Frequently Asked Questions
Malleable iron is annealed cast iron, which removes the brittleness of gray iron. This makes the fittings much stronger, more ductile, and better able to withstand impact and pressure.
Yes, our products are manufactured to both NPT (National Pipe Tapered) and BSP (British Standard Pipe) standards to ensure compatibility with global piping systems.
For outdoor or highly corrosive environments, we recommend Hot-dipped Galvanized coating (ASTM A 153), as it provides the thickest and most durable layer of zinc protection.
Our malleable iron fittings are UL Certificated and manufactured according to the ASTM A197 material standard, ensuring they meet international safety and quality benchmarks.
Yes, malleable iron is widely used in heating systems due to its ability to handle thermal expansion and pressure while maintaining a secure connection.
For orders exceeding 10,000 pieces, lead times are negotiated based on the specific size mix and surface finish requirements to ensure optimal production scheduling.
