Modern building technologies, especially options for arranging the roof of residential and industrial buildings, widely use material such as corrugated board. Relatively inexpensive (depending on the type), practical for transportation, storage and installation, as well as durable rolled metal. For example, the most popular galvanized corrugated board has a 25-30 year manufacturer's warranty, regardless of the operating conditions.
Basic parameters
For the manufacture of galvanized corrugated board corresponding to the GOST parameters, according to the site https://stalintex.ru/catalog/profnastil-bez-pokrytiya/, only high-quality sheet steel should be used. As a rule, the ST 08PS brand is used, where:
- The CT symbol is steel.
- The abbreviation PS - semi-calm (a type of steel manufacturing technology).
For applying zinc coating, acid etching of the surface of the sheets is preliminarily carried out to remove scale. After additional rolling, they undergo a firing procedure, which gives the product higher strength parameters.
To apply a galvanized layer, prepared sheets are literally dipped into special baths with a molten coating. According to the existing GOST standards, zinc grades TsO, Ts2 and sometimes Ts2 are used for galvanizing. Sheets can have both one-sided and double-sided coating with a protective layer.
You can get more detailed information on the types and technical characteristics of galvanized profiled sheet using the official website of the supplier of this type of metal rolling to the domestic market. The online catalog of the resource contains products with precise markings that correspond to the existing GOST parameters, and a feedback service with a technical manager is provided for consultation.
