AISI ASTM Stainless Steel Seamless Square Rectangular Tube Pipe
201/304/310/316/316 l / 321/904/2205/2507 Product Description
Square rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel by processing and rolling. Generally, the strip is unpacked, flat, crimped, welded to form a round tube, which is then rolled into a square tube and cut to the required length.
Also known as square and rectangular cold-formed hollow steel, referred to as square tube and rectangular tube, code F and J respectively
1. The allowable deviation of the wall thickness of the square rectangular pipe shall not exceed plus or minus 10% of the nominal wall thickness when the wall thickness is less than 10mm, and plus or minus 8% of the wall thickness when the wall thickness is greater than 10mm, except for the wall thickness of the corner and weld area.
Square square pipe
2. The usual delivery length of rectangular tubes is 4000mm-12000mm, with 6000mm and 12000mm being the majority. Square pipe allows the delivery of not less than 2000mm short size and non-fixed size products, can also be delivered in the form of interface pipe, but the buyer should cut the interface pipe when in use. The weight of short size and non-fixed size products shall not exceed 5% of the total delivery volume, and for square pipe with a theoretical weight greater than 20kg/m, it shall not exceed 10% of the total delivery volume
3, the bending of the square tube shall not be greater than 2mm per meter, and the total bending shall not be greater than 0.2% of the total length

| No.2B |
The surface brightness and flatness of No.2B is better than No.2D. then through a special surface treatment to improve its mechanical properties,No.2B could nearly satisfy comprehensive uses. |
| No.3 |
Polished with abrasive belt of git#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
| No.4 |
Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
| HL |
Polished with abrasive belt of grit #150-#320 on the No.4 finish and has continuous streaks, mainly used as buildings ornaments elevators,
door of building, frontal plate etc. |
| BA |
Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus,ornament etc. |
| 8K |
The product have excellent brightness and prefer reflexivity can to be the mirror. |
The thin steel plate is immersed in the dissolved zinc bath so that its surface adheres to a thin steel plate. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the plating groove dissolved with zinc to make galvanized steel plate. This steel plate is also made by hot immersion, but after the groove, it is immediately heated to about 500 ºC, so that it generates an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weld ability.
Galvanized coil can be divided into hot rolled galvanized coil and cold rolled galvanized coil, they are mainly used in the construction of household appliances, car containers, transportation and other fields, especially steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries their characteristics are mainly: strong corrosion resistance, good surface quality, economic and practical.
