Alkali-resistant roving is used for spray up or mechanical continuous forming of GRC. It is the base material used to make glass reinforced cement (GRC). Light, high in strength, incombustible and easy to design and shape. GRC products are widely used in the building industry as boards, corrugated proofing sheets, division panels, internal and external insulation panels, decorative panels, dust panels, cable boxes, drainage channels and for garden features and artistic sculptures. AR Chopped Strands also available.

Individual and Bulk Packaging
Each roll (about 18kg) is packed in a polythene bag and 48 rolls are packed in a carton. The assembly is wrapped onto the pallet and protected by a shrink-wrap film. A vertical FRP tube reinforces the 4 corners of the pallet. There are 20 pallets per 20ft container. Total net weight is about 17,500 kgs (38,588 lbs).
