Ductile Iron Manhole Cover

The Ductile Iron Manhole Cover from Yadite Cast Group Ltd is manufactured to EN 124 standards, with load classes ranging from A15 to F900 as defined by the product's application zones. Each cover is cast from nodular iron with a minimum tensile strength of 420 MPa and elongation of at least 10%, ensuring durability under dynamic loads. The exact dimensions and weight vary by class, with D400 covers typically measuring 700 mm in diameter and weighing approximately 95 kg.

These covers are produced using sand casting with controlled cooling to maintain microstructural integrity, resulting in consistent mechanical properties. The surface finish is machined to a smooth tolerance of ±0.5 mm, and the edges are chamfered to prevent chipping during handling. Standard coatings include bituminous paint or epoxy resin for corrosion resistance, though bare cast iron is available for internal or low-moisture environments. The material composition conforms to ASTM A536 Grade 65-45-12 or equivalent, with carbon content between 3.2% and 3.8% and magnesium content controlled to 0.03% - 0.06% for nodularization.

These covers are primarily purchased by municipal infrastructure contractors, airport authorities, and civil engineering firms in regions with high traffic or heavy vehicle loads. Buyers typically order in batches of 10 - 50 units, with packaging in wooden crates or steel pallets. Trade terms are commonly FOB Cangzhou Port, with lead times of 25 - 35 days after deposit. Custom load ratings and non-standard sizes are available upon request, subject to minimum order quantities confirmed directly with the supplier.

Yadite Cast Group Ltd operates from Cangzhou City, Hebei Province, China, with a production facility focused on ductile iron castings for civil infrastructure. The supplier is verified as a harbor-tier trading company with a documented export history in cast iron products. There is no public data on factory size, employee count, or annual turnover. The listing confirms active export experience but does not claim certifications such as ISO 9001 or CE marking, nor does it list specific clients or project references.

The supplier's primary capability is casting and finishing ductile iron manhole covers to international load classifications. They do not state whether they offer in-house testing equipment, third-party inspection, or design customization beyond standard EN 124 variants. Their response rate and average response time are not recorded, indicating limited or inactive communication channels. Buyers should treat this as a manufacturer-exporter without verified quality management systems unless confirmed directly.
