The security door is the first safety barrier that is essential for every household. It has both anti-theft and security functions. However, the security door on the market is very diverse, such as steel, steel-wood structure, stainless steel, aluminum alloy and copper. Its performance and quality have their own characteristics. How should we choose the most suitable security door for our own use? Let's take a look.
Steel: ordinary steel PK stainless steel
Ordinary steel security door - low price but hard line and poor decoration
Anti-theft index: ★ ★ ★
Steel security door is the most common security door product on the market. Generally, the security doors we see in the public household are mostly made of ordinary steel. The price of this kind of door is relatively low, but it is also very easy for the fish to be faked into a "pseudo-security door".

It can be divided into pure stainless steel door and stainless steel frame door. The former is relatively expensive to make, and the frame door is relatively popular. The middle is usually hollowed out with decorative flowers, and then double-sided glass. The color is lasting and bright, never born. Rust, slightly better.

Cobalt metal is mainly used for making alloy. Cobalt-based alloy is cobalt and chromium, tungsten, iron, nickel group made of one or more of the general term. Tool steel containing a certain amount of cobalt can significantly improve the wear resistance and cutting performance of steel. Stellite hardeners containing more than 50% cobalt do not lose their original hardness even when heated to 1000 ° C. Nowadays, these cemented carbides have become the most important material for use between gold cutting tools and aluminum. In this material, cobalt alloyed with other metal carbide grains together to make the alloy with higher toughness and reduce the sensitivity to impact, the alloy welding on the surface of the parts, the parts can make Life expectancy increased by 3-7 times.
