How to calculate SS Tube weight
Square tube weight per metre (kg) = 4 × WT × (Side − WT) × 0.00793. A 40 × 40 × 1.5 mm SS 304 square tube weighs about 1.83 kg/m.
Stainless Steel Tube — FAQs
What is the difference between a pipe and a tube?
Pipes are specified by nominal bore and schedule (for carrying fluids). Tubes are specified by exact outside diameter and wall thickness, and are used where precision matters, or for structures.
Do you supply polished square tubes?
Yes. Square and rectangular tubes are available in satin, mirror and hairline polish in 304 and 202.
How do I calculate the weight of an SS square tube?
Weight per metre = 4 × wall × (side − wall) × 0.00793 kg. Use our weight calculator for square, rectangular and round tubes.
