What are the advantages of the wavy plastic handle of the end-cap paint roller rack and the materials used?

The wavy design of the wavy plastic handle of the end-cap paint roller rack increases the contact area between the handle and the palm, and provides a better grip through its concave and convex texture, reducing hand fatigue during long-term use. This design can effectively prevent slippage caused by paint, coatings or sweating hands during use, ensuring the safety and stability of operation. The wavy handle is often ergonomic and can naturally fit the contour of the hand, making the operation smoother and more labor-saving. The wavy design is not only beautiful, but also can enhance the structural strength of the handle to a certain extent, improve its durability and extend its service life.
The galvanized layer tightly covers the surface of the steel, forming a dense metal barrier, which effectively isolates the steel from direct contact with humid air and corrosive media, thereby greatly slowing down the oxidation reaction rate of the steel and preventing rust and corrosion. A potential difference is formed between the galvanized layer and the steel. When the galvanized layer is damaged, the zinc layer will corrode first as the anode, while the steel will be protected as the cathode. This "sacrificial anode" electrochemical protection mechanism further extends the service life of the steel.
The high strength and hardness of steel enable the paint roller rack to withstand a large workload, whether it is mounting a heavy paint roller or an unexpected impact that may be encountered during use, it can maintain the stability and integrity of the structure. Steel has good plasticity and processability, and can be processed into various complex shapes and sizes through cold processing, hot processing and other methods to meet the diverse needs of paint roller rack design. The standardized production process of steel makes it easy to achieve large-scale batch production. At the same time, advanced processing technology also makes customized production possible to meet the personalized needs of different users.
The density of plastic is much lower than that of metal, so the plastic handle is lighter than the metal handle, which reduces the weight of the overall product, making it easier and more convenient for users to use or carry it for a long time. As a non-conductive material, plastic has good insulation properties, which provides additional safety protection in situations where electrical environments may be involved or users are worried about electric shock. Although paint roller racks usually do not involve electrical applications, this feature still brings psychological security to users. The relatively low cost of plastic materials helps to reduce the overall cost of the product, making the product more competitive in the market. At the same time, the manufacturing process of the plastic handle is relatively simple and the production efficiency is high, which also helps to control production costs.
The wavy plastic handle of the end-cap paint roller rack and the materials used together bring many advantages to the product, such as comfort, safety, durability and cost-effectiveness.
