What is GRC ?
Imagination is your only limitation.
Glass Reinforced Concrete (GRC) is a stone made from multiple elements, including fiberglass. That means it’s lighter than concrete, tougher than nails, and more flexible than a lubed-up contortionist.
As one of India’s leading suppliers and manufacturers of the GRC stuff, Ashirwad GRC is allowed to make big claims like that. In fact, creating customized GRC products is our specialty. For more information on how we can help you create innovative structures, click here to download our E-Brochure
What is GRC ?
Glass fiber reinforced concrete is a type of fiber-reinforced concrete. The product is also known as glass fiber reinforced concrete or GRC in British English. Glass fiber concretes are mainly used in exterior building facade panels and as architectural precast concrete.
