Reinforced Welded Mesh for Strengthening Features:
Welded steel is made with the same or different diameters of steel bars arranged in the vertical and horizontal directions in a certain pitch then welded together. All crossing points are formed together with the spot welding. This is a new, high efficiency, energy saving, construction material for reinforced concrete structures directly welded in the factory in modular style. This product is to replace the hand-stretched steel bar. Made with different types of hot-rolled (I, II, III) welded steel, cold drawn steel bars or cold-rolled ribbed steel bars welded.
Tatall manufactures steel reinforcing mesh of various types. Welded steel mesh is widely used in developed countries in the world.
Reinforced welded mesh mat or sheet applications:
Made by computer-controlled welding procedures, the welded steel bar mesh panel has ensured welding quality and steel pitch stability, without loss of steel strength and cross-sectional area of the original. It is widely used in concrete constructions.
Advantages:
Using of Tatall cold-rolled ribbed steel bars welded panels has the following advantages compared with traditional reinforced (carbon steel bar): (1) to save more than 33% of steel, reducing costs 10% -30%; ( 2) increase the speed of construction; shorten the duration of about 80%; (3) to improve the quality of engineering structures. The concrete reinforced with smooth reinforcement wire fabric with uniform distribution of strength. The deviation is small and the anti- cracking performance is increased by 75%.
