Description
Port heavy-duty gratings are commonly used in docks, port platforms, and other heavy traffic areas. They are designed for high load conditions and long-term use. The gratings are usually made from high-strength carbon steel or ductile iron (such as GGG50), and produced by welding or casting, providing stable structure and reliable load capacity for frequent heavy vehicle use.
Surface treatment like hot-dip galvanizing or protective coating is often applied to improve corrosion resistance in marine environments. The open grating design allows for drainage and offers basic anti-slip performance for safer operation. Sizes and load ratings can be adjusted based on project needs, making them suitable for cargo handling areas, walkways, and working platforms in ports.
