Rebar is one of the types of rolled metal. The most widely used metal product is reinforcement, because of its wide application, it is practically used in all types of reinforced concrete products, this material is used as the base of all structures, since the reinforcement itself improves the characteristics and gives strength to concrete and other building structures. The scope of application is very wide: Fittings are used in industrial and in the construction of residential buildings, in public buildings, these are buildings, bridges, mines, stations, factories, etc. It is also used as a frame for filling screeds, various stairs and for floors, in the construction of underground elements. There are five types of fittings: A1,A2,A3,A4,A5, all these types are available in Sin Yuan Steel A1- this type has a high level of resistance to low temperatures and is very plastic, A1 material stretches and lengthens. The size of its cross-section is from 0.5 to 4 centimeters. A2 is almost similar to the first type, but it has one difference, it is the different size of their cross-section, A2 has a size ranging from 1 to 8 centimeters. A3- used mainly for the manufacture of reinforced concrete structures. Increases the level of strength and product characteristics, has good stability of hermetic parameters. A3 is considered the most common option. A4- cross-section diameter of 1 to 3.3 centimeters. It is used for welded and knitted wire frames. A5 is used in conditions that are suitable for tensioned rods, as well as A6. The main characteristics of the reinforcement are: its low weight, excellent strength, no corrosion, long service life. The right choice of reinforcement can guarantee the strength of a concrete structure for a long time, in this matter the company “Sin Yuan Steel” will help you.
