Companys production

The industrial complex of the company SteelProfileInvest, LLC is located in Tula region at

Bolokhovskaya engineering plant. Rolled steel with polymer coating is one of our main products.

For metal painting we use an innovative method of coil coating. In this process, metal sheets meet

special treatment and then paint is applied by roller machines. We use only high quality enamels

produced by leading companies.

Steel painting process is divided into two stages:

arrow Surface preparation before painting.


     arrow double degreasing of sheet surface;

     arrow passivation of steel sheet surface with special chrome solution.


arrow Painting of steel sheet


     arrow priming by rolling method (goal: achieving adhesion);
     arrowdrying of the primer layer in the drying ovens, according to zones, with given temperature;

     arrow enamel applying by roller coating method;
     arrow enamel drying in drying ovens, according to zones, with given temperature; 
     arrow coiling painted sheet into coil.


Structure of painted steel sheet has a complex structure and is produced by several stages:


    arrow Basic protection against corrosion processes is a zinc layer. 

    arrow In the passivation stage zinc became coated with oxide film for protection against corrosion.

    arrow Primer coating improves the adhesion of the base layer and the polymer protector.

    arrow As a finishing coating for the front side of the sheet uses a polymer coating. Polymer coating

       is protected during storage and transport with self-adhesive film.
