Aluminum is being used since a long time as a lightweight material for all construction and building works. Aluminum alloys are being used in every industry from Aviation industry to zip making. The aluminum extrusion strength to weight ratio is higher in case of aluminum to steel. The long life comes from the higher corrosion resistance of aluminum.
Aluminum rails can be used in different ways. These ways that increase the life of aluminum are,Anodizing of aluminum: The corrosion resistance of aluminum is further increased by a thin coating on aluminum. The anodized surface of aluminum prevents further oxidation of the corrosion of the aluminum.
Strengthen with wooden inserts: Wooden blocks inserted in the cavity of aluminum forms give added strength to aluminum and thus lighter sections can be used for the same work, further reducing the weight of structure.
Powder coating of aluminum: New painting techniques such as the powder coating add to the visual appeal of the railings. The overall effect of created by riot of color combination that are available is just amazing.
PVC coating: Aluminum can be coated after complete fabrication with PVC by various methods. This further increases the life of the aluminum products. It also gives a beauty treatment to the aluminum.
Many manufacturers are coming up with solution in use of aluminum in railings. The use of the bottom posts in which the aluminum verticals can be fixe, speed up the erection process. The DIY enthusiasts find such solutions very useful since it reduces the time required doing for such work. These posts are made out of PVC, CPVC or such manmade materials.
Aluminum alloys also find increased use in the manufacture of railings and this gives an extended life to railings. The alloying with other metals increases further the already high strength to weight ratio and corrosion resistance.
