Fiber glass biaxial fabric

Buyers must focus on the Areal Weight (GSM), typically ranging from 200g/m² to 1200g/m², and the Stitching Pattern (usually polyester yarn). Ensure the Fiber Orientation is precisely 0°/90° or ±45° depending on your structural needs. For high-performance applications, verify the Sizing Type (e.g., Silane) to ensure compatibility with specific resin systems like Epoxy, Polyester, or Vinyl Ester.

To ensure structural safety, prioritize suppliers with ISO 9001 for quality management. For marine or wind energy sectors, look for DNV-GL or Lloyd’s Register certifications. Additionally, ensure the product meets ASTM D5035 for breaking force and elongation properties, and check for REACH/RoHS compliance if exporting to the European market.

Biaxial fabric is non-crimp, meaning the fibers stay straight rather than interlacing. This results in higher mechanical strength, better resin-to-glass ratios, and improved fatigue resistance. It allows for thinner, lighter laminates compared to traditional woven roving, making it the preferred choice for aerospace, automotive, and high-end marine hulls.

It is widely used in Wind Turbine Blades for torsional stiffness, Boat Hulls and Decks for impact resistance, and Automotive Body Panels. It is also ideal for Sports Equipment (like skis and surfboards) and Infrastructure Repair where high strength-to-weight ratios are critical.

The biggest risks include Moisture Absorption during sea transit and Physical Deformation due to improper stacking. Ensure the supplier uses vacuum-sealed plastic packaging and sturdy palletization with edge protectors. Always request a Pre-Shipment Inspection (PSI) to verify the roll length and weight match the packing list.

Focus on Volume-Based Pricing; discounts of 5-10% are common when moving from LCL (Less than Container Load) to Full Container Loads (FCL). Negotiate for Free Samples (usually 1-2 meters) to test resin infusion compatibility. For long-term partnerships, aim for Net 30 payment terms after a successful initial transaction via Made-in-China.com's secured payment services.

Fiberglass is heavy and relatively fragile. Use FOB (Free On Board) terms if you have a reliable forwarder to control costs, or CIF (Cost, Insurance, and Freight) for convenience. Ensure the HS Code (typically 7019) is correctly classified to avoid customs delays or incorrect duty applications. Always include Desiccants inside the container to prevent 'glass rot' or sizing degradation caused by humidity.

Look for the 'Audited Supplier' badge, which indicates the factory has been verified by third-party agencies like SGS or Bureau Veritas. Check their Export Experience—suppliers who regularly ship to the US or EU are more likely to understand strict quality and packaging standards.
