Optimal thickness of aluminum lath

To manufacture roll-formed profiles and shutter boxes ALUTECH always uses the lath of strictly specified thickness. This ensures stable strength properties for every profile or shutter box.

High quality aluminum alloys

High quality of aluminum alloys used for production of extruded profiles has been confirmed by the report of the accredited test center of State Metal Powder Industry Institute (certificate No. BY/112.02.1.0.0263), where the alloys were evaluated. Only primary alloys are used for profiles production.

Lacquer coating

High quality of the lacquer coating of roll-formed profiles and shutter boxes has been confirmed by the test protocols of BASF Coating (Germany) and AkzoNobel (Sweden). The coating quality of ALUTECH extruded profiles and boxes has been confirmed by QUALICOAT certificate (Switzerland).

Alutech roll-formed profiles are made of aluminum lath with a double-layer polyurethane coating and integrated polyamide particles (PUR/PA). Polyamide particles are distinguished by its greater hardness and resistance to wearing out. They are added into the poly urethane base to improve the mechanical properties of the coating.

Features of the coating:

• high resistance to wearing out and scratches;
• resistance to stretching, cracking and layering;
• resistance to UV rays and temperature fluctuations;
• high resistance to corrosion;
• resistance to aggressive environments, such as detergents, solvent vapor, caustic, etc.,
• for the extrudedprofiles– lustre stability of smooth coating.

Even foam filling

Foam filling of Alutech roll-formed profiles is even, without voids and cavities. This ensures high resistance to loads and minimizes deformation.

Density of the standard density foam insulation of Alutech profiles is 67 – 70 kg/m³; high density foam insulation– 318-322 kg/m3. It ensures the best strength characteristics of the profiles.

Optimal winding parameters of the curtain

Geometry of the profiles (more than 13 parameters) are under constant control during the production cycle. Main factors are the profile thickness and profile height All parameters are always constant for each profile type and correspond to the set in technical specification.

Stable geometry and sickle-shaped ALUTECH profiles in the roller shutter curtain ensure excellent and constant winding parameters. This ensures significant saving on the roller shutter costs due to usage of the smaller-sized end caps and shutter boxes.

High corrosion resistance

• Resistance to corrosion of lacquer coating of the extruded profiles has been confirmed by the SEASIDE certificate. This is relevant for seaside regions, where the air is saturated with salt, in particular with chloride and iodine ions.
• High corrosion resistance of ALUTECH aluminum end caps has been confirmed by the tests in BelNIIS, R&D institute accredited under the Ministry of Architecture and Civil Engineering of the Republic of Belarus (certificate No. BY/112/02/1/0/0290) in compliance with GOST 9.308-85.

Quality compatibility of all roller shutter structural elements

Stable geometry of the profiles, shutter boxes, octagonal tubes, quality die casting of end caps ensure high quality of compatibility of all roller shutter components: shutter boxes with end caps, tubes with caps, electric motor adapters with other parts. This ensures that there are no gaps or protruding parts, contributes to trouble free operation of the drive and durability of theroller shutter , and also guarantees high quality installation.
