Frequently Asked Questions

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

Yes, if you select the Hot Dipped Galvanized surface treatment, our flanges provide excellent protection against rust and weathering, making them suitable for outdoor use.

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

Malleable iron undergoes a heat treatment process that reduces brittleness and increases ductility, making it much stronger and less likely to crack under pressure compared to standard cast iron.

Q: Do these flanges fit standard 3/4" NPT or BSP pipes?

Our products are manufactured to meet ANSI/ASME (American) and ISO/DIN (British/European) standards. Please specify your required thread standard when ordering to ensure a perfect fit.

Q: What is the maximum load these flanges can support for shelving?

While load capacity depends on the mounting surface and pipe quality, our heavy-type malleable iron flanges are designed for industrial-grade support, making them ideal for heavy bookshelves and workbenches.

Q: How are the products packaged for international shipping?

We offer several packaging options including individual plastic film wrapping, inner boxes, and heavy-duty wooden cases to ensure no damage occurs during transit.

Q: Can I order custom sizes other than 3/4"?

Yes, our full range of malleable iron pipe fittings is available in sizes from 1/2" to 6", including elbows, tees, sockets, and nipples.
