Stainless Steel Finishes

As produced, stainless steel products typically display discoloration caused by the introduction of heat during welding, cutting or grinding processes. If appearance is important to your application, consideration should be given to secondary cleaning or electro-polishing.

Mill Finish

Products will display discoloration from welding, cutting and grinding. Satisfactory for industrial or process applications where appearance is not a consideration.

Commercial Clean

A uniform, matte finish is achieved by abrasive blasting followed by passivation to remove manufacturing contaminants.

Electro-Polished

A bright, chrome-like appearance achieved by immersion in chemicals that clean and “polish” the base metal.


Steel Gratings are manufactured by cold-press riveting straight bearing bars to crimped rectangular flat bars. Our oldest products, riveted gratings offer superior resistance to impact, fatigue and repetitive loads.

Materials

Steel Gratings are available in carbon steel, 6000 series aluminum and 300 series stainless steels. These products are manufactured with bearing bars spaced either 1-1/8" or 3/4" apart and the standard rivet spacing is 7 inches on center. Optional close rivet spacing of 3-1/2" on center is also available.

Serrated Surface

The standard method of manufacturing serrated Steel Gratings is to serrate the crimped cross member. When assembled, these cross members are raised slightly above the top surface of the bearing bars to provide a superior unidirectional slip-resistant surface. If your application is particularly prone to unsafe walking conditions, consider specifying "100% Serrated" grating where both the bearing bars and cross members are provided with serrations.
