# Commercial Frame Straightening, Heavy Collision Repair & PPG Fleet Refinishing

> Restore factory frame-rail geometry, repair aluminum and fiberglass cabs, and refinish multi-unit commercial fleets in our 60-foot heated downdraft paint booths.

## Before & After Case Study: Class 6–7 Commercial Chassis Frame Alignment, Cab Reconstruction & Fleet Color Match
- **Turnaround Time:** 2.5 Weeks
- **Direct Commercial Insurance Billing:** Available
- **BEFORE: Jackknife Frame Twist & Front-Quarter Collision Damage:** Diamond-twisted C-channel frame rails, displaced front steer axle hanger brackets, crushed composite tilt hood, and damaged radiator/charge-air-cooler assembly following a winter highway incident.
- **AFTER: Laser-True Frame Geometry & Factory PPG Metallic Finish:** Multi-tower hydraulic frame rack correction within OEM millimeter tolerances, new Hendrickson suspension hangers, OEM hood/bumper replacement, computerized 3-axle alignment, and seamless PPG Delfleet clearcoat finish.

## Project ROI & Highlights
- **Frame Accuracy:** ±1.5 mm Laser (Computerized centerline & tandem thrust verification)
- **Spray Booth Capacity:** 60-Ft Downdraft (Baked cure cycles for tractors, wreckers & box trucks)
- **Insurance Claims:** Direct Billing (Works with all commercial trucking insurers)
- **Tire Wear Reduction:** +30% Tread Life (After 3-axle laser frame & tandem alignment)

## 5-Stage Restoration & Repair Workflow
- **Phase 1 — Digital Insurance Estimate & Laser Audit:** Laser frame centerline mapping for sway, sag, twist, and diamond distortion, paired with direct commercial adjuster documentation.
- **Phase 2 — Hydraulic Multi-Tower Frame Correction:** Cold-pull hydraulic rack straightening of 50,000–120,000 PSI commercial C-channel rails without weakening heat-treated steel.
- **Phase 3 — Cab, Hood & Box Structural Repair:** SMC fiberglass hood rebuilding, riveted aluminum cab panel replacement, and dry-freight/dump body structural welding.
- **Phase 4 — 60-Foot Downdraft PPG Refinish:** Corrosion-inhibiting epoxy primer, spectrophotometer fleet color matching, and baked urethane clearcoat application.
- **Phase 5 — 3-Axle Alignment & DOT Release:** Total vehicle thrust-angle alignment, ADAS/radar sensor calibration, cooling system pressure test, and DOT road-test release.

## Body Shop Capabilities
- **Heavy-Duty Multi-Tower Frame Rack:** Corrects lateral sway, vertical sag, twist, and diamond damage on Class 3–8 cab-chassis, dump trucks, and heavy tractors.
- **Spectrophotometer Fleet Livery Matching:** Digital PPG color camera matches national corporate fleet paint codes, municipal safety orange/yellow, and custom metallic finishes.
- **Aluminum, Steel & Fiberglass Fabrication:** MIG/TIG aluminum and steel welding for cracked subframes, dump aprons, box truck corner caps, and composite hoods.
- **Direct Commercial Insurance Coordination:** Dedicated heavy-truck estimators handle digital supplements, OEM parts sourcing, and direct billing with commercial carriers.

## Frequently Asked Questions
### Do you work directly with commercial truck insurance companies?
Yes. Our body shop estimators work directly with all major commercial trucking, towing, and municipal insurance providers—handling digital photo supplements, tear-down inspections, and direct billing to minimize your fleet downtime.

### Can you straighten a bent commercial truck frame without heating the rails?
Yes. Modern commercial heat-treated frame rails (80,000–120,000 PSI RBM) should never be overheated with torches. We use high-tonnage hydraulic frame towers and laser measuring systems to cold-straighten rails within OEM tolerances.

### How large of a truck fits inside your commercial paint booth?
Our 60-foot heated downdraft commercial paint booth easily accommodates long-wheelbase Class 8 heavy wreckers, rotators, 26-foot box trucks, tandem dump trucks, and fleet tractors.

### Can you match our company’s custom fleet paint code and install vinyl graphics?
Yes. We use PPG Commercial Performance coatings with digital spectrophotometer color matching, and can coordinate full fleet lettering, reflective DOT striping, and vinyl wraps before delivery.
