Examples of product application

Anti-corrosion coating/material:

Types of coatings/materials:

Anti-corrosion coatings used in the production of our products are the highest quality protection against corrosion of surfaces and installation components that work in environments that require increased resistance to chemical environment, UV and water, ensuring high performance quality parameters.

Galvanized

This is the most common way to protect the surface of metal. Metal components protected with galvanized zinc plating are designed for indoor installation.

Stainless steel

The exceptional corrosion resistance of stainless steel is due to the passivation process of the material. The oxide layer produced, despite its very small thickness, provides resistance to the penetration of corrosive agents and determines the resistance to corrosive environments.

Ultra Cover XP coating

Our latest development is Ultra Cover XP, an ultra-thin anti-corrosion coating that protects products, leaving behind previous galvanizing and hot-dip galvanizing technologies. Ultra Cover XP is a group of advanced lamellar, zinc-nickel and thick-coat passivation coatings, making it very high resistance to external influences.

Main advantages and benefits
  • • superb corrosion resistance
  • • high resistance to temperature and chemical agents
  • •resistance to many mild chemicals and solvents, including gasoline and brake fluid
  • • no occurrence of hydrogen embrittlement in the material
  • •ability to cover complex shapes, recesses and holes
  • • ability to cover complex shapes, recesses and holes
  • • the small thickness of the Ultra Cover XP coating has greater corrosion resistance than the large thicknesses of traditional coatings

The Ultra Cover XP coating consists of several layers. Initially, the product is coated with a base layer that reacts with the surface of the steel, forming, after appropriate processing, a kind of tightly adherent shell. The base is then coated with sealant, which gives the whole the required durability. Ultra Cover XP makes the product more repeatable, durable and weatherproof.

Ultra Cover XP coating is eco!
<p>Ultra Cover XP contains no harmful chromates, is safe for the environment and energy-efficient and low-impact to produce. The coating process offers less energy use and low water consumption than other similar processes.</p>

Hot-dip galvanizing

The thickness of zinc coating is from 45 to 150 microns. Hot-dip galvanization is an exceptional protection against corrosion and im- pact of atmospheric conditions. Hot-dip galvanized products are intended for application, most of all, outside, where they are in contact with atmospheric conditions.
