About GRP Interlocking Floors
DECK500, an interlocking anti-slip flooring system constructed from GRP, is used to create mezzanine floors, walkways and pedestrian bridge decks. Additionally, DECK500 is used in the water industry as effective odour control covers or to prevent water penetration in potable and waste water treatment plants.
DECK500 is a one-piece pultruded profile, 500mm over width, with a tongue and groove joint along the length of the plank to give a firm, sealable joint between the lengths of profile.
