- 1. We can do many kinds of surface treatment in our own plant, such as Clear Anodizing, Black Anodizing, Powder Coating, Alkaline Etching, etc.
- 2. If the dimensions you required are not listed in above table, please contact us directly. We’ll do some adjustment according to your requests and try our best to meet your requirements.
What is Drawn Tube ?
An extruded tube brought to final dimension by cold drawing through a die and over a mandrel. This process reduces the cross sectional area of the tube, increases strength and refines the tube surface.Tube Drawing Diagram

Drawn Tube Shapes
Upon special inquiry, we offer drawn shapes including squares,triangles, and flutes. Square and triangular shapes are not supported by the tube straightening process, therefore straightness is not guaranteed.

Fluted TubeDrawn Tube Advantages Vs Extruded Tube
- 1. Dimensional Tolerances-Because the tube is drawn over a mandrel and through a die, consistent dimensions can be achieved.
- 2. Superior Strength-Coldwork increases tube strength and is stronger that an equivalent extruded tube.
- 3. Attractive Appearance-The drawing process enhances tube cosmetics by producing a bright finish with no weld lines.
- 4. Machining-The drawn tube’s superior strength and hardness characteristicsenhance tube machinability. This assures a better machined surface with less gumming.
- 5. Bending-Better dimensional and temper characteristics greatly enhance tube bending operations. Consistent dimensions and temper reduce bender setuptime and require less machine adjustments. Tube spring back is enhanced. Precise bendscan be obtained.
- 6. Anodizing-The draw process refines the surface of the tube eliminating extrusion die lines and other surface irregularities. This provides a superior finish for bright dip and etch and clear anodizing.
Porthole VS Seamless -Market Look
- 1. Porthole drawn tube is suitable for many tube applications -flagpoles, antennas, conveyor rolls, textile spools, orthopedic applications, recreational, marine applications.
- 2. Seamless tube is better suited for high stress applications such as hydraulic cylinder tube used in trench shoring devices, photocopiers, bicycle, kicking scooters, etc.
