About IRONVAULT
IRONVAULT is the export brand of Ningbo Ruitai Hardware Manufacturing Co., Ltd. We started in 2008 as a small cold-forging workshop in Ningbo, China's hardware capital, with one belief: a fastener is only as good as the trust behind it. Eighteen years on, that belief has grown into a 36,000 m² vertically integrated plant with 420 employees and six in-house production lines. From wire rod and cold forging to heat treatment, plating and packing, every step happens under our own roof — so we control tolerance, traceability and lead time instead of merely promising them. Today IRONVAULT hardware holds together wind turbines in Northern Europe, conveyor systems in Southeast Asia and automotive assemblies in North America.
