Building a house is a huge investment that requires not only the preparation of the appropriate project, but also the careful study of the smallest details. Reinforcing steel is an element that cannot be ignored during the construction of a building - it strengthens the structure and transfers loads that concrete itself cannot withstand. What brands and classes of reinforcing steel can be distinguished and what kind buy fittings for construction?
Reinforcing steel - characteristics
Reinforcing steel is produced at the steel and metallurgical plants of ROBMETALLSTAL LLC in the form of smooth or ribbed bars, wire rod and wire, as well as multi-element mesh. Steel, used for strengthening construction structures, is produced in two main ways — rolling and drawing. In construction, these elements are used, including for the construction of:
- foundations,
- blocked,
- columns,
- stairs
However, they are applicable not only for reinforcing concrete, but also for steel structures (for example, fences) or for the production of industrial equipment. The armature can have a round, square, rectangular or hexagonal section.
Rebars, grids and frames - practical information
Information about the types of reinforcement needed to strengthen the building can be found in the construction project - it specifies the exact number of rods, their shape, diameter, length, as well as information about the brand and class. If there is no access to such data, the relevant information should be requested from the architect.
The weight of reinforcing steel is indicated in tons. Providing the exact parameters of the materials needed to strengthen the structure in the project or cost estimate.
This simplifies the ordering of ready-made fittings, which manufacturers correctly cut or bend in accordance with the provisions of the documents. When buying elements, you should also not forget to add about 10% of the stock just in case, especially if you decide to cut the elements directly on the construction site.
Manufacturers of reinforcing steel, wholesalers and construction warehouses also offer elements combined in special frames and grids. These types of constructions are used to strengthen crowns, bridges, walls and tape foundations, columns, beams, and also to strengthen floors.
Brands of reinforcing steel
The steel specification is the most important element that should be considered when ordering fittings. The type of steel is determined by its brand and class. The first parameter describes the technological properties of steel, for example, determines the alloy from which it is made. There are five main types of reinforcing steel, including unalloyed and low-alloyed steel without additional processing, hardened steel with a high yield strength or cold-hardened steel. The steel brand is marked with a sequence of symbols consisting of letters and numbers, for example St0, St3C, 18G2. In turn, the class of steel is a parameter that determines its strength, for example, for bending. Manufacturers mark it with a letter and a Roman numeral, for example, A-0, AI, A-II, A-III.
