At present, the Ministry of Construction has built some steel structure test buildings in industrial and civil buildings, such as
Two steel structure demonstration residences of the Ministry of Construction were built in Tianjin in 2002. Steel pipes were used in this project
Concrete column steel beam frame steel reinforced concrete core tube (SRC) structural system, total project area
8000m2, the main body has eleven floors, one column is made of round pipe, and the other column is made of square steel pipe
350x350mm, the thickness varies with the floor, of which the 1~3 floors are 16mm, 4~
14mm for the 6th floor, 12mm for the 7th to 9th floor, 10mm for the 10th to 11th floor, and poured in the steel pipe
C40 concrete. The beam is made of welded I-beam with the specification of 350x200x10x18mm, and the floor slab
It is a prestressed composite slab with high-strength spiral rib reinforcement. At that time, no manufacturer in China produced square tubes with such a large diameter, so square steel tubes were used in the project, which were four plate welded BOX columns. Square tube factory

01 straight cutting of the members at the joints and good bending performance
As a structural member, the rectangular steel tube not only inherits almost all the advantages of the round steel tube, but also has the advantages of straight cutting of the members at the joints and good bending performance, which is widely used in developed countries. The rectangular steel pipe with direct welding joints does not need stiffening plates and gusset plates, which reduces the amount of steel used for joints, makes the joint form simple and clear, and facilitates the connection of components .It is also more beautiful.

- 02 Performance index analysis of square tube - high hardness
Hardness is a pointer to measure the hardness of metal materials. At present, the most commonly used hardness measurement method in production is the indentation hardness method, which uses an indenter with a certain geometric shape to press into the surface of the metal material to be tested under a certain load, and determines its hardness value according to the degree of indentation.
Common methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).
3 CERTIFICATION IS
COMPLETE
can produce steel pipe products of world
stardard,such as European standard,American standard,
Japanese standard,Astralian standard,natinal standard
and so on.
04 Performance index analysis of square tube - good impact toughness
The load acting on the machine at a high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.
THE ONLY
rectangular tube manufacturer selected into the top ten steel tube brands in China
