Different Finish of Wardrobe Tubes

The tubes used in wardrobes (commonly known as hanging rods, mostly made of aluminum alloy, stainless steel, iron, etc.) adopt surface treatment processes mainly to prevent rust, resist wear and enhance aesthetics. There are significant differences in texture and performance among different processes, with the common ones listed as follows:

1. Electrophoretic CoatingThis is a commonly used process for aluminum alloy hanging rods. A uniform and dense paint film is formed on the metal surface through electrophoretic technology, featuring strong adhesion, resistance to chipping and scratching, as well as a soft luster and delicate touch. It offers a wide range of color options, such as black, white and champagne, and has better corrosion resistance than ordinary spraying.

2. Powder CoatingPowder coatings are electrostatically adsorbed onto the metal surface and then cured at high temperatures to form a coating layer. This coating is thicker than electrophoretic coating, with excellent wear resistance, scratch resistance and weather resistance. Its surface can be finished in various textures, including matte, semi-matte and high-gloss, and comes in a rich variety of colors to match different wardrobe styles. The drawback is that if the coating is damaged, rusting tends to start from the damaged area.

3. AnodizingPrimarily applicable to aluminum alloy materials, this is an electrochemical oxidation treatment. An oxide film is formed on the metal surface, which is characterized by high hardness, wear resistance and corrosion resistance. Moreover, the oxide film can be dyed, with common colors including silver, gold and black. The treated surface has a metallic texture, a cool touch and is resistant to fading, making it a relatively high-end surface treatment method.

4. Chrome Plating / Galvanizing

Chrome Plating: Mostly used for iron or stainless steel materials, a bright chrome layer is formed on the surface, boasting a tough texture, high reflectivity, good rust resistance, as well as wear and scratch resistance. 

Galvanizing: Its main function is rust prevention. The zinc layer will corrode preferentially over the base material, thereby protecting the internal metal. The galvanized surface is silvery gray with moderate glossiness, and is often used as an undercoating before other processes to improve aesthetics.

5. PolishingMostly applied to stainless steel materials, mechanical grinding is used to make the surface smooth and shiny, presenting the inherent metallic texture of stainless steel with a minimalist and elegant look. Polishing is divided into mirror polishing (with strong reflective effect) and wire drawing polishing (with fine filamentary texture on the surface, which does not easily show fingerprints). The latter is more commonly used for wardrobe hanging rods.

6. Spray PaintingThis is a relatively basic surface treatment with low cost. Paint is directly sprayed onto the metal surface with a wide range of color choices, but the paint film has weaker adhesion and wear resistance compared to electrophoretic coating and powder coating. It is prone to chipping and fading after long-term use, and is mostly used for budget-friendly wardrobe products.
