Artificial grass

Selecting the correct specifications depends entirely on the intended use. For high-traffic sports fields, a pile height of 40mm-60mm with high-density polyethylene fibers is required for shock absorption. For residential landscaping, a height of 30mm-40mm provides a lush, natural look. Density (stitches per square meter) is critical; higher density (e.g., 18,900+ stitches/m²) ensures better resilience and a more premium feel, preventing the grass from looking 'flat' over time.

B2B buyers must prioritize UV stability and chemical safety. Ensure the product has passed UV resistance testing (e.g., 3000+ hours) to prevent fading and brittleness. Crucially, verify that the grass is lead-free and non-toxic, complying with REACH, RoHS, or EN71-3 standards, especially for school or playground installations. For indoor or commercial use, a Fire Retardant Class B1 or B2 certification is often a mandatory legal requirement.

The backing material is the foundation of durability. Look for PP+Net+SBR Latex or PU (Polyurethane) backing; PU is superior for moisture resistance and prevents the grass blades from pulling out. Ensure the product features perforated drainage holes (typically every 10-15cm) with a drainage capacity of at least 60 liters/minute/m² to prevent waterlogging and mold growth during rainy seasons.

Examine the blade shape (C-shape, U-shape, or W-shape); these shapes offer better structural memory and heat dissipation than flat blades. The Dtex (linear density) indicates the yarn weight; a higher Dtex (e.g., 8000-12000) signifies thicker, more durable blades. Additionally, look for multi-tone color blending (e.g., 4-color grass with green and brown thatch) to achieve a realistic aesthetic that mimics natural soil and dead grass layers.

The biggest risks are color batch inconsistency and creasing during transit. Always request a production sample from the current batch before shipping. To mitigate creasing, ensure the supplier uses heavy-duty cardboard tubes inside the rolls and wraps them in UV-stabilized plastic film. For large orders, use third-party inspections to verify the roll length and stitch count match the Proforma Invoice.

Focus on the Total Landed Cost rather than just the unit price. Negotiate for volume-based discounts (typically 5-10% for full container loads) and ask for free installation accessories like jointing tape or U-pins. If you are a long-term buyer, negotiate for OEM branding on the backing and customized roll widths (e.g., 2m or 4m) to reduce local cutting waste.

Artificial grass is bulky and heavy, making Sea Freight (FCL - Full Container Load) the only economically viable option for large quantities. To optimize shipping costs, calculate the container utilization rate; a 40HC container can typically hold 7,000-9,000 sqm depending on pile height. Ensure the supplier provides a detailed packing list and uses forklift-friendly loading to prevent damage to the roll ends during unloading at your warehouse.

Utilize Secured Trading services on Made-in-China.com to protect your payment until the goods are shipped. Insist on a warranty certificate (typically 5-8 years) that explicitly covers UV degradation and fiber loss. For high-value projects, hire an inspector to perform a Loading Supervision to ensure the quantity is correct and the rolls are not crushed by heavy items placed on top.
