- The right material for every environment
The material used in most of our products is hot-dip galvanized steel sheet in various thicknesses, coatings, and colours.
The properties of the material are adapted depending on where it will be used.
A softer grade is recommended when the sheet will be formed, for example in standing seam roofing. For manufacturing ridge caps or bargeboards, however, the sheet should have a harder grade. In most environments, hot-dip galvanized steel sheet performs excellently. If the building is located in an area with salty and humid air, a coated aluminium sheet is a better choice.
By treating the base material with several layers, we achieve performance that withstands all conceivable environmental stresses and quality requirements.
Steel Sheet
Most sheets from ArcelorMittal Projekt have a core of high-quality steel. The steel grade and thickness are chosen based on the desired properties.
Steel sheet construction
Closest to the core is a modern corrosion protection layer consisting of a mix of zinc, aluminum and magnesium.
The corrosion protection is followed by a passivation layer , a primer layer and finally a top layer in one of our proprietary coatings. The coating determines the appearance of the sheet but also its resistance to scratches and wear.
The construction of the back of the sheet has a similar structure with corrosion protection, primer and a slightly thinner back paint.
AMM and AMS
AMM and AMS give names to a new generation of flat and strip roofing sheets manufactured by ArcelorMittal.
The materials have a thicker top layer than other coatings and guarantee increased wear resistance and better resistance to weathering.
All AMM and AMS products come with a 20-year warranty.
Aluminium
Aluminium is an excellent alternative in environments with salty and humid air. The structure of an aluminium roof is similar to that of a steel sheet roof.
Aluminum construction
The difference lies in the layer closest to the core where aluminum does not require the same corrosion protection.
