Description
Aluminium profiles offer reliability and a long service life, with resistance to corrosion and temperature changes. These properties are essential for structures exposed to moisture, wind and chemicals outdoors. Low weight and simple profile geometry suit large and complex structures. The profile material contains no harmful or toxic impurities and releases no hazardous fumes when heated or in contact with other substances, which matters for prolonged sun exposure. No special maintenance is needed to extend service life. Extruded profiles are available in standard sections or to customer drawings.
