304 Stainless Steel Square Tube Supplier

When your assembly requires a corrosion-resistant structural component that holds dimensional tolerances across production runs, the material and the supplier both matter. As a 304 stainless steel square tube supplier serving OEMs throughout Texas, Texas Alloys & Tool Co. maintains consistent inventory, multiple wall thickness options, and the technical knowledge to help you source the right product the first time.

304 Stainless Steel Square Tube: What You're Getting

304 stainless steel is the most widely used austenitic stainless alloy. It contains 18% chromium and 8% nickel, which gives it strong corrosion resistance in most environments — including exposure to moisture, mild chemicals, and oxidizing conditions. It is non-magnetic in its annealed state, easy to weld and fabricate, and maintains its surface finish well in demanding applications.

Square tube made from 304 stainless steel takes those properties and adds a hollow, closed structural profile with four equal sides. The result is a component that handles bending loads in multiple directions, resists torsion, and integrates cleanly into framed assemblies, enclosures, and equipment structures.

Texas Alloys stocks 304 stainless steel square tube in a range of outside dimensions and wall thicknesses to support your bill of materials without requiring custom ordering on standard sizes. Our specialty metal products inventory is maintained specifically to serve OEMs who need consistent availability across production cycles.

Wall Thickness and Size Options

Stainless steel square tube is specified by outside dimension and wall thickness. A thicker wall adds strength and load capacity; a thinner wall reduces weight and material cost. Selecting the right combination depends on the structural requirements of your application.

Texas Alloys stocks 304 stainless steel square tube in outside dimensions ranging from 1/2" through 4", with wall thicknesses from 14 gauge through 3/16". If your application calls for a size not in our standard inventory, our sales team can assist with sourcing or direct you to the closest available substitute.

Common OEM Applications

304 stainless steel square tube is used across a wide range of industrial equipment and manufactured assemblies. OEMs specify it when the application demands both structural integrity and corrosion resistance:

For applications where corrosion resistance is the primary driver, 304 is the standard starting point. When exposure to chlorides, saltwater, or harsh chemicals is a factor, our team can review whether 316 stainless steel tube would be a better fit for your specs.

Why OEMs Source Stainless Steel Square Tube from Texas Alloys

OEM production runs don't have room for material inconsistency. When you spec a component at the design stage, you need the same material available as your production volume scales up. Texas Alloys has supplied metals to OEMs and industrial manufacturers throughout Texas since 1995. Our inventory is maintained to support ongoing orders, not just one-time requests.

Our team is familiar with the specifications and tolerances that OEM buyers require. When you need to verify chemistry, surface finish, or dimensional accuracy before placing a volume order, we can support that process. We also supply a full range of carbon steel structural products for OEM applications where corrosion resistance is not a requirement and cost reduction is the priority, so you can compare materials and make the call that fits your design.
