Round DOM Roll Cage Tubing Structural Steel Pipe DOM Tubing For Roll Cage

【Material】

Drawn Over Mandrel (DOM) tubing is produced by electric resistance welding of carbon-steel strip followed by cold drawing over a mandrel to remove weld flash and enhance mechanical properties. This process yields:

  • Uniform wall thickness and concentric OD/ID.

  • Improved yield and tensile strength compared to standard ERW tubes.

  • Smooth OD/ID surfaces, requiring minimal machining.

【Specifications】

Property Value
OD range 3/16″ to 5″ (4.76 mm to 127 mm)
Wall thickness 0.028″ to 0.625″ (0.71 mm to 15.88 mm)
Length Random lengths 17′–24′ (5.18 m–7.32 m); cut-to-length available
Tolerances ±0.005″ for OD; ±0.003″ for wall thickness
Surface finish Pickled and oiled; optional honing for hydraulic applications

【Chemical Composition】

Grade C Mn P (max) S (max)
SAE 1020 0.18–0.23 0.30–0.60 0.04 0.05
SAE 1026 0.22–0.28 0.60–0.90 0.015 0.005
SAE 520 0.17–0.23 0.30–0.60 0.04 0.05
EN-ST52.3 ≤ 0.22 ≤ 1.60 ≤ 0.025 ≤ 0.025
AISI 4130 0.28–0.33 0.40–0.60 0.035 0.040

【Mechanical Performance】

Grade Yield Strength (MPa) Tensile Strength (MPa) Elongation (%)
SAE 1020 512 602 15
SAE 1026 517 586–690 15
SAE 520 512 602 15
EN-ST52.3 ≥ 355 510–690 ≥ 20
AISI 4130 ≥ 482 ≥ 586 ≥ 20

【Main Features】

  • High Strength-to-Weight Ratio: Superior yield and tensile properties for lightweight yet robust roll-cage structures.

  • Precision Dimensions: Tight tolerances reduce machining time and ensure consistent fitment.

  • Excellent Weldability: Low sulfur and phosphorus content facilitates gas- and arc-welding without pre- or post-heat in most grades.

  • Uniform Grain Structure: Cold drawing promotes refined microstructure and improved fatigue resistance.

【Standards & Specifications】

Region Standard Scope
USA ASTM A513 Type 5 Cold-drawn ERW carbon-steel mechanical tubing
USA ASTM A500 Cold-formed welded or seamless structural tubing
EU EN 10305-3 Welded, cold-sized precision steel tubes
Russia GOST 8732 Electric-welded steel tubes
Japan JIS G3445 Welded steel precision tubes
China GB/T 3094 Welded, cold-drawn precision steel tubes

【Application Fields】

Automotive & Motorsports

  • Roll Cages: Main chassis members, hoop assemblies, cross-bracing

  • Chassis Tubing: Frame rails, suspension links

  • Drive Shafts & Axle Tubes

Industrial & Construction

  • Hydraulic Cylinders: Honing stock for rods and barrels

  • Pneumatic Systems: Cylinder bodies

  • Structural Supports: Frames and guard rails

Usage Examples

  • Roll Cage A-Pillar Hoop: 1.75″ × 0.120″ DOM 1026 for FIA compliance

  • Main Hoop Backbone: 2.00″ × 0.120″ AISI 4130 for maximum strength

  • Honing Stock: EN-ST52.3 for hydraulic rams requiring honed ID
