Colours and Finish

TECHNAL offers anodised finishes inspired by the surface treatments of metals and their alloys. Blending a raw, industrial character with refined, sophisticated colours, they enhance the inherent brilliance and depth of aluminium.

Painting offers an unlimited choice of colors with excellent color matching. Powder coating is by far the most common painting method today.

The colour durability of SAPA aluminium profiles is designed to withstand the test of time and weather, providing high-quality surface protection, maximum lifespan, and long-lasting performance for your building systems.

To achieve the right quality on the painted surface, it is important that the pre-treatment, application of the paint, and subsequent curing are carried out correctly. Pre-treatment is crucial to achieve maximum adhesion and durability. It normally consists of degreasing and pickling the surface, followed by a chrome-free chemical treatment. The pre-treatment is completed by rinsing the profiles in deionized water. Pre-treatment provides the best possible corrosion resistance and adhesion when painting products that are to be used outdoors.

The pre-treated profile is covered with polyester powder. The powder, polyester, is applied to the profile by electrostatic or friction charging, after which the powder is cured in an oven at 180ºC. Powder coatings are applied and cured without any solvents. The ventilation air from the powder application is purified in efficient purification plants. Powder that “misses” the profiles is collected in a recycling system and returned to the spray gun.

Inspection is carried out at a viewing distance of 3 m, in normal daylight without direct sunlight or with interior lighting of 600-1000 lux. The profile surface should be viewed for 5-10 seconds. Impurities and other defects that are not clearly visible in normal daylight from this distance are not valid grounds for complaint and compensation.

Naturally anodized with unsealed aluminum is colored with organic or inorganic dyes. After coloring, the oxide layer is sealed.

Similar to the simple coloring process, coloring is done in a separate step after anodizing. Through the action of alternating current, the pigments, which consist of tin salt, are deposited at the bottom of the pores. The color scale ranges from sepia to black. The colors, designated Hx-5 to Hx-50, have very good color fastness.

Aluminum profiles surface treated with Natur or Hx anodizing method according to SS-EN ISO 7599:2018. The standard defines sealing, abrasion, corrosion, gloss, and light resistance. The standard also specifies requirements for performing inspections and the test methods to be used.

Our strong commitment to sustainability is reflected in the use of recycled, low-carbon aluminium from Hydro in all of our products as standard. This approach brings a unique and meaningful response to the growing demand for environmentally responsible building materials.

Our solutions are 95% recyclable. When we design our products, we act for circularity by taking into account their disassembly and re-use at the end of their life. 

Our solutions are made with at least 75% of recycled components including aluminium, EPDM, polyamide.
