Source black rectangular tube for railings, frames, door and window supports and other light fabrication. The rectangular section gives the buyer two principal face dimensions for layout, while size, wall thickness, grade, length and production route are confirmed per order.
Black rectangular tube offers a practical section for assemblies that need a defined wide face and narrow face. Q195, Q235B, A36 or another approved grade may be reviewed, but the final material must follow the project drawing and named supply standard. The flat faces give fabricators a clear reference for brackets and finishing work. The section also helps keep the visible orientation consistent during assembly.
Black rectangular tube is planned for light fabrication, not an automatic heavy-engineering claim. Buyers should confirm the section dimensions, wall thickness, corner condition and end treatment before quotation, especially when the tube will be joined to plates, brackets or other profiles. A drawing keeps the wide-face orientation clear during quotation. The same detail helps the buyer review joints, brackets and finishing positions.

Rectangular tube helps fabricators create light assemblies with a clear wide face for fixing, lining or finishing. The chosen section must be checked against the project’s span, connection details and service conditions; no load rating is assigned without an engineering specification. Provide the drawing when orientation or joint detail matters.
The final use should be confirmed before quotation.
Confirm cutting, drilling, notching, welding, beveling and end treatment before production. A drawing helps match the two outside dimensions and finished length to the assembly. Mark the wide face, hole positions and cut lengths when the tube will connect to brackets or plates. Confirm the corner requirement before cutting. State whether the frame needs plain or prepared ends before cutting.
Rectangular tubes are bundled for handling and shipment. Bundle marks, surface protection, loading method and destination requirements are confirmed with the order quantity and dimensions. The final packing arrangement follows the ordered section and length. Bundle marks can carry the buyer’s order reference.
Outside dimensions are confirmed per order. Provide the wide face, narrow face and wall thickness for review.
Black rectangular tube is positioned for light fabrication. Structural use requires an engineer’s specification and confirmation of the selected section.
Q195, Q235B and A36 are possible review directions. The final grade follows the approved standard.
Yes. Send the cutting list or drawing so finished length and processing details can be confirmed.
Cutting, drilling, notching, beveling or another end condition can be reviewed before production.
MOQ depends on dimensions, wall thickness, grade, length, packing and production arrangement, so it is confirmed per order.
