Import As2321 Short Link Chain Grade — Buy in wholesale FOB from Supplier in China

Dawson Group Ltd. manufactures short link alloy steel chain conforming to AS 2321 for lifting applications, with Grade 100 offering a 25 percent strength advantage over Grade 80 for equivalent nominal sizes. Each link is embossed with G100 and a traceability code, quenched and tempered from alloy steel billet, and proof loaded to verify integrity before despatch. The 4-to-1 design factor mandated by AS 2321 governs working load limit calculations, ensuring the chain operates within safe margins under dynamic lifting conditions common in construction, mining and marine rigging sectors.

The alloy steel composition typically includes chromium, nickel and molybdenum additions to achieve through-hardening and toughness after quenching and tempering. Link dimensions follow the short link pattern, with inside length approximately 3.5 times the material diameter and inside width approximately 1.25 times the material diameter, though exact proportions vary by manufacturer specification. Blue or black electrophoresis coating provides base corrosion protection; buyers should confirm coating thickness and salt spray resistance with Dawson for marine or corrosive environments where additional galvanising or plastic jacketing may be warranted.

Grade 100 chain enables downsizing of sling assemblies, reducing headroom requirements and handling weight compared with Grade 80 equivalents for the same working load limit. Typical buyers include crane hire companies, offshore rigging contractors, and heavy engineering fabricators who require certified lifting media with full material traceability. The Dawson Group facility in Qingdao, Shandong province, positions the supplier near major northern Chinese steel producers and container ports, though buyers must negotiate minimum order quantities, lead times and Incoterms directly as these are not specified in the listing data.

Dawson Group Ltd. maintains its headquarters at 22nd Floor, Yuheng Building, 170 Xuzhou North Road, Qingdao, Shandong province, 266700, China. The company holds a 'harbor' trust tier classification on the marketplace, with zero recorded response rate and no average response hour data available. This absence of platform-mediated communication history means buyers should establish direct contact through multiple channels and allow additional time for initial quotation and technical clarification requests.

The supplier profile does not disclose manufacturing facility location, production capacity, employee count, year of establishment, or specific quality management certifications such as ISO 9001 or ISO 14001. No end-user references, third-party inspection body accreditations, or export market registrations are listed. Buyers are strongly advised to conduct supplier due diligence including factory assessment, review of welding and heat treatment process controls, and verification of AS 2321 testing protocols before committing to safety-critical lifting equipment procurement.
