Rack steel refers to high-grade steel specifically designed for manufacturing storage racks, valued for its exceptional strength, durability, and load-bearing capacity. This material is engineered to withstand heavy weights without bending or warping, making it ideal for industrial, commercial, and residential storage systems. It comes in various gauges (thicknesses), with thicker gauges used for heavy-duty racks in warehouses and thinner gauges for lighter-duty shelving in garages or retail spaces. Key properties include resistance to corrosion (often enhanced by galvanization or powder coating), weldability for sturdy joins, and flexibility in fabrication—allowing for custom lengths and shapes. Rack steel is the backbone of pallet racks, shelving units, and cantilever racks, supporting everything from boxes and tools to large machinery components. Our rack steel meets industry standards for strength and safety, with clear load capacity guidelines to ensure proper use. It is sourced from reputable mills and tested for consistency.
