How do ODM manufacturers ensure the resistance of outdoor furniture to sap from willow trees?

ODM manufacturers employ several strategies to ensure outdoor furniture withstands willow tree sap, a common challenge in outdoor settings. First, they select durable materials like powder-coated aluminum, teak, or high-density polyethylene (HDPE) that naturally resist sap adhesion. Second, advanced weatherproof coatings are applied to create a protective barrier, preventing sap from penetrating the surface. Additionally, manufacturers conduct rigorous testing, exposing furniture to simulated sap and environmental conditions to verify resistance. Finally, easy-to-clean designs with smooth surfaces are prioritized to simplify maintenance. These measures ensure longevity and aesthetic appeal, even in sap-prone areas.
