Steel Grating full introduction and applied as trench drain

Steel Grating is a kind of open steel member with its bearing bars&cross bars jointing at their intersections either by welding or by locking. It is weighty with strong pressure resistance, which makes it widely used in kinds of flooring,stairtread, trench cover, drainage pit cover and so on. Regarding surface treatment, hot-dip galvanizing, paint or other anti-corrosive coating are available, of which hot-dip galvanizing is generally recommended.

Steel grating is hot dip galvanized processing, offers the following advantages: saving materials,saving investment, easy installation, durable in use, light structure, no accumulation of dirt, good performance of ventilation, lighting, heat dissipation, anti-corrosive, anti-acid an alkali corrosion.
The products are used in such industries as petroleum and chemical, port, power, transportation, paper making, medicine, steel and iron, food, municipality, real estate, manufacturing, etc.

Steel grating characteristics
1.Attractive appearance: Simple outline. silver colour, and modern.
2.Optimum water draining:Water leakage area reaches 83.3%, which is more than two times larger than that of cast iron.
3.Good anti rust performance,maintenance free and replacement free.
4.Design of preventing theft:The cover is connected with the frame by gemel, which ensures protection against theft, safety, and convenient opening.
5.Saving investment: With large span, the cost is lower than that of cast iron when under heavy load. And the replacement expenses in case of theft and crushing will be saved.
6.High strength: With strength: With strength and toughness far higher than those of cast iron,it can be used in the environment with large span  and heavy load, such as the wharf and the airport.
7.Many specifications available: The requirement of different environments, loads, spans, sizes and shapes can be satisfied.

Floor Ventilation Grilles
Grating trench cover is applied on walkway,carriageway,court yard etc, used as cover for drainage trench,wire ditch,subway and air pit.Hop-dip-galvanized finish is used as antisepic.

Grating trench cover is composed of fixed frame & movable grating.It can be classified to GT & GU according to structures.

Grating trench cover is used foe catch basin,sand sediment trap,draining well,&sink hole in roads, park&other civil projects.It's generally designed to be revertible & its start-stop angle is 110°.Higed trench cover has good advantages on anti-theft and installation.

GU Trench Cover:
Regarding most concrete groove without edge,it would be very simple and economical to use GU trench cover for there is no special requirements to groove edge. It's suggested that angle steel should be filled in upper edge,if the loads are T-6 and T-4,The U trench prefab blocks are also available to prevent dirty water to leak in to earth.But GU trench cover is just suitable for side dictch when a car need to cross it.

Compound Stainless Steel Gratings Aluminum Composite Panels

Compound steel grating is composed of checkered plate on sealed surface&steel grating with certain spanning capability.

Compound steel grating is formed of any type steel grating and checkered plate in different thickness.The type JG323/40/100,JG323/60/100 are generally used as base&the checkered plate with 3mm thickness is used as sealing plate.Sometimes checkered plate with thickness of 4mm,5mm or 6mm is also used as sealing plate according to customer's requirements.

Note: As thermal stress may cause shape distortion after hot-dip galvanized treatment,especially when choosing large spacing grating,it's not easy to flatten.So special attention should be paid when choosing grating types.


More about steel grating:
Steel grating, or steel grates, is made of carbon steel or stainless steel. Carbon steel grating, is lighter and cheaper than steel grating, as it material grade is lower than that of stainless steel. Stainless steel grating is smooth at surface, it’s much more expensive than carbon steel grating. Most customers prefer carbon steel grating more than stainless steel grating. Steel grating is made of bearing bar and cross bar, while the cross bar is twisted bar, and it adopts welding or pressure lock for composing. 

Regarding on surface treatment, coating, hot-dipped galvanizing and untreated are available for carbon steel grating, in which hot-dipped galvanizing is commonly recommended. For stainless steel grating , it usually doesn’t need any surface treatment as it is smooth and anti-corrosive.  

Unlike aluminum grating, steel grating is usually made to stair tread and trench drain, as it is strong enough and it’s heavy to carry as a large one. Steel grating could be fabricated to many shapes and sizes, just according to customers’ requirements. Such diamond grating, I-bar grating, pressure locked grating are all available. 

Steel grating is an orthogonal steel combination with flat bearing steel and bars in accordance with a certain space, fixed by welding or pressure lock. Crossbar generally uses the twisted square steel, round or flat steel is also available. As for the material, it can be divided into carbon steel and stainless steel. Stainless steel grating is usually made as platform board, trench cover, treads ladders, ceiling buildings. Steel grating generally is made of carbon steel, with hot dip galvanized appearance which plays an important role in preventing oxidation. It can also be made of stainless steel. Steel grating has the good performance of ventilation, lighting, anti-slip, explosion-proof. Stainless steel grating is applicable to alloys, building materials, power plants, shipbuilding, construction and other industries. It is beautiful and durable, easy to clean, easy to install.

Steel Grating-power Plant/Building Channel/Shelf of Steel Grating

Steel grating is a bearing in a certain space and bar (twisted square steel, twist steel, flat steel, and so on) are staggered orthogonal composite soldering or compression lock fixed, welded into the middle with a square lattice steel, cut, cuts, holes, hemming processes deep processing products made to customer requirements. Mainly used for steel structure platform, steel treads and a variety of ditch cover plate, and so on. According to different production methods can be divided into two kinds, one is a pressure welding of steel grating, made of flat steel and Rails made by pressure resistance welding, and the other is locked using latitude and longitude are flat steel made of steel grating. Finished steel plates by hot-dip galvanizing process in General can play a role in preventing oxidation. Can also be made of stainless steel production. Administered under the same amount of steel and accordingly reduce the support structure of the material. Save money, simplify the installation process. No accumulation of rain, snow and dust, from cleaning and maintenance-free. Many projects have very widely used in the country.

Steel gratings selection should take fully into account the different environments, different cost factors of bearing capacity and cost.
