Unistrut General Fittings
Fittings, unless noted, are made from hot-rolled, pickled and oiled steel plates, strip or coil, and conform to ASTM specifications A575, A576, A635, or A36. The fitting steel also meets the physical requirements of ASTM A1011 SS GR 33. The pickling of steel produces a smooth surface free from scale. Many fittings are also available in stainless steel, aluminum and fiberglass.
