If there is any deviation, please include more3. Basic productuare tube is a hollow steel with a certain cross-section shape and size, and is one of the four major varieties of steel (plate, tube, type, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (special-shaped steel). Simple section steel refers to square steel, round steel, flat steel, Angle steel, hexagonal steel, etc. Complex section steel refers to I-beam steel, channel steel, rail, window frame steel, curved section steel, etc. Square pipe is generally used in machining, structural connection, container, etc.5. Classification of production standards and implementationuare pipe according to production standards: national standard square pipe, Japanese standard square pipe, British square pipe, American standard square pipe, European standard square pipe, non-standard square pipe.European standard square pipe executive standard: EN10210 standard, material: S235/S275/S355(JR/J0/J2)American standard square pipe implementation standard: ASTM standard, material: A36/A572GR50/A992, A500/A588Japanese corner square pipe implementation standard: JIS standard, material: SS4006.
