EXPORT KOREA HOT GALYANIZED DRAIN COVER

It is mainly used in some factories and communities. This is mainly because the cement trench cover is often crushed and the road surface is also damaged. Therefore, the ditch cover plate made of steel grating is suitable for different load loads. Due to the simple construction of the ditch cover plate, light weight, good load bearing, impact resistance, no bending, large displacement, beautiful and durable after hot-dip zinc treatment, anti-corrosion, it has the incomparable advantages of cast iron cover plate. And adopts hinge connection or hook connection, etc., which is easy to open and has anti-theft function. It is widely used in factories and some residential areas. Since 2000, China's ditch cover market can be said to have become more widely used in some municipal roads, garden facilities, residential areas, schools, stadiums, factory construction and other different places. Regarding the design requirements of steel grid products, it has relevant instructions on steel grid products and steel grid products.

Classification of trench cover plates

Usually, we can divide the ditch cover plate into hot-dip zinc ditch cover plate, stainless steel ditch cover plate, plastic spray ditch cover plate, etc.

According to the appearance of the ditch cover plate, it can be divided into: ordinary ditch cover plate, U-shaped ditch cover plate, tubular ditch cover plate and open ditch cover plate

Features of trench cover plate

Beautiful appearance: simple lines, silver appearance, modern trend.

Better drainage: the water leakage area is 83.3%, more than twice that of cast iron.

Hot dip galvanizing: strong rust resistance, maintenance-free and replacement-free）

Anti-theft design: the cover and the frame are hinged, anti-theft, safe and easy to open

Save investment: when large span, heavy load, lower than cast iron price and save the cost of stolen or crushed replacement

High strength: The strength and toughness are much higher than cast iron, which can be used in large-span and heavy-load environments such as docks and airports.

Many specifications: meet the needs of different environments, loads, spans, sizes and shapes

The product has the advantages of simple construction, light weight, good bearing, impact resistance, bending and not folding, large displacement, beautiful and durable after hot-dip zinc treatment, anti-corrosion, and incomparable advantages of cast iron cover plate. Hinge connection or hook connection is adopted, which is easy to open and has anti-theft function.

Steel grating hook cover

GT-type steel grating trench cover is divided into side trench cover and cross-cut trench cover according to the direction of the vehicle. The bearing flat steel direction perpendicular to the vehicle direction is called the side ditch cover, and the bearing flat steel parallel to the vehicle direction is called the cross-cut ditch cover.

GT-type ditch cover is suitable for road occasions other than highways, and the general traffic flow is not large. When used as a cross-cut trench cover, the risk of cover plate jumping should be considered, and bolt-fixed trench cover should be adopted. GT-type steel grating trench cover is suitable for trench with support along the opening (T-type trench), and angle steel is usually used for protection along the opening.

GT-type steel grating trench cover is suitable for ditches with supports along the opening (T-shaped trench), which is usually covered by angle steel

GU type trench steel grating trench cover

GU type trench steel grating trench cover

When it is necessary to cross the car, the GU-shaped trench grille trench cover is only suitable for side trenches

GM type wellbore steel grating cover

In order to improve the impact resistance, GM well hole steel grating cover is generally made of steel grating with a cross bar spacing of 50mm
