Galvanized square rectangle steel tube It’s a name for square pipe and rectangular pipe, which is the pipe with the same side length. It is made of strip steel after processing and rolling. Generally, the strip is unpacked, leveled, crimped and welded into a round tube, which is rolled into a square tube and then cut into the required length. Usually 50 sticks per pack. Also known as square and rectangular cold formed hollow steel, referred to as square pipe and rectangular pipe, code F and J respectively.

Galvanized Square Rectangle Steel Tube The Paper

1.Galvanized square rectangle steel tube, The allowable deviation of wall thickness shall not exceed positive or negative 10% of the nominal wall thickness when the wall thickness is less than 10mm, and positive or negative 8% of the nominal wall thickness when the wall thickness is greater than 10mm, except for the wall thickness of the corner and weld zone.

2.Galvanized square rectangle steel tube, The usual delivery length is 4000mm-12000mm, with 6000mm and 12000mm in the majority. Square rectangular tube allows delivery of not less than 2000mm short and irregular products, can also be delivered in the form of interface tube, but the customer should remove the interface tube when using. The weight of short and irregular length products shall not exceed 5% of the total delivery quantity, and for square rectangular tubes with theoretical weight greater than 20kg/m shall not exceed 10% of the total delivery quantity.

3.Galvanized square rectangle steel tube, The bending degree shall not be greater than 2mm per meter, and the total bending degree shall not be greater than 0.2% of the total length.
