Stainless Steel Flat Bar

Stainless Steel Flat Bar

Stainless steel flat bar is an ideal material for many different design, architectural, and construction applications. These custom-cut steel bars resist corrosion and can serve as attractive accents for building projects. We polish our metals in-house and offer a superior array of finish options to suit any build or design.

Stainless Steel Flat Bar in Custom Finishes

Stainless flat bar is cut from a plate of steel for a strong and corrosion-resistant multipurpose metal product. It is an important building component in the architecture, construction, engineering, marine, and food service industries.

Stainless flat bar forms durable and attractive handrails, frames, supports, and design accents. This metal’s modern aesthetic pairs beautifully with glass.

304 and 316 Stainless Steel

The two most common grades of stainless steel for flat bar are 304 and 316. We offer both 304 & 316 polished flat bar to see your project through from start to finish.

Most stainless flat bar is made of 304 stainless steel. This grade is durable, corrosion-resistant, and strong relative to its weight.

For more demanding applications, 316 stainless steel contains the rare metal molybdenum. The resulting alloy is extremely corrosion-resistant and can also resist salt and chlorine, making it a superior choice for marine buildings, pools, and water features.

#8 Mirror, 8 Super Mirror, and High Polish Super 8

Achieve a mirror-like reflective shine with our specialized high-polish stainless steel. This finish is polished directionally, is virtually free of grit lines, and can be easily blended for fabrication.

Grain Finishes

Excellence in architectural design comes down to the details. Our metalwork polishing options allow you to choose an exact grain pattern for your project. We offer the following grain finishes in stainless steel flat bar:

  • #3 Satin
  • #4 Satin
  • #6 Satin
  • #6 Satin long grain (hairline)
  • Grits 180 or 240
  • 20RA-40RA
  • Random orbital or non-directional grain
  • Non-directional satin (angel hair)

We can simulate a continuous grain along a piece of stainless steel with a #6 satin long grain finish. The angel hair finish is a very fine-grain non-directional grain pattern.
