A 50 MM PVC Cover Block is an engineered, heavy-duty polymer rebar spacer designed to maintain a fixed 50 mm (2-inch) distance between structural TMT steel and horizontal plywood shuttering or vertical wall formwork. The distinctive jet-black color is a result of blending high-density carbon-black compounds into the polymer melt, which serves as a critical UV stabilizer.
This additive prevents the plastic from suffering structural fatigue when exposed to the harsh environmental conditions typical of active construction sites. Our cover blocks are manufactured using high-density, injection-molded Polypropylene (PP) and PVC polymers, ensuring they deliver the rigid physical separation required to meet structural design tolerances.
Beams, columns, and heavy infrastructure elements are subjected to immense structural stress. A dedicated 50 mm protective boundary layer of concrete is mandatory to ensure the longevity of these elements. Utilizing a 50 MM PVC Cover Block ensures precise positioning of steel reinforcement while protecting it from environmental degradation.
For project managers and structural engineers, the reliability of a cover block is determined by its material consistency and resistance to site conditions. Our 50 MM Cover Blocks are infused with carbon-black UV stabilizers, ensuring they do not crack, turn brittle, or degrade under the intense heat of the Indian sun.
