We are constantly asked at Elevate “why can’t I use any type of chain for lifting?” and “How to identify chain grade”? The simple answer is that there are many variations designed for different applications.
Chain is generally described using its grade. At Elevate we stock all grades of chain from reputable manufacturers.
Common manufacturers are Thiele, KITO PWB, Yoke, Pewag, Gunnebo and RUD.
The list below shows the most common chains supplied not only to industry but in some cases general household use. All chains except for hardware are generally manufactured to Australian Standards. At Elevate we only supply chain that conforms to the standard applicable to the grade.
Chains are available in self colour, galvanised, Zinc or painted. Most common colours are yellow, Blue, Orange and Green. Most manufacturers have a colour that identifies the chain as theirs.
Commercial Chain – Commercial chain is a basic economical chain manufactured for general purpose applications. Available in galvanised or self-colour options. It is not to be used for lifting or lashing.
Proof Coil – Proof Coil is a tested, not heat treated, mild steel chain. Manufactured in sizes from 6mm to 24mm. It is manufactured from low grade carbon steel and is proof tested to at least twice the maximum load recommended for use. Available in galvanised or self-colour options. It is not to be used for lifting or lashing.
Stainless Steel – Stainless Steel chain is manufactured from Type 316 or 304 stainless which is highly resistant to corrosion in acid, alkaline, marine and salt-water environments. Typical applications for stainless steel chain include pump chains, netting chains and trawl chains. Available in short and regular link. Also available in lifting grade, specifically Grade 60, this is available on request from Elevate.
Grade 70 – manufactured from high tensile steel. Also know as tie down or transport. Chains and fittings are a vital component of safe transport of goods. Chain suitability is determined by its size, strength, hardness and elongation. Elevate supplies high quality chain and assemblies that comply with AS 4344. Identified by the Australian standard along with the lashing capacity stamped on the links. Grade 70 fittings are available suitable for this grade of chain only.
Grade 80 – is manufactured from alloy steel and is hardened and tempered. It has a load bearing capacity more than three times of mild steel chain. This chain complies with AS 2321 for Lifting Chains. It is the most common high tensile chain used in chain assemblies and is compatible with an extensive range of lifting fittings. Identified by markings on the link such as T, 8, 80 or 800. Grade 80 is a harder chain than grade 70 and does not yield like lower grades.
Grade 100 – is manufactured from alloy steel and is hardened and tempered like Grade 80. It offers 25% greater working load limits than Grade 80. This chain complies with AS 2321 for Lifting Chains. It is compatible with a limited range of lifting fittings. Identified by markings on the link such as 10, 100.
Grade 120 – the new player on the block. Still trailing well behind grade 80 and grade 100, Grade 120 chain is designed for the biggest overhead lifting applications. Grade 120 Chain is a premium chain manufactured from high strength alloy steel. Grade 120 Chain has a 50 percent increase in working load limit as compared to a similar size chain in Grade 80. The Significant weight advantage grade 120 offer makes handling, storing and transporting considerably more safely and economical.
