Drip trays made of non-toxic polyethylene, stabilised and therefore resistant to UV rays, formed via rotational moulding, with self-supporting structure, reinforced and therefore resistant to impacts and chemicals also equipped with a support surface made of removable galvanised steel mesh to allow internal cleaning. The trays can be stacked when empty and transported using a forklift. Drum holder trays made of polyethylene are the most cost-effective means of protecting the environment and complying with the strictest environmental regulations.
