What thermal expansion compensation methods are built into WPC outdoor bar stools?

WPC (Wood-Plastic Composite) outdoor bar stools are designed to withstand varying weather conditions, including temperature fluctuations that cause thermal expansion. To address this, manufacturers incorporate several compensation methods:

1. Expansion Gaps: Small gaps are left between components to allow for natural material expansion without warping or cracking.

2. Flexible Joints: Some designs use flexible connectors or fasteners that adjust as the material expands or contracts.

3. Slotted Screw Holes: Screws are placed in elongated holes, enabling slight movement as the WPC expands or contracts.

4. Material Blending: Advanced WPC formulations include additives to minimize expansion rates while maintaining durability.

These features ensure long-term stability and comfort, making WPC bar stools a reliable choice for outdoor settings.
