How Should Wall Thickness Be Selected?
| Thickness Range |
General Purchasing Consideration |
| 0.6 -0.9mm |
Lower weight and easier handling for light decorative parts, covers, displays and non-load-critical frames. |
| 1.0 -1.5mm |
Commonly considered for furniture, partitions, frames and general fabrication requiring greater rigidity. |
| 2.0mm |
Provides more material section and rigidity for demanding fabrication, subject to joint design and engineering requirements. |
Engineering note: Wall thickness alone does not determine safe load capacity. Span, support, weld design, grade, fabrication quality and service conditions must also be evaluated by the project engineer.
Which Stainless Steel Grade Should You Choose?
| Grade |
Recommended Environment |
Purchasing Guidance |
| 201 |
Dry indoor decorative projects |
A cost-conscious choice for furniture, displays and interior decoration where moisture and chloride exposure are limited. |
| 304 |
General interior and architectural applications |
A widely used grade for furniture, frames, commercial interiors and general fabrication. |
| 316 |
Coastal, humid or chloride-exposed environments |
Offers improved resistance to chloride-related corrosion. Final selection should be based on the actual service conditions. |
Satin or Mirror Finish?
Satin / Brushed
A directional, low-glare finish commonly selected for furniture, partitions, door frames and frequently handled components. Confirm the polishing grit or approved sample.
Mirror Polished
A highly reflective decorative finish for premium interiors and feature fabrication. Protective film and careful handling are recommended.
Typical Applications
- Stainless steel furniture and table frames
- Decorative partitions, screens and display structures
- Door frames, window frames and cabinet structures
- Retail fixtures, shelving and exhibition fabrication
- Railings, decorative grids and architectural metalwork
- Custom components requiring cutting, drilling or welding
Can the Tube Be Cut, Bent, Drilled or Welded?
Yes. VVINSCO can supply straight lengths or evaluate cutting, bending, drilling, laser cutting, welding, polishing and end preparation. Processing feasibility depends on grade, wall thickness, bend radius, hole pattern, finish and dimensional tolerance. Send a drawing or sample for confirmation before mass production.

Buyer FAQs
What is the exact section size?
The tube has a 20mm × 20mm external square section. Wall thickness is selected separately from 0.6mm to 2.0mm.
Does a thicker wall always mean better corrosion resistance?
No. Thickness influences rigidity and available material section, while corrosion performance depends mainly on grade, surface condition, fabrication, environment and maintenance.
Are satin and mirror the same surface?
No. Satin is directional and low-glare; mirror is highly reflective. Specify one finish or approve a physical sample.
Can VVINSCO produce custom lengths and holes?
Yes. Cut lengths, hole patterns and other fabrication can be evaluated from the drawing, tolerances, grade, thickness and quantity.
Which grade is recommended for coastal locations?
Grade 316 should be considered for coastal, humid or chloride-exposed environments. Final selection should reflect the actual project conditions.
What information is required for a quotation?
Provide grade, 20×20mm size, wall thickness, finish, length, quantity, processing drawing, packing requirement and destination port.
