How to choose trench drain covers correctly?

Drainage ditch covers are used in many places in our daily life, and there are many types of trench drain covers according to the raw materials used.

1. Here are some tips for choosing trench covers:

1. For trench covers used on sidewalks, roadways, parking lot steel gratings, docks or building floors on traffic roads, due to different loads and driving directions, their design and selection should be considered in actual conditions.

2. When used for ditches and cross-sectional trench covers on roads (the driving direction is parallel to the direction of the load-bearing flat steel), not only wheel pressure and impact should be considered, but also the danger of rebound and displacement of the trench cover should be prevented. The trench cover must be fixed to the angle steel and support beam (it can be fixed by welding or steel grating installation clamps). Light duty: 25 tons/m2; campus residential parks, parks, underground parking lots and kitchens with cars and pedestrians; Heavy duty: 70 tons/m2; factory areas with cars under 20 tons, general roads, roadsides of main roads, parking lots and streets; Super heavy duty: 140 tons/m2; main roads with heavy trailers, container forklifts, cranes and airplanes, extra-large parking lots, mines, docks and airports.

2. Characteristics and application scope of drainage ditch covers

Drainage ditch covers are also called "ditch covers" and rainwater grates. They are welded with steel grating plates. They are simple to install and construct, light in weight, good in load bearing, good in impact resistance, and good in bending rather than breaking. They have large drainage capacity. After hot-dip galvanizing, they are beautiful and durable, anti-corrosion and anti-rust, and have incomparable advantages over cast iron ditch covers. Because the steel grating is connected by hinges, it is easy to open and has anti-theft functions.

3. Characteristics of drainage ditch covers

Drainage ditch covers are made of steel grating plates, and there are many types to choose from to suit different span loads and requirements. According to the shape of the drainage ditch cover, it can be divided into: ordinary ditch cover, U-shaped ditch cover, tube-shaped ditch cover and openable ditch cover. Characteristics of drainage ditch covers: beautiful shape: simple lines, silver surface; leakage area reaches 83.3%, more than twice that of cast iron; hot-dip galvanizing: strong anti-rust ability; the cover and frame of the drainage ditch cover are connected by hinges, which is anti-theft, safe, and easy to open; large span, heavy load, lower than the heavy load quotation. Drainage ditch covers can be used in large span and heavy load environments such as docks and airports.
