1. Glass: Generally, high-definition float glass is chosen, which has good flatness and low distortion, allowing for clear imaging. High-quality glass also has a certain strength and impact resistance, making it less likely to break.2. Reflective Coating: There are mainly two types: silver mirrors and aluminium mirrors. Silver mirrors use silver as the plating component, offering excellent refractive performance, high brightness, and clear and lifelike imaging with good moisture resistance, but they are more expensive; aluminium mirrors are made from metallic aluminium and are relatively cheaper, although they are slightly inferior in brightness and refractive performance.3. Frame Materials: Common options include aluminium alloy, stainless steel, and wood. Aluminium alloy frames are lightweight and durable, and are not prone to rust; stainless steel frames are strong and solid, with excellent corrosion resistance; wooden frames provide a natural warm texture, complementing various decoration styles.
