Specifications A3 rebar , assortment and features of the application

Whatever claimed advertisers and various "experts" cheaper composite rebar can not completely replace the metal fittings.Although, if only because no standards and specifications for its application still does not exist - all the regulations are purely advisory in nature.And in the corners of the tape, as well as for bonding parts of carcasses of plastic "connectors" in general may not be used.

All steel rods is divided into several classes, that determines the specificity of their application.Consider the technical data "A3" brand reinforcement.It is produced by the method of hot rolling and has a periodic profile.To make the bending strength - two ribs (corrugated surface) that "twisted" spiral.Raw - high-carbon steel (GOST number 14959 from 1279) or low-alloy (GOST number 380 of 1994) .

Features reinforcement

• Good grip with artificial stone.
• strength.
• necessary flexibility.
• cost lower than that of counterparts.

But there is a drawback - the figure "turnover" is quite high (sometimes use the term "low limit"), which is somewhat limits the scope of the use of this reinforcement.

along the rods are various notations that say about these or other properties of the material.Decrypts them so:

• K - resistance to corrosion;
• T - metal, which has high strength, achievable by heat treatment;In
• - hood reinforced;
• C - Excellent "weldability" (except for the brand '35GS ").

Range A3 rebar

• cross section bars 6 - 80 mm.
• Specific gravity 0.222 - 7.99 kg / rm.

Products section of 8 mm or less sold in coils, and 10 -. Rods in length from 6 to 12 m

On the value can only say roughly, because the price depends on the volume of purchases.The larger the party, the substantial discount.On average 1 ton rod will cost about 26 000 rubles.
