This wheelbarrow from the Walsall Wheelbarrow Company has a super heavy duty pan that is made from HDPE. HDPE stands for High Density PolyEthylene, which has a linear polymer structure. This gives it an excellent strength to weight ratio, giving you an easy to handle barrow that is strong enough to deal with heavy impacts. Another advantage of HDPE is that it absorbs much of the impact and reduces noise and vibration when loading.
