Horizontal Grooved Paddle Roller

Air Release Roller for Fibreglass & Resin Laminating

Horizontal Grooved Paddle Roller (HGPR) is a specialised laminating tool designed to remove trapped air and evenly distribute resin during fibreglass and composite lay-up applications.
Manufactured with a horizontally grooved aluminium or steel head, this paddle roller effectively consolidates fibreglass mat, woven roving and other reinforcement fabrics by forcing out air pockets and excess resin. The grooved design improves resin flow while ensuring consistent fibre wet-out, helping prevent voids that can weaken the finished laminate. Ideal for use with polyester, vinyl ester and epoxy resin systems, the HGPR is widely used in marine boat building, automotive panel fabrication, mould making and composite repairs. Compared to flat rollers, the horizontal grooved profile enhances bubble removal and laminate strength, resulting in improved structural integrity and surface finish. A must-have tool in Australian fibreglass workshops and industrial composite environments, the Horizontal Grooved Paddle Roller supports professional-quality laminate performance and durability.
