Australian Standard Chain-Grade L Chain

Australian Standard Chain-Grade L Chain

Australian Standard Chain - Grade L Chain is a specialized low-tensile steel chain fully compliant with AS 2321 (Australian Standard for Link Chains) and AS 1418.1 (Crane Mechanisms), primarily designed for light-to-medium duty applications. Constructed from high-quality low-carbon steel (with stainless steel options for corrosion-prone environments), it features a calibrated short-link configuration that ensures compatibility with most Australian marine windlasses and standard rigging hardware.

Manufactured via precision welding, Grade L Chain undergoes strict quality checks, including proof load testing with a minimum design factor of 5:1 (extendable to 4:1 for specific mooring needs). Surface finishes include electro-galvanizing, hot-dip galvanizing, or bare metal, with galvanized variants offering enhanced rust resistance for outdoor and marine use. Each chain is marked with "HDJ-L" or equivalent identifiers for traceability and comes with test certificates upon request. Unlike high-grade alloy chains, it is not rated for overhead lifting but excels in static load-securing and marine anchoring, making it a cost-effective choice for industries requiring reliable, standards-aligned low-tensile solutions.

Product Details

Australian Standard Chain-Grade L Chain Features：

Short-Link Design: Calibrated short links ensure proper fit with Australian windlasses (critical for marine anchoring) and easy attachment of standard shackles/hooks.
Corrosion-Resistant Finishes: Electro-galvanized/hot-dip galvanized coatings protect against saltwater, moisture, and outdoor elements; stainless steel variants available for extreme corrosion environments.
Controlled Design Factor: Built with a 5:1 design factor (safety ratio) for general use, adjustable to 4:1 for specific mooring applications, ensuring load stability without overengineering.
Non-Lifting Rating: Explicitly not approved for overhead lifting (per AS 1418.1), preventing misuse in high-risk heavy-lifting scenarios.

Australian Standard Chain-Long Link Chain Typical Applications:

Marine Anchoring & Mooring: Ideal for boat anchor chains (pleasure craft, small commercial vessels) and dock mooring—short-link design fits Australian windlasses, while galvanized finishes resist saltwater corrosion .
Agricultural Use: Used as tractor tow chains, hay bale securing chains, and farm equipment tie-downs; low-carbon steel withstands soil moisture and minor impacts .
Light Construction: Secures temporary structures (safety barriers, small scaffolding) and lifts lightweight materials (wooden planks, small metal parts) via ground-based rigging (not overhead) .
Transport & Logistics: Functions as trailer safety chains and light cargo binders (e.g., securing small machinery parts on utility trailers); compatible with standard load binders .
Recreational & Industrial Support: Used in log cabin construction (rafter support), playground equipment anchoring, and light industrial storage (securing non-heavy inventory) .

FAQ

Q1: Is Grade L Chain approved for overhead lifting?

No. Grade L Chain is explicitly not rated for overhead lifting (per AS 1418.1). It lacks the tensile strength and stiffness required for vertical load-bearing—use Grade 80/100 alloy chains instead for overhead applications .
Q3: What’s the working load limit (WLL) of Grade L Chain, and how is it determined?

WLL typically ranges from 0.3t to 3t, depending on link diameter (6mm-16mm common). It is calculated based on a 5:1 design factor (load capacity vs. breaking strength) for general use; this can be adjusted to 4:1 for specific mooring needs (confirm with supplier) .
Q3: Which finish is best for saltwater marine use?

Hot-dip galvanized Grade L Chain is recommended for saltwater—it provides thicker zinc coating than electro-galvanizing, offering superior resistance to salt corrosion. For extreme marine environments, opt for stainless steel variants .
Q3: Will Grade L Chain fit my Australian windlass?

Yes. Its calibrated short-link design is specifically engineered to match most Australian windlass specifications, ensuring smooth winding/unwinding during anchoring .
Q3: How do I maintain Grade L Chain to extend its life?

For galvanized variants: Rinse with fresh water after saltwater use, dry thoroughly, and apply a light marine lubricant every 2-3 months. For bare metal: Inspect for rust monthly, remove surface rust with a wire brush, and apply anti-rust paint annually .
Q3: What’s the difference between Grade L and Grade 70 Chain?

Grade L is low-carbon steel (AS 2321) for light-medium static loads (anchoring, tying down). Grade 70 is heat-treated alloy steel (ASTM standard) with 20% higher WLL, designed for transport/cargo securing—but neither is approved for overhead lifting .
