“GRETA” block board is manufactured with pine wood which is imported from New Zealand. pine battens are passed through planner to avoid the gap during their assembly so the final block board becomes gap free. Each batten is treated with chemical to prevent termite and borer attack. Assembled block boards are hot pressed by using gurjan core.
To manufacture water proof block board, battens are also coated with PF resin to get the extra strength. Block board are calibrated by using wide belt sander to get the equal thickness and smoothness.
