Trenton's aging industrial and municipal infrastructure along the Delaware River corridor generates consistent demand for structural welding, equipment repair, and custom metal fabrication. Alpine Painting & Sandblasting Contractors provides welding and fabrication services integrated with our protective coating capability — giving Trenton's industrial and government clients a single contractor for structural metalwork and the corrosion protection that follows it. Our welders are certified, our safety program is award-winning, and our integrated workflow from weld to coat delivers superior results compared to separate contractors handling each scope independently.
