Expert Coating Application & Waterproofing Services

Coating application is the process of applying a protective or performance-enhancing layer to a part’s surface. In industrial settings, coatings may improve wear resistance, corrosion resistance, hardness, surface finish, or part life. Parkway-Kew Corporation uses methods such as HVOF, plasma spray, metallizing, fuse welding, and submerged arc welding depending on the material, geometry, and operating conditions.

Waterproof or protective coatings are applied by first preparing the surface so the coating can bond properly. The selected coating material is then applied using the appropriate technology, such as spray, weld overlay, or metallizing, followed by finishing or grinding when required. For industrial parts, coating choice depends on exposure, wear, corrosion, heat, and dimensional requirements.

Parkway-Kew Corporation applies and works with materials including ceramics, tungsten carbide, chrome oxide, aluminum, stainless, zinc, nickel chrome boron alloys, and proprietary systems such as PK-730. The best material depends on whether the component needs abrasion resistance, corrosion resistance, smooth wire contact, crack-free deposits, or maximum service life under harsh operating conditions.

HVOF, or High Velocity Oxygen Fuel coating, propels alloy powder at extremely high speeds so it impacts the substrate and builds a hard, dense coating. The result is a nearly defect-free surface with strong wear and corrosion resistance. Parkway-Kew introduced HVOF coating for wire drawing blocks in 1989 and applies multiple PK alloy systems.

Yes. Parkway-Kew Corporation supports worn industrial components through rebuilding, hardsurfacing, Restore & Grind repairs, and precision machining. For wire drawing blocks, the Restore & Grind process can fill only the drawline area and blend it into the original coating, allowing lower-cost repairs multiple times before a full new coating is needed.

Coating performance depends on the part material, coating alloy, surface preparation, operating load, corrosion exposure, and maintenance conditions. Parkway-Kew’s coatings are designed to extend wear life and reduce downtime in demanding applications. Some rebuilt components, such as urethane coated festoon wheels, have demonstrated lifespans two to three years longer than OEM wheels.

Industries served include wire mills, oil and gas fracking companies, shipping terminals, heavy equipment manufacturers, earth-moving equipment operations, and container loading or unloading facilities. Parkway-Kew’s coating and rebuilding services are especially useful for high-wear components such as wire drawing blocks, capstans, plungers, pulleys, sheaves, tuner rolls, and guide devices.

Parkway-Kew Corporation is available Mondays through Fridays from 8:00 am to 5:00 pm. Project timing depends on the part type, coating method, machining requirements, and whether the work involves rebuilding, grinding, or a full coating application. The team can review your component details and recommend the most efficient service path.
