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

Outdoor furniture exposed to spruce tree sap requires specialized protection to maintain durability and aesthetics. ODM manufacturers employ high-quality materials like powder-coated metals, UV-resistant plastics, and treated hardwoods to prevent sap adhesion. Advanced protective coatings, such as polyurethane or epoxy finishes, create a non-porous barrier against sap penetration. Additionally, manufacturers conduct rigorous testing, including exposure to simulated sap and harsh weather conditions, to ensure long-term resistance. By integrating these techniques, ODM producers deliver outdoor furniture that withstands spruce tree sap while retaining functionality and visual appeal.
