When sourcing sofa furniture strips (often referring to decorative nail strips, webbing, or edge trim), material durability is paramount. For decorative nail strips, ensure they are made of high-quality steel or brass with electroplated finishes to prevent rust and oxidation. For elastic webbing strips, look for a high percentage of natural rubber (over 60%) combined with high-tenacity polyester yarn to ensure long-term tension retention. If you are sourcing PVC or leather edge strips, verify the UV resistance and flexibility to prevent cracking over time.
