Bulb Flat Steel is mainly used in shipbuilding, marine engineering, steel structure engineering, and bridge engineering. In recent years, with the rapid development of the shipbuilding industry, the demand for ball-flat steel is very strong. Most ships choose ball-flat steel for structural design.

Marine angle steel (marine unequal angle steel, marine equal angle steel) is a new type of profile produced to meet the needs of large ship-building. In addition to being used for large ships, it can also be used for marine engineering structures and high-demand building engineering structures. Marine equal and unequal angle steels are mainly used to make frame structures.

Our welding materials products consist of three major series: solid welding wires, flux-cored welding wires, and welding electrodes, with over 200 varieties in total. In addition to their conventional applications, our products are also evolving towards specialized welding materials for high-strength steel, heat-resistant steel, stainless steel, and non-ferrous metals. These welding materials are widely used in various industries, including steel structure construction, shipbuilding, pressure vessels, oil pipelines, rail transit, marine engineering, and nuclear power.

Inverted angles are also known as "L-shaped section steel" " unequal-leg and unequal-thickness angle steel". It is a new type of profiled bar produced to meet the needs of large-scale shipbuilding. Apart from being used in the construction of large ships, inverted angles can also be applied in ocean engineering structures and construction engineering structures with high requirements. Marine equal-leg and unequal-leg angle steel is mainly used for the fabrication of frame structures.
