Product Introduction:

Shanxi Jinxin Casting Group Co., Ltd.'s ductile iron manhole covers, relying on the group's full industrial chain strength and strict quality control system, are the preferred auxiliary facilities for urban roads, power and communication, residential communities, industrial parks, and other scenarios. The product range includes round and square series, compatible with load classes from A15 to D400, covering standard and customized sizes to meet the needs of different scenarios such as pedestrian paths, city arterials, and highways. Made from high-quality ductile iron materials, the graphite is evenly distributed in a spherical shape after precise spheroidization and孕育 treatment, with tensile strength exceeding 420MPa and elongation of ≥7%. Paired with zinc spray + epoxy resin double corrosion-resistant coating and sealing gasket design, the corrosion resistance is 10 times that of ordinary cast iron, capable of withstanding acid and alkali, deicing agents, and extreme temperature differences, with a service life of over 50 years. The products strictly comply with national standards such as GB/T, CJ/T, and ISO system certification, inheriting the "Shanxi Province Famous Brand Product" quality. They combine core advantages such as anti-theft locks, vibration and noise resistance, easy installation, and recyclability, support customizing appearance patterns, and are exported to many parts of the world, providing safe, reliable, and durable supporting solutions for urban infrastructure construction.
