Leveling Washers for I-Beams
Mounted on an I-Beam
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Black-oxide iron washers have a matte-black finish that prevents corrosion in dry environments.
Hot-dipped galvanized iron washers are corrosion resistant in wet environments.
Aluminum washers are lightweight and corrosion resistant in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Metric Leveling Washers for I-Beams
Mounted on an I-Beam
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Zinc-plated steel washers are coated for corrosion resistance in wet environments.
Hot-dipped galvanized steel washers are ten times more corrosion resistant than zinc-plated washers.
18-8 stainless steel washers are the most corrosion-resistant option.
