Rebars are steel bars made from carbon steel and are ribbed along their length to improve bonding with the concrete. Their main use is to reinforce concrete and masonry structures by providing them with tensile strength, enhancing their durability, stability, and resistance to various loads and environmental conditions. The rebar has become one of the most essential components in a wide range of construction projects, from buildings and bridges to tunnels and water retaining structures.
Rebars Prices
The prices of rebars vary depending on their grade, size, dimensions, and length. On average, the lowest-priced rebar goes for around ₱175.00 to ₱541.00.

Advantages of Rebars
Enhanced Structural Strength – Rebars provide tensile strength that helps reinforce concrete structures, significantly improving their load-bearing capacity, durability, and resistance to bending, shear, and other forces.
Improved Structural Stability – By reinforcing concrete structures such as columns, beams, slabs, and walls, rebars help enhance the structural stability and integrity of buildings, bridges, highways, and other infrastructure projects, reducing the risk of collapse or failure.
Flexibility in Design – Rebars are available in various diameters, lengths, and configurations, offering flexibility in structural design and allowing engineers to tailor reinforcement solutions to meet specific project requirements.
Cost-Effectiveness – Despite the added cost, the use of rebars in reinforced concrete structures can be cost-effective in the long run due to increased structural integrity, reduced maintenance, and longer lifespan of the structures.
Disadvantages of Rebars
Corrosion Risk – In environments with high humidity, exposure to saltwater, or chemical exposure, rebars are known to be susceptible to corrosion over time which can result in deterioration of the concrete structure and compromising its structural integrity.
Labor-Intensive Installation – Installing rebars in concrete structures can be labor-intensive, requiring skilled labor, specialized equipment, and careful placement to ensure proper alignment, spacing, and anchorage, adding to the total construction costs.
Complexity – Designing and detailing reinforced concrete structures with rebars requires expertise and careful consideration of factors such as loadings, building codes, material properties, and construction practices, complicating the design process.
Potential for Concrete Spalling – If rebars are not adequately protected from corrosion or if the concrete cover is insufficient, the expansion of corroding rebars can lead to concrete spalling or cracking which could potentially compromise the appearance and structural integrity of the concrete structures.
