ASTM A554 Welded Tubing

We offer wide range sizes for A5554 welded ornamental tube, including round tube, square tube, rectangular tube and special form dimensions, TIG automatic welding process from stainless steel materials, welding control as standard, bead removed or not removed as request.

We also produce other forms stainless steel tubing for decorative purpose, like bending tubing, elliptic tubing, beside polishing surface performance, brushed finishing , satin finishing and hairline can be performed upon request.

Stainless Steel Material

Stainless steel grades 304/304L, 316L is custom material for ornamental tubing, 201 grade is also used for decorative tubing, Ferritic and Martensitic Stainless Steels are available in bright polishing stainless steel tubing.

Polishing finishing

Stainless steel ornamental tubing is often performed in polishing finishing to make bright surface

  • 180 grit
  • 240 grit
  • 320 grit
  • 400 grit
  • 600 grit – mirror finishing

Quality

Ornamental tubing tolerance is controlled conforming to ASTM A554 mechanical tubing specification, round tubing, square tubing and rectangular tubing can be produced with wide range of dimension, and low roughness value should be inspected outside and inside surface.
