Product Introduction

Ductile iron drain grates are high-performance products widely used in urban drainage systems, primarily designed to collect and discharge rainwater, preventing water accumulation and sedimentation. With high strength, corrosion resistance, and impact resistance, they are extensively used in municipal projects, industrial areas, and landscape parks. Through precise design, ductile iron drain grates can withstand various complex environments for long-term use, ensuring the stability and safety of urban infrastructure.

Product Features

1. High Strength and Load Resistance

• Tensile Strength: Ductile iron boasts a tensile strength of up to 400 MPa, ensuring it does not deform or break under heavy loads.

• Toughness: Maintains excellent toughness even in extreme weather conditions, suitable for use in main roads and industrial areas.

• Corrosion Resistance

• Anti-Corrosion Treatment: Features special hot-dip galvanizing or coating, effectively resisting the corrosive effects of rainwater, saltwater, and chemicals, ensuring long-term usage.

• Applicable Environments: Suitable for use in acidic, alkaline, and saline-alkaline soils and harsh environments.

• Good Drainage Performance

• Optimized Design: The precisely calculated opening design efficiently collects and discharges rainwater, ensuring smooth drainage and preventing water accumulation during rainy seasons.

• Anti-Blockage Design: Designed to prevent large debris from entering, reducing the risk of blockages.

• Anti-Slip Design

• Surface Treatment: The grate's surface is specially treated to increase friction, maintaining good grip even in wet conditions.

• Safety: Effectively reduces the risk of slipping for pedestrians and vehicles on wet surfaces, enhancing safety in busy areas.

• Convenient Installation and Maintenance

• Standardized Dimensions: Grate dimensions adhere to international standards, facilitating connections to existing facilities.

• Easy Maintenance: Designed for straightforward inspections and cleaning, lowering maintenance costs.

• Aesthetic Appeal

• Appearance Design: The grate features a simple and elegant design, blending harmoniously with the surrounding environment and enhancing the urban landscape.

• Customization Service: Offers customizable designs and color options based on customer requirements.

• Impact Resistance

• Wear Resistance: Maintains good wear resistance and impact performance under frequent traffic use, ensuring long-term stability.

• Heavy Load Adaptability: Maintains structural integrity under high loads and harsh conditions.
