Powder Coating

Our fixtures, poles, and accessories are always coated in multiple stages, using different methods depending on the base material used. Iron components are chromated, and aluminum parts are anodized. We also purchase large quantities of high-quality pre-galvanized steel sheet, or alternatively, components and parts are sent for electroplating or hot-dip galvanizing. Before the actual coating, all parts are washed with alkaline detergents and phosphates in a closed, environmentally friendly system. The parts are then coated in one or two stages with a special polyester powder coating designed for outdoor use. The coating thickness varies between 80-110μm (micrometers) to provide the best corrosion protection in our Nordic climate.

Hot-Dip Galvanizing (Galvanization)

Zinc is a natural element that occurs in the Earth's cycle. Zinc melts at lower temperatures than other metals, which means less energy is required for hot-dip galvanizing, which also offers several other benefits, such as long lifespan, a neat finish, and very low maintenance.

The hot-dip galvanizing process involves cleaning the material of grease, oil, rust, and other contaminants by immersing it in a bath of molten zinc at a temperature of 460ºC. This creates a strong chemical bond between the steel and the zinc, ensuring durability and providing a very strong protection against corrosion—i.e., rust protection that shields the metal for a long time. Another major advantage of hot-dip galvanizing is that even if the surface coating is damaged, the galvanizing continues to protect the underlying metal. There is no better corrosion protection for iron and steel! Galvanization creates a resilient surface with an incredibly long lifespan and is virtually maintenance-free—an ideal option for situations where high quality and longevity are critical. (The surface finish of the galvanizing may vary.)

Anodizing

Anodizing is a common surface treatment method used to provide aluminum products with a protective coating and increased resistance to corrosion. It is also used for coloring, texturing, and decoration of surfaces, for durable color and gloss, as an electrically insulating layer, or as a surface coating before bonding or painting. Anodizing is an electrochemical process that strengthens the natural oxide layer. Another term used for the same process is "anodizing" (or "anodization").

Dark Oxidized Copper

We process genuine raw copper by first etching (chemical cleaning) and then oxidizing the material in chemical baths at our factory in Bankeryd. In some cases, the material is also coated with a thin layer of protective lacquer. This is done to protect the product during the manufacturing process and also to slow down the natural aging process. Over time, the protective lacquer will break down due to environmental factors, and the already oxidized copper will gradually develop an even darker, greenish, and exclusive appearance that is unique to this metal.

When we perform oxidation, the copper undergoes aging that would normally take about a year.
