What are fittings?
Metal fittings are the "bones" of any concrete product. It is a collection of steel elements that reinforce the final material. Reinforcement is divided into rigid (rolled I-beams, channels, corners) and flexible (separate rods of smooth and periodic profile, as well as welded or knitted meshes and frames).
The main function of metal reinforcement is to resist loading and tensile stresses. Reinforced concrete structures collapse quickly when exposed to stress. Reinforcement of concrete blocks and other structures requiring reinforcement provides:
maximum strength;
durability and reliability;
resistance to loads.
Buying fittings will not cause you any difficulties: in any city there are many companies that sell metal products, as well as provide services for its delivery to a construction site. Metal fittings are sold in the form of skeins, wholesale and retail.
Reinforcement types
Today in the construction industry, rods are used, produced by the cold-drawn or hot-rolled method. A metal product is distinguished by the type of workpiece used at the time of manufacture of the steel alloy. It is possible to use additional heat treatment for thermally hardened rods with improved mechanical characteristics. The cost of such fittings is 30% more than usual.
According to their purpose, metal fittings can be divided into prestressed and non-prestressed. Metal products of the first type are more durable, since they are produced using a special technology, pulling the reinforcing rods as much as possible and then pouring them with a concrete solution in special forms.
Depending on the type of profile, the fittings are smooth round and with a periodic profile, and according to their purpose they are divided into assembly, distribution or work fittings.
There is a separate category of metal products - this is rigid steel reinforcement, produced in the form of T-beams. This reinforcement is used to strengthen multi-storey buildings and special structures.
Application of fittings
As we have already said, the scope of application of fittings is construction. Steel meshes and rods of various types are necessary when it is necessary to strengthen the structure, prevent stretching and cracks in building systems.
Consider the following factors when choosing metal fittings:
material type;
product shape;
production method;
way to use.
The correct choice of metal fittings is a guarantee of the reliability of the structure and a long service life.
