Service
Stop paying twice: once to remove rust, again to repair the substrate sandblasting eroded. Our pulsed fiber laser vaporizes rust, scale, and oxide to bare metal without any contact with the surface underneath.

Sandblasting removes rust, but it also removes base metal. Every pass erodes the substrate, changes tolerances, and creates surface pitting that traps moisture and accelerates re-rusting. On precision components, this dimensional change is unacceptable. On structural steel, the pitting creates stress concentrators that weaken the member.
Manual grinding is slower (5-10 sq ft/hour vs. 50 sq ft/hour for laser) and creates sparks that are prohibited near fuel systems, in refineries, and in confined spaces. The vibration causes operator fatigue and injury. The noise exceeds 85 dB, triggering OSHA hearing protection requirements.
Chemical rust removers require hours of dwell time, generate hazardous liquid waste, and leave residue that interferes with subsequent coating adhesion. On large surfaces (structural steel, ship hulls, industrial equipment), the labor cost of applying and removing chemicals exceeds the cost of laser cleaning.
Strip heavy rust at up to 50 sq ft per hour. Hand-grinding covers 5-10 sq ft/hr with substrate damage. Chemical stripping requires hours of dwell time before cleaning even begins.
Laser parameters are matched to the oxide layer and substrate during test cleaning. When the process window is properly established, laser cleaning can minimize pitting, erosion, and dimensional impact compared with aggressive abrasive methods.
No blast media to purchase, contain, or dispose of. This avoids spent blast-media disposal. Removed rust, coatings, captured particulate, and filters may still require characterization, TCLP testing, manifests, or regulated disposal based on the material and project requirements.
Our pulsed fiber laser uses short bursts of energy to remove iron oxide in controlled passes. Airborne particulate is managed with source capture and HEPA filtration. We adjust and verify parameters on a test area to manage heat input and confirm the base-metal response.
We adjust pulse frequency, power density, and scan speed for each substrate and rust grade. Light flash rust on stainless steel requires different parameters than heavy scale on cast iron. This calibration is what separates professional laser cleaning from the consumer-grade units sold online.
Throughput on Grade B rust (per ISO 8501-1) ranges from 20-50 sq ft per hour depending on laser power class. Our systems handle everything from spot cleaning a single weld joint to processing thousands of square feet of structural steel per day.

How fast is laser rust removal compared to sandblasting?
Laser removes rust at 20-50 sq ft per hour depending on rust severity and laser power. Sandblasting is comparable in speed but requires containment setup, media purchase, and post-job cleanup that add hours to the total project time. Manual grinding covers 5-10 sq ft per hour.
Does laser rust removal damage the base metal?
No. The laser is tuned to the absorption wavelength of iron oxide. The base metal (steel, aluminum, cast iron) reflects the laser energy and remains dimensionally unchanged. This is verified by surface profilometry before and after cleaning.
What types of rust can laser cleaning remove?
All grades per ISO 8501-1: Grade A (mill scale), Grade B (rusting mill scale), Grade C (rusted with pitting), and Grade D (rusted with visible pitting and grooving). We also remove flash rust, weld discoloration, and heat-affected zone oxides.
Can laser rust removal be used near fuel systems or in confined spaces?
Potentially, but only after a site-specific hazard review. Fuel-adjacent, confined-space, or classified-area work can require controls for ignition sources, ventilation, atmosphere testing, respiratory hazards, laser exposure, permits, and equipment suitability. The work plan must be approved for the actual location.
After rust removal, laser-cleaned surfaces are ready for coating, welding, or bonding.
