Why stainless steel as a basic material?

Because of our longtime experience with different materials we have come to produce all our color-coated objects only from high-quality stainless steel as a basic material. This is no low priced variant but it guarantees a long product life and many advantages that - in our opinion - multiply justify a higher price.

• In the case of scratches and signs of wear there is no risk of corrosion. Repair with the included color is easy and a rebuild of all layers is not necessary.
• In combination with stainless steel elements like water inlets, bolts, fittings etc. contact corrosion cannot be avoided if a different basic material is used. That is a risk which we can eliminate.
• The occurring crevice corrosion with steel sheets that overlap or that are slotted is always a challenge. The cracks have to be closed by seal welding which inevitably leads to warping due to heat. This problem is avoided by using color-coated stainless steel sheets.
• Stainless steel as basic material is much stabler as the soft and less expensive aluminum. If used for large areas aluminum is very vulnerable to bulges.
• In case of large-scale elements hot-dip galvanized steel is only partly suitable, because it often warps and forms bulges when zinc-coated. Furthermore the color-coating does not stick properly to the adhesive primer. In the worst case it flakes off the hot-dip galvanized surface after a few years

 

Layer Thickness of Color Coatings

The quality of the color coating system in combination with the layer thickness mainly determines the quality of the color coating and thus the durability and the resistance against corrosion.
The coating system we use consists of layers with primer respectively cover layer with color pigments with a thickness of about 35 to 40 µm. That procedure results in a layer thickness of 70 to 80 µm for our simplest forms of coating systems.
With the growing thickness the corrosion resistance increases. The same is true for the life span of the metal garden objects. If a layer thickness of more than 120 µm or more than 160 µm is needed, we can realize that, too, as an extra requirement.
If stainless steel is the basic material the layer thickness is irrelevant in relation to the corrosion resistance as it is already "rustfree". On stainless steel an adhesive primer is applied and then the cover layer with the color pigments. That is why it is then also possible to have a layer thickness under 50 um
