The Rib Revolution

Engineered Fishbone Grip Technology

Apex Dura features an advanced rib geometry inspired by the skeletal structure of a fish — engineered for superior concrete bonding, enhanced anchorage, and structural performance.

The Engineering Behind the Grip

RIB ANGLE

60° / 120° Alternating

RIB PITCH

6-8 mm

RIB DEPTH

Min 0.1 × Nominal Diameter

BOND AREA

+18–22% vs Conventional

COMPLIANCE

BIS 1786 – Fe 550 Grade

Resulting Technical Advantages

Mechanical Locking

Angled ribs create multi-directional resistance against slippage under seismic and load stress..

Bond Uniformity

Alternating rib geometry ensures even stress distribution and reduces micro-cracking.

Fast Bond Formation

Optimized rib spacing enables quicker concrete grip and faster anchorage.

BUILD FOR
INDIAN CONDITIONS

Heavy RCC usage in infrastructure projects

High humidity coastal and monsoon zones

Fast-paced construction timelines

Seismic activity requirements

PERFORMANCE TESTED

In the toughest environments across India
