Metal

The bent channel of GOST 8278-83 has the P-shaped section (A with-shaped form of cross section) of the different sizes and the weight of 1 meter of a running channel. Make bent profiles or of rolled goryachekatny carbonaceous steel or of the carbonaceous constructional qualitative and low-alloyed steel. (See a photo) at manufacturing plant use the special profilegibochny machine to production of this section bent in a box for are flexible a metal profile. It is made this facilitated like a channel (the weight of running meter lower, than at a hot-rolled channel) with the rounded external corners unlike hot-rolled hire. Using cold hire, the element will have big resistance to deformations, as defines its advantages before others. The channel bent ravnopolochny GOST 8278-83 is applied at construction of buildings and constructions, to production of metal frameworks from a bent profile, partitions, etc. All channels well work for a bend and perceive axial loadings at the expense of what design durability in general and other technical characteristics increases. Types of a channel are distinguished on width of shelves, its sizes can fluctuate within 32-115 millimeters (the narrow shelf and a shirokopolochny profile). Height of a channel can change ranging from 50 to 400 millimeters. The Holodnognuty channel the sizes 10, 12, 14, 16, 20 is actively used in industrial and civil engineering at production of a metalwork as replacement of hot-rolled hire because of the smaller specific weight of a bent channel with thin regiments (from a steel sheet of iron), for reinforcing of concrete designs, in metal working, by production of cars, in automotive industry, for production of bridges, an easy roof and thin-walled columns, and also in other branches of a national economy. In housing construction the bent profile can be used as rigid fittings for concrete goods, in monolithic designs, frame constructions, for construction of fences, ladders, peaks and other metalwork of varying complexity. Use of easy steel bent profiles considerably loses the weight of a design and pressure upon the base at construction of buildings and constructions from the thin-walled profiles allowing to save up to 40% of money for metal costs in comparison with a factory rolled profile.
