Australian Standard Chain - Medium Link Chain is a versatile industrial chain engineered to meet rigorous Australian national standards, bridging the performance gap between short and long link variants. Constructed from high-quality mild steel (or marine-grade stainless steel for corrosive environments), it features a balanced link pitch design—longer than short link chains for easier attachment compatibility, yet shorter than long link options for enhanced load stability.
Manufacturing involves precision flash butt welding and optional heat treatment (for Grade 80 variants), with strict proof load testing to ensure compliance with safety benchmarks. Surface finishes include hot-dip galvanizing or advanced Galv360 coating, which diffuses zinc atoms into steel for superior corrosion resistance—critical for outdoor, coastal, or agricultural use. Each chain is embossed with batch numbers at 1m intervals for traceability, and key variants carry compliance markings to confirm adherence to Australian standards. Ideal for medium-duty applications, it balances strength, flexibility, and durability, making it a staple across logistics, marine, and industrial sectors.

Balanced Link Geometry: Medium pitch (between short/long link chains) enables compatibility with standard attachments (shackles, hooks) while maintaining load distribution efficiency—suitable for 0.8t-12t working loads depending on 3mm-24mm link diameters.
Enhanced Durability: Welded steel construction (with flash butt welded joints) and optional heat treatment (Grade 80 variants) deliver high tensile strength and resistance to shock loads, critical for dynamic industrial use.
Superior Corrosion Protection: Offers Galv360® (zinc diffusion coating) or hot-dip galvanizing; Galv360® provides 4x thinner, heat-resistant (up to 1200°F) protection vs. traditional galvanizing, ideal for marine/saltwater environments.
Full Compliance & Traceability: Embossed with batch numbers for traceability and meets Australian safety standards; marine-grade 316 stainless steel variants exceed DIN 764 specifications for corrosion resistance.
Versatile Sizing: Available in 3mm-24mm diameters (10mm-16mm most common for commercial use), with self-colour or galvanized finishes to match application needs.
Marine & Coastal Operations: Secures small-to-medium vessels (pleasure craft, fishing boats) to docks, and supports aquaculture mooring grids—316 stainless steel or Galv360® coated variants resist saltwater corrosion.
Agricultural Use: Ties down farm machinery (harvesters, irrigation systems) during transport and secures hay bales/stock feed; galvanized finishes withstand soil moisture and fertilizer exposure.
Industrial Lifting (Medium-Duty): Lifts lightweight construction materials (wooden beams, metal piping) and positions factory equipment; Grade 80 heat-treated variants handle trawling gear in commercial fishing.
Logistics & Warehousing: Secures palletized cargo (electronics, consumer goods) on trucks/trailers; balanced link design prevents slippage without compromising attachment speed.
Infrastructure Maintenance: Supports temporary safety barriers and secures tools during bridge/road repairs; durable welds withstand vibration and environmental stress.
Q1: What’s the difference between Medium Link Chain and Short/Long Link variants?
Medium Link offers a balanced pitch: longer than short link (for easier shackle compatibility) and shorter than long link (for better load stability). Short link suits <0.8t loads/tight spaces; long link for >12t heavy lifting. Medium link (0.8t-12t) is ideal for applications needing both flexibility and strength.
Q3: Which finish is best for saltwater environments?
Choose either 316 stainless steel (DIN 764 compliant) or Galv360® coated steel. Galv360® uses zinc diffusion to resist corrosion 4x better than traditional galvanizing, while 316 stainless steel offers superior chemical resistance—both outperform standard hot-dip galvanizing in saltwater.
Q3: How often should I inspect the chain, and what defects matter most?
Inspect before each use and monthly for frequent operations. Key defects: cracked link plates/rollers, rotated pins, >10% link elongation, or worn plate edges. If found, replace immediately—never use damaged chains for lifting/securing.
Q3: Can I mix Medium Link Chain with attachments from other brands?
Yes, if attachments (hooks, shackles) match the chain’s diameter, load capacity, and meet Australian standards. For example, a 10mm medium link chain requires a 10mm shackle rated for ≥2t. Avoid undersized attachments—they can jam or fail under load.
Q3: What’s the proof load testing requirement for this chain?
All Australian Standard Medium Link Chains undergo proof load testing (typically 2x the working load limit) during manufacturing. Batch numbers (embossed every 1m) allow tracing test records—request a copy from your supplier to confirm compliance.
