Metal Bar Grating
Metal Bar Grating is the workhorse of the industrial flooring market and has served industry for decades. Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration.
The high percentage of open area makes bar grating nearly maintenance free and all products are fully recyclable.
Manufactured by assembling a series of equally spaced metal bars to connecting cross members, bar grating is available in three popular materials; Mild carbon steel, 6000 series aluminum and 300 series stainless steels. Additionally, Interstate Gratings can produce gratings constructed with other specialty metal alloys.
Methods of Manufacturing
Welded Grating
Economical design ideal for most industrial applications.
Manufactured by welding the bearing bar/cross bar intersection, typically with automated forge welding equipment.
Available in carbon steel and stainless steel.
Dovetail Pressure
Locked Grating
Assembled by inserting pre-punched bearing and cross bars into an "eggcrate" configuration and deforming the cross bars under intense hydraulic pressure.
Available in all materials and ideal for many architectural and ornamental applications.
Swage Locked Grating
Popular for the manufacture of aluminum, stainless steel and close mesh gratings.
Cross bars are inserted into pre-punched holes in the bearing bars and then hydraulically deformed to lock the bars in place.
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.
