Hot Dip Galvanized Steel Grating Introduction
Hot dip zinc steel grille is the steel grille production after the hot dip zinc antirust treatment.
There are two kinds of hot dip galvanizing and electric galvanizing.
Hot dip galvanized steel grid according to the production process, divided into pressure welding hot dip galvanized steel grid and pressure lock hot dip galvanized steel grid;
According to the surface shape of hot dip galvanized flat steel, it can be divided into toothed hot dip galvanized, planar hot dip galvanized, I hot dip galvanized and compound hot dip galvanized steel grid.
Hot dip galvanized steel grid according to the manufacturing process, divided into welding hot dip galvanized steel grid and pressure lock hot dip galvanized steel grid;
According to the surface shape of hot dip galvanized flat steel, it is divided into toothed hot dip galvanized, planar hot dip galvanized, I hot dip galvanized and composite hot dip galvanized steel grid.

1. Flat steel: the material is Q235A or stainless steel, with ordinary plane type, anti-skid tooth type and section I type.
Common specifications are 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, 100*10 and so on.
2. Bar: round steel, twisted square steel, square steel or hexagonal steel made of Q235A or 304 stainless steel.Twisted square steel is made by drawing and twisting the square die, and its common specifications are 5*5, 6*6, 8*8mm, etc.
Hot Dip Galvanized Steel Grating Application
Uses: Widely used in petrochemical, power plant, water plant, sewage treatment plant, municipal engineering, sanitation engineering and other fields of the platform, walkway, trestle, ditch cover, manhole cover, ladder, fence, guardrail, etc
Hot Dip Galvanized Steel Grating Advantages
Features: high strength, light structure: the solid grid pressure welding structure makes it has high bearing capacity, light structure, easy to hoisting and other characteristics;Beautiful appearance, durable: hot dip zinc surface treatment makes it has a good anti-corrosion ability, the surface luster is beautiful;Good ventilation, lighting, heat dissipation, explosion-proof and skid proof performance;Prevent accumulation of dirt.
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.
