Frequently Asked Questions

What distinguishes ductile iron from other materials used in floor drains?

Ductile iron contains graphite nodules that give it higher tensile strength and ductility compared to gray cast iron. This means it can bend slightly under stress rather than breaking abruptly, making it much safer and more durable for high-load applications. It also offers better vibration damping properties, which reduces noise during vehicle passage.

Are these floor drains suitable for outdoor use in freezing climates?

Yes, the heavy duty ductile iron floor drain covers are designed to withstand extreme temperature variations. The material does not become brittle in cold weather, and the anti-corrosion coatings protect against ice melt chemicals commonly used in winter. Proper installation with adequate slope and drainage connection is recommended to prevent ice buildup.

How do I determine the correct load class for my project?

The load class depends on the type of traffic expected over the drain. For pedestrian areas, lighter classes (A15 or B125) are sufficient. For car parks and roads, medium classes (C250 or D400) are required. For heavy industrial areas or airports, the highest classes (E600 or F900) are necessary. Our technical team can assist in selecting the appropriate class based on your specific usage requirements.

Can the surface pattern be customized?

Absolutely. We offer a variety of surface textures and patterns, including diamond plate, smooth, and custom logos. Customization allows the drain to blend with the surrounding flooring material, whether it is tile, concrete, or stone, ensuring a cohesive architectural look.

What maintenance is required to keep the drains functioning optimally?

Maintenance is minimal. Regular inspection of the grating for debris accumulation is recommended, especially in areas with high organic matter or sand. The removable cover design allows for easy cleaning of the underlying sump basket.
