Why choose color coated steel for buildings?

The use of color coated steel for building applications, as opposed to other materials, allows for great opportunities to create beautiful and functional buildings that meet high environmental and quality requirements.

As our society moves towards a more environmentally sustainable future, color coated steels can play a part in new building solutions. GreenCoat® products offer freedom for architects and designers. A large variety of shapes, colors and surface appearances combined with environmentally sustainable products make GreenCoat® an attractive choice. GreenCoat® color coated steel is a perfect material for buildings whether it is a modern arena, a traditional cultural building, a residential home or a warehouse storage.

Color coated steel has the benefit of being a combination of lightweight and high strength. On top of this, the material is extremely durable. These properties contribute to short construction times and easy handling on the construction site. The material is the perfect choice for renovation and extensions. The consistent and high quality of the GreenCoat® products makes them highly suitable for industrial processing. Our extra formable steel grades are easy to form by hand and can be used in sophisticated forming operations even down to -15 °C without damage to the color coating or steel.

Buildings made from GreenCoat® steel provide safe and sustainable climate protection with very low maintenance costs. GreenCoat® products will protect your building for many decades and at the end of its lifetime, the steel can be re-melted and processed into new steel products. Steel is 100 % recyclable without any loss of quality. Both from an environmental and economical view – steel is the sustainable solution.

Color coated steel – corrosion protected and long lasting appearance

The base material in color coated steel consists of steel, coated with a thin zinc layer. The steel is chosen with properties that will best suit the end product. For structural steel applications this follows standardized mechanical properties according to EN 10346. For applications where the steel should be formable in a demanding way or the product should be worked with by tinsmiths, extra formable steels are used.

The zinc coating protects the steel from corrosion in two ways. It is a protective layer keeping oxygen and water away from the steel, but it also acts as a cathodic protection. This means that at cut edges or in case of damages through the zinc coating, the zinc will sacrifice itself and react to form protective compounds andblock further corrosion processes.

The zinc coating is measured in weights per square meter and covers the steels on both sides.

The pre-treatment layer is applied to further improve the corrosion resistance, but also to give a good adhesion to the coating layer.

The primer layer is used for corrosion protection with corrosion protective additives and also acts to give a good adhesion to the top coat.

The top coat type is chosen to best fit the purpose of the application. It can be chosen to serve in different environments and also offer different appearances. This is also the layer that gives the final product its color.

A two layer backing coat protects the reverse side of the color coated steels. In this layer our GreenCoat® products are marked with a text that identifies GreenCoat® and SSAB as the original manufacturer.
