The primary advantage of plastic gratings lies in their resistance to corrosion. Unlike traditional metal gratings, which can rust or corrode over time, especially in harsh or wet conditions, plastic gratings maintain their integrity and strength even when exposed to chemicals, saltwater, or extreme weather. This makes them perfect for use in industrial settings such as chemical plants, oil refineries, and wastewater treatment facilities, as well as coastal areas and bridges where exposure to corrosive elements is high.

A hexagonal drill rod, as the name suggests, features a hexagonal cross-section rather than the conventional circular one found in standard drill rods. This design alteration is not merely aesthetic; it serves a functional purpose that significantly enhances performance. The hexagonal configuration provides greater surface area, which in turn increases the contact area between the rod and the drilling machine. This results in better torque transfer, reducing slippage and enhancing overall drilling stability.
