BL Series DT Leaf Chains

In order to meet the demand of the market, THC has developed DT leaf chains for highly corrosive environment and applications. DT leaf chains are galvanized and the surface is specially treated. All the chains parts are double plated before assembling. The chain surface coatings protect the chains against corrosion environments. The coating adheres well to the chains, and is very smooth and is difficult to scratch. Besides chromium is not used, so it is environmentally safe.

Features:
1) Resistant to Salt Water Spray: Better corrosion resistance than nickel-plated and zinc-plated. DT leaf chain stands up under salt-water (brine) spray tests for more than 500 hours.
2) Usable Outdoors: DT leaf chains are resistant to acid rain and other adverse weather conditions, which makes it extremely reliable for outdoor use.
3) Coating does not reduce chain strength: The temperature of the DT treatment process is low; so chain strength is unaffected. Accordingly, the tensile strength and allowable tension of DT leaf chains are the same as the chains without DT treatment.
3) Does not use chromium - environmentally friendly: Recently the regulation of harmful materials is being tightened worldwide and the use of chromium, as a material for surface treatment to prevent rusting, is gradually being restricted. Beijing THC recognizes the importance of these environmental concerns, and therefore our DT Chains have no harmful chromium, corresponding to the needs of the 21st Century.
4) Suggested Applications: Outdoor-use lifting mast, etc.
5) Specifications: operating temperature: -10 ~ +60 centigrade; chain color: silver
