Prestige Block Board
Commercial Block Board
“Prestige” Commercial Block board is manufactured from the combination of selected seasoned, durable hardwood, timber battens and veneers. It is bonded with Urea Melamine Formaldehyde resin at high temperature and pressure which gives our boards an advantage over other commercial grade boards. The resin gives our board enough strength to resist warm water up to 8 hours.
