INROCK LRB MATTS - INNER ENGINEERING PRODUCTS & SYSTEMS PVT LTD

Lightly resin bonded mattresses (LRB) consist of fine fibres spun from a range of selected rocks melted at high temperature bonded with a thermosetting resin.

Lightly resin bonded mattresses (LRB) are light weight, strong, resilient, and easy to handle and cut to suit intricate shapes.

Facings

Lightly resin bonded mattresses (LRB) are available with galvanized or stainless steel hexagonal wire mesh on one side or plain.
