Glassfier Alkali-resistant Roving
Introduction:
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). With the properties of 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 （with cutting length 6,12mm）also available.
Features :
