High-quality quartz sand serves as the primary raw material in the production of specialized optical glass. When combined with suitable additives, it allows for the creation of materials with exceptional optical properties. Rare earth elements, known for their high refractive index, low dispersion, and strong chemical stability, play a crucial role in manufacturing advanced optical components. These include lenses used in high-end cameras, camcorders, and telescopes, where precision and clarity are essential. For instance, bismuth-based glass containing 36% yttrium oxide (Y₂O₃) and 40% boron oxide (B₂O₃) is widely used in the production of high-performance camera lenses and periscope optics due to its superior light transmission and durability. Additionally, certain rare earth elements possess radiation-resistant properties, making them ideal for producing protective glass used in environments exposed to high levels of radiation, such as in scientific research or medical imaging equipment. This versatility ensures that rare earth-infused glass remains an essential component in modern optical and industrial applications.

In terms of appearance, aluminum entrance doors have strong plasticity and can present rich and diverse colors and textures, such as wood grain and stone grain, through various surface treatment processes. They can match different architectural styles and interior decoration styles, highlighting the unique taste and temperament of your home.
In terms of durability, aluminum materials have good corrosion resistance and weather resistance, are not easily affected by natural factors such as sunlight, rain, humidity, etc., and will not deform, fade, crack, etc., and can still maintain good appearance and performance after long-term use, reducing the cost of maintenance and replacement.
Moreover, aluminum entrance doors also have good heat insulation and sound insulation performance, which can effectively block outdoor noise and heat transfer, creating a quiet and comfortable indoor environment for you.
Armored doors are made of sturdy steel structures (called armor systems) in the middle of the door leaf,
The double-sided surface is covered with different solid materials for decoration.
Armored doors originated in Europe, and their main feature is their armor system (the middle of the door leaf)
Using a sturdy inner liner structure, and then using different surface coverings for decoration
The entire door can adapt to any decoration style; The materials that can be used on the surface are:,
