Like many of our necessities, our locks have a very large rigid demand. The rapid development of the lock industry is just like the sunrise industry. In recent years, China's hardware lock industry has grown steadily at an annual growth rate of 15%. Up to 180 billion yuan*** and above, exports reached more than 8 billion US dollars. It accounts for about one-third of China's total light industry exports and ranks in the top three in light industry export rankings.

At least 95% of them are private enterprises. Private enterprises have become the main force in the development of China's hardware lock industry. China has become the world's largest producer and consumer of locks. And there are about 1,000 lock manufacturers with an annual sales of more than 5 million yuan. The profits mainly come from exports, and the industrial bases are concentrated in Guangdong, Zhejiang, and Shandong. Among them, Wenzhou, Zhejiang enjoys the reputation of “China's lock capital”, Xiaolan Town, Zhongshan City, Guangdong Province, known as the “South lock city”.
On the other hand, in the international hardware lock market, due to the rapid development of production technology and rising labor غير مجاز مي باشدts, developed countries in Europe and America will transfer common products to developing countries to produce only high value-added products, while China has a huge labor market. Naturally, it has become a major exporter of processing hardware in the hardware lock industry. In the foreseeable future, the export situation of lock products will only be better.
Large domestic demand for locks In the second half of 2009, China’s economy gradually emerged from the shadow of the financial crisis, and real estate and other industries took the lead in getting warmer. On the eve of New Year's Eve, house prices and trading volumes have experienced a period of almost crazy skyrocketing.

Elevator doors have two major types, manual and automatic. Manual doors are normally opened and closed manually by hand, and automatic doors are the standard type of doors found in modern days elevators, usually powered by a door operator.
Non-automatic/manual doors
These doors are normally opened or closed manually using hands, although some of them close automatically. Most older and small European elevators from the 1950's to 1970's are using manual hinged door (similar to normal room doors), while the inside has a manual sliding scissor gate or often there is no door at all. For manual doors, sometimes the door can be spring loaded so the gate can't be left open, or the gate can automatically close when you press the button, and partly/completely close when the elevator gets to a floor. The inside door can also be a tubular gate, which is a gate that in many cases folds around the side of the cab when it is open (often called a barred gate by elevator enthusiasts, though this is likely not the actual term), and which can be automatic or manual.
These type of door is still used today, normally for smaller wheelchair lifts or home elevators. Some older freight elevators may have a horizontal or vertical manual doors. In some Asian countries, one may find an old freight elevators with manual accordion or scissor gate. Some old elevators may have a semi-manual doors a configuration of manual door outside and an automatic door inside.
Automatic doors
Automatic doors are the standard type of doors found in modern days elevators which was introduced in 1887. Almost all the automatic doors are usually powered by a door operator installed on the elevator car. Those except manual door with automatic door opening/closing device and all the incline elevators with every independent door operator belongs with every single shaft doors and car doors.
