Frequently Asked Questions
What is a brushed stainless steel square tube?
It is a square stainless steel tube finished with a controlled directional abrasive grain. The result is a satin appearance suitable for visible architectural and decorative components.
What is the thickness range of this product?
VVINSCO offers wall thicknesses from 0.4mm to 5.0mm. Availability depends on the requested tube size, material grade, quantity and production schedule.
Are SS201, SS304 and SS316 available?
Yes. SS201, SS304/304L and SS316/316L are available subject to specification and order confirmation. Buyers should select the grade according to corrosion exposure, location and budget.
Is a brushed finish the same as a mirror finish?
No. A brushed finish has a visible directional grain and satin appearance. A mirror finish is highly reflective with little visible grain. The required surface sample should be approved before production.
Can the tube be cut, bent, drilled or welded?
Yes. VVINSCO can provide cutting, drilling, punching, notching, bending, welding and laser processing according to the approved drawing. Visible surfaces may require protection or post-fabrication refinishing.
Can the grain direction be controlled?
Yes. The brushing direction and surface sample can be confirmed before production. For adjacent visible components, using the same approved sample and production batch is recommended where practical.
What information is required for a quotation?
- Material grade: SS201, SS304/304L or SS316/316L
- Square outside dimensions and wall thickness
- Required length and total quantity
- Brushed-finish requirement, grain direction and reference sample
- Fabrication drawing and tolerance requirements
- Packing, inspection-document and delivery requirements
- Destination port or delivery location
