Bending strength is an important indicator for evaluating the performance of WPC flooring, determining the stability and durability of the flooring under external loads. Different types of WPC flooring (hollow type, solid type, and open type) exhibit significant differences in bending strength due to their structural variations. Here, we will analyze the bending strength of these three types of WPC flooring.
| Type | Solid WPC Flooring | Hollow WPC Flooring | Open WPC Flooring |
|---|---|---|---|
 |
 |
 |
|
| Cross-Section Structure | Completely solid, no holes | Round/square hole tunnels inside | Bottom semicircular holes or grooves |
| Bending Structure | Excellent | Optimal | Worst |
| Advantages | High strength, good weather resistance, long service life | Lightweight, low cost, high bending strength, suitable for large area installation | Good drainage (semi-circular holes form drainage channels), small expansion deformation, relatively low cost |
| Installation Requirements | Heavy weight, high cost, noticeable thermal expansion and contraction, installation gaps need to be reserved | Prone to internal water accumulation and expansion, requiring end sealing or additional drainage holes; thin surface, prone to cracking with long-term wear | Low bending strength, requiring an additional support to enhance stability. |
| Applicable Places | High foot traffic public places (squares, parks) | Home courtyards, terraces | Humid environments (beside swimming pools, under awnings) |
The three types of flooring each have their practical value and space in different applications, and specific needs should be considered comprehensively when making a selection.
