The term "curve" often refers to the design of the cover, which might have a curved or rounded profile, allowing for a smooth transition and aesthetic appeal.
Stainless steel is commonly chosen for these covers due to its durability, resistance to corrosion, and ability to withstand heavy loads. These covers can be designed for pedestrian or vehicular traffic, and they often have features like slip-resistant surfaces and drainage slots to manage water flow effectively. They are used in locations such as parking lots, walkways, and industrial facilities.
