Thickened cold-rolled steel plate is used as the main material, which is stronger and more durable than ordinary steel plate, and can withstand heavy objects and bumps and wear in daily use. The three-layer powder coating treatment not only improves the appearance and texture of the tool box, but also greatly enhances its anti-corrosion and anti-rust performance. Whether it is a humid warehouse or a harsh outdoor environment, it can remain as new for a long time. This 7-drawer and 6-drawer rolling tool box has become an indispensable tool management assistant for professionals and home users with its excellent material, reasonable design, convenient mobility and wide applicability.
