We can manufacture outdoor steel trolleys with PVC cover, 100% waterproof. This trolley is provided with a closing cover (closing curtain) which slides on steel rollers in a “C” channel. The cover closes the trolley with both velcro and plastic or steel locking pins. If the trolleys are used mainly outdoors and the rolling surface is not smooth, we recommend our customers to go for spring loaded castors which absorb the mechanical shocks during transport.
