Reliable strength for residential & general construction
ASTM A615 / A615M | Deformed rebars engineered for cost-efficient, dependable reinforcement.
Prime Steel Industry mainly manufactures Grade 40 and Grade 60 deformed steel bars in strict compliance with international standards, with an annual production capacity of 100,000 Metric Tons.
Steel is one of the most critical elements in construction, comprising approximately 40% of a project's total cost. We offer custom cut-to-length modifications for all clients, backed by reliable delivery across Pakistan.
Introducing Grade 40
The introduction of Grade 40 rebars brings the required structural strength and construction cost efficiency that modern projects demand. The use of Grade 40 rebars strengthens structures in a way that significantly mitigates the risk of damage caused by natural calamities, seismic activity, and other environmental factors — making them the trusted choice for residential and general construction.
Properties of Grade 40 Steel Bars
Grade 40 rebars manufactured by Prime Steel offer a minimum yield strength of 40,000 PSI. Its metric counterpart is Grade 280, with an equivalent minimum yield strength of 280 MPa and a minimum tensile strength of 420 MPa (60,000 PSI). This makes Grade 40 rebar an excellent choice for light- to medium-duty concrete reinforcing applications.
- Minimum Yield Strength: 40,000 PSI (280 MPa)
- Minimum Tensile Strength: 60,000 PSI (420 MPa)
- Standard: ASTM A615/A615M Compliant
Why Grade 40 Deformed Bars?
Prime Steel Grade 40 bars are deformed steel bars — rods of steel provided with lugs, ribs, and deformations on the surface. These deformations minimize slippage in concrete and maximize the bond between steel and concrete.
They carry higher tensile stresses compared to mild steel plain bars and can be used without end hooks, effectively limiting the development of cracks in reinforced structures.
