Basalt roving is used in different industries. Itâ??s used for production of the following products: Rebar for concrete reinforcement Profiles and pipes High-pressure vessels Geogrids Various types of fabrics Basic technologies of basalt roving processing are the following Pultrusion, Filament winding, Weaving, Multiaxial fabrics production. Direct roving is a ready â?? to â?? sell continuous one-end strand produced in the drawing process and wound on bobbins with 200 mm internal diameter.The main advantage of direct roving is zero catenary and excellent appearance. That is the reason why direct roving is used for production of fabrics and geogrids, as well for production of pultruded profiles and rebar. For other applications customers may need roving with much higher tex, comparing to direct roving, such as 2400 or 4800 tex. Some customers canâ??t use direct roving, because they need roving wound on bobbins with external unwinding. These products can be produced in form of assembled roving. Egular assembled roving consists of several single-end strands joined together without twisting on special assembling machine. It is supplied on bobbins with internal unwinding (tubeless, 76 mm internal diameter) or external unwinding (bobbins are wound on a tube with internal diameter of 76 mm and length of 270 mm).
