Q1: What are the main steel grades used for spinning bike frame tubes and why?

A: STKM11, STKM12, E235, E355, Q195, Q235B, and Q355B are primary choices. These grades offer a balance of tensile strength (320-570 MPa), easy formability, reliable weldability, and cost-effectiveness suitable for fitness equipment subject to dynamic loads.

Q2: How does wall thickness affect the frame's performance?

A: Thicker walls (2.5-3.0 mm) increase rigidity and weight tolerance, ideal for commercial-grade bikes; thinner walls (

Q3: What surface finishes are available for the tubes?

A: Black, oiled, phosphated, or powder coated finishes are standard. Finishing enhances corrosion protection, aesthetics, and paint adhesion; the choice depends on usage scenario (indoor gym vs. outdoor park).

Q4: What forming technologies are used for Shaped Steel Tube for Spinning Bike Frame?

A: Cold forming and electric resistance welded (ERW) processes are preferred. These deliver precise dimension control, consistent wall thickness, and customizable profiles.

Q5: What standards must spinning bike frame tubes comply with?

A: EN10305-3 (Europe), JIS G 3445 (Japan), and GB/T 13793 (China) are most relevant. These standards cover chemical composition, mechanical properties, dimensional tolerances, and non-destructive testing.

Q6: Can special cross-sections (oval, D, triangle) be customized?

A: Yes. HEBEI CBIES offers custom tooling to deliver round, oval, flat, triangular, and even designer cross-sections to suit distinct brand geometries and ergonomic requirements.

Q7: What documentation comes with each batch?

A: Each shipment includes steel mill certificates, mechanical property test reports, dimension sheets, and optionally, surface finish reports.
