        Where should safety locks be sold?

        Where should safety locks be sold?

        First, from the overall direction of development. Safety lock is relatively speaking is not so hot, but the past few years the rise of China's economic development, and around the real estate development accelerated. So I personally think that the next 20 years, the demand is still great.

        Second, from the product point of view, from the previous padlock, Ngau Tau lock, spherical lock, to the current more popular handle lock, and the future needs of the magnetic card lock, electronic lock, password lock, voice lock, etc. Slow out of the stage, now the handle lock personal think there are 10 - - 20 years or so of the market time, and now the high technological content of the magnetic card lock should be 10 years later will be popular to 2 --- 3 market, Even in rural areas.

        This is the development potential of safety locks.
