Description :
Cover Block Moulds is used to produce high-quality cover blocks.
This mould is long-life durable and provides you with a glossy finish.
The cover block is 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.
