Aluminium is not the traditional component used earlier in the construction field. As in olden times there has been use of wooden and iron in the making of door or windows. But due to the increasing population as usually in the construction of houses also causes lack in the supply of wood or probably higher pricing, there has been shifting of call to aluminium. As the aluminium is originally not a metal or non-metal, it’s an alloy of iron and bauxite. So, it has the strength of both the components with some very interesting features of light weight with high durability and mechanical strength. The most preferable reason that people shifted towards aluminium door and window that due to moisture, iron gets rusted and wood gets swollen or damaged. As due to all this the aluminium door and window manufacturing business is been in demand very much,so its profitable to adopt this business as due to low capital requirement also.
