Australian Standard Chain - Grade 70 Chain is a high-performance industrial chain compliant with Australian national standards, engineered for heavy-duty load-bearing and securing tasks. Crafted from heat-treated alloy steel, it delivers exceptional tensile strength and impact resistance, outperforming lower-grade chains in demanding environments. Its design prioritizes safety and durability, with strict quality control during production to meet Australia’s rigorous industrial safety benchmarks.
The chain typically features a corrosion-resistant finish—such as hot-dip galvanizing or zinc plating—to withstand moisture, chemicals, and outdoor exposure, extending its service life. With a clear working load limit (WLL) marking, it ensures easy compliance with operational safety protocols. Widely adopted across key industries, it balances reliability and versatility, making it a go-to solution for applications requiring consistent performance under high stress, from cargo securing to heavy lifting.

Superior Strength: Heat-treated alloy steel construction provides high tensile strength and load-bearing capacity, supporting heavy loads without deformation or breakage.
Corrosion Resistance: Galvanized or zinc-plated surface treatment protects against rust, moisture, and chemical erosion, suitable for indoor and outdoor use.
Safety Compliance: Clearly marked with “Grade 70” and WLL values, aligning with Australian safety standards to prevent overloading risks.
Durability: Tough alloy steel material resists wear, impact, and fatigue, ensuring long-term use even in frequent, high-stress operations.
Versatility: Compatible with standard attachments (hooks, shackles, links), adapting to diverse lifting and securing needs.
Transportation: Securing heavy cargo (e.g., machinery, construction materials) on trucks, trailers, and shipping vessels to prevent shifting during transit.
Construction: Lifting and positioning steel beams, concrete blocks, and heavy equipment at construction sites via cranes or hoists.
Logistics & Warehousing: Handling pallets, containers, and large inventory with forklifts or overhead cranes for efficient material movement.
Mining: Pulling and lifting mining equipment (e.g., drills, ore buckets) in harsh underground or open-pit mining environments.
Agriculture: Securing farm machinery (e.g., tractors, harvesters) during transport or lifting hay bales and irrigation equipment.
Q1: What is the maximum working load limit (WLL) of Grade 70 Chain, and how do I confirm it?
The WLL varies by chain size (e.g., 6mm to 16mm links) but typically ranges from 0.5t to 8t. It is clearly engraved on each chain link—look for markings like “70” and the WLL value (e.g., “70 2t”).
Q3: Can this chain be used outdoors long-term, and how to maintain its corrosion resistance?
Yes, thanks to its galvanized/zinc-plated finish. To maintain protection, clean off dirt/chemicals regularly with mild detergent, dry thoroughly, and apply a light industrial lubricant annually to prevent finish wear.
Q3: Is Grade 70 Chain compatible with all types of hooks or shackles?
It works with standard industrial hooks/shackles (e.g., clevis hooks, eye shackles) that match the chain’s size and WLL. Avoid using undersized or low-grade attachments, as they can compromise safety.
Q3: How often should I inspect the chain for damage, and what signs should I look for?
Inspect before each use and monthly for frequent operations. Watch for stretched links, cracked/worn link plates, rust pitting, or faded WLL markings—replace the chain if any of these issues are found.
Q3: Can Grade 70 Chain be repaired if it gets damaged, or must it be replaced?
Repairs (e.g., welding broken links) are not recommended, as they weaken the chain’s structural integrity. Damaged chains should be replaced immediately to avoid safety hazards.
