Rock Mattress PVC Coated 6x2x0.23m

TerraStop® Rock Mattresses are heavily galvanized, hexagonal steel-wire mesh cage, traditionally used in applications such as slope protection, culvert aprons, creek, and channel linings where long term scour is an issue. Units are either zinc galvanised or an additional PVC coating applied to ensure extra durability for the surrounding environment. A more superior coating is also available for severe corrosive conditions such as marine environments. The development of a zinc plus 5% aluminium alloy known as Aluzinc is the next step in the fight against steel corrosion. A PVC coating on the Aluzinc alloy can be added for ultimate durability.
