Classification of fittings and selection features

Rebar is an essential building material used to create various types of frames. It varies not only in diameters but also in technical characteristics.

Which reinforcement should you choose for specific purposes?

Based on its characteristics, reinforcement is classified into separate categories. Some products are used to manufacture reinforcement cages. https://alfa-stl.ru/catalog/armaturnye-karkasy/, others are used to create reinforced structures, etc.

Smooth A240 rebar is produced without ribbing. It is manufactured using the hot-rolled process, which provides excellent flexibility. This type of rebar is widely used for tying. The smooth surface reduces additional stress while maintaining the cross-sectional efficiency. The circumferential diameter remains uniform throughout the entire length of this product, providing increased strength compared to its ribbed counterpart. This type of rebar is widely used in the production of steel products, including metal mesh, fencing, and fences. However, it is unlikely to be useful for pouring foundations unless the loads are light.

A500C is a ribbed rebar used for pouring foundations and in the production of reinforced concrete structures and products. The ribbed surface ensures a stronger bond with the concrete mortar, resulting in a reliable and durable finished product. This structural material is characterized by excellent welding properties. It serves as the foundation for the most durable concrete frame structures. Steel bars of this type are the most common and in demand. A500C rebar https://alfa-stl.ru/catalog/armatura-a500s/ The price per ton is set at a fairly reasonable level, which is why it can safely be called universal, as it is the "golden mean" for all criteria.

A400 is externally ribbed rebar made from special grades of steel. It boasts increased strength due to the technical properties of the raw material. Essentially, this reinforced rebar is ideal for creating concrete structures with significant load-bearing capacity. It is resistant to rupture and pressure. This rebar can even withstand extreme temperatures thanks to being smelted from low-alloy steel grades. However, these products cannot be welded; connections are only permitted using wire tying.

For construction work, 12 mm diameter rods are used to construct the main frame. Thinner rods, 6 mm and 8 mm, are suitable for tying the structure together. If exposure to extreme temperatures is expected, it is recommended to consider heavier diameter rebar, ranging from 14 to 40 mm.
