Good door with good lock, what kind of door with what kind of lock, but do you know how to choose a good lock? Now in the market, the variety of hardware lock is complex, the style is similar, so many ordinary consumers are very headache. So how to choose a good door hardware lock, lock expert Fu Shi Li to give you advice, grasp the following four see is very important.
1、 Look at the lock information
The locks on the market are divided into stainless steel, copper, zinc alloy, aluminum alloy and iron, etc. Each of these materials has its own advantages and disadvantages. Stainless steel has high strength, strong corrosion resistance and no discoloration, which is the best material for lock making. However, the casting function is not good, and the style and color of stainless steel door lock are relatively single. Copper material mechanical function is superior, generally used to make European high-grade door lock, price and level are relatively high. Zinc alloy has strong wear resistance, corrosion resistance and other functions, and relatively simple casting, can plan many patterns and stripes, at present, many of the hot-selling locks on the market are made of zinc alloy. However, due to the different proportion and material of zinc alloy and the different casting process of planning process, the price difference is very big. Aluminum alloy and iron are less used. Aluminum alloy is mainly space aluminum. This kind of door lock planning is generally relatively simple, and there is no speckle planning. Iron door locks are less and less, which is basically attributed to the low-end door locks. There are many kinds of locks. Locks of different materials and levels are available. The main reason is to choose big brands according to their own budget and style. The brand and quality are guaranteed.
2、 Look at the appearance of the lock
The surface treatment of locks can be roughly divided into electroplating, spraying and coloring. Through surface treatment, locks form a layer of dense protective film on the surface of products, which has the effect of anti-corrosion and anti rust, making the lock more beautiful and practical. The dense protective film is also a standard to measure the quality of locks. For locks with good quality, electroplating treatment is often used. The coating is fine and smooth, even and moderate, and the color is gorgeous, without bubbles, rust and oxidation traces. For example, TINO hardware products are all through the layer plating process and polishing process, 48 hours of moderate salt spray test or 200 hours of low-level salt spray test, to ensure that the appearance of the products will not be mottled and oxidized rust due to the use and disappearance of time.
