What’s The Benefit Of Chipboard Levels?

Chipboard levels offer a cost-effective, strong, and reliable surface for general garage and workshop storage. They provide excellent load-bearing capacity (up to 400kg UDL* per shelf in this unit) and are easy to replace if damaged. While not suitable for environments with high humidity or frequent spills, they are perfectly durable for storing heavy tools, equipment, and parts in typical garage conditions.

Where Can This Heavy-Duty Garage Shelving Unit Be Used?

The BiG400 Heavy-Duty Garage Shelving Kit is ideal for environments requiring substantial storage capacity and durability. Beyond its primary use in garages for tools and equipment, it's perfectly suited for workshops, sheds, stockrooms, and even small commercial storage areas where its 400kg UDL* per shelf capacity can handle heavy, bulky, or dense items safely.
