Drainage efficiency is key in many areas of both modern Infrastructure and Urbanisation as well as manufacturing. The core of any successful drainage system is the use of Gratings for drains, which help manage surface water, prevent accidents, and protect underneath drainage channel systems.
Gratings for drainage are found in virtually all kinds of structures, whether they are factories, highways, commercial buildings, residential projects, or more.
This guide explains what Drainage Gratings are, the different types and materials available, their uses, and how to select a manufacturer of Drainage Gratings when sourcing products from India or Gujarat.
What Are Gratings for Drains?
A grating is simply a protective cover to help drain (drain) water from a facility to ensure proper collection, as well as to keep large items from getting into the system and creating blockages. At the same time, the grating provides a safe and durable load-support surface for pedestrians, vehicles, and industrial equipment.
The terms drain grating and drainage grating can be used interchangeably; however, there is a difference. Drain grates typically refer to smaller, localised cover systems, while drainage grating is a broader term for larger and more heavy-duty cover systems typically used for industrial or large-scale infrastructure projects.
How Drainage Gratings Work
Drainage grates provide efficient management of stormwater, while providing a safe load-bearing surface underneath busy pedestrian, vehicle, and industrial traffic. Drainage grates are designed to distribute the water that flows into the drainage system, and at the same time distribute the load that is placed on top of them.
When properly designed, a drainage grating maximises water flow capability, provides a safe, durable load-bearing surface, and minimises the risk of structural failure.
Types of Gratings for Drainage Systems
Different environments require different types of gratings based on load, exposure, and usage.
Metal Gratings for Drains
Drains are another application of the metal grating products. They also include welded steel and press-locked steel gratings. Steel gratings are strong enough to support a large number of weights and withstand a large number of industrial drainage applications such as production plants and factories, in addition to being commonly used in many industries that require heavy-duty construction.
Ductile Iron Drainage Gratings
Ductile iron drainage gratings are engineered and produced to handle the heaviest load cases (heavy-duty). They are applied most commonly to highways and roadways, airports, and municipal stormwater drainage.
Ductile iron drainage gratings provide excellent strength and stability when being subjected to extremely heavy traffic loads, and continue to perform well over an extended period of time.
(SS)Stainless Steel Drain Gratings
Stainless steel gratings have excellent properties of corrosion resistance and are hygienically clean. Stainless steel drain grates are commonly employed in a wide variety of food-processing facilities, as well as pharmaceutical manufacturing plants, hospitals, and chemically or environmentally sensitive controlled environments.
Trench / Linear Drain Gratings
Trench/linear drain gratings, also known as trench or linear drains, are used for continuous drainage applications.
Trench drains are typically used in parking lots, municipal stormwater drains, office buildings, and airports, and are very effective in managing a large volume of surface water.
Benefits of High-Quality Gratings for Drainage
The usage of high-grade drainage gratings provides benefits, both from a practical usage point of view and from an economic standpoint.
Water Drainage and Flow are being Optimized
The design of a grate influences the speed of the flow of water into a drainage pipe. Due to this, the design of the grate will minimize the occurrence of waterlogging, flooding and other types of surface damage – particularly during heavy rain events.
Durability, Load Capacity, and Strength
High-quality grates are manufactured to meet specific load classifications (e.g. pedestrian, light duty, heavy duty, etc.). Therefore, high-quality gratings will provide long-term service and decreased replacement expenses.
Safety and Resistance to Corrosion
Properly designed drainage grates increase safety with a non-slip surface and an extensive design using the latest technology to ensure longevity and durability in all conditions, including extremely wet or very humid areas (such as coastal regions) and those exposed to the harsh elements of nature.
Corrosion-resistant materials are also used to ensure the performance of the grate in any type of harsh or corrosive outdoor environment (i.e., salt water, industrial environments, etc.).
How to Choose the Right Gratings for Your Drain Application
When selecting a drainage grating, there are several things to consider.
Material Choices
Galvanized Iron: This type of grating is inexpensive and commonly used in industrial and commercial applications.
Stainless Steel: If you need a grating that can withstand corrosion or is hygienic, then stainless steel is your best bet.
Ductile Iron: Ductile Iron gratings offer the highest load-carrying capacity, so they are very good for areas with heavy traffic and support large infrastructure projects.
FRP (Composite): These are lightweight and provide excellent resistance to chemicals.
You want to start by determining what type of operating environment the drainage grate will be installed in when choosing the appropriate material.
Selecting the Right Load Class and Drainage Grating
Load classes are used to define the maximum amount of weight a grating can hold without failure. Light-duty gratings are best for pedestrian walkways, while medium- and heavy-duty gratings should be used in parking lots, factories and on roads. Selecting the correct load class prevents premature failure and keeps people safe.
Slot Size, Design, and Standards
Slot sizes need to be designed so that water flows freely, but also do not present tripping hazards or foot entrapment. Most projects will also fall under certain design and performance criteria specified by various regulations, including EN 1433, the standard that specifies the definitions of load classes and performance standards for drainage grating systems.
Applications of Gratings for Drains
Gratings for drainage are covered by multiple industries and are used for many different types of industrial applications, including but not limited to:
Industrial Applications
Many Industrial Applications (such as Manufacturing Plants, Refineries, Power Stations, and processing plants) depend on strong and reliable drainage systems, which are used to direct and collect water and chemical waste generated from the manufacturing and/or production process.
Commercial & Infrastructure Use
Airports, Parking Lots, Shopping Malls, and Public Parks all have a large surface area that is exposed to heavy rain and vehicular traffic. To achieve this goal, drainage gratings are an essential component of the proper management of surface water.
Urban & Residential Drainage
Many Urban Cities and Residential Neighborhoods have drainage systems, or “Storm Water” (drainage) Grates located near their Footpaths, Driveways and Houses. In addition to being an essential part of drainage systems, such drainage gratings are an integral part of stormwater management strategies, by allowing runoff water to drain away from the surface of the ground and into the surrounding area.
Material Comparison – Which Drainage Grating Is Best?
Depending on where they are used, each type of material has its own advantages and disadvantages.
- GI (galvanized iron) gratings: These are inexpensive, offer good strength characteristics, and can generally be used in various industrial applications.
- Stainless steel gratings: These gratings have high corrosion resistance, are easy to maintain hygienically, and are used best used in sterile/clean environments.
- Ductile iron gratings: These gratings are rated to be very strong and can be used primarily in applications related to roads/infrastructure.
- FRP (fibreglass-reinforced plastic) gratings: These gratings are lightweight, will not corrode, and can therefore be used in caustic environments (i.e., exposed to corrosion from chemicals).
There is not a “best” option, but rather a “best” option for the respective environment and load requirements.
