Steel Mesh

What is Steel Mesh?

Steel mesh is one of the primary elements in reinforced concrete construction, created by cold drawing and ribbing S220 steel, which is then welded into a cage structure. It provides high strength and plays a critical role in reinforcing concrete structures, ensuring their durability and stability. This process enhances the concrete's tensile strength, making it an essential material in construction projects that require reliable and robust reinforcement.

Steel meshes are primarily manufactured in two types, depending on the way the slabs work:

1.R-type mesh for structural elements working in one direction.

2.Q-type mesh for structural elements working in two directions.

Applications of Steel Mesh:

As a building material, steel mesh is particularly used in floors, shear walls, retaining walls, foundations, site concrete, concrete roads, tunnels and galleries, as well as in channels and culverts. It enhances the structural integrity and durability of these constructions, ensuring long-lasting and safe performance in a variety of concrete applications.

However, there are also varieties of steel mesh used for garden fences, railings, and suspended ceilings. If desired, these can also be provided in hot-dip galvanized and polyester-coated (painted) forms. This offers additional protection against corrosion and enhances the durability of the steel mesh in different applications.

Advantages of Steel Mesh:

The yield strength of steel mesh is 2.27 times that of S220 steel and 1.19 times that of S420 steel. In other words, by using steel mesh, it is possible to achieve weight savings starting from 10% compared to other steels, along with time and cost savings of up to 25%. This makes steel mesh an efficient choice in terms of both material and project execution.

Project Design:

The types of steel mesh to be used are calculated based on the project moments and concrete class. Then, reinforcement plans are drawn according to the formwork plan. To avoid mixing up the steel meshes, two separate plans are drawn: the "bottom reinforcement plan," which addresses the effects of the openings, and the "top reinforcement plan," which addresses the support effects.

Additionally, within each reinforcement plan, a "steel mesh cutting plan" is prepared, showing the places and measurements where the meshes need to be cut to match the arrangement of the steel meshes. A measurement sheet indicating the amount of steel to be used is also included.

Standards and Specifications Related to Steel Mesh:
The standard related to steel mesh in our country is TS 4559. For reinforced concrete calculations involving steel mesh, refer to TS 500 and the regulations concerning buildings in disaster zones. Steel mesh can be produced in accordance with DIN 488 (German), ASTM A 185 (American), BS 4483 (British), as well as French and Greek standards. The position numbers in the Ministry of Public Works' price list are 04-305/1, 04-305/2, 23010, and 23011.
