Towing chain Grade 30

steelzinc-platedcorrosion-resistant

Overview
Grade 30 proof coil chain, electronically welded, supplied on a half drum with electro-galvanized finish (hot-dip galvanizing referenced for enhanced corrosion protection). Intended as a general utility chain meeting NACM and ASTM classifications. Not for overhead lifting; always respect the published Working Load Limit (WLL).

Applications

• General utility uses: farm equipment, log chain, tow chain, switch chain.
• Suitable for outdoor and agricultural environments when corrosion protection is required.
• Not designed or certified for overhead lifting or personnel lifting applications.

Caution

• Do not use for overhead lifting under any circumstances.
• DO NOT EXCEED THE PUBLISHED WORKING LOAD LIMIT (WLL).
• Inspect chain before each use; remove from service if links are deformed, cracked, severely corroded or otherwise damaged.
• Follow applicable regulations and manufacturer instructions for storage, installation and use.

Technical parameters

• Grade: 30 (NACM/ASTM classification)
• Material: Low carbon steel
• Manufacture: Electronically welded proof coil
