Galvanized square tube in a welded light-fabrication direction for greenhouse frames, fencing, gates and small supports. Review 20×20–60×60 mm sections, 1.0–2.5 mm wall options and a 6 m reference length. Confirm grade, coating, tolerance and packing per order.
This welded galvanized square tube is intended for light fabrication such as greenhouse frames, fencing, gates and small support assemblies. A working specification of 20×20–60×60 mm outside size, 1.0–2.5 mm wall thickness and 6 m reference length can be reviewed, but the final section, grade, coating and tolerance remain confirm per order.
The square section gives fabricators a flat-sided profile for brackets, fence panels, frame joints and light support work. The welded construction is suitable for applications that do not require seamless tube. Confirm the project load, connection method and corrosion exposure before selecting the section. The flat faces also simplify bracket placement and general workshop cutting. The section is easy to identify in a mixed fabrication order.
Q195 and Q235B are suggested grade directions for this light-fabrication concept, not a single confirmed supply grade. The buyer should state the required grade, standard, zinc coating, corner condition and surface appearance in the quotation. Keep the selected grade and dimensions consistent across the drawing and purchase order. Confirm the visible face before production.

This light square-tube direction can be reviewed for greenhouse and general fabrication projects where a compact flat-sided section is useful. The square tube suits small frames and accessories that need consistent sides for joining. Greenhouse and fence fabricators can review the section against their own drawings. It is not a heavy structural engineering section; confirm project load, connection method and exposure before selection.
Confirm cutting, drilling, welding, punching and end preparation with the fabricator’s drawing. Keep the galvanized surface protected at cut and weld areas according to the project’s finishing method. Confirm corner radius and dimensional tolerance before production. State whether the frame will be painted, welded or mechanically joined after delivery. Record the approved section and cutting tolerance on the order.
Confirm bundle length, quantity per bundle, strapping, moisture protection, marking and loading requirements per order. Use separators or protective wrapping where the finished surface may rub during transport. Keep mixed sizes identified during loading. Protect open ends and visible faces during handling.
No. This square tube is welded galvanized steel for light fabrication and frame work.
No heavy-engineering claim is made. Confirm the project load and design before use.
The working direction is 20×20–60×60 mm. Confirm the exact side length and tolerance per order.
Q195 or Q235B may be reviewed, but the quotation must name one confirmed grade and standard.
Cutting can be reviewed when the required length and tolerance are stated.
Send side size, thickness, grade, coating, length, quantity, finish, tolerance and packing requirements.
