A grating is a structure made of metal or other materials, designed in a lattice form. While the term "grating" might not be commonly heard, we frequently encounter such structures in our outdoor environments, notably as lattice-shaped metal covers on road drainage gutters.
Gratings allow rainwater to enter gutters while preventing objects, feet, and car tires from falling in. They are increasingly used as flooring material within residential buildings.
Gratings serve various purposes:
Gratings cover gutter tops to prevent obstruction by large debris and accidents involving feet and tires. They play a crucial role in maintaining the functionality and safety of drainage systems.
As floorboards for corridors and landings, gratings allow sunlight from upper floors to reach lower levels, enhancing natural light inside homes.
In industrial settings, gratings are used as floor plates for access and maintenance of equipment, offering superior load-bearing capacity compared to other materials like checker plates. They are also utilized for stair treads.
Gratings provide a durable and safe flooring option for the inspection and maintenance of outdoor and indoor machinery.
Gratings are structured materials made of steel or other elements, assembled in a grid pattern. They consist of main bars (load-bearing members), end plates, and twist bars that ensure the spacing, verticality, and parallelism of the main bars.
Main bars, including flat and I-bars, are crucial for the grating's load-bearing capacity. Their dimensions are selected based on the expected load.
End plates are welded around the grating to enclose the main bars, using flat bars or L-shaped steel for added stability.
Twist bars maintain the main bars' spacing and alignment. They are essential for applications requiring specific spacing for safety, like preventing bicycle wheels or baby strollers from getting stuck in road drain covers.
Gratings are categorized into four main types based on shape and application:
This type is commonly used for roadside ditch covers, often fixed with bolts to ensure stability in high-traffic areas.
Raised gratings offer versatility for various groove types, featuring longitudinal legs that elevate the grating.
Used for catch basin lids, this nearly square-shaped grating fits similar frames, providing secure coverage.
U-shaped gratings cover grooves without steps, easily fitting over the groove for simple installation.
To prevent rust, gratings undergo surface treatments like hot-dip galvanizing, aluminum alloy plating, or nylon coating, enhancing durability and aesthetics.
Stainless steel and FRP gratings are alternatives for environments requiring corrosion resistance or aesthetic appeal.
Gratings come in coarse and fine spacing options, with anti-slip surfaces for safety in pedestrian areas.
