Stainless steel is a crucial material in the elevator industry, primarily due to its exceptional properties that make it suitable for various components and structures.
1. Stainless Steel for Vertical Elevators
Vertical elevator part | Grades | Thickness | Remark |
Car siding | 304/316L/430/439/443/201 | 1.0mm<= | |
Car door | 304/316L/430/439/443 | 1.0mm<= | |
Floor door (or hall door) | 304/316L/430/439/443 | 1.0mm<= | |
Control panel (or call panel) | 304/316L/430/439/443 | 2.0mm<= | |
Ridge | 304/430/439 | 0.8mm<= | Optional decoration |
Ceiling | 304 | 1.0mm<= | Optional decoration |
The main materials of vertical elevators are: 304, 316L, 430, 439, 443, 201
About thickness: 0.7, 0.8, 1.2, 1.5mm material thickness is mainly used for vertical elevator door plates and car wall plates. The thickness of 2.0 and 3.0mm is used for the elevator lifting button substrate.
2. Stainless Steel for Escalators
Escalator part | Grade | Thickness | Remark |
---|---|---|---|
Skirt Plate | 304/316L/430/439/443 | 1.5mm<= | |
The inner and outer cover | 304/316L/430/439 | 1.5mm<= | |
Arm guard | 304/316L/430/439 | 1.5mm<= | |
Exterior decorative board | 304/316L/430/439 | 1.0mm<= | |
Belly Plate | 304/316L/430/439 | 1.5mm<= | Optional decoration |
Step | 304/409 | 0.4mm-0.6mm | |
Floor cover | 304/316L/430/439 | 1.5mm<= | |
Floor cover base | 304/316L | 5.0mm<= | Hot-rolled structural parts |
Handrail rail | 304/316L | 1.5mm<= | |
Other decoration materials | 304/316L/430/439 | 1.5mm<= |
The main stainless steel materials for escalators are 304, 316L, 430, 439, 443. The material is basically the same as the vertical elevator.
3. Demand for Stainless Steel in the Elevator Industry
80% of elevators need stainless steel, and the industry’s average usage is 320~350kg per elevator. In 2012, the average consumption of stainless steel in the elevator industry was about 330kg per elevator, and the total consumption was about 175,000 tons.
