SURFACE-TREATED CHAINS (N), (BC), and (DG)
These surface-treated chains have attractive appearance and increased corrosion resistance. Select the optimum type from the surface-treatedchains to suit your application.

Rustop（N）

All parts are plated with special nickel.

Attractive nickel-plated appearance and corrosion resistance
Maximum allowable load: About 15% lower than that of standard steel chain (see next page)
Operating range: -10℃ to +60℃
Usable instead of most steel chains and chains with attachment
When ordering, please put a suffix“N”to Chain No.

Special mechanical surface-treatment on all parts. Matte darkgray finish. Compliant to RoHS Directive

BC Coat（BC）

Usable even when subject to seawater
Maximum allowable load is the same as that of standard steel chain (see next page)
Protective film has higher peeling resistance than that of DC coat chain.
Ordinary operating temperature range of -10℃ to +150℃
Usable instead of most steel chains and chains with attachments
When ordering, please put a suffix “BC"DG COAT（DG）

to Chain No.

Special coat and top coat on all parts. Compliant to RoHS
Directive

Usable even when subject to seawater
Maximum allowable load is the same as that of standard steel chain (see next page)
Operating range: -10℃ to +60℃
Usable instead of most steel chains and chains with attachments
When ordering, please put a suffix “DG"

to Chain No.

RoHS Directive refers to the European Union's Directive on the Restriction of use certain Hazardous Substances in electrical and electronic equipment.

Safety Precautions: Do not use surface-treated chain if chain directly contacts food or abrasion particles are mixed
into food.

NOTES: - Dimensions of surface-treated chains are the same as those of standard steel chains.
- Connecting links of BC coat chains are split pin type.
- Surface-treated chain can be used in place of most standard steel chains and chains with attachments.
