1.5 brass square tube

Square tube，Is a title of square pipe，That is, the steel pipe of the side length。It is a steel and processed。Steel tubes in building decoration are essential materials。The square tube is also used in the decoration.，However, we need to understand the size of the square tube first.，Understand the situation of several square tube sizes，Help for your purchase！

What is a square

The square tube knows the literal，It is a tube type of a seed，Many material materials can form a square pipe，It is medium，What use，Where is it?，Most square tubes are mostly steel pipes，Unpacking，smooth，curly，Welding formation round tube，The square tube is then made from the round pipe and then cut into the required length.。Generally50Roots per pack of square tubes in the spot in large-scale10*10*0.8-1.5~~500*500*10-25，Square tube is divided into structured，Decorative square tube，Building，Machinery, etc.。

Square tube is a hollow square cross-sectional light thin-walled steel pipe，Also known as steel refrigeration curved profiles。It isQ235Hot rolled or cold-rolled steel or roll plates for the base material after the cooled bending, the shape of a square cross-sectional steel made of high frequency welding。Hot rolled thick wall tube except for wall thickness，The corners of the corner and the sideline are both levels of exceeding the electrical resistance welding.。

Square tube feature use

Square tube is a hollow square cross-sectional light thin-walled steel pipe，Also known as steel refrigeration curved profiles。It isQ235Hot rolled or cold-rolled steel or roll plates for the base material after the cooled bending, the shape of a square cross-sectional steel made of high frequency welding。Hot rolled thick wall tube except for wall thickness，The corners of the corner and the sideline are both levels of exceeding the electrical resistance welding.。Good comprehensive mechanical performance，Weldability，cold，Hot workability and corrosion resistance，Good low temperature toughness。

2、Square

Square use of the building，Machine made，Steel construction such as steel construction， shipbuilding，Solar power generating bracket，Steel structure engineering，Power Engineering，Power plant，Agriculture and chemical machinery，Glass curtain wall，Car chassis，Airport，Boiler construction，Highway railing，construction，Pressure vessel，Oil storage tank，bridge，Power plant equipment，Lifting transport machinery and other higher load welding structures, etc.。

Square tube identification method

with the development of economy，There are more and more counterfeit products that appear in society.，In order to prevent it from buying a square tube，Don't let yourself be deceived，Then you need to know some knowledge about how to judge the true and false：“We can judge the surface smoothness and level of observation of the surface smoothness of the square tube.，If the surface of the square tube is relatively flat，It can reflect this square tube is good.，Vioence, if the surface is not so flat，And the size and thickness are also irregular，It can reflect this part of the inferior product.。”

Formula calculation formula

Square tube weight calculation formula：4*Wall thickness*（Edge length-Wall thickness）*0.00785

Round tube weight calculation formula：{（perimeter÷3.14）-Wall thickness}*Wall thickness*0.02466

Remark：The above unit iskg/m，Where the wall thickness and side length are millimeters，which ismm。

Editing：The above is the specifications of the new era Xiaobian to provide the specification of the square tube and the specification of the species of the species.，I hope to help friends who have demand in this regard.！For more information on，Please continue to pay attention to our website，Subsequent will present more exciting content。
