About Square Bars

Square bars are long, solid, extruded metal products with a cross section featuring a perfectly square cross-section. This can be contrasted with flat bars, which are rectangular in shape, and round bars, which are circular. They may be produced to a range of sizes but must have equal widths and heights.

At Polished Metals, our broad inventory includes a wide selection of stainless steel square bar products of varied sizes. What’s more, our specialized equipment can add nearly any finish to these products according to a project’s precise needs and specifications. You can learn more about the finishes we offer here.

Common Varieties

Square bars are available in many varieties of stainless steel. The most common by far, however, are 304 stainless steel and 316 stainless steel.

304 Stainless Steel Square Bar

304 stainless steel is one of the most widely used alloys, providing good corrosion resistance with excellent forming characteristics. This variety has many uses as a polished metal, and square bars in 304 stainless steel are highly versatile in their utility as a result.

316 Stainless Steel Square Bar

Compared to 304 stainless steel, 316 includes a higher nickel content as well as added molybdenum, making this variety much more corrosion resistant than 304. 316 stainless steel is commonly seen in harsher environments, such as in situations where exposure to corrosive chemicals or to brine solutions is expected (such as marine environments).

Industry Use Cases

Square bars have nearly endless utility across numerous industries, and stainless steel is one of the most frequently used metals worldwide. As a result, stainless steel flat bar can be seen in a wide range of situations, including:

Architecture and design projects, including interior design
Engineering and construction, such as for structural supports
Elevators, escalators, and stairways, typically used as a support, for trim, or for safety features such as railings
Manufacturing of all kinds, particularly automobiles and machinery where square bars may be used as axles, braces, or for frames
Food and beverage or pharmaceutical industries, especially 316 stainless steel, with its greater corrosion resistance

Why Stainless Steel?

Stainless steel is one of the strongest commonly used materials in the world, outperformed only by much rarer and more expensive metals such as tungsten in terms of sheer strength. This makes stainless steel an ideal choice for just about any structural purpose, and square bars are an ideal product to use as a support due to its right angles, making it highly space efficient.

In addition to its strength, all stainless steel varieties are very corrosion resistant, less likely to warp, and take well to most metal finishes, making polished stainless steel a visually versatile material as well.

“Polished Metals has been a Preferred Vendor of ours for over a decade. Our corporate philosophy dictates that we have Alternate or Secondary Supplier for all product, with the exception of #8 Mirror Polished Stainless Steel. We’ve tried to qualify other suppliers to no avail, as none of them can compete in any of the critical categories. The Customer Support provided by Bob Gunther cannot be replicated, pricing is fair, delivery is always on-time and quality is fantastic. As the Corporate Purchasing Manager for the last 7 years, not once have I had a negative experience with Polished Metals. I can’t say enough good things about them.”
