SEJ Board



We are the noted Exporter and Supplier of excellent quality SEJ Board made from cane fibre. It is a soft board impregnated with special grade of bitumen. It is a perfect base material for expansion joint filers. The board's compression and recovery characteristics conform to the U.K., U.S.A. and Indian Standards. SEJ Board that we offer is known for its excellent resistance to compression and outstanding recovery characteristics. Our SEJ Board is environmental friendly as opposed to the environment destroying thermo Cole or plastic expansion joint boards.
