Marine & Shipbuilding

Marine Hardware Supply for Global Shipping

In an industry where a single failed fastener can disable a vessel, delay a voyage, or compromise crew safety, only the most reliable hardware earns its place on board. We are a trusted supplier of marine hardware and rigging products to leading shipping companies, shipyards, and offshore operators worldwide. Our comprehensive product portfolio covers every critical connection point across the entire vessel lifecycle — from steel hull erection and outfitting during newbuilding, to daily operations, mooring, cargo securing, and dry-docking maintenance. Whatever the challenge at sea, we supply the strength to meet it.

Load-rated from 0.5T to 850T, forged alloy steel, hot-dip galvanized, each with traceable material certificates and proof-load testing. Used for mooring connections, towing, anchor chain attachment, crane rigging, and heavy lifts.

· Turnbuckles & Rigging Screws — HG-226 eye-to-eye, HG-227 jaw-to-eye, jaw-to-jaw, and DIN 1480 open-body turnbuckles, sizes M6 through M64, WLL up to 22T. For mooring line tensioning, stay rigging, railing adjustment, and container lashing — delivering fine-tuned load control where every millimeter of tension matters.

Mooring & Anchoring Systems — Holding Vessels Secure in Every Port

· Wire Rope — 6×19+FC, 6×37+FC, 6×36WS+IWRC, and 8×19S galvanized and stainless steel wire rope, diameters 6mm through 64mm. For mooring lines, towing hawsers, crane pendants, and lifeboat falls.

· Wire Rope Slings — Hand-spliced eye-and-eye slings, Flemish-eye mechanically-spliced slings, pressed-ferrule slings, and endless grommets. Each supplied with full break-load test certification — for crane operations, heavy maintenance lifts, and provision handling.

· Anchor Chain — Stud-link (AM1/AM2/AM3) and studless anchor chain in Grade U1/U2/U3, with matching end shackles, swivel pieces, and anchor shackles — the primary holding power for every vessel at anchor.

· Synthetic Fiber Ropes — Polyamide (PA), polyester (PES), and ultra-high-molecular-weight polyethylene (UHMWPE) mooring lines and tails — lightweight, high-strength, and flexible for modern vessel mooring systems.

· Mooring Fittings — Panama chocks, closed fairleads, bollards (single/double bitt), roller fairleads, and pipe-type hawse pipes — cast and forged steel, hot-dip galvanized, guiding and securing mooring lines on deck.

· Chain Stoppers & Releasers — Screw-type and bar-type chain stoppers, quick-release wildcat releasers — securing anchor chain under load and enabling emergency release.

Container Lashing Equipment — Securing Cargo Across the Oceans

· Twistlocks — Semi-automatic and fully automatic twistlocks for vertical container-to-container and container-to-deck connection.
