Custom Bathroom Double Swivel towel rail Manufacturers

What are the surface treatment processes for bathroom double swivel towel rail?

Electroplating: a classic and widely used process
Electroplating is a technology that deposits metal ions on the surface of a product through an electric current. It is often used on double-arm towel racks made of stainless steel or zinc alloy. Common electroplating layers includechrome, nickel, etc.
Advantages: Bright and smooth surface, strong corrosion resistance, and high-quality texture;
Applicable scenarios: Suitable for high-end home decoration and hotel projects;
Domus process features: Our company uses multi-layer chrome plating technology to ensure that the electroplating layer has strong adhesion, and can pass the salt spray test for more than 72 hours, meeting the high standards of European and American customers.
Brushed Finish: a representative of modern minimalist style
Brushing is to evenly scratch the metal surface through mechanical means to form a fine texture.
Advantages: Effectively prevent fingerprints and water stains, delicate touch;
Aesthetic effect: Matte and non-reflective, reflecting the minimalist design language;
Domus manufacturing strength: We have our own brushed and polished stations to ensure uniform and consistent textures, which are widely used in European minimalist style product lines.
Spraying and sandblasting (Powder Coating / Sandblasting): Enhance texture and personality expression
Spraying is a process that uses a high-pressure spray gun to evenly cover the surface with powder or paint, and then solidifies at high temperature after electrostatic adsorption. Sandblasting creates a micro-rough texture on the surface.
Advantages: It can achieve a variety of colors and textures (matte black, white, gray, etc.), and has strong scratch resistance;
Breadth of application: It has been very popular in the Australian and North American markets in recent years;
Domus solution: For customized projects, we provide personalized color spraying services, and use environmentally friendly coatings that comply with RoHS standards.
PVD vacuum coating (Physical Vapor Deposition): high-end surface technology
PVD is a high-end surface treatment method that evaporates metal materials in a vacuum and deposits them on the surface of the product.
Advantages: Super wear resistance, excellent oxidation resistance, stable color;
Color performance: Rose gold, gun color, titanium black and other trendy colors;
Domus technical strength: In-depth cooperation with professional PVD partner factories to ensure that the high-end series of towel racks have full color and long-term non-fading, and are widely used in luxury residential and commercial bathroom projects.
Stainless Steel Passivation: Give full play to the advantages of the material itself
For towel rack products made of 304 or 316 stainless steel, after passivation treatment, a dense protective film can be formed to further enhance its anti-corrosion performance.
Advantages: Maintaining the original metal texture, in line with the trend of minimalist and environmentally friendly design;
Domus application scenarios: We provide two types of stainless steel surfaces, standard and mirror polished, with passivation treatment, especially suitable for the market in humid coastal areas.

Is there a risk of rust or oxidation in a humid environment for bathroom double swivel towel rails?

Challenges of humid environments to metal towel racks
The average humidity in the bathroom environment is usually between 60% and 90%. Coupled with the long-term influence of hot water vapor, it is very easy to cause water droplets, condensation and even acidic and alkaline chemical residues on the metal surface. If the material selection is improper or the surface treatment process is weak, the surface of the towel rack will be oxidized, corroded or rusted, which will not only affect the appearance, but also shorten the product life.
This problem is particularly prominent for users who install in coastal cities or high humidity and high salt areas (such as coastal cities in Australia, coastal ports in South America, etc.).
Material selection: Domus' first line of defense
Ningbo Domus Hardware Co., Ltd. adheres to the concept of "material first" in the early stage of product development. The main substrates we use include:
304 stainless steel: has excellent corrosion resistance and oxidation resistance, and is currently the mainstream material for high-end bathroom hardware.
Aluminum alloy: light weight, naturally not easy to rust, suitable for anodizing, and modern appearance.
Zinc alloy (Zamak): high strength, suitable for precision casting, and excellent corrosion resistance after electroplating.
We conduct strict screening in the material procurement process to ensure that each batch of raw materials meets the environmental protection requirements of the EU RoHS, REACH, etc., and ensure that the basic corrosion resistance meets the standards.
Surface treatment: core technology for rust and oxidation resistance
In addition to high-quality materials, Domus pays more attention to the design of the surface protective layer of the product, which is the key to anti-rust:
1. Electroplating
The use of multi-layer nickel plating + chrome plating technology not only makes the product surface as bright as a mirror, but also forms a dense protective layer to block the erosion of air and water vapor on the substrate. Our electroplating layer has passed the neutral salt spray test (NSS) for more than 72 hours and is widely used in export to the European and South American markets.
2. Brushed + transparent protective film
The brushed treatment can form a uniform texture on the surface and reduce the residual oxidation fingerprints. Covered with a polymer transparent protective film, it can effectively isolate moisture and delay metal aging.
3. PVD vacuum coating (Physical Vapor Deposition)
In high-end customized products, we use PVD coating technology to make the products present high-end colors such as gold, titanium black, rose gold, etc., and have extremely high wear resistance and corrosion resistance. Tests show that the PVD surface is more resistant to salt spray corrosion by more than 30% than traditional electroplating.
