Concrete - an indispensable material in construction.Because it is manufactured foundations, walls, bridges, and so on. D. It is rugged and durable, but it has ended, there is one rather significant drawback - it is not very resistant to stretching.To correct this situation, use special metal rods, called rebar.Rods poured the concrete for the structure, good resistance to both compression and tension.
Today released the most different types of rebar.It may be classified according to the method of manufacture or use or used for the manufacture of materials.Valves with a thickness not exceeding 10 mm, sold tangling.If the diameter profile of 10 mm, it is cut into bars in length 6-12 m.
produced two types of valves: c periodic profile (a term used by specialists) and smooth fittings.Forms of construction material in the first case may be coated or ribs or notches.There are sickle-shaped, circular and mixed species.These rods engage better with concrete, which ultimately provides a more solid structure.
Made fittings (types which can be used for a variety of designs ruggedized) of hot rolled steel by cutting.There is another way - a wire, in which the hot metal rod is pulled in.In the manufacture can be used as tempered steel and simple.
The building is also used for different types of steel reinforcement.Forms of it are intended for use in the construction of buildings of varying strength and purpose.In order for the consumer to sort out what kind of reinforcement is required in either case, the labeling used.For example, products manufactured classes of A240, A400, A800 and so on. D.
sale occurs welded and welded fittings, types which differ in that in the first embodiment can be used welding, and the other with this method of connection to the grid and frames becomesbrittle, which inevitably affects the rigidity of the assembly.Therefore
weld fittings assembled by binding the individual rods with the help of the wire.Also distinguish resistant to corrosive and unstable stretching equipment.In the first case the products are marked with the letter «C», the second - "K".
Purpose and types of fixtures can be very different.However, one thing is clear - without using it to build a strong and durable construction will fail.Steel framework is necessary in the construction of any building, even if it is a small private house.
addition to construction, there is another type of reinforcement - Stop.It is used mainly in the pipes to overlap the streams of liquids or steam, as well as to control them.Types of valves can be very different: Cranes, valves, valves, locks, and so on. D. Of course, without such reinforcement comfortable house not built.In particular, it is impossible to build without water and sewage systems.
