Semi chrome plating
Semi chrome is a term used to describe a type of chrome plating that falls between decorative chrome and hard chrome. Olymco, Inc. lists it among the finishing processes at its Canton, Ohio plant. The name alone does not settle the exact thickness, underplate, or appearance, so send the complete coating specification and the application.
What kind of part is semi chrome specified for?
For trim, hardware, or other visible components, identify the show surfaces and how the part will be handled in service. Where dimensions, wear, or corrosion matter, include measurable requirements alongside the desired appearance.
Semi chrome is heavier than a decorative flash, so it carries more of its own wear and corrosion duty, and light enough that it generally needs no post-plate grinding. Put the layer requirements and test criteria on the print rather than assuming the term defines them.
Describe whether the part is selected for its visible finish, handling resistance, or a functional working surface. Decorative chrome, nickel plating, and hard chrome have different requirements that should be resolved before ordering.
Identify any existing finish or appearance reference. Mark masking areas, critical dimensions, and acceptable rack contact points. Call (330) 452-2300 to arrange how to share drawings or reference parts.

Questions buyers ask about this process
What should I send if my print only says semi chrome?
Provide the application, desired appearance, and any known thickness or performance requirement. Ask Olymco to clarify the proposed coating system before ordering against an incomplete callout.
Is semi chrome the same as semi-bright nickel?
Do not treat the terms as interchangeable. Semi-bright nickel identifies a nickel layer. Confirm whether the drawing refers to nickel, chromium, or a complete coating system.
Can semi chrome replace hard chrome?
A substitution needs review against the functional requirement and drawing. If the part has a wear surface or needs dimensional build, provide those requirements and obtain approval for any process change.
Is it suitable for outdoor use?
Suitability depends on the specified coating system and exposure. Send the corrosion requirement and acceptance test, if defined, rather than relying on the process name to establish performance.
Will the part need grinding or polishing?
Preparation and final finishing depend on the incoming condition and required result. State the finished dimensions and appearance, and confirm which operations are included in the quote.
Can a long trim part be plated in one piece?
That depends on the part as much as the tank. Send complete dimensions, weight, geometry, and the required plated area for a fit review.
