Mechanical Galvanizing Services for Long-Lasting Protection

Home > Mechanical Galvanizing

Choose mechanical galvanizing when you need dependable zinc protection without introducing unnecessary heat, heavy coating buildup, or extra thread work. We provide mechanical galvanizing services from our Trenton, New Jersey facility for manufacturers, fastener companies, OEMs, and industrial customers throughout the Northeast and across key markets including Illinois, Texas, and Tennessee.

Our process applies a mechanically deposited zinc coating to fasteners, threaded components, hardware, and suitable steel parts where corrosion protection, coating control, and part integrity matter.

What Is Mechanical Galvanizing?

Mechanical galvanizing is a room-temperature process that deposits zinc onto iron and steel components without electrical current.

Cleaned parts are placed in a rotating barrel with zinc powder, glass bead impact media, and a chemical promoter. Controlled mechanical action bonds zinc particles to the prepared metal surface.

The process is well suited to fasteners, threaded parts, heat-treated components, and other small steel hardware. Coatings can also be applied to requirements such as ASTM B695.

For suitable applications, it provides an efficient and environmentally benign alternative to other zinc-coating methods without high-temperature processing.

Benefits of Mechanical Galvanizing

Corrosion Protection
Zinc protects the underlying steel from rust and weather exposure.

Controlled Coating Thickness
Limits buildup on threads, recesses, and close-fitting parts.

Room-Temperature Processing
Protects heat-treated parts without high-temperature exposure.

Reduced Hydrogen Embrittlement Concern
Suitable for high-strength steel where electrolytic coating raises hydrogen embrittlement concerns.

Parts Suited to Mechanical Galvanizing

We process small steel components where corrosion resistance, coating consistency, and part fit are important.

Fasteners: Bolts, screws, nuts, washers, and other fasteners requiring mechanical zinc protection.

Threaded Components: Threaded studs and similar parts where coating buildup can interfere with mating surfaces.

Heat-Treated Parts: Suitable hardened and high-strength steel components that benefit from room-temperature processing.

Small Industrial Hardware: Stampings, brackets, fittings, and other process-compatible steel parts.

Our Trenton facility serves customers sourcing fasteners and threaded studs in New Jersey as well as components shipped from other service areas.

Our Mechanical Galvanizing Process

1. Clean and Prepare the Parts
Remove oils, rust, scale, and surface contaminants that could interfere with coating adhesion.

2. Load the Components
Place the parts in the processing barrel with glass bead media and the required process materials.

3. Mechanically Deposit the Zinc
Introduce zinc powder and use controlled barrel action to bond the coating to the prepared surface.

4. Finish and Inspect
Apply the specified post-treatment where required and check the finished coating against the job requirements.

Common Industries and Applications

Construction & Infrastructure: Bolts, fasteners, threaded hardware, and steel components requiring corrosion protection in demanding service conditions.

Automotive & Industrial Equipment: Small engineered components where coating thickness, fit, and part integrity need to remain controlled.

Electrical Transmission: Hardware used outdoors where corrosion resistance and consistent zinc protection are important.

Agriculture & Marine: Steel hardware and components exposed to moisture, weather, dirt, and other corrosive conditions.

Military & Specialized Fasteners: High-strength and specification-driven fastener applications requiring careful coating selection and control.

Meet the Coating Requirement on the Drawing

Send us the part drawing, material, required coating thickness, applicable specification, quantity, and any post-treatment requirements.

Our metal-finishing experience, cutting-edge facilities, and established process controls allow us to handle demanding customer requirements and work aligned with some of the most demanding industry standards.

Mechanical galvanizing can be processed to applicable ASTM B695 requirements along with customer-specific coating and finish specifications.

Choose the Right Mechanical Finish

Mechanical galvanizing uses zinc. If your drawing calls for another mechanically deposited metal, ask about our related mechanical plating capabilities, including cadmium and tin.

We support customers requiring mechanical cadmium for Chicago and Texas applications, as well as mechanical tin for projects serving Memphis and other markets. For the right part, mechanical processing can also be a more affordable option when controlled coating and reduced secondary thread work eliminate additional processing steps.

Send Us Your Mechanical Galvanizing Requirements

Send your part type, material, dimensions, quantity, drawing or specification, required coating thickness, and post-treatment requirements to our Trenton team. We will review the application and determine the appropriate mechanical finishing approach for your parts.

Frequently Asked Questions

What information should I provide for a mechanical galvanizing quote?
Send the part material, dimensions, quantity, drawing if available, required coating thickness, applicable specification, and any conversion coating or lubricant requirements.

What size parts can be mechanically galvanized?
Part suitability depends on weight, dimensions, geometry, and processing requirements. Send us the part details so we can confirm whether the component fits our mechanical galvanizing capabilities.

Can mechanical galvanizing be applied to a specific coating thickness?
Yes. Coating thickness can be controlled according to the applicable specification and requirements shown on the drawing or purchase order.

What should I include on a drawing or purchase order?
Include the base material, coating specification, required thickness or class, finish, post-treatment, and any customer-specific requirements.

Can mechanically galvanized parts receive conversion coatings or lubricants?
Yes. Compatible conversion coatings, sealers, dyes, and lubricants may be available depending on the coating system, component, and application.

Do you accept mechanical galvanizing work from outside New Jersey?
Yes. Our operation is based in Trenton, New Jersey, and serves industrial customers in New Jersey as well as markets including Illinois, Texas, Tennessee, New York, Connecticut, Massachusetts, and other areas.

10 GOOD REASONS FOR
MECHANICAL GALVANIZING
Excellent Adhesion and controlled uniformity of coating thickness: Sacrificial metal coating is applied with coverage to all surfaces of the part to the corners recesses, threaded areas as well as to the flat, more exposed regions.
GOOD REASONS FOR MECHANICAL
PLATING
The most important reason: The most important reason for mechanical plating is the assurance of product reliability through the elimination of hydrogen embrittlement. Mechanical plating is he method preferred by many engineers for hardened .
