Black square tube for greenhouse frames, fences, racks and light fabrication. Confirm side size, wall thickness, grade, length, processing details and MOQ per order.
Source black square tube for frames, fences, greenhouse structures and light fabrication. The square section gives fabricators four flat faces for layout and joining, while the final size, wall thickness, grade and production route are confirmed against the project requirement.
Black square tube suits projects that need a clean rectangular section for cutting, welding and frame assembly. Q195, Q235B, A36 or another approved grade may be reviewed, but the selected grade must match the buyer’s drawing and governing standard. Flat faces simplify layout and make many frame connections easier to mark. The section also gives a consistent reference for simple workshop jigs.
Black square tube is positioned for light fabrication rather than an unqualified heavy structural claim. Section size, wall thickness, corner condition, length and inspection documents should be agreed before quotation so the buyer receives a specification that can be checked. The written order should identify the intended frame or fabrication use. This detail helps separate light fabrication requirements from structural specifications.

Square tube helps buyers build light frames with consistent flat faces and straightforward corner connections. The selected section must still be checked against the project’s span, connection method and service conditions; this page does not assign an engineering load rating. Send the drawing when the frame has defined joints or spans.
The final use should be confirmed before quotation.
Confirm cutting, drilling, notching, welding and end treatment before production. A drawing or cutting list helps align the side size, wall thickness and finished length with the assembly. Mark hole locations and finished lengths clearly when the tube will be assembled into a frame. Confirm the corner requirement before cutting. State whether the frame needs plain or prepared ends before cutting.
Square tubes are bundled for handling and shipment. Bundle marking, protection, loading method and destination details are confirmed with the order quantity and dimensions. The final packing arrangement follows the ordered side size and length. Bundle marks can carry the buyer’s order reference.
Side size is confirmed per order. Send the required outside dimensions and wall thickness for an accurate review.
The page is positioned for light fabrication. Any structural use requires an engineer’s specification and confirmation of the selected section.
Q195, Q235B and A36 are review directions. The final grade follows the approved standard and project requirement.
Yes. Provide a cutting list or drawing so finished lengths and allowable tolerances can be confirmed.
Drilling and notching can be reviewed before production when the buyer supplies dimensions and locations.
MOQ is confirmed per order based on size, wall thickness, grade, length, packing and production arrangement.
