Drainage, water intake, and rain grates are all different names for the same element of surface water drainage, the main purpose of which is to reliably cover water drainage channels. All rain grates bear large mechanical loads, reducing the impact on the channels themselves and thereby extending their service life. Depending on the material of manufacture and strength index, grates are classified into load classes from A to F, which characterize their ability to withstand loads of a certain level. It is also important to consider the decorative value of this element of the surface water drainage system, as it allows even a not very pleasant concrete channel to easily blend into the overall landscape atmosphere.
Main functions of drainage grates:
Protective (reliably protect against large debris entering the channel). The grate openings allow water to pass through unhindered while trapping debris, leaves, and branches.
Decorative (grates fit well into the overall appearance of the area, beautifying even not very attractive concrete or plastic channels).
Practical (thanks to the grates, people, animals, or vehicles can safely pass through the channel passage).
Advantages and disadvantages of grates made of different materials
Modern technologies allow the production of drainage grates from cast iron, stainless steel, durable plastic, or even copper. The strongest and most reliable of them are cast iron grates, capable of withstanding maximum loads and used in areas with heavy vehicle traffic, at cargo terminals, etc., where they can withstand maximum mechanical loads. In pedestrian areas, grates made of durable plastic are most commonly used – a fairly reliable, economical, and visually appealing option. In the food industry, grates made of stainless or galvanized steel, resistant to aggressive environments, are used. Each type of material has its advantages and is intended for use in specific conditions.
