Additional steel processing services

cutting Service

For parts that require extremely high wear resistance, we use abrasive waterjet cutting to maintain hardness throughout the part without creating a heat-affected zone. For thicker plates up to 200mm, we use precisely controlled CNC oxy-fuel cutting. For products requiring high cut quality and dimensional tolerances, we use high-definition underwater plasma cutting to maximize plate performance in abrasive applications.

frequently asked questions

Is square steel tubing stronger than round?

What grade of steel is square tubing?

A cylindrical pipe is stronger than a square pipe because it has no weak points at the corners and has a consistent strength along its inner and outer surfaces. It is also more resistant to bending and twisting under weight.

Square steel pipes are available in A500 Grade B or A513 Grade. Square steel pipe has an uncoated, semi-smooth gray finish. Mechanical/structural steel square tubing has a tolerance of +/- 10% on “wall thickness”.

Common applications include trailers, car frames, racks and structural supports. ASTM A500 is a standard specification for round and profile cold-formed welded seamless carbon steel structural tubing.

ASTM A513 is a standard specification for electric resistance welded carbon and alloy steel mechanical tubing.
