Description
Lightly resin bonded mattresses (LRB) consist of fine fibers 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.
