Thread precision and corrosion resistance
Plating specifications are developed for the geometry and dimensional tolerances of bolts, nuts and other threaded fasteners.

Combining corrosion resistance and formability
with ceramic zinc composite plating
Innozinc is KEMP's standard Ceramic Galvanizing grade.
Zinc and an inorganic ceramic film form a composite structure that enhances corrosion resistance
while supporting post-plating welding, fabrication and topcoating.

APPLICATION ENGINEERING
Engineered for post-plating fabrication quality:
Standard-grade Ceramic Galvanizing
Thin-film adhesion and formability support
threaded assembly, bending and roll grooving.
Post-plating forming and joining
We configure coating and post-treatment parameters for the bending, roll-grooving and welding operations used on pipe fittings and brackets.

Salt spray testing:
corrosion behavior over time
Specimen photographs document the progression of surface changes
during salt spray exposure.
KEMP specimen photographs record the surfaces before testing and at 120, 360 and 480 hr. The standard Innozinc product specification is SST 720–1,000 hr; the photographs retain the actual observation times for these specimens.

Frequently Asked Questions
Product selection:
specifications, fabrication and samples
How do Innozinc and Innozinc-h differ?
Standard Innozinc has a representative SST specification of 720–1,000 hr; high-corrosion-resistance Innozinc-h has a representative specification 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.
