Buyers should focus on alkali resistance, as this is critical for construction applications like EIFS (Exterior Insulation and Finish Systems). Ensure the mesh has a weight per unit area (gsm) that matches the project requirements—typically 145g/m² to 160g/m² for standard wall reinforcement. Additionally, verify the tensile strength (both warp and weft) to ensure it can withstand structural stress without tearing.

For the European market, look for ETAG 004 certification, which is the gold standard for external thermal insulation composite systems. In the US, compliance with ASTM D5035 for breaking force and elongation is vital. Always request a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) from the manufacturer to verify chemical composition and safety.

The quality of the acrylic acid copolymer liquid coating is paramount. A high-quality coating ensures the fiberglass remains stable in alkaline environments (like cement). Without proper coating, the glass fibers will decompose over time, leading to structural failure. Ensure the supplier uses a coating content of at least 15-20% of the total weight for maximum durability.

Fiberglass mesh is primarily used for wall reinforcement, roof waterproofing, and marble backing. Finer mesh (e.g., 4x4mm) is ideal for internal plastering, while heavier, wider mesh is used for external stone reinforcement or road surfacing. For specialized industrial use, PTFE-coated fiber mesh is preferred for high-temperature conveyor belts.

Always request a pre-shipment inspection (PSI) by a third-party agency like SGS or Intertek. Specifically, ask them to perform an alkali-resistance test (soaking the mesh in a NaOH solution for 28 days) to ensure the strength retention rate is above 50%. Utilizing Made-in-China.com's Secured Trading Service can also protect your payment until the goods are verified.

Negotiate based on total volume and container utilization. Since fiber mesh is lightweight but bulky, shipping costs can be high. Ask for vacuum packaging to increase the number of rolls per container, which can reduce your landed cost per unit by 10-15%. Also, discuss OEM branding early, as many top-tier suppliers offer custom label printing on the mesh itself for large orders.

Fiber mesh rolls are susceptible to deformation if stacked too high. Ensure the contract specifies vertical palletizing with protective corner boards. For shipping to regions with high humidity, ensure the use of desiccants inside the container to prevent the cardboard cores from softening, which can lead to collapsed rolls and difficult unloading.

Verify the supplier's Business License and Export Qualification on Made-in-China.com. Ensure the Harmonized System (HS) Code used is 7019.61 (for closed woven fabrics of glass fibers), as incorrect classification can lead to customs delays or unexpected anti-dumping duties in certain regions like the EU or Turkey.
