Cast Iron Manhole Step for Enhanced Stability and Corrosion Resistance

Product Features:

High-strength ductile iron material:
Made of ductile iron (such as EN-GJS-500-7 or QT500-7), it has excellent tensile strength, ductility and impact resistance, and can withstand high loads and frequent use.
Compared with traditional cast iron, ductile iron is more durable and relatively light.
Excellent corrosion resistance:
The surface has been treated with anti-corrosion (such as hot-dip galvanizing, asphalt coating or spray epoxy resin), which can effectively resist the erosion of moisture, chemicals and acid-base environment and extend the service life.
Humanized design:
The ladder's rungs (pedals) are ergonomically designed and have anti-slip patterns on the surface to ensure the safety of construction workers when climbing in wet or muddy environments.
Rounded corners avoid sharp edges and reduce damage to construction workers' hands and feet.
Strong load-bearing capacity:
The ductile iron material itself has good mechanical properties. The ladder can withstand large vertical loads and lateral impact forces, and is suitable for high-intensity use occasions.

Standardization and modularization:

It can be produced according to standard dimensions or customized according to user needs to adapt to the sizes and shapes of various shafts or inspection wells.

The modular design is easy to install and disassemble, and convenient for later maintenance and replacement.

High safety:

The ductile iron ladder is firmly installed, and the ladder frame is stable and not easy to shake, ensuring the stability and safety of construction workers when climbing.
