Square tube specific weight: weight per linear meter
A profile tube is steel rolled metal whose cross-sectional shape differs from a round one. The section profile can be oval, rectangular, square or ribbed. Profile tubes are made by cold or hot rolling of steel blanks. After passing through the rolling mill, the longitudinal seam is welded, and additional processing removes surface irregularities and internal mechanical stresses.
Depending on production technology, profile tubes can be:
- made of carbon and low-alloy steel,
- aluminum,
- stainless,
- galvanized.
Galvanizing technology is used in the production of rolled metal resistant to environmental exposure and for visually attractive profiles of open metal structures. Galvanizing increases the service life of rolled metal, and such a coating has high anti-corrosion properties.
The advantages of use are:
- reduced metal consumption and, accordingly, reduced building weight due to the low weight of profile tubes,
- simpler and cheaper installation of lightweight metal structures,
- modern appearance,
- low fire hazard,
- high strength and reliability when material quality and installation conditions are observed.
It is also worth noting that profile rolled metal is much more convenient for transportation and storage than round pipe.
Weight of profile tubes
Profile rolled metal is used in the construction of building frames, various metal structures and automotive production, that is, under increased mechanical and vibration loads.
Correct calculation of the quantity and mass of rolled metal plays an important role. When buying material at wholesale warehouses, nobody measures kilometers of pipe. Therefore, kilograms are used as the unit of measurement for rolled metal. If you know the weight of a square profile tube in 1 linear meter, it is easy to calculate the weight of the entire length.
The size of profile tubes is determined by the length of the section side. For example, a square tube with a 20 mm side is marked as 20x20, and with a 40 mm side as 40x40.
The profile size is chosen based on technical tasks. For simple structures such as furniture, playground elements, decorative fencing and similar items, products with a 20x20 section can be used. For massive structures, for example advertising boards, a profile designed for higher loads is needed.
The wall thickness of the profile tube also affects its mass. If you need to know the weight of square tubes as accurately as possible, the assortment table is the best option. You can also use special rolled metal weight calculators. However, deviations from theoretical values may be within 12% in either direction. It all depends on steel quality and wall thickness uniformity.

If you have a 100x100 square tube, its weight can be determined by the formula:
Mp = S * 2 * (A + B) * p,
where A and B are wall lengths,
S is wall thickness,
p is material density,
Mp is the mass of 1 linear meter.
A 20x20 square tube has a weight of 1 meter with a wall thickness of 1 mm equal to 0.583 kg, and with 2 mm equal to 1.075 kg.
Frequently Asked Questions
Can the density of square tube, weight of 1 m of square tube be used for precise calculations?
The density and weight values for square tube, weight of 1 m of square tube in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of square tube, weight of 1 m of square tube differ from the table?
The actual weight of square tube, weight of 1 m of square tube depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of square tube, weight of 1 m of square tube from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of square tube, weight of 1 m of square tube is given in kg/m³ and the volume is in m³, the result will be in kilograms.
