Color-coated Stainless Steel

Brings Color to Your Garden

Farbe ist neben dem Spiel mit Formen und Materialien ein tolles Gestaltungsmittel, um Leben in den Garten zu bringen. Doch nicht nur mit gekonnt angelegten Beeten, die zu jeder Jahreszeit für ein üppiges Farbenspiel sorgen, können Sie Akzente im Garten setzen. Auch unsere hochwertigen Metallobjekte aus farbbeschichtetem Edelstahl wie Brunnen, Pflanzgefäße oder Sichtschutzwände sind ein tolles Stilmittel für einen individuellen Garten.

Farbpaletten nach DB-und RAL-Farbskala

Die meisten Gartenobjekte und Stadtmöbel aus unserem großen Sortiment fertigen wir für Sie in Ihrem Wunschfarbton. Dabei können Sie aus der ganzen DB-Farbpalette (Einschränkung: ohne Eisenglimmer) und den RAL-Farbtönen (ohne Farben mit Zusatz „Perl-„) auswählen.

Theoretisch ist jede Farbbeschichtung entweder in Glanz-, Struktur- oder Feinstruktur-Optik herstellbar. In der Praxis haben sich aber Strukturlacke in Feinstruktur matt aber am geeignetsten für den Außenbereich erwiesen. Diese Oberflächenstruktur hat den Vorteil, dass sie das Sonnenlicht bricht und die Objekte nicht spiegeln. Dazu kommt, dass alle großflächigen Gartenobjekte in der Fläche technisch nie perfekt sind. Die Strukturbeschichtung „verschluckt“ im Gegensatz zur Glanzbeschichtung geringe Unebenheiten.

Base material for color coating

For several years now, we have been manufacturing all of our color-coated garden objects from high-quality stainless steel V2A and not from „normal“ steel, aluminum or hot-dip galvanized steel. Although this is not the cheapest option, it guarantees a long service life and brings many advantages that, in our opinion, justify the higher price in several ways.

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 (see example).
  • Garden metal objects made from cheap steel sheets as basic material have – without maintenance and care – a product life of less than 10 years.

For the mentioned reasons Gartenmetall® has started using high-grade stainless steel as a basic material for color-coated metal garden objects, even if the tender offer dictates cheaper steel or aluminum.

Other advantages of stainless steel as a base material

  • If there are scratches in the paint coating, stainless steel objects will not corrode thanks to the high-quality base material. This makes the color-coated garden objects very durable and weather-resistant.
  • Contact corrosion usually occurs when stainless steel elements such as gargoyles, screws and fittings are combined with a „base material“ such as steel. This does not occur with the same base material.

Powder-coating or Varnishing?

Often we are asked for powder-coated objects. Instead of powder-coating we absolutely recommend a varnished surface, as scratches which might occur during installation or use can be easily recoated.

Coloring according to DB or RAL?

The DB-shade card is meant to show colors that were primarily used with the Deutsche Bahn (German railway). The colors contain the effect pigment engmicaceous iron ore in comparison to the colors of the RAL-color-system.

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 µm.

Suggestion for Tender Templates

“basic material stainless steel, material number 1.4301, AISI 304 (V2A) or of equal value, material properties according to DIN EN 10088 – 2. Surface of visible sides according to RAL/ DB ….., color ….. fine structure varnished in the style of DIN EN ISO 12944. coating material is UV-resistant and suitable for outdoor use.”

Installation and care of painted objects

If you want to feel happy about your metal garden objects for a very long time, remember that they need to be cared for. Please regularly check for damaged spots on the surface, so that these spots do not turn into a germ cell for surrounding color layers. Please do so at least every 6 months.
Especially the transition zone between garden object and ground is vulnerable to damage during the installation process, e.g. when objects are dragged over the ground or stalled on hard underground without protective interlayer (e.g. riprap, moraine gravel etc.). As a protective layer we absolutely recommend nonmetallic material like plastic or rubber mats.
