Product Description

High-Precision Slotting Stainless Steel Tube with Custom Cutting Patterns

Product Description
Our 304 & 316L Stainless Steel Tube Service offers custom fabrication of tubing, transforming standard shapes into sophisticated components. We perform precise cutting, create clean slots or perforations via laser or machining, and apply decorative or functional knurling. These processes enhance 304 or 316L stainless steel's durability, making it ideal for applications needing precise dimensions, fluid handling, enhanced grip, or aesthetic appeal.

Product Processing
Our process handles multiple operations in a controlled workflow.

Material Verification & Preparation: Certified 304 or 316L tubing is verified, straightened, and cleaned.
Precision Cutting: Tubes are cut to exact lengths with saws or lasers, ensuring square, burr-free ends.
Slotting/Perforation:

Laser Slotting: CNC laser cuts complex 2D patterns, slots, or holes around the tube.
CNC Milling Slotting: CNC machines create precise, straight, or angled slots with specific edge quality.
Knurling: Tubes are mounted in a machine. Knurling wheels create textured patterns over full or sectional lengths.
Deburring & Finishing: Cut edges are deburred, and tubes may be tumbled, brushed, or electropolished to enhance corrosion resistance.
Final Inspection & Cleaning: Tubes are inspected for dimensions, knurling consistency, and surface quality, followed by a final cleaning.
