm is divided into products of increased accuracy (A) and normal accuracy (B). Hot-rolled products differ in flatness: PO, PV, PU, PN. For the arrangement of platforms, galleries, decking, transitional bridges, steps of mid-flight stairs in industrial buildings and structures, expanded steel sheets are used. Compared to solid sheet metal, expanded metal sheet GOST 8706-78 has a number of advantages, the main of which is much lower weight while maintaining performance characteristics. Features of the production of expanded steel sheets Expanded-drawn sheet is cut and drawn from hot-rolled steel sheet with a thickness of 4 to 6 mm, cold-rolled sheet steel with a thickness of 1.5 to 2 mm and galvanized sheet steel with a thickness of 0.7 to 0.8 mm , according to the regulation GOST 8706-78 or specifications TU 36.26.11-5-8. After the process of punching in the web of the steel sheet of cells, due to which a significant weight reduction is achieved, the steel sheets are subjected to additional rolling through the drawing rollers in order to flatten them and increase the rigidity index. In addition to its light weight, expanded steel sheet has a high ability to prevent slipping, which greatly increases its use for organizing flooring in
