Product Q&A

Q:Where is this product usually used?

It is used for welded frames, rack frames, equipment frames, fence frames, support structures and simple processed tube components.

Q:Is this a galvanized square tube?

No. This entry is for black / mill-finish / ungalvanized carbon steel square tube.

Q:Can rectangular tube be supplied too?

Rectangular tube can be discussed as a related option when the frame needs a different section proportion, but this entry stays focused on square tube.

Q:Can holes or simple processing be added?

Yes. Drilling or punching can be arranged when the part needs holes for bolts, clips, brackets, mesh fixing or assembly points.

Q:Can the tube be painted or galvanized later?

Painting or hot-dip galvanizing after fabrication can be arranged as an order-specific processing route when needed.
