FIVE CORE PROPERTIES
Corrosion resistance, weldability and formability:
technical advantages across manufacturing processes
From corrosion protection to welding, forming and fastening. Ceramic zinc composite plating connects your manufacturing process with the requirements of the service environment.
Post-Plating Welding
The thin plated layer supports post-plating welding. Welding parameters and weld-area post-treatment are specified for the joining method.
Bending, Roll Grooving and Threaded Assembly
An average plating thickness of approximately 8 µm supports bending, roll grooving and threaded assembly. Post-plating fabrication quality is controlled to the part geometry and dimensional tolerances.
Chemical and Process Resource Management
Chemical-substance testing and production parameters guide material and process management. Energy and water use are compared on an equivalent production basis.
Rack and Barrel Plating for Your Components
We select rack or barrel processing and define production parameters for the component size, geometry and throughput.
PRODUCTION PROCESS
Production processes
tailored to component geometry
Rack plating secures components on purpose-designed fixtures. Barrel plating processes small components in rotating barrels. We select the process for the component geometry and production throughput.
Watch the Rack Line Rack Line
Components are secured on plating racks designed for their size and geometry.

Small components are batch-plated in rotating barrels.
INNOZINC ANSWERS
Frequently Asked Questions
Product selection:
specifications, fabrication and samples
How do Innozinc and Innozinc-h differ?
Standard-grade Innozinc has a representative maximum SST range of 720–1,000 hr; high-corrosion-resistance Innozinc-h has a range of 1,500–2,000 hr. Grade selection reflects the service environment and manufacturing and assembly requirements.
Can parts be welded or fabricated after plating?
Innozinc supports post-plating welding, bending and roll grooving. Sample evaluation reflects the welding method, forming radius and dimensional tolerances, and establishes post-treatment conditions for the fabricated areas.
What is the coating thickness?
The stated average thickness for standard Innozinc is approximately 8 µm. Actual thickness can vary with substrate geometry, pretreatment and process conditions.
Does SST 720–1,000 hr indicate service life?
SST measures corrosion resistance under controlled salt spray conditions. Product specifications include the specimen substrate, pretreatment, thickness and white- and red-rust acceptance criteria. SST is a laboratory performance indicator, distinct from years of service.
How do I request samples?
Provide the substrate, dimensions, quantity, drawings or photos, and service environment. Our team will confirm the plating specification, sample quantity, cost and schedule.
