Rebar Spacing in Concrete: Precision for Strength & Durability
Optimize Load Capacity and Crack Resistance with Expert Guidelines

Proper rebar spacing is critical to ensuring concrete structures withstand tension, shrinkage, and environmental stress. Our rebars are engineered for accurate placement, complying with ASTM, EN, and ISO standards to deliver unmatched performance in slabs, walls, and foundations.

Industry-Standard Spacing Guidelines:
✅ Slabs: 12–18 inches apart (center-to-center) for #3–#5 rebars, placed in the lower third of the slab.
✅ Walls: Vertical bars at 12–16 inches; horizontal bars spaced equally, tied at intersections.
✅ Foundations: Grid patterns with 12-inch spacing for heavy loads or unstable soils.
✅ Columns/Beams: Closer spacing (6–12 inches) with stirrups to handle shear forces.

Why Follow These Standards?

• Prevent Cracking: Evenly distributes stress to avoid structural failure.

• Corrosion Control: Maintain minimum 1.5-inch concrete cover to protect rebars.

• Seismic Readiness: Tighter spacing in earthquake zones (e.g., 6–8 inches for ASTM A706 rebars).

Our Rebar Solutions:
✔️ Pre-Cut Grids: Custom spacing and bends to save time and reduce waste.
✔️ Corrosion-Resistant: Epoxy-coated or galvanized options for coastal, humid, or chemical-heavy environments.
✔️ Global Compliance: ASTM A615, BS 4449, and JIS G3112 certifications.
