Steel lifting chain Grade 80

alloyheavy-dutycorrosion-resistant

Product Overview
Grade 80 lifting chain (load chain) is manufactured from alloy steel using advanced production lines to deliver high tensile strength for industrial lifting applications. Produced to ISO3077, EN818 and AS2321 standards, the G80 chain meets a 4:1 safety factor and a 2.5× tested loading capacity. Available surface finishes include self-coloured, black oxide, electro-galvanized, hot-dip galvanized, powder coating and painting to suit humid, acidic or alkaline environments.

Applications

• Chain blocks, lever hoists and electric hoists
• Cranes, winches, lifting slings and industrial lifting operations
• Precision calibrated load chains and heavy-duty lifting chains

Key Features / Details

• Material: alloy steel (examples: 20Mn2, 20Mnv and similar)
• Available grades: Grade 80 (G80), Grade 70 (G70), Grade 60 (G60)
• Safety: 4:1 safety factor; tested load factor 2.5×
• Surface treatments: natural/self-coloured, black oxide, shot blast, electro-galvanized, powder coated, hot galvanized, painted
• Typical uses: load chain, lifting chain, welded lashing chain, transfer chain
