Compliant with ASTM A519 (seamless carbon and alloy steel mechanical tubing), this car front fender tube provides structural support for vehicle fenders while protecting critical under-hood components (e.g., radiators, condensers) from debris and low-speed collisions.

Its lightweight carbon steel (1026 grade) construction balances strength and weight—15% lighter than traditional steel tubes—improving vehicle fuel efficiency, while its phosphated coating ensures long-term paint adhesion for a seamless aesthetic match with the fender.
Material Strength: Constructed from 1026 carbon steel (cold-drawn for precision) with tensile strength ≥ 517 MPa and elongation rate ≥ 30% (per ASTM A519). This material resists bending and denting during low-speed collisions (≤5 km/h), with the tube returning to its original shape after minor impacts—reducing repair costs.
Impact Absorption: Absorbs collision energy up to 20 kJ (per ISO 6603-2) by deforming gradually, reducing fender damage in low-speed impacts (e.g., parking lot bumps). The tube’s hollow design acts as a energy absorber, preventing direct force transfer to under-hood components like the radiator.
Weight Advantage: 15% lighter than traditional hot-rolled steel tubes of the same size—e.g., a 1.5m long, 38mm OD tube weighs only 1.2kg (vs. 1.4kg for hot-rolled). This weight reduction lowers the vehicle’s front-end mass, improving handling and reducing fuel consumption by 2–3% (equivalent to 0.5–1 L/100km for compact cars).
Surface Finish: Treated with zinc phosphate coating (per ASTM D7699) to ensure paint adhesion—achieving a paint bond strength of ≥ 5 MPa (per ASTM D4541). The coating also provides temporary rust protection during vehicle assembly, with no need for additional priming before painting.
Passenger Cars: Used in compact and midsize cars (e.g., Honda Civic, Toyota Corolla, Volkswagen Golf) to support front fenders. It reinforces the fender’s shape, preventing sagging over time, and protects the radiator from road debris (e.g., stones, gravel) at highway speeds.
Electric Vehicles: Integrated into EVs (e.g., Tesla Model 3, Nissan Leaf) for weight-saving design—critical for maximizing battery range. The tube’s non-magnetic properties (carbon steel is weakly magnetic) do not interfere with the vehicle’s electronic systems (e.g., GPS, radar sensors).
Performance Cars: Enhances fender rigidity in sports cars (e.g., BMW M3, Porsche 911) to improve aerodynamics. The tube’s precision dimensions ensure the fender maintains its aerodynamic shape at high speeds (200+ km/h), reducing drag and improving stability.
Q: What is the standard length, and can it be cut to fit specific vehicle models?
A: Standard lengths range from 1.2m to 1.8m (in-stock for common models); custom cutting is available to any length (minimum 300mm) with a tolerance of ±2mm. We also offer end-forming services (e.g., flaring, threading) to match OEM fender mounting points—no additional tooling required.
Q: Is it compatible with aftermarket fenders, and does it require modification?
A: Yes, it matches OEM dimensions (OD, wall thickness, mounting hole positions) for most popular car models, making it compatible with both OEM and aftermarket fenders (e.g., fiberglass or carbon fiber fenders). No modification is needed—just bolt it to the vehicle’s chassis using standard OEM hardware.
Q: Does it resist stone chips, and how does it perform in harsh weather?
A: The hardened surface (HRB 65, per ASTM E18) withstands stone impacts at highway speeds (100–120 km/h) without denting or cracking—tested to SAE J400 (gravel impact resistance) with no visible damage after 1000 cycles. In harsh weather (snow, salt), the phosphate coating + paint system resists rust for 5–7 years; we recommend undercoating for vehicles in coastal or cold regions.
