GRP Sandwich Panels

GRP refers to glass-reinforced plastic. It is suitable for a wide range of composite panels due to its unique advantages in high strength, lightweight, and fire rating. As a result, GRP composite panels are more and more popular in the use of construction panels like wall panels, prefab house panels, shelter & modular panels, etc..
