A500C fittings: what is it, what is it used for, technical specifications

The armature is a product of rolled metal, widely used in various spheres of construction. It is a product of metal and steel, rarely - non-ferrous metals, which is intended for use in reinforced concrete structures, for reinforcing concrete.

A500S fittings: what is it?

There are many types of different armatures. In this article, consider the A500C fittings. This type of material (guest 52544 2006) is a rod of brand A5 with a diameter of 6-12 millimeters.

The letter A means that it is a hot-rolled reinforcement reinforced mechanically and thermally. The letter C says that this armature is weldable. A number of 500 indicates the yield strength of the product.

Armature 10 А500С theoretically weighs 0.617 kg. The average cost is 22,700 rubles per ton.

Armature 12 A500C has a weight of 0,888 kg. In a ton 1126.13 meters. The average price is 25000 rubles. Per ton.

Using

This type of fittings (GOST 52544 2006) is used to reinforce or reinforce the simplest reinforced concrete in accordance with GOST 5781-81 or load-bearing structures in accordance with GOST 10884-94.

Classification

Also, this construction fittings are classified into distribution, installation and working. In addition to this, in terms of the difference in strength characteristics, there is a non-tensioning and tensile reinforcement. Depending on the profile is divided into the reinforcement of the periodic profile (a2) and smooth (a1).

Sometimes a reinforced reinforcement is used that has the index T.

Manufacturing

Considering the question: "Armature А500С: what is it?" - one can not but mention its production.

More often for the manufacture of this brand, two methods are used: hot-rolled and cold-drawn.

With the help hot-rolled method is made rod, and cold-drawn allows to produce wire and rolled reinforcement. It should be noted that the core structural reinforcement has greater strength characteristics than other types.

It should also be noted that this class of reinforcement can be used at negative temperatures up to -55 degrees, in addition, it is permissible to use arc welding with hooks of arc-shaped connections.

Benefits

• A quantitative reduction in the consumption of reinforcement on the structure due to an increase in the design resistance to loads.
• Economical due to the low cost of thermomechanical processing.
• Unification - involves the replacement of all classes of goods A400, A300 and A240 with new fittings.
• Reliability, due to the lack of creating a zone of podkalki on the welding site, and excellent plastic properties.

disadvantages

1. Possible mistakes during the construction of houses, when in constructions that are designed for the A500S armature, accidentally applied the A400. Currently, this is trying to eliminate the marking. Previously, the new fittings differed in profile, but different factories make incisions on different products than confuse consumers.
2. Illiterate and incorrect treatment, which becomes a real wreck, the long influence of elevated temperatures can lead to the tempering of the steel, which can lead to loss of its mechanical properties.
3. Reduced corrosion resistance, because during the manufacture of the armature heat treatment is carried out, after - a massive attack of water to quickly take more heat. Consequently, this does not create a layer of scale, which protects against corrosion.
4. Uneven mechanical characteristics along the length of the rod. Most often this is characterized by domestic products, because obsolete equipment and technologies are used. Similar problems are absent in European factories. In particular, such a problem is perfectly solved at the Turkish metallurgical plant, equipped with European high-precision technology, which makes it possible to achieve uniformity of mechanical properties throughout the core.

Cold-formed reinforcement

Cold-deformed armature А500С - what is it? This type is made, as the name suggests, by cold deformation. The method is often used to produce small diameter products (3-12 millimeters), but in some countries it is widely used in the construction process. The main problem of their manufacture is the availability of finished rod with stable characteristics.

Visually similar kind of reinforcement can be determined, because it does not have a side edge and there are three or more profiles. Such products are quite effective in the factory and are used on automatic lines.

One of its common types is known as a welded mesh, in which there are no scale completely. This is why contact welding can be used in its application. It is possible to weld structures even in the environment of protective gases. The minus of such products follows from its own advantages: first of all, the reinforcement, in the absence of scale, rusts very quickly, and welding of such fittings using a conventional electrode is not allowed.

Select Valve

When choosing a cold-formed reinforcement, it is necessary to pay attention to the manufacturer, because many factors influence its quality. It is for this reason that it is better to give preference to enterprises that produce their wire rod, for example, the Belarusian Metallurgical Plant, Magnitogorsk Iron and Steel Works or the Cherepovets Steel Rolling Plant. However, it is worth mentioning that the greatest success in quality assurance was achieved by the plant of concrete products No. 18.

So, we have considered the question: "A500S fittings: what is it?" Do not forget about unscrupulous manufacturers. At this time, many manufacturers deliberately hide in the designation A500C the abbreviation of x / d, which should be written at the bottom, indicating the method of production of the product. In general, the use of such fittings is very effective, because it is not inferior to hot-rolled steel by its characteristics and even surpasses it in many respects
