Global Solutions

A diversified corporate group spanning multiple industries, including bulk metal raw materials, precision machinery and metal products, new energy, and marine and shipbuilding engineering.

Bulk raw materials

Our bulk metal raw materials include nickel, nickel‑iron, tungsten‑iron, boron‑iron, ferrosilicon, ferromanganese, ferromolybdenum, ferrovanadium, ferrochrome, and metallic silicon, among others. We primarily supply major steelmakers, battery manufacturers, automotive and component producers, as well as photovoltaic and wear‑resistant material manufacturers, both domestically and internationally. Leveraging our robust supply chain network and deep industry expertise, we consistently deliver stable, efficient, and competitively priced raw material solutions that add value for our customers.

Marine Engineering

The company primarily engages in offshore wind‑farm pile foundation construction, wind‑farm operations and maintenance, bridge construction, underwater anti‑corrosion engineering, and marine oilfield engineering. Its core services include marine engineering technical consulting, wind‑farm operation and maintenance along with related technical advisory, as well as bridge construction, wind‑farm foundation installation, underwater anti‑corrosion work, and marine engineering projects.

Metal products

Our company specializes in the sale of a wide range of products, including work rolls, dies, ring‑rolling rolls, hydraulic machinery components, mining equipment parts, marine‑engineering components, alloy cast‑steel rolls, graphite steel rolls, and fan shafts. We offer consistently high product quality and exceptional dimensional accuracy. With an extensive product portfolio, we provide custom‑made, non‑standard solutions tailored to customers’ drawings, ensuring efficient delivery. We also deliver one‑stop roll procurement and supporting services to clients in the metallurgical and steel‑rolling industries.

New Energy Vehicles and Materials

We have deeply cultivated the new‑energy vehicle supply chain, offering integrated solutions for core component materials, semiconductor devices, and charging equipment. Our key products include high‑thermal‑conductivity silicon nitride ceramic substrates that efficiently dissipate heat from automotive‑grade SiC power modules, as well as a broad range of automotive‑grade semiconductor power components covering electronic control systems and on‑board power supplies. We also supply residential and commercial DC fast‑charging stations along with their complementary accessories. Backed by a stable supply chain, we provide automakers, charging operators, and electronics manufacturers with one‑stop procurement solutions, rigorously ensuring product quality and compatibility with high‑voltage fast‑charging and in‑vehicle electronic control applications. We are committed to delivering highly reliable supporting components to the new‑energy industry.

Cemented Carbide Tools and Materials

Our company specializes in the sale of a wide range of cemented carbide cutting tools and tungsten carbide powders. Our tungsten carbide powders meet stringent purity standards and feature uniform particle sizes. Cutting inserts, manufactured via powder metallurgy—comprising tungsten carbide combined with cobalt—are exceptionally hard, wear‑resistant, and heat‑resistant, making them the mainstream choice for modern machining applications. We offer a comprehensive selection of cutting inserts and can also provide custom, non‑standard solutions tailored to specific customer requirements, ensuring optimal performance across all machining scenarios. Our products are widely used in mechanical manufacturing sectors such as automotive, shipbuilding, aerospace, and equipment production.
