PVD vs Polished: Best Stainless Steel Faucet Surface Guide

1. Mirror polishing: a dazzling and fleeting visual feast

• stainless steel faucets
• is far from a simple “coating”. It is a fusion of aesthetics and technology, and it is also the cornerstone of durability and safety. From the dazzling mirror polishing to the strong and corrosion-resistant PVD coating, each process profoundly shapes the visual charm, tactile experience and service life of the product. This article deeply analyzes the 6 core surface treatment technologies (polishing, sandblasting, brushing, PVD, electroplating, spraying), revealing their process secrets, performance differences and applicable scenarios, to help you accurately match your needs in home improvement upgrades or purchasing decisions, and create a durable quality kitchen and bathroom space.
• Core of the process: The mechanical friction of the sanding belt (100-1200 mesh, step by step), hemp wheel, and cloth wheel, combined with ultrasonic cleaning, achieves the ultimate flatness and light reflection of the stainless steel surface.
• Advantages: Comparable to the luxurious mirror effect of traditional water electroplating, instantly improve the texture and brightness of the space.

2. Sandblasting: pragmatism under rough texture

• Fatal weakness: The surface hardness is insufficient (HV is only about 200-300), and it is easy to leave hair marks after daily wiping; the purity of the substrate is strict, and defects are nowhere to hide. It can be called a “delicate beauty”.
• Suitable choice: Pursuing extreme light perception and non-high-frequency contact areas (such as high-end display bathrooms, hotel mirror decoration accessories).
• Technology essence: High-speed jet abrasives (such as diamond sand, glass beads) hit the surface to form uniform micron-level pits, obtaining a matte texture and specific roughness. The appearance parts need to be pre-polished to ensure the flatness of the foundation .
• Core advantages: Effectivelycover minor substrate defects; matte surfaceresistant to minor scratches; unique touch adds a modern industrial style.

• Limitations: The surface is still relatively “open” and less hydrophobic than the closed coating; long-term contact with grease may penetrate into the micropores.
• Best scenarios: Public spaces, industrial-style home decoration, users who pursue low-key practicality and easy maintenance.
• Technology essence: Use a sanding belt or nylon wheel with a specific mesh to rub at a uniform speed in a single direction to form a continuous, uniform, and decorative straight line pattern.
• Significant advantages: The texture itself cancleverly cover daily use scratches; more resistant to fingerprints than polished surfaces; delicate texture with both modern and classic charm.
• Key points to know: The protectiveness still depends on the stainless steel body, without an additional reinforcement layer; the splicing of textures in different directions requires extremely high process consistency.
• Classic choice: The main force of household kitchen faucets, perfectly balancing beauty, stain resistance and cost-effectiveness.
• Technological leap: Ions bombard the target material in a vacuum chamber, so that metals such as titanium and zirconium or nitrides and carbides are deposited on the surface in an atomic state, forming an ultra-thin (micron-level) but exceptionally dense and hard ceramic coating .

3. Brushed texture: balance between the beauty of order and durability

• Peak performance:
• Extreme hardness: HV can reach 1000+, wear resistance and scratch resistance are unmatched.
• Unrivaled corrosion resistance: Completely isolate the substrate from the corrosive medium.
• Color revolution: Stably achieve rich metallic colors such as champagne gold, gun black, rose gold, never discolor or fade.
• Cost considerations: Equipment and process costs are significantly higher than traditional methods; color selection is limited by target materials and process windows.
• High-end positioning: The first choice for pursuing extreme durability, personalized colors, and flagship products.
• Traditional process: Electrodeposit nickel layer + chromium layer on a copper/zinc alloy substrate. Although commonly used for non-stainless steel faucets, it is sometimes used for stainless steel accessories decoration.

• Relative advantages: Lower cost; standard “chrome plating” bright surface can be obtained.
• Stainless steel application flaws:
• Adhesion crisis: The chromium layer is inherently weak in bonding with stainless steel, easy to bubble and fall off.
• Environmental protection pressure: Traditional hexavalent chromium electroplating is seriously polluting and faces strict global restrictions .
• Double-layer risk: Damage to the coating will cause the stainless steel and the coating to form an electrochemical corrosion cell, accelerating the destruction.
• Industry trend: Stainless steel body + PVD or high-quality brushing/sandblasting are rapidly replacing water electroplating solutions.
• Modern evolution: Adopt environmentally friendly water-based paint (such as fluorocarbon, acrylic), attached by electrostatic spraying or UV curing technology.

Summary:

Unique value: PVD покритие: Технологията дава възможност и постига максимална защита Unlimited colors: Break through the limitations of metal colors, Achieve any Pantone color and special effects.

1. Excellent barrier: Provide good physical isolation to protect the stainless steel substrate.
2. Environmentally friendly: Water-based systems significantly reduce VOC emissions.
3. Performance boundary: The hardness (generally HV<5) and wear resistance of organic coatingsare far lower than PVD or metal itself; long-term hot and humid environment tests aging resistance.
4. Creative stage: Children’s bathroom, personalized customization space, and product lines that focus on environmental certification.
5. The “face engineering” of

is actually a precise collaboration of material science and surface engineering:

• Mirror polishing is dazzling, but requires careful care;
• Sandblasting/brushing finds a pragmatic balance between durability and aesthetics in the matte order;
• PVD coating reaches the peak of hardness, corrosion resistance and color stability with technological breakthroughs;
• Hydrochromium plating is a compatibility trap for stainless steel, and there is a great risk of fading and peeling;

Environmentally friendly spraying opens up a new path for personalized color and safety and environmental protection, but wear resistance is its shortcoming.
