- The first violin here is the paintwork, - the specialist notes. “That is why ALUTECH thoroughly tests the coating of roller shutter systems in accordance with European standards.
The coating of the ALUTECH roller shutter profile consists of two layers with separate firing - a base layer and enamel. The base coat helps protect against corrosion and uniform application of the topcoat. Enamel is a polyurethane coating with polyamide particles that improve its mechanical properties. The presence of two layers ensures uniformity of color and also guarantees resistance of the coating to abrasion.
Challenges start with color controlwhich is carried out on tape samples. To do this, the sample is compared with a standard using a spectrophotometer - an instrument that measures the color difference coefficient. For ALUTECH roller shutters, it is always less than one, which guarantees complete color matching, even if the profile was produced at different times. You will not have to be shocked when you see a "zebra" - a roller shutter, the lamellas of which have different shades.
For abrasion control roller shutter fabric is artificially aged, imitating opening and closing
roller shutters during operation. After that, the coating passes strength test, in which a plate with a paint-and-lacquer coating is bent up to 180 °, and then compressed in a vice until the sides fully touch. Even in such harsh conditions, the ALUTECH coating does not crack or peel off.
To make sure that the coating is not damaged by stones thrown by hooligans or branches caught in the wind, it is tested for impact resistance … The successful operation of ALUTECH roller shutters in the coastal regions is guaranteed by their anti-corrosion resistance … To check this parameter, roller shutters are immersed in a salt mist chamber for 1000 hours or more.
The multistage verification system also includes testing of the finished web. For this purpose, the ALUTECH roller shutter is installed in the opening, and up to 3000 lifting and lowering cycles are performed. The roller shutter is constantly monitored for scratches, abrasions and other visible damages.
But how to check, does the manufacturer really test roller shutters? Make sure you have the appropriate certifications. Thus, the quality of the paint and varnish coating of roll-rolled profiles and roll-formed protective boxes "ALUTECH" is confirmed by the test reports of BASF Coating (Germany) and AkzoNobel (Sweden). The quality of the coating of extruded profiles and boxes "ALUTECH" is confirmed by the QUALICOAT | SEASIDE certificate (Switzerland).
Strict quality control guarantees that ALUTECH roller shutters will delight you with a first-class appearance for many years. Choose a uniform color of the canvas and the absence of scratches, abandon the "zebra" in favor of really high-quality ALUTECH roller shutters!
