1200gsm Biaxial Fibreglass Fabric Full Roll | Structural Marine Fibreglass
Transom Rebuild | Hull Structural Repair | Stringer Replacement | Keel Repair | Production Boatbuilding
1200gsm Biaxial Fibreglass Fabric in a full roll format is the smart buy for professional boatbuilders and marine repairers who regularly need heavy structural reinforcement. Because it’s supplied as a full roll, it delivers the best value per metre for production builds, large structural repairs, and any project requiring multiple layers of heavy biaxial throughout.
For smaller or one-off repairs, this fabric is also available per metre with no minimum order.
Marine Applications
1200gsm Biaxial Fibreglass Fabric is purpose-built for high-load structural work including full transom rebuilds, stringer replacement, keel repair, hull structural repairs following impact or osmosis damage, heavy sandwich panel skins, and deck reinforcement under high-load fittings. For transom rebuilds in particular, alternate with CSM interleaving layers — as a result you’ll build a stiff, well-bonded laminate efficiently and in fewer total plies.
Key Properties
- Balanced 0°/90° fibre orientation delivers in-plane stiffness and strength in both axes
- Builds laminate thickness rapidly — fewer layers, less layup time
- Stitched construction keeps fibres straight, resulting in consistent mechanical performance
- Compatible with epoxy, polyester, and vinyl ester resin systems
- Full roll supply ensures consistent material from the same production batch throughout your project
Processing Note
Apply resin to the substrate first, lay the cloth, then work resin through from the top and consolidate with a ribbed roller. Because this is a heavy fabric, rushing wet-out is the most common cause of dry spots and laminate failure.

FAQs
Is this 1200gsm Biaxial Fibreglass Fabric the same as the per metre listing? Yes — identical specification. The full roll simply offers better value per metre for ongoing or production work.
Can I get a sample before committing to a full roll? Yes — order a metre from our per metre listing first before purchasing the roll.
