Surface treatment is a special treatment of materials by processing or application of another material layer by means of the chosen technology. Particularly, it is used to increase the resistance of the material surface against corrosion, abrasion, increased temperature, etc. Similarly, it improves mechanical, chemical, aesthetic and other properties of the surface.

In our centre of metal surface treatments, we execute blasting, and then the final treatment by wet painting or metallization; that is, zinc coating in the required thickness or Schoop plating.

Before the final product treatment, the required part surface must be cleaned by blasting, roughened or adapted in another way.

Blasting

The stationary blasting device used in our company (blasting box – blaster) is based on mechanical projection of abrasive particles with slinging wheels. The objects (products) blasted in the box are suspended on hooks of an electric hoist, which are rotating during the cycle, simultaneously moving horizontally before the slinging wheels. Pressure air is supplied to the blaster from the pressure chamber. The blaster air is filtered in an ecological filter with a fan. The abrading agent used is mostly recycled. The entire blasting process is automatic.

Technical data:

• maximum workpiece diameter: 2500 mm
• maximum workpiece height: 3500 mm
• maximum hook carrying capacity: 1600 kg

Painting

Wet painting (use of “wet” paints) is a standard as well as economically profitable way of final treatment of steel assembled structures and products for which a more universal utilization and aesthetic quality is required. The aesthetic value of the product increases its purchasebility.

Metallization

We keep at our disposal a workplace for execution of surface treatment metallization (so called Schoop plating) – by application of fused metal on the surface. Thanks to the modern technology of electric metallization, we are able to provide for high quality of the coat rendered (high adhesion and resistance of the paint) even at high output of the workplace with simultaneous low operating costs.

Moreover, we perform classical gas metallization, when a non-corroding metal is applied by spraying by means of acetylene flame and pressure air.

Maximum dimensions of the object (product) for metallization:

• 5.5.x 3.5.x.3.0 m – capacity of out metallization box
