Flat-bulb steel is mainly applied to ship, marine, steel structure and bridge engineering. With rapid development of ship manufacturing industry in recent years, demand for flat-bulb steel is flourishing. Most ships select flat-bulb steel in structural design.

Steel bar for pre-stressed concrete (PC steel bar for short) is pre-stressed concrete steel with very high technical content, which is developed by Japan Neturen Co., Ltd. in the 1960s. It features high strength toughness, low looseness, strong concrete bond stress, good weldability and upset forging and material saving. It is widely applied to high strength pre-stressed concrete centrifugal pipe pile, electric pole, overpass pier and other pre-stressed concrete components, and has very wide market in the world, in Southeast Asian regions in particular.

Grinding steel ball for grinding mill (grinding ball for shorter) is a kind of pulverizing media in ball mill to crush the materials in the mill. After in-depth discussion and analysis, combining with actual working condition of ball mill, grinding ball (specially for ball mill) with higher volume hardness and better wearability is developed through research and promotion of steel ball material and supporting heat treatment process. It improves grinding efficiency effectively without lowering grinding effect, which is beneficial for energy saving and consumption reduction of mines. With 800,000t annual output, grinding ball, mainly applied to metallurgical mines, are sold to Southeast Asia, Australia, Africa, North America, Central and South America and other countries and regions.

Competitive round steel mainly cover quality carbon, low alloy, alloy and high carbon grinding ball series.
