1. Product Range & Specifications

We supply stainless steel welded round, square, rectangular, oval, slotted and decorative tubes. Production availability depends on grade, shape, thickness and order quantity.

Sizes shown are overall product-family ranges, not a guarantee that every size, grade and thickness combination is available. Final specifications and tolerances are subject to order confirmation.

2. Popular Sizes for Your Market

Common railing tube thicknesses: 1.2, 1.5 and 2.0 mm, subject to size and availability. Custom lengths and finishes can be discussed for project orders.

3. International Standards & Buyer Specifications

We welcome inquiries referencing standards used in different markets. ASTM A554 is a principal specification for applicable welded stainless steel mechanical tubing, including round and shaped sections. Other standards below describe distinct product applications and must be evaluated separately.

Compliance notice: The standards above are search and inquiry references, not interchangeable specifications or claims of certification. Applicable standard, edition, testing, material certificates and actual compliance must be confirmed in the purchase agreement. Pressure, hygienic and fluid-service products require separate suitability review.

4. Surface Finishes & Customized Appearance

Choose a finish that suits your customer's project: brushed or satin for railing systems, bright brushed 600G for decorative furniture, mirror 6K/8K for reflective designs, and selected PVD colors for architectural features. Finish appearance and color consistency should be approved against samples for critical projects.
