The specific production of

Square tube

Square tubes are classified by purpose: square tubes for decoration, square tubes for machine tool equipment, square tubes for mechanical industry, square tubes for chemical industry, square tubes for steel structure, square tubes for shipbuilding, square tubes for automobile, square tubes for steel beams and columns, and square tubes for special purposes.

Wall thickness classification

Rectangular tubes are classified according to wall thickness: extra thick walled rectangular tubes, thick walled rectangular tubes and thin-walled rectangular tubes.


Application fields: it is widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railways, highway guardrails, container skeleton, furniture, decoration and steel structure.

It is used for engineering construction, glass curtain wall, door and window decoration, steel structure, guardrail, machinery manufacturing, automobile manufacturing, household appliance manufacturing, shipbuilding, container manufacturing, electric power, agricultural construction, agricultural greenhouse, bicycle frame, motorcycle frame, shelf, fitness equipment, leisure and tourism supplies, steel furniture, various specifications of oil casing, oil pipe and pipeline pipe, water, gas Sewage, air, heating and other fluid transportation, fire fighting and support, construction industry, etc.

Hardness test

Hardness is a pointer to measure the hardness and softness of metal materials. The most commonly used method to determine the hardness of rectangular tubes in production is the indentation hardness method. It uses an indenter with a certain geometry to press into the surface of the tested metal material under a certain load, and tests its hardness value according to the indentation degree.
