Concrete Reinforcement
(21 Products)The reinforcement of a concrete structure is achieved by inserting steel bars or welded wire fabrics into newly laid concrete during the casting process. The incorporation of such reinforcements offers a degree of higher strength to areas that demand it most. Our metalwork range comprises a range of reinforcement products including reinforcing bars, coils and mesh, suitable for cast concrete application in industrial, agricultural and transportation sectors.
What Is Concrete Reinforcement?
Concrete reinforcement is a critical technique used in the construction industry to enhance the strength, durability, and performance of concrete structures. Concrete is strong in compression but relatively weak in tension, which makes it prone to cracking under tensile stresses.
Steel is one of the most widely used materials to reinforce concrete because of its high tensile strength, which allows it to effectively withstand the forces applied to the concrete.
Steel reinforcement, which can take the form of bars, wires, or mesh, is typically embedded in concrete before it sets. This reinforcement plays a crucial role in handling tensile and other loads that concrete alone cannot manage effectively, thereby enhancing the structure’s overall strength and stability.
Widely employed in diverse construction projects, including bridges, buildings, and roads, steel concrete reinforcement is essential for ensuring both the structural integrity and longevity of these constructions.
Reinforcement Bars
Reinforcement steel bars otherwise referred to as 'steel rebar', are high-tensile steel rods used to bolster and reinforce concrete and masonry structures, particularly concrete slabs.
The reinforcement process of concrete slabs sees rebars applied across the length and width of the slab at regular intervals.
While concrete exhibits high compressive strength, it can be prone to weakness under tension and is overall, quite a brittle material. By incorporating a reinforcing bar during the concrete pouring process, the tensile strength of the overall building project will be significantly enhanced.
Reinforcement Coils
EML (Expanded Metal Lathe) reinforcement coil serves to reinforce brick and blockwork by enhancing tensile strength and preventing cracking when used as a key for plaster when installed on ceilings and walls.
It is typically rooted in mortar joints (approx. every third course) to reinforce walls.
Reinforcement Steel Mesh
Steel reinforcement mesh is the ideal material for construction projects where flexibility needs to be tightly regulated. It is commonly employed as reinforcing fabric in concrete slabs, where its placement in the mix can dramatically enhance the structural integrity of any construction project.
Using reinforced mesh in concrete structures is a crucial part of creating a solid, reliable foundation. The mesh grips the reinforcing bars during setting to secure them tightly and make sure everything is well-grounded. From driveways to commercial buildings, footpaths, and even private residences - with reinforced mesh as your base you can build any structure securely!
Frequently Asked Steel Reinforcement Questions
What Is Concrete Cover?
The concrete cover, as specified by code ACI 130, is the distance between the embedded reinforcement or rebar and the exterior of the concrete surface. Concrete cover plays a vital role in increasing the durability of reinforced structures.
Why Is Steel The Most Common Reinforcement Material?
Steel reinforcement has played a crucial role in concrete construction for over a century, shaping the appearance of our cities and cosmopolitan landscape. Despite the rapid advancement of reinforcement technology, steel will most likely remain a staple in concrete construction.
One key reason for this is that concrete and steel have similar thermal expansion coefficients, meaning they expand and contract at nearly the same rate with temperature changes. This compatibility helps maintain the structural integrity of buildings and other structures.
Additionally, steel’s high tensile strength makes it an ideal choice for reinforcing concrete, as it effectively supports and strengthens structures under various loads and stresses.
