All Finishes

ZnNi (Alkaline)

Explore the advantages of Alkaline Zinc plating, a process utilizing eco-friendly alkaline solutions. Offering superior corrosion resistance among Zinc Alloy Platings, it is ideal for outdoor use and components exposed to harsh environments. The ductile coating ensures excellent adhesion, even after post-plate forming or bending, and exhibits remarkable corrosion resistance in high-temperature conditions. Known for its heat-resistant properties, this method provides prolonged protection, maintaining corrosion resistance under extreme temperatures. The thin, smooth, and uniform coating is suitable for threaded parts or components with tight dimensional tolerances, making it an excellent choice for intricate shapes. With a proven track record of exceeding 1000 to 1200 hours in a salt spray test, Alkaline Zinc plating stands out for its reliability and performance.

Zn-Fe (Zinc-Iron)

Uncover the benefits of Zn-Fe, also known as zinc-iron plating, a process that deposits a layer of zinc-iron alloy onto metal substrates to enhance corrosion resistance and impart additional desirable properties. Renowned for its solid weldability and good ductility, Zn-Fe ensures components maintain excellent surface appearance. Its even distribution, suitable for both even-edged and irregular components, sets it apart, along with superior lubricity and a high level of hardness. With a remarkable salt spray resistance exceeding 480 hours, Zn-Fe is an excellent choice for intricate and complicated shapes, offering reliable protection and lasting performance.

Tin (Sn)

Step into the realm of tin plating, a process that involves depositing a protective layer of tin onto metal substrates, offering valuable properties such as corrosion resistance, excellent solderability, and more. Tin, known for its soft, malleable, and silvery-white characteristics, is not only abundant but also a cost-effective solution. Beyond its affordability, tin plating provides a whitish-gray color ideal for achieving a dull or matte appearance. However, when a touch of luster is desired, it can effortlessly transform into a shiny, metallic finish. In addition to its aesthetic versatility, tin plating ensures reliable protection against corrosion and exhibits good conductivity, making it a multifaceted choice for various applications.

Chromate Conversion Coating (CCC)

Immerse aluminum and its alloys in a controlled chromic acid bath, and witness a chemical conversion reaction unfold at the metal's surface. The result? A sophisticated, non-crystalline, and impermeable coating, featuring a thin aluminum oxide film enriched with chromates and dichromates. This coating acts as a versatile shield, offering corrosion protection and boosting resistance for both bare and painted surfaces. Not stopping there, it enhances the adhesion of paint or primer coatings, providing not just protection but also an attractive decorative finish. Tailored for electronic components, CCC delivers a comprehensive solution, harmonizing corrosion protection with aesthetic appeal.

Electroless Nickel Coating

Experience the deposition of a nickel-alloy coating through chemical reduction, a process distinct from traditional electroplating as it doesn't require an electric current. Our Electroless Nickel Coating offers excellent corrosion protection, forming a uniformly thick layer across the entire substrate, including slots, holes, and inside walls of tubing. This process ensures not only robust corrosion resistance but also imparts good hardness, wear resistance, and bending properties to the coated surfaces.

Surface Conditioning

Experience a meticulous process of controlled micro-attack and impurities removal, ensuring a thorough cleaning of the substrate. Our method removes dirt, grease, oxides, and other contaminants, creating an ideal surface for enhanced adhesion in subsequent processes. This meticulous technique results in an excellent finish, particularly beneficial for electronic components.


Dive into the world of anodizing, an electrochemical oxidation process that transforms metals and alloys, particularly aluminum, into a robust and wear-resistant masterpiece. Through the controlled application of current, an oxide film forms on the aluminum surface, ushering in a range of benefits. Experience enhanced hardness as the process generates a thick and resilient coating, significantly boosting wear resistance. Anodizing excels in delivering precise thickness control, ensuring uniformity and consistency throughout. This method isn't just about toughness; it also enhances dielectric strength, making it ideal for applications demanding electrical insulation. Plus, with its tight tolerance capabilities, anodizing caters to specific engineering requirements, making it a versatile and reliable choice.

Hard Anodized

Embark on a journey of durability with Hard Anodized finishes. This electrochemical process immerses aluminum in an acidic electrolyte, subjecting it to an electrical current that transforms its surface. The "hard" in Hard Anodized signifies a thicker, more robust oxide layer achieved through an extended and controlled anodizing process. The result? A surface that's not only significantly harder than untreated aluminum but also scratch-resistant and highly durable. Tailored for environments demanding high abrasion or corrosion resistance, Hard Anodized shines where functionality takes precedence over cosmetics. With coatings typically 0.002” thick and available as class 1 (non-dyed), it provides exceptional abrasion resistance that won't peel or come off, all in an environmentally friendly package.
