Steel Rectangular Bar Stock Sizes: Width, Height & Gauge Comparison

Steel rectangular bar stock sizes play a pivotal role in various industries, including manufacturing, construction, and many others. This is due to their versatility, strength, and the wide range of sizes available. Let's delve into the world of steel bar stock sizes, exploring their types, sizes, and applications.

Before we dive into the specifics, it's essential to understand that steel bar stock sizes are typically measured in millimeters or inches. The size of a bar is determined by its cross-section, which can vary in width, thickness, or diameter, depending on the bar's shape.

Standard Sizes of Steel Rectangular Bar Stock

Steel rectangular bar stock, also known as flats, is available in a wide range of standard sizes. These bars are typically measured in millimeters and can vary in width and thickness. Some of the most common sizes include:

Widths: 20mm, 25mm, 30mm, 35mm, 40mm, 50mm, 60mm, 75mm, 90mm, 100mm, 120mm, 150mm, 175mm, 200mm, 225mm, and 250mm.

Thicknesses: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 80mm, and 100mm.

Widths of Steel Rectangular Bar Stock

Widths of steel rectangular bar stock can greatly influence the application of the bar. Narrower widths are typically used for machine frames, gear teeth, and other components that require precise drilling and milling. On the other hand, wider widths are often used in construction, for applications like formwork, reinforcing, and support structures.

It's worth noting that some widths may not be available in all thickness options. Always check with your supplier to ensure the specific size you need is available.

Thicknesses of Steel Rectangular Bar Stock

The thickness of steel rectangular bar stock can impact its strength and durability. Thinner bars are generally more flexible and easier to work with, making them suitable for applications like handrails, fencing, and decorative items. Thicker bars, however, offer greater strength and are used in heavy-duty construction, such as beams, girders, and crane runway beams.

Moreover, the thickness can also affect the bar's machinability. Thicker bars may require more substantial cutting and forming equipment, while thinner bars can be machined using standard tools.
