What are the best fastening methods for assembling WPC outdoor seating to avoid material stress?

When assembling WPC (Wood Plastic Composite) outdoor seating, choosing the right fastening methods is crucial to prevent material stress and ensure longevity. Here are the best techniques:

1. Stainless Steel Screws: Use corrosion-resistant stainless steel screws to avoid rust and reduce stress on WPC material. Pre-drill holes to prevent splitting.

2. Hidden Fasteners: Opt for concealed clips or brackets to minimize visible damage and distribute pressure evenly across the seating structure.

3. Flexible Adhesives: High-quality outdoor adhesives can bond WPC components without creating rigid stress points, ideal for joints and seams.

4. Expansion Gaps: Leave small gaps between panels to accommodate thermal expansion, reducing stress caused by temperature changes.

5. Rubber Washers: Place rubber washers under screw heads to absorb vibrations and prevent cracking under pressure.

By following these methods, you can assemble WPC outdoor seating securely while avoiding material stress and ensuring durability in all weather conditions.
