Q195 Q235 Q345 Black Steel Square and Rectangular Hollow Tube | ERW, Wall and Length Choices
Black carbon steel hollow tube has actual 0.5–30mm or required wall selection and lengths of 6m, 6.4m or 12m. The body identifies ERW technique and black painted surface with square, rectangular and round shape alternatives.
Outside side dimensions are not provided. Specify the section shape, width, height and feasible wall combination before selecting a length. Q195, Q235 and Q345 are named alternatives; the wider material list does not prove equivalent properties.
For fabrication, state the required GB product specification, finish and cut or bending details. The source application list includes fluid, boiler and structural uses but supplies no pressure rating or load capacity. Request material identification and dimensional inspection evidence rather than inferring suitability from the broad application names.
