Fiberglass roving
At VISA COMPOSITES we offer Direct and Chop Roving fiberglass, ideal for open and closed molding. They provide high strength, easy processing, and compatibility with resins such as polyester or epoxy.
Single End Roving (Direct Roving): High strength and performance for industrial processes
- Individual continuous strands wound on spools or packages.
- Ideal for glass fabrics, mats, and manual or automated lamination.
- Allows precise control of density and strand orientation, ensuring uniform reinforcement in the final part.
Direct Roving is an essential reinforcement for processes such as pultrusion, filament winding, infusion, and RTM, standing out for its high filament integrity, rapid impregnation, and compatibility with automated systems.
Advantages of Direct Roving
Excellent flow and compatibility with impregnation machinery
Consistent dimensional stability
Improves curing times
Reinforces profiles, tubes, panels, and complex structures.
Filaments of constant diameter and without twist.

+Multi-End Roving (Spray Roving): Efficiency for fast and resistant laminates
- Set of multiple strands combined for resin spray-up applications.
- Perfect for large laminates, where the goal is to quickly cover extensive areas with fiber and resin.
- Ensures homogeneous distribution and rapid impregnation, improving production efficiency.
Spray Roving, or spray-up, is specifically designed for injection processes, a common method for manufacturing fiberglass composite parts, where chopped fiber is projected along with resin onto an open mold. Ideal for applications fast, high-volume applications with complex geometries.
Key benefits of Chop Roving
