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

Outdoor furniture exposed to redwood trees faces unique challenges, particularly from sap, which can damage surfaces over time. ODM manufacturers address this by selecting durable materials like powder-coated aluminum, teak, or high-density polyethylene (HDPE) that naturally resist sap adhesion. Advanced weatherproof coatings are applied to create a protective barrier, preventing sap from penetrating the material. Additionally, rigorous testing simulates long-term exposure to ensure longevity. By combining high-quality materials with innovative treatments, ODM manufacturers deliver outdoor furniture that withstands redwood sap while maintaining aesthetic appeal and functionality.
