Among the few good players in the market of chequered ply in India, KPI Chequered plywood can be counted as one
among the best. Chequered floor boards are high density exterior grade plywood produced under high heat & pressure
using un-extended PF resin. The ply has a chequered pattern on its surface that comes from the wire mesh put during
pressing. Because of high pressure the panel develops high density that sustains the rigors of flooring in public use. This
not only eliminates the smooth surface of ordinary plywood but also makes it anti-slip plywood.
The plywood combines
enhanced mechanical properties with extreme wear proof qualities, besides being resistant to corrosive agents. The
basic purpose of making plywood which is anti-slip and anti-skid is to accommodate it in the application of flooring that
too in heavy vehicles and large containers. The advent of chequered plywood has revolutionized the flooring in those
sectors and created fresh avenues in other sectors too.
