The characteristics of aluminium doors and windows meet the high standards of the market with respect to the high quality doors and windows which require minimum maintenance. The strength of aluminium profiles ensures structural stability of incorporated elements, and they are very light, which also ensures a long life of the incorporated elements. Another very important fact is that these profiles also save thermal energy, while their smooth surface makes maintenance significantly easier. The extensive selection of colours will ensure realization of architectural ideas without any obstacles, and therefore architects readily choose this material. In addition to its reliability and excellent insulation properties, they also provide an aesthetic experience, as their sharp and clear lines, as well as the high level of finish ensure modern appearance and luxurious style for your facility.
One of the main advantages of aluminium doors and windows as opposed to the wood, is that they show high resistance to weathering and generally high endurance and/or long life.
They also provide good thermal and sound insulation when combined with a corresponding glass. In addition to the longevity and reliability, the aluminium doors and windows are renowned for their aesthetical appearance, as well as a more extensive selection of colours which enable fulfillment of different wishes. They can also be used for construction of large elements for business premises, etc. It is suitable for use in areas with high temperatures and intense sunlight. It is easy to maintain, and only needs occasional wiping with a wet cloth.
Aluminium profiles are surface-finished, painted and protected by anodizing (anode oxidation) or powder coating. The anodized aluminium is most often painted in stainless colours (from light to dark ones), bronze, golden or natural aluminium colour. Through powder coating, the aluminium can be painted in any colour from the RAL colour chart. The choice is really immense, so the designers and architects face no limitations in designing.
Anodizing, i.e. anode oxidation is a protection applied in a thin layer of 15 - 20 microns. This procedure provides a special metallic colour and permanent protection from corrosion. Even though it offers a limited selection of colours, this protection method is very popular due to its attractive appearance and style.
Powder coating is the second method for aluminium finishing which provides an extensive selection of colours and is therefore adaptable to any design. The profile is first cleaned by a special procedure, after which the powder paint is applied by an electrostatic gun. After that, the paint is oven-dried at 180°C in order to achieve polymerization, i.e. the chemical reaction of powder particles networking and merging. The reasons behind the powder coating are above all the resistance to physical damage, getting the desired colour, but also the properties of polymer which additionally protects the aluminium profile upon application. The polymer used in powder coating is characterized by following properties:
