Our daily life is inseparable from taking the elevator. So, do you know why elevators use stainless steel?
It is understood that at the beginning, real mirrors were used in the elevator, and the advantage is that the space is large because when people see “self” in the mirror, they will visually feel that the distance between themselves and the “self” in the mirror will lengthen. Because of this visual effect, the small space in the elevator does not appear to be so “cramped”. The benefits of using mirrors are obvious, but mirrors are fragile and expensive to maintain. As a result, designers began to switch to mirror-finished stainless steel, which quickly became popular.
Advantages of stainless steel
Stainless steel is strong, wear-resistant, never discolored, easy to clean, beautiful in appearance and has a special metallic luster. At the same time, it is also an environmentally friendly decorative material, free of organic substances such as methanol, no radiation, safe and fireproof.
Modern elevators are mainly composed of traction machines (winch), guide rails, counterweight devices, safety devices (such as speed limiters, safety gears and buffers, etc.), signal control systems, car and hall doors, etc. Elevators have specific requirements for the strength and corrosion resistance of steel. At the same time, as an important part of modern buildings, the appearance, fire protection and environmental protection of elevators are all important considerations. Stainless steel has the advantages of excellent strength, corrosion resistance, beautiful appearance and environmental protection, and has become one of the important materials for making elevators.
Where is stainless steel mainly used for elevators?
Stainless steel is mainly used in elevator car decoration, ceiling, car door and hall door, door cover, floor display, control panel and handrail, etc. Decorative package.
What grade of stainless steel is mainly used for elevators
The grades of stainless steel for elevators are mainly concentrated in 304, 439, 443 and 316L. Among them, the amount of 304 stainless steel is the largest. The excellent corrosion resistance and mechanical properties of 304 have become the first choice for elevator companies. 316 stainless steel is mainly used in seaside, high corrosion occasions and heavy-duty escalators. 430 stainless steel is also widely used in the elevator industry. It is relatively inexpensive and is used in general occasions and steps.
