19mm (3/4 Inch) 316 Stainless Steel Round Tube 0.4-3.0mm Wall Thickness Welded Pipe

1. Product Specifications

Dimension note: 3/4 inch equals 19.05 mm. This product is specified as 19.00 mm OD; confirm the required diameter and tolerance on your drawing or purchase order. The wall thickness range is a capability indication, not a guarantee that every thickness is stocked.

2. Why Choose Grade 316?

Grade 316 is a molybdenum-bearing austenitic stainless steel with improved resistance to certain corrosive environments compared with Grade 304. It is often selected for architectural fittings, furniture and fabrication projects where corrosion resistance and surface appearance matter. Suitability depends on exposure conditions, fabrication and maintenance; marine or chloride-rich environments require project-specific evaluation.

3. Available Surface Finishes

• 2B: Smooth cold-rolled appearance where applicable.
• BA: Bright annealed appearance, subject to production availability.
• Brushed / Satin: Directional decorative finish for architectural and furniture use.
• 6K / 8K Mirror: High-reflectivity polished appearance for selected orders.

Surface appearance and polishing level can be confirmed with reference samples before mass production.

4. Typical Applications

• Decorative handrail and railing components
• Furniture frames, chair and table components
• Interior architectural decoration
• Custom metal fabrication and display systems
• Stainless steel assemblies requiring a 19mm round profile

For load-bearing railings, pressure service, sanitary service or other regulated uses, the purchaser must specify applicable design, product and testing requirements. This decorative welded tube listing does not by itself establish suitability for those services.

5. Factory Production & Quality Control

VVINSCO manages production through material selection, strip preparation, tube forming, welding, sizing, straightening, surface finishing, cutting and packing. Inspection can cover:

• Material grade and raw material documentation
• Outside diameter, wall thickness and length
• Weld seam appearance and tube straightness
• Surface finish, scratches and visual quality
• Quantity, labeling and export packaging

Material test certificates and additional testing may be arranged when specified and agreed before order confirmation.

6. OEM & Custom Tube Processing

As a manufacturer, we welcome custom requests for 19mm Grade 316 round tubes. Send your drawings or sample requirements for cut lengths, polishing, drilling, bending and other fabrication services. Feasibility, minimum order quantity, tolerances and lead time are confirmed during quotation.

7. Export Packaging

Depending on finish and shipment method, we offer protective film, woven-bag bundles, labels and wooden cases. Packaging arrangements are agreed with the buyer to help protect tube surfaces during international transport.
