MetroMax Polymer Stock Carts

MetroMax Polymer Carts, Metro I, 4, and Q Series Lab and Industrial Carts

Metro MetroMax Polymer Carts are crafted for lifelong durability, blending the robustness of steel with a lifetime warranty against rust and corrosion on the MetroMax I line. Shelves are made from advanced polymers and reinforced with Type 304 stainless steel corners, ensuring exceptional stability and strength.

The MetroMax Q shelving system includes removable polymer shelf mats and epoxy-coated frames and posts, offering a durable, easy-to-clean alternative to traditional epoxy-coated wire shelving, especially for wet environments. The 20-year warranty covers shelf frames and posts against rust and corrosion. MetroMax 4 rounds out the lineup as a lifetime-warrantied, open grid option for facilities that need reliable corrosion resistance at a more accessible price point.
