So what is aluminum extrusions? Everyone knows what a trim, baseboards, glazing beads, moldings Basically they are made of wood. Well, aluminum profiles are all the same trim and cornices, but only in aluminum. They are used in As a material for doors, windows, frames for cladding facades, etc. Also, aluminum profile used in the transport engineering industry in the manufacture of automobiles, carriages, ships and other rolling stock, including to the elevators. Apply it in the form of profiles of windows and doors, as well as any okantovochek.
Of special profiles manufactured housing for gas meters, equipment and even fire escapes. Specialists are divided profiles for standard and nonstandard. Standard – this wire, rod, channel, tube, angle Custom – profiles of figure section. From non-standard is just going to windows, doors and other building structures. Competition aluminum materials are wood and metal and plastic. Especially in the sectors of windows and doors.
But when facing facades and stained-glass main competitors are steel construction. Profiles made of 'pig' of primary aluminum, or the finished piece (the aluminum pole length 5,7-6,5 m). The main supplier of raw materials for Ukrainian producers is aluminum plant. Although some prefer to prepare the workpiece from Austria, Germany, Slovakia, 'he says, so is cheaper. The price for aluminum billet fluctuates constantly, it is bound to the quotations of the London Commodity Exchange of metals. Minimum price of a tonne posts abroad do not usually fall below $ 1,5 thousand, and the maximum 'is not growing higher than $ 2,1 thousand process of manufacturing aluminum profiles begins with casting of billets ( he described in a report on page 40). After this six-meter bar is cut into a special machine. The obtained poles supplied to the press where heated to 500'S and is forced through a die. The next stage '' oven aging. " Here come the process of aligning the mechanical properties and consolidation of the metal. In the 'oven aging' metal again heated to 200'S and 'fry' it in three to six hours. After this profile is almost ready.
