Coatings and colours

ALUZINC [AZ 185]

It is a steel sheet double-side coated with a zinc-aluminium alloy in a process similar to hot dip galvanizing. That way, it meets the most stringent requirements regarding the resistance of steel sheets against atmospheric corrosion and corrosion in humid environments. It comes with an additional, Easyfilm® protective polymer coating, which also protects the steel edges in coils and improves the aesthetics of the surface.

Warranty period: 25 years*

Aluzinc

GALVANISED SHEETS [ZN]

These sheets are hot dip galvanised on both sides in a continuous process to protect the steel core against corrosion. Their surface may have a specific “flower” shape (in two types) or come without it. The version without the “bloom” have a smooth and uniform surface meeting the highest requirements for appearance.

HERCULIT® [HC]

It is a coating developed in close cooperation with a leading manufacturer of varnishes for the best steel mills in Europe. Longterm research of the previously used coatings and monitoring of customer needs, with particular attention to the demands of the roofers, helped us to combine so many different advantages in one product. HERCULIT® is a polyurethane-hardened polyester, with great resistance to all kinds of mechanical damage, and a thickness of 35 μm. It also retains high colour repeatability to provide consistent coating colour and structure.

ICE COVER® ZM [ICep]

Thick (35 μm) organic foil with interesting texture resembling thick layer of paint. The core consists of a sheet covered with zing and magnesium alloy, which ensures better protection against corrosion. As a result, the material is more resistant to white and red corrosion in C3 environment. Guarantee period: 35 years.

Accessories

High-pass membrane
Roofing membranes are used as the base coating level beneath the inclined roofing. They prevent the wind from pushing rain and snow through to the thermal insulation and the roof construction. They protect from condensation forming under the base roofing. In addition, owing to their high vapour permeability, they keep the roof dry, which significantly decreases energy consumption.
Clamping systems
Since these accessories constitute the integral part of the roof covering, they must meet the highest requirements.
SHEET METAL WORKING
Ridge tiles and roof work are an inherent element of every properly executed roof covering. They provide protection against trickling and blowing and, simultaneously, they add an aesthetic value to the appearance of the roof.
STEEL GUTTER SYSTEM INGURI®
INGURI^® 125/87 AND 150/100 STEEL GUTTER SYSTEM

Application of a right gutter system allows for effective water discharge from roofing, which is vital for its durability and functionality. It also protects the building’s facade from damages caused by moisture.
Touch-up paints
Touch-up paints are used to protect cut edges and any possible damages to the surface coating when installing. In addition to the protective function, they help to maintain the aesthetics of the roof in top shape.
