Short Description
- Js designer tiles product is a manufacturer of Synthetic silicone rubber cover block mould. Which is used to produce high quality cover blocks.This mould is long life durable and provides you glossy finish. Cover block is a essentially a spacer that is used to lift the rebar matrix off the ground so that concrete may flow underneath the rebar and maintain a specified distance between the rebar and the shuttering to protect the steel reinforcement bars from environmental effects to prevent their corrosion and thermal insulation to protects the reinforcement bars from fire. In order to prevent corrosion of the rebar, it needs to be fully embedded in concrete. By code, it usually needs about 2 to 3 inches of coverage on all sides.So the cover block lifts the rebar up by about 2 to 3 inches and becomes a permanent and integral part of the poured concrete, ensuring that no part of the rebar sags and minimizes that required concrete coverage during the pour.
