1) The stainless steel handle should be thick, otherwise it may bump: a good stainless steel handle uses a tube with a wall thickness of 1.2mm. At the same time, there are many classifications of stainless steel, and the price is very different. It is necessary to choose brand manufacturer AISI304 stainless steel as much as possible. The stainless steel handle of the thin tube is the same as the hand temperature soon after being grasped, while the thick tube is colder; the thick tube is knocked with fingers, the sound is crisp, and the thin tube will be a little boring. The handle has been used for many years with a tube with a wall thickness of 1.2mm. 2) Brass, zinc alloy and aluminum: Special attention should be paid to the fact that if the force is applied, the zinc alloy material should not be too thin, and it is recommended not to use it for functional accessories. The author has made statistics on the steel gate anti-theft doors in the community on a certain day. After three years of staying in, more than 60% of the handles are disconnected from the feet. The reason is that the zinc alloy fittings are too thin and the use of poor quality Zinc alloy.
