Hot Dip Galvanized Steel Grating Introduction
Galvanized steel grid plate by flat steel width 20mm - 200mm thick 2.5mm - 20mm and other welded steel grid plate for the post-heavy duty galvanized steel grid plate.
It is suitable for large cargo yard, wharf, coal mine road and bridge, etc. It can carry large truck through.
Galvanized steel grid plate (flat steel spacing 40mm) flat steel spacing 40mm steel grid plate for the most economic, the most portable varieties in the smaller span of the occasion, is the most ideal choice.
Heavy duty galvanized steel grid plate is formed by flat steel width 65mm - 200mm thick 5mm - 20mm and other welded steel grid plate for the post heavy duty galvanized steel grid plate.
It is suitable for large cargo yard, wharf, coal mine, road and bridge, etc. It can carry large truck through.
Galvanized steel grating plate (flat steel spacing 60mm) flat steel spacing 60mm horizontal bar for 50mm galvanized steel grating plate is suitable for mining and mining industry to solve the problem of mineral splashing on the surface of the plate,
Often designated for the mining processing plant galvanized steel grating (flat steel spacing 30mm) flat steel spacing 30mm galvanized steel grating for the industrial field of the most widely used varieties.
In the commonly used galvanized steel grid series, has the strongest resistance to surface impact.
Galvanized steel grating (I type flat steel) by I type flat steel welded steel grating has the characteristics of light weight, heavy load, etc.
Galvanized steel grid is suitable for all kinds of occasions, especially walkways, visiting platforms, etc.

Hot Dip Galvanized Steel Grating Application
Mainly used for industrial platform, staircase pedal, banister, channel floor, railway bridge service, high tower platform, the drain cover, manhole covers, road barrier, three-dimensional parking lot, organs, schools, factories, enterprises and institutions, the stadium fence, garden villa, also can be used as a residence outside the window, balcony guardrail, highway, rail barrier, etc.
Hot Dip Galvanized Steel Grating Advantages:
Widely used in petroleum chemical industry, tobacco industry, electricity, water, sewage disposal, port terminals, building decoration, shipbuilding, self-contained parking lot, municipal engineering, environmental sanitation engineering areas such as the platform, walkway, pier, trench cover, manhole covers, ladders, fences, stadium, exhibition center, large commercial, station, wharf, airport and other industrial and civil construction of condole top, etc.
Hot Dip Galvanized Steel Grating Process:
Steel plate process with manual welding process and welding machine process, surface treatment of hot dip galvanizing and painting, the composition of ordinary steel plate is made of flat steel and twist steel welded together, is composed of flat steel welded with special specifications, steel grid plate can be divided into common flat steel and sawtooth toothed plates, serrated flat non-slip effect is more outstanding.
Hot Dip Galvanized Steel Grating installation:
The connection mode of steel grid plate is fixed and installed with buckle connector, which is composed of three parts.
Hot Dip Galvanized Steel Grating Installation Method:
Hot-dip galvanized steel grid plate can be installed in two ways: welding and clamping.The advantages of welding are permanent fixation, not loosening, specific position in the first flat steel at each corner of the steel grid plate, the length of the weld is not less than 20mm, the height is not less than 3mm of fillet welding.The advantages of the mounting clip are that it does not destroy the hot dipping zinc layer and it is easy to disassemble. Each plate needs at least 4 sets of mounting clips. The number of mounting clips increases with the increase of the length of the plate.The safest method is to weld the screw head directly to the beam without clamping down, so that the steel grille plate will not slip from the beam due to the loosening of the clamping.
