Concrete Reinforcement Products and Accessories

Concrete is a widely used construction material, known for its compressive strength. However, it lacks the tensile strength needed to withstand various structural loads. To address this limitation, the construction industry relies on reinforced concrete, a composite material composed of concrete and steel. In this comprehensive guide, we’ll delve into the world of concrete reinforcement, discussing the products and accessories crucial for strengthening concrete structures.

Introduction to Reinforced Concrete

Reinforced concrete is a composite material that combines the strength of concrete with the flexibility and tensile strength of steel. This combination results in a monolithic unit capable of supporting a wide range of structural loads. To achieve this, various concrete reinforcing products and accessories are used, each serving a unique purpose.

Dowel Bars

Dowel bars are short, smooth cylindrical steel bars typically 18 inches long with a diameter ranging from 1.25 to 1.5 inches. They play a vital role in connecting two concrete slabs, such as in pavements, slabs, columns, and staircases. Dowel bars help distribute loads evenly between adjacent slabs, reducing joint faulting by accommodating slab contraction and expansion.

Tie Bars

Tie bars are deformed steel bars or connectors that interlock aggregate together, maintaining contact between rigid slabs. They are strategically placed across longitudinal joints and between edge joints and curbs or shoulders. Utilizing epoxy-coated steel, tie bars inhibit differential settlement and transverse cracking, enhancing structural integrity.


Reinforcement bars or rebar are essential components in reinforced masonry and concrete structures. These steel bars provide the tensile strength needed to reinforce concrete. Various types of rebar, including mild steel, deformed steel, and stainless steel, are available. Identification codes engraved on rebar help determine their type and grade.

Steel Mesh

A steel mesh is used to prevent concrete slabs from cracking and breaking, particularly in smaller projects. While not as strong as rebar, it effectively reinforces columns, walls, sidewalks, and slabs. Despite being made of steel, it closely resembles finely-woven material.

Trench Mesh

Trench meshes are designed for narrow spaces, residential footing trenches, paths, rock walls, and brick walls. These elongated sheets of mesh feature longitudinal diameters that can reach up to 16 mm, providing additional reinforcement where needed.

Rebar Ligatures

Rebar ligatures, often called stirrups, are formed in various shapes such as rectangles, squares, triangles, pentagons, circles, and hexagons. They are positioned vertically to reinforce columns and beams, enhancing compressive strength and securing the main reinforcing bars in place.

Bar Chairs

Bar chairs are four-legged steel structures available in different coatings like plain, epoxy-coated, galvanized, or plastic-tipped. They support reinforcement bars at specific heights within a concrete slab, ensuring proper concrete cover over the reinforcement. Bar chairs find applications in suspended slabs, slabs-on-ground, and staircases.

Tie Wires and Bar Ties

Tie wires are extensively used to secure and fasten reinforcing bars together. These wires, often made of ductile and durable steel, can be annealed, zinc-coated, PVC-coated, or galvanized for protection against environmental factors. Bar ties, on the other hand, feature loops on both ends, facilitating manual or tool-based fixing of reinforcement rods during concrete placement.

Tie Twister or Puller

Tie twisters or tie pullers are essential tools for securely fastening ties with reinforcement bars. They enable quick and robust connections, ensuring the integrity of the concrete structure.


Concrete reinforcement products and accessories play a critical role in enhancing the strength and durability of concrete structures. From dowel bars and tie bars to rebar and steel mesh, these components work in unison to create robust, load-bearing structures. Understanding their functions and applications is essential for constructing safe and long-lasting buildings and infrastructure.
