As **Cangzhou Haoran Sports Equipment Co., Ltd. (Made in Hebei, China)**, our outdoor interlocking suspended floor tiles are professionally engineered to solve thermal expansion & contraction issues:

1. **Reserved expansion gaps** We design scientific splicing reserved gaps between each tile, effectively absorbing thermal expansion and cold contraction caused by temperature changes. 2. **Modified raw material formula** Adopt reinforced anti-aging PP virgin material, low thermal expansion coefficient, not easy to deform. 3. **Anti-arched structural design** Hollow supporting bottom + integrated locking buckle structure, greatly avoid upturning, arching, warping or loosening. Under normal outdoor temperature differences, **no obvious arching, bulging or separation** occurs, stable for long-year outdoor use.
