Frequently Asked Questions

Q: What is the difference between malleable iron and standard cast iron fittings?

Malleable iron undergoes a heat-treatment process (annealing) that removes brittleness, making it significantly stronger and more resistant to impact and pressure than standard grey cast iron.

Q: Can these floor flanges be used for outdoor furniture?

Yes, especially our Hot Dipped Galvanized versions which provide superior corrosion resistance. For black iron, we recommend a clear coat or paint to prevent rust in humid outdoor environments.

Q: Do you support custom sizes beyond the standard 1/2" to 6"?

While we specialize in standard ANSI, BS, and DIN dimensions, we can accommodate specific customer requirements for bulk orders. Please contact our engineering team for custom specifications.

Q: What threading standards are available for your pipe fittings?

We provide a wide range of threading options including BSP (British Standard Pipe) and NPT (National Pipe Thread) to ensure compatibility with global plumbing and furniture systems.

Q: How are the products packaged for international shipping?

To ensure zero damage, we use nylon bags, standard export cartons, and secure wooden cases or pallets, depending on the order volume and client preference.

Q: Which industries typically use your malleable iron floor flanges?

Our flanges are widely used in the metal products manufacturing industry, commercial interior design (Industrial Style), plumbing for gas/oil/air, and architectural railing construction.
