Valves A240: classification, technical characteristics, scope

What is the A240 armature (GOST 5781-82)? This is a special auxiliary element that ensures the proper functioning of certain structures, devices and equipment. Armature is one of the types of rolled metal. It prevents the destruction of finished products and increases the strength of reinforced concrete structures, products in dozens of times, so that they can withstand enormous loads.

Modern Valve Classification

Depending on the functional purpose, the armature differs according to the chemical composition of the steel, the method of production, the main characteristics and the diameter of the section. The greatest demand is for valves of A240 class with a diameter of 10 millimeters. A wide range of products today offers many companies. On the market there is an armature, which is classified according to a number of parameters:

• Type of cross section. The reinforcement can be made in the form of a periodic profile with a smooth and smooth surface.
• Production technology. There is a wire cold-rolled and hot-rolled reinforcement. On sale, it comes in coils with wire skeins or rods.
• Method of use in concrete solution. There are unstrained and prestressed reinforcement.
• Method of strengthening. There is A240 reinforcement treated at high temperature by tempering or tempering, and produced by the method of cold strengthening by drawing or drawing.

Features of A240 valves

Like any other material, this type of reinforcement has certain properties that maximally characterize its quality. First of all, it is necessary to allocate flexibility and rigidity, if necessary, the rod can be given any shape, and the structure will not lose its strength. Due to special processing the A240 fittings withstand large mechanical loads and are completely resistant to corrosion. It is also worth noting that this material is durable and durable, and this allows it to be used in the construction of multi-storey buildings.

There is one subtlety in marking the A240 armature, if the letter "c" is indicated here, this indicates its weldability. Due to its low cost and the above qualities, it is in high demand.

Application technology

A240 fittings are sold in different lengths, therefore before the erection of walls and pouring floors the rod is cut to the size for the frame. The pieces are fastened together by welding or by wire.

The finished reinforced structure is installed in the required position and filled with concrete solution. After hardening, it acquires extremely high strength and the ability to withstand high pressure, weight, vibration and even a powerful shock wave, while maintaining an integrated structure.

Applications of fittings

Used valves A240 most in the construction industry. This production of various plates and poles, pouring floors, walls, columns, reinforced concrete structures and many other operations, where the main criteria are strength and reliability.

It should be noted that the reinforcement is used not only for the erection of reinforced concrete structures, but also for the manufacture of metal doors, window grilles, fences and fences in the adjacent areas, various handrails, stairs, stiffeners and many other products.

The armature can now be purchased in any specialized company, and without limitation in the standard and quantity. Products are available in any size, length and performance. Therefore, each person can purchase armature for himself according to the requirements of current circumstances, personal preferences and financial possibilities.
