Advantages of using Tokai Spring Industries’ products

Springs that are both rust-preventive and able to withstand large load.

Since the roller sluice gates used to open and close water gates are used in or near water areas, they are heavily affected by corrosion. That is why corrosion resistance is crucial for the springs used. Furthermore, in recent years, these springs have also become larger and heavier in load due to the requirements for bigger and resilient roller sluice gates.
At Tokai Spring, with the accumulated experience in designing and manufacturing the world’s largest coil springs and disc springs, and a proven track record of handling springs with strong corrosion resistance, we are confident to provide our clients heavy springs with excellent corrosion resistance features.
