Welded wire reinforcement is an efficient and economical replacement for rebar as reinforcement in concrete construction. The use of welded wire reinforcement saves time and installation costs compared to standard rebar concrete reinforcement. Wires are welded into a sheet eliminating the time needed for tying rebar, and ensuring that the wires will not move when concrete is placed.
All Tree Island Steel’s welded wire reinforcement is manufactured to strict industry standards and complies with ASTM A1064 / A1064M. Galvanized coating options meet ASTM A641 / A641M standards.
Rust is OK! Studies by the Concrete Reinforcing Steel Institute (CRSI) have found that a moderate amount of rust does not affect the properties of the metal. In fact, tightly adhered rust on the reinforcing steel is not detrimental to bond, but rather can be beneficial. To learn more about the rust myth, click below.
Standard WWR is available with wire sizes of W1.4 (MW9.2) up to W4.0 (MW25.7) with standardized spacing of 4” (102 mm) and 6” (152 mm) for both longitudinal and transverse wires. Standard WWR is typically used for residential and light duty concrete reinforcement, and concrete crack control applications.
Our customized engineered reinforcing solutions save installation time by eliminating the need to tie rebar lengths. Wires can be welded in various sizes and spacings to meet the exact specifications for the project, and will hold all wires in the exact specified positions. Lap splicing is another important design consideration when placing engineered WWR. The ACI 318 guide is a comprehensive specification, which details the use of efficient lap splices which can reduce overall steel costs in a project.
Tree Island Steel pipe mesh and flexicage welded mesh products are available for all standard concrete pipe formats. Flexicage allows the formation of the bell to be flared to your exact dimensions. Pipe mesh is available in rolls or custom designed sheets that meet the strict tolerances for reinforcement placement in concrete pipe.
All mesh meets ASTM A1064 / A1064M standards for weld shear strength.
Tree Island Steel’s state-of-the-art manufacturing process is capable of producing welded sheets that are super flush-cut on all four sides. Our mesh is designed for the rigorous standards and safety requirements of the mining industry and are ideal for use in gabion cages.
Available in bright or galvanized finishes. Galvanized coating options meet ASTM A641 / A641M standards. All mine mesh and earth reinforcement exceed ASTM A1064 / A1064M standards resulting in enhanced weld shear strength.
Tree Island Steel’s concrete reinforcing wire is a premium wire for precast and cast-in-place applications, available with plain or deformed wire surface profiles. Concrete wire is available on wire carriers or in strapped coils with maximum package weights of 6,000 lbs.
Made from low carbon steel that meets ASTM A1064 / A1064M standards. Plain or deformed wire.
Tree Island Steel rebar tie wire is a high-ductility annealed wire for use in the construction industry, with uniform sized coils to fit standard tie wire reels. The annealing process produces a strong, flexible wire to facilitate quick tying.
Available black annealed or poly coated in 15, 16 and 16.5 gauge.
