High Tensile Strength. Precision Bending. Engineered for Safety.
Strength Where It Matters Most.
Inside every comfortable car seat lies a complex skeleton of high-strength tubing designed to protect passengers during a collision.
Vertex Tubes supplies structural tubing for Tier 1 automotive suppliers. From complex bent seat frames to precision-notched headrest rods and durable bus handrails, our tubes meet strict automotive safety standards. We offer high Yield Strength materials that allow for thinner walls, helping you achieve vehicle “Lightweighting” goals without compromising safety.
Seat frames require complex 3D bending while maintaining structural integrity.
Material: We supply high-strength carbon steel (e.g., Q195, Q235, STKM 11A) and stainless steel optimized for bending.
Performance: Our tubes withstand tight-radius bending without collapsing or cracking, ensuring the seat frame passes crash tests.
Headrest rods are critical safety components that require thick walls and precise machining.
Solid Feel: We produce heavy-wall small diameter tubes (e.g., 12mm OD x 2.0mm Wall) to replace solid bars, reducing weight.
Processing: We offer inline or offline Notching (Grooving) and Chamfering services for height adjustment mechanisms.
Scratch Resistant: We offer Embossed / Textured Stainless Steel (Linen pattern or Lozenge pattern).
Benefit: The textured surface hides scratches, provides better grip for standing passengers, and reduces fingerprint marks.
| Tensile Strength | Tested per Batch. Meets STKM / ASTM specs. |
|---|---|
| Flattening Test | No Cracks when flattened to 1/2 or 1/3 height. |
| Notch Precision | ± 0.1mm depth/position (For headrest locking). |
| Bending Quality | No Wrinkling on the inner radius of seat frames. |
| Surface Finish | Chrome Plating Ready (For exposed headrest rods). |
A: Yes. This is a major trend for Lightweighting. We produce heavy-wall tubes (e.g., 12mm OD x 2.5mm Wall) that offer similar strength to solid bars but reduce weight by 30-40%.
A: Yes. We have specialized rollers to produce Linen (Cloth) Pattern or Diamond Pattern stainless steel tubes. These are standard for public bus and metro handrails to prevent visible scratching.
A: We commonly use STKM 11A / 13A (Carbon Steel) for strength and formability, or 304 Stainless Steel for exposed luxury seat frames. We can provide mechanical property reports for every heat number.
We understand PPAP and automotive quality requirements.
