Ring Grooved Fibreglass Roller

Air Release Roller for Composite & Fibreglass Laminating

Ring Grooved Fibreglass Roller (RGFR) is a specialised laminating tool designed to remove trapped air and consolidate fibreglass during resin lay-up applications.
Featuring a ring-grooved metal roller head, this tool effectively forces out air bubbles while improving resin penetration into fibreglass mat, woven roving and reinforcement fabrics. The ring groove pattern enhances laminate compaction and helps ensure consistent wet-out, reducing voids and weak spots in the finished composite structure. Suitable for use with polyester, vinyl ester and epoxy resin systems, the RGFR is widely used in marine boat building, automotive panel fabrication, mould production and industrial fibreglass repairs. Compared to smooth rollers, the ring-grooved design provides superior air release and improved structural integrity. A reliable choice for Australian composite workshops and fabrication environments, the Ring Grooved Fibreglass Roller supports stronger laminates and a cleaner surface finish.
