About us
The history of our company dates back to the 1980s, beginning with Jinji Foundry, located in Hebei Province, China. To meet the growing demand for international trade, Tianjin In Rich Casting Co., Ltd. was established as the export arm of Jinji Foundry, with a focus on bringing high-quality cast products to the global market.
Unlike many trading companies, we manufacture all our products in our own factory, giving us full control over quality, lead time, and customization. Over the years, we have evolved from a traditional manhole cover producer into a modern enterprise equipped with multiple dedicated casting lines and experienced technical staff.
Our products—primarily ductile iron manhole covers, trench grates, and steel gratings—are exported to Europe, and Southeast Asia. In particular, we have earned a strong reputation in the Southeast Asian market. In Thailand, for example, our products account for approximately 80% of the market share, making us one of the most trusted suppliers in the region.
To better support our clients and localize service, we established a branch office in Bangkok, Thailand in 2018.
With decades of manufacturing experience, a commitment to strict quality standards, and a strong focus on international partnerships, we continue to grow as a reliable manufacturer and direct exporter in the global casting industry.
