Precision chassis & structural parts for global OEMs
We manufacture high-strength automotive chassis assemblies, floor pans, firewall sections, inner fenderwells, and frame reinforcements engineered to tight OEM dimensional tolerances and rigorous crashworthiness requirements.
Chassis & Structural Product Range
Engineered body-in-white sub-assemblies and load-bearing chassis parts produced with high-tonnage stamping, automated robotic welding, and tight geometric tolerances.
Deep-draw stamped floor sections and ribbed pan assemblies engineered for torsional rigidity and NVH dampening.
Precision formed engine-bay bulkheads with integrated pass-throughs, reinforcement embossments, and heat-shield mounts.
Multi-piece and single-draw wheel housing panels designed to absorb shock loads and resist corrosion from road debris.
Heavy-gauge gussets, subframe ties, and chassis crossmembers engineered for maximum load transfer and impact safety.
Automotive Grade Production Standards
CMM dimensional verification, robotic seam inspection, and full lot traceability for Tier 1 and aftermarket programs.
How your parts move from sheet to finished product
Every step follows strict dimensional tolerances from raw coil to final protective coating. Our controlled factory floor supports predictable turnaround and repeatability.
Custom production scheduling
Have unique gauge requirements, rapid prototype turnarounds, or specific QA check plans? Our engineering team reviews step-by-step manufacturability within 24 hours.
Traceable material certs (MTR), first-article inspections (FAI), and full batch records provided with every run.
Materials and structural tolerances for automotive sheet metal
Choose from certified carbon steels, HSLA alloys, and structural aluminum grades engineered for high-impact assemblies and tight tolerances.
Exposed brackets, interior structural brackets, chassis clips, and high-finish body mountings.
Heavy-duty suspension brackets, crossmembers, towing fixtures, and undercarriage frames.
Wheel well housings, floor pans, battery tray reinforcement, and sub-frame panels.
B-pillar reinforcements, impact crossbeams, bumper reinforcement beams, and crash structures.
EV battery enclosure shells, hydraulic tank brackets, splash shields, and lightweight heat shields.
Motor mounts, chassis stiffener plates, structural battery rack profiles, and machined-stamped nodes.
