The TMT bars are systematically arranged in a grid pattern, placed both horizontally, vertically and diagonaly to ensure uniform load distribution and effective crack control. This configuration enhances the structural integrity of the precast structure under continuous and heavy load conditions. All TMT rebar bars are made of prime steel according to ASTM A615 Grade 60 (CSAG30.18.21)

» Corner Strengthening/Edge Reinforcement:

• - Additional overlapping reinforcement is provided at all required edges.
• - Prevents stress concentration and minimizes cracking under high load impact

» Overall Configuration:

• - Forms a rigid box-type reinforcement cage
• - Ensures uniform load transfer from the cover surface to the supporting manhole walls

» Structural Benefits:

• - High load-bearing capacity
• - Excellent resistance to bending and shear forces
• - Superior crack control and long-term durability
• - Suitable for heavy traffic zones and utility infrastructure

» Customized frame structure are available as per project requirements :
