Rectangular Steel Pipe

Introduction:
Taking hot rolling steel and cold rolled steel strip as raw material, passing the bending process and the high-frequency welding, we manufacture the square cross sections steel. It is also known as the square steel pipe. The hot rolling square steel pipe has a much thicker wall, in addition, the size of its corner and the straightness of its edge are all reach of even surpass the standard of cold electric resistance welding.

Application fields: construction, mechanical manufacture, steel construction project, shipbuilding, solar power stents, steel structure work, power engineering, electricity generating station, agricultural and chemical machinery, glass block screen wall, automotive chassis, airport, boiler construction, highway railing, housing construction, etc.

Main Component:
The raw material is strip steel.

Note:
1.It is applied in accordance with the customer's specific circumstances.
2.For fear of rusting in the long time ocean shipping, the steel pipes are all sprayed anticorrosive paint before exporting.

Square and rectangular Steel Pipe

Introduction:
It is also called square cold rolled hollow section. The code is F and J.
1. The square and rectangle steel pipe have tolerance. When the wall thickness is no more than 10mm, the tolerance is within +/-10% of the nominal wall thickness. When the thickness is more than 10mm, the tolerance will be within 8% of the nominal wall thickness, the bending point and the welding seam will be excluded.
2. The usual length of square pipe is about 4000mm-12000mm. 6000mm and 12000mm are the common length. The square pipe allows the shortage length and random length less than 2000mm. And it also allows the joint pipe. But then buyer has to cut the joint during construction.
The weight for the shortage length and random length can not be more than 5% of the total weight. It can not be more than 10% of total weight for the theoretical weight more than 20kgs/m.
3. The bending can not be more than 2mm/m, and the total bending can not be more than 0.2% of total length.
