How to distinguish the advantages and disadvantages of stainless steel handle materials
1) Stainless steel handles should be thick, otherwise they may be dented: good stainless steel handles use pipes with a wall thickness of 1.2mm. There are also many classifications of stainless steel, and the prices vary greatly. It is advisable to choose brand manufacturer AISI304 grade stainless steel as much as possible.The stainless steel handle of the thin tube is quickly held at the same temperature as the hand, while the thick tube is cooler; Tapping the thick tube with your fingers produces a clear and crisp sound, while the thin tube can be a bit dull. The handle has been using pipes with a wall thickness of 1.2mm for many years.2) Brass, zinc alloy, and aluminum: It is particularly important to note that if subjected to force, zinc alloy materials should not be too thin and should not be used for functional accessories. The author has conducted statistics on the steel gate anti-theft door in a certain residential area on a certain day. After three years of occupancy, more than 60% of the handles were disconnected from the foot seat, because the zinc alloy accessories were too thin and inferior zinc alloy was used. It is difficult to distinguish the material of all materials after surface treatment, so customers must ask clearly.3) Natural stone, natural wood, plastic: There are many materials used to make stainless steel handles, and each material has its own advantages and disadvantages, which will not be elaborated here.Article source: Stainless steel handle manufacturer http://m.xagudao.com
