Wall Thickness Selection Guide
| Thickness Range | General Purchasing Consideration |
|---|---|
| 0.5 - 0.9mm | Light decorative components, trim frames, displays and furniture details where lower weight is preferred. |
| 1.0 - 1.5mm | Commonly considered for furniture frames, partitions, decorative railing components and general fabrication. |
| 2.0 - 2.7mm | Provides greater material section and rigidity for more demanding fabricated frames and railing components, subject to engineering verification. |
Engineering note: Wall thickness alone does not determine safe load capacity. Span, support, joint design, weld quality, grade and service conditions must also be evaluated for load-bearing applications.
Stainless Steel Grade Selection
| Grade | Recommended Environment | Purchasing Guidance |
|---|---|---|
| 201 | Dry indoor decorative projects | A cost-conscious option for furniture, displays and indoor decoration where moisture and chloride exposure are limited. |
| 304 | General interior and architectural applications | A widely selected grade for railings, furniture, frames and general-purpose fabrication. |
| 316 | Coastal, humid or chloride-exposed environments | Offers improved resistance to chloride-related corrosion. Final selection should reflect the actual service environment. |
Surface Finish Options
Satin / Brushed
A directional, low-glare finish frequently selected for railings, furniture, door frames and commercial interiors. 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.
Dimensional Specifications
The exact outside dimensions are 20mm × 40mm, approximately 0.787 inch × 1.575 inch. These values are sometimes described commercially as about 3/4 × 1-1/2 inches, but they are not exact substitutes. Use the metric dimensions when matching fittings, holes or fabricated components.
Typical Applications
- Stainless steel railings, balustrades and infill frames
- Furniture frames, table structures and shelving
- Door frames, window frames and cabinet structures
- Decorative partitions, screens and architectural grids
- Retail displays, exhibition stands and commercial interiors
- Custom components requiring cutting, drilling or welding
Custom Fabrication Services
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 before mass production.
Quality Assurance
- Material grade verification against the confirmed order
- 20×40mm section size and wall-thickness measurement
- Length, straightness, corner profile and tube-end inspection
- Weld-seam and surface-finish inspection under suitable lighting
- Quantity, label, protective film and packing verification
- Material documents or agreed inspection records can be discussed before ordering
Packaging and Protection
Packing is selected according to the finish, bundle weight and shipment method. Options can include protective film or individual plastic sleeves, bundled tubes, woven outer wrapping, reinforced supports or wooden cases for suitable shipments. Mirror-polished tubes require additional protection against contact scratches.

Frequently Asked Questions
What is the exact tube size?
The outside section is 20mm × 40mm. Wall thickness is selected separately from 0.5mm to 2.7mm.
Is this tube suitable for outdoor railings?
Grade 304 may suit many general applications, while 316 should be considered for coastal or chloride-exposed locations. Grade 201 is mainly recommended for dry indoor decoration. Final selection depends on the actual environment.
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 provide holes and custom cut lengths?
Yes. Cut lengths, hole patterns and other fabrication can be evaluated from the drawing, tolerances, grade, thickness and quantity.
Does thicker tube automatically guarantee a safe railing?
No. Safe railing performance also depends on span, posts, joints, anchors, welds, design loads and local building requirements.
What information is required for a quotation?
Provide grade, 20×40mm size, wall thickness, finish, length, quantity, processing drawing, packing requirement and destination port.
