Import Admiralty Stock Anchor For Ship — Buy in wholesale FOB from Supplier in China

The Admiralty Stock Anchor from Qingdao Real Tiger Marine Equipment is a conventional holding anchor manufactured by casting, with nominal weights ranging from 50 kg to 10,000 kg. This anchor type features a central shank, two flukes pivoted at the crown on a stock that orients the flukes to dig into the seabed, and a stock crossbar that ensures proper setting orientation. Cast construction from specified marine-grade steel allows complex fluke geometry optimised for penetration in sand, mud, or clay bottoms. The weight range covers small coastal vessels through large commercial ships, with holding power proportional to anchor mass and the fluke-to-shank angle design. Classification society certification from CCS, ABS, BV, NK, KR, GL-DNV, LR, RINA, or RMRS is available, confirming design compliance with respective rules for anchor construction and testing.

Manufacturing employs sand casting or precision investment casting depending on anchor size, followed by heat treatment to achieve specified mechanical properties and surface cleaning to SA 2.5 for coating adhesion. Typical materials include cast carbon steel or cast steel alloy to GB/T 552, ASTM A29, or equivalent standards, with specified minimum tensile strength of 400-490 MPa depending on classification society requirements. The stock is typically forged or cast separately and secured with a locking pin or cotter arrangement. Fluke angles follow Admiralty pattern geometry, typically 30-35 degrees to the shank axis, optimised for reliable setting without excessive dragging. Shank and fluke thicknesses are proportioned to resist bending loads during deployment and retrieval, with typical safety factors of 4 to 6 against ultimate strength for static holding loads. For anchors above 1,000 kg, individual casting identification marks and test documentation are mandatory under most classification rules.

These anchors serve merchant vessels, fishing fleets, offshore support vessels, and workboats requiring reliable primary or secondary anchoring systems. Buyers include shipyards constructing newbuild vessels, ship owners replacing worn anchors during dry-docking, and marine equipment distributors serving regional fleets. The Admiralty pattern remains specified for many traditional hull forms where its predictable setting behaviour outweighs the higher holding power-to-weight ratio of modern designs such as stockless or Bruce anchors. OEM availability allows customisation of shank length, fluke profile, or crown fitting geometry to suit specific vessel hawse pipe arrangements or anchor handling equipment. Buyers should confirm the exact weight required for their vessel's equipment number, the classification society certificate needed for regulatory compliance, and any special surface treatment or marking requirements directly with Qingdao Real Tiger Marine Equipment.

Qingdao Real Tiger Marine Equipment Co., Ltd. is located at Ximansion, Yanqing Road, Jimo, Qingdao, Shandong Province, 266200, China, a coastal location with established marine equipment manufacturing infrastructure. The company carries a 'harbor' trust tier and shows a 0.00% response rate with zero average response hours, indicating no response history is recorded. Buyers should test communication channels directly before relying on this supplier for time-critical orders. The company positions itself as a marine equipment supplier with a product range extending beyond anchors to anchor chain, mooring rope, wire rope, and deck equipment including bollards and chain stoppers.

The supplier states possession of CCS, DNV, GL, ABS, BV, LR, NK, KR, and RINA classification society certificates, plus ISO9001:2008 quality system certification. No specific scope of certification, certificate numbers, or validity dates are provided in the available data, so buyers should request current certificate copies with scope statements. The company does not disclose founding year, annual revenue, employee count, or named clients, so production capacity and market position must be assessed through direct enquiry and factory audit. The Jimo district location places the company within Qingdao's broader marine industry cluster, which offers logistical advantages for port delivery but does not independently guarantee manufacturing capability.
