Hongxin steel pill, trustworthy! Welcome to the Hongxin official website

The 4th Fujian International Maritime Equipment Expo 2026 closed on October 19 at the Fuzhou Strait International Conference & Exhibition Center. Wuhan Hongxin Lixin Metal Products Co., Ltd. (Mali Steel Shot) followed the show closely: four days, eight hall forums running in parallel, and 34 Fortune Global 500 exhibitors. Fujian's local shipbuilding and repair cluster stood out.

Fuzhou now has a complete shipbuilding and repair chain: shipbuilding led by Fujian Shipbuilding Industry Group (including Mawei Shipbuilding and Southeast Shipbuilding), repair represented by Fujian Huadong Shipyard, Xingda Shipbuilding and Baozhong Marine, with Lianjiang, Mawei and Luoyuan developing in coordination.

Huadong Shipyard: nearly 1,000 tons of shot per year

Fujian Huadong Shipyard sits in Bili, Luoyuan, with a 300,000-ton dock. In 2024 it repaired 278 vessels, 95% foreign-flagged, with output of 1.342 billion RMB.

At an average of 3-5 tons of shot per vessel, annual shot consumption approaches 1,000 tons. These customers are highly sensitive to breakage — a few percentage points of abrasive cost on one vessel translates into hundreds of thousands of RMB.

Mali Steel Shot has a warehouse in Fujian with 48-hour delivery.

Mawei and Southeast: S330 for one, S280 for the other

Mawei Shipbuilding focuses on specialty vessels — it builds large open-top container ships — and uses S330 and S390 for large hull areas.

Southeast Shipbuilding builds new-energy hybrid tugs, where aluminum structures require fine S280 and S330 to avoid over-roughening the substrate.

Mali Steel Shot covers the full range, from S280 shot to G40 grit.

Smaller yards: small bags and local delivery

Hanhai Shipyard (Lianjiang Huangqi, 70,000-ton dock), Taiyuan Shipbuilding (a specialized SME), Jiexin Shipyard (Gaishan), and Guanhai Ship Repair (Lianjiang Guantou) use a few tons to a few dozen tons per month.

These customers suit small-bag packaging with local delivery. Mali Steel Shot offers ton bags, small bags, and bulk, shipped directly from its Fujian warehouse.
