Fiberglass cloth mesh

Buyers must prioritize weight (gsm), mesh size (e.g., 4x4mm, 5x5mm), and tensile strength. For EIFS (Exterior Insulation and Finish Systems), a weight of 145g/m² to 160g/m² is standard. Ensure the mesh is treated with an alkali-resistant polymer coating, as untreated glass fiber will degrade when embedded in cement-based mortars.

Request alkali resistance test reports (retained strength should be >50% after 28 days in alkaline solution). Ensure the product meets ETAG 004 standards for European markets or ASTM D579 for North America. Look for suppliers on Made-in-China.com who hold ISO 9001 certification to ensure consistent weaving density and coating quality.

Lightweight mesh (45g-75g) is ideal for internal wall plastering to prevent hairline cracks. Medium-weight mesh (145g-160g) is the industry standard for external wall insulation (EIFS). Heavy-duty mesh (above 300g) is required for high-impact zones or stone reinforcement to provide structural integrity.

The coating is critical; Acrylic acid copolymer liquid is the premium choice for alkali resistance. It ensures the mesh remains flexible for easy installation while protecting the glass fibers from the corrosive nature of cement. Avoid 'soft' meshes that lack sufficient resin, as they will tear easily during application.

The primary risk is alkali-resistance failure, which isn't visible to the naked eye but causes structural cracks later. Another risk is short-rolling, where the actual length is less than the stated 50m or 100m. Always use Made-in-China.com's Secured Trading services and request a pre-shipment inspection to verify roll weight and length.

Fiberglass mesh is a volume-driven commodity. Bulk discounts of 10-15% are common for full container loads (FCL). If you are a small buyer, look for suppliers with low MOQs (e.g., 50-100 rolls) on Made-in-China.com. Negotiate based on total resin content percentage, as this is a major cost driver.

Fiberglass mesh rolls are susceptible to edge deformation. Ensure the supplier uses shrink-wrap for individual rolls and sturdy cardboard tubes to prevent crushing. For shipping to regions with high humidity, specify palletization with moisture-proof film to prevent the coating from becoming tacky during transit.

Verify if your country has anti-dumping duties on Chinese fiberglass (e.g., the EU has specific regulations). Work with Audited Suppliers on Made-in-China.com who can provide a Certificate of Origin (CO) to help you benefit from preferential trade agreements and ensure a transparent payment process through escrow-based systems.
