Light Duty Heavy Duty Steel Grating 1-1/4" x 1/4" To 6" x 1/2"
Carbon Steel bar grating is a nice choice when your project
requires a strong material and you are not going to expose the
metal grating to an expressly corrosive environment. Choose from
plain or serrated bar grating surfaces, galvanized, bare steel or
painted finshes. Bar grating is available as Light or Heavy Duty
Welded grating. Great for industrial steel flooring and metal
grates.
Heavy Duty bar gratingranges in size from 1-1/4" x 1/4" to 6" x 1/2".
