Stelcover Cover Blocks

STELCOVER Cover Blocks ensure proper spacing between rebar and formwork, preventing rust and ensuring strong, durable structures. They are M-40 grade with excellent load-bearing capacity and strong bonding with concrete.

Cover blocks are spacers placed between reinforcement bars (rebar) and the formwork to maintain the specified concrete cover. This protective concrete layer shields steel reinforcement from moisture, corrosion, and fire exposure while ensuring proper structural performance.
