Description
Steel square tubing is an excellent candidate for most processing. Square steel tubing is available in A500 grade B or A513. Steel square tubes have a non-coated, semi-smooth grey finish. Mechanical/structural steel square tubing “wall thickness” has a tolerance of +/- 10%. Common applications include trailers, frames, shelves, and structural support. ASTM A500 is the standards specification for cold-formed welded and seamless carbon steel structural tubing in rounds and shapes. ASTM A513 is the standard specification for electric-resistance-welded carbon and alloy steel mechanical tubing.
