Brand and modeling
When we choose a door lock, we first look at the brand and shape, and the brand creates credibility and quality.
Material selection
Lock materials on the market are divided into stainless steel, copper and zinc alloy. Stainless steel has high strength, corrosion resistance and no discoloration, which makes it brighter and brighter as it is used. Copper is one of the most common and widely used lock materials, with superior mechanical properties, but relatively high price, strong wear resistance, strong corrosion resistance, smooth surface, good compactness, no pores and easy molding, which is used for mid-range locks.
surface treatment
The surface of the door lock is electroplated or sprayed to form a protective film on the surface, which has the function of corrosion prevention and rust prevention, making the product look more beautiful and durable. At the same time, we should also measure the product quality standards. The locks with good quality should be electroplated, with fine and smooth coating, bright color and no rust.
Handle and drape
Feel the quality of the lock by hand, and weigh the lock by hand. The lock feels heavy, indicating that the lock core is made of thick, wear-resistant and relatively high materials. The material is thin and easy to be damaged, and the lock body cannot be exposed, which is easy to hurt people. Pay special attention to the end of the lock handle. The lock has the advantages of flexible opening, high sensitivity and long service life.
