Anti Skid Floor Forge Walkway Galvanised Steel Grating Q235 Steel
Serrated Heavy Duty Anti-Skid And Anti-Rust Catwalk Steel Grating
Steel Catwalk Grating Introduction
The corridor steel grid is also called hot dip galvanized steel
grid plate platform, platform grid plate, is a kind of steel
products with flat steel in accordance with a certain spacing and
cross bar, and welded into the middle with a square grid, mainly
used to do the drain cover plate, steel structure platform plate,
steel ladder step plate, etc.The bar is generally made of twisted square steel.
Corridor steel grid is generally made of carbon steel, the
appearance of hot dip galvanized, can play a role in preventing
oxidation.It can also be made of stainless steel.Corridor steel grille has ventilation, lighting, heat dissipation,
anti-skid, explosion-proof and other properties.

Steel Catwalk Grating Application
Corridor steel grid is widely used in petrochemical industry,
electric power, tap water, sewage treatment, port and wharf,
building decoration, shipbuilding, self-propelled parking lot,
municipal engineering, sanitation engineering and other fields
platform, walkway, trestle, trench cover, manhole cover, ladder,
fence and so on.
Steel Catwalk Grating Advantages
1, can be added in the peripheral welding kick plate (side plate),
decorative plate guard plate, installation connector and other
accessories.
2. Flat steel with different specifications of flat steel is used
to wrap the edge, or Angle steel, channel steel, square pipe and so
on.
3. Handles and hinges can be installed on the platform steel grid
plate that needs to be moved or opened frequently.
4. The edge welding standard of the corridor steel grille is: one
for every five welding series 1;Series 2, one for every four welds;Series 3 welds one per three.The weld shall be a single fillet welding of not less than 3mm, and
the weld length shall be 20mm.
Steel Catwalk Grating Production Process
Key points of steel grid welding technology
At each intersection of the load flat steel and the bar, it shall
be fixed by welding, riveting or pressure locking.2, steel grid
welding preferred to choose pressure resistance welding, can also
choose arc welding.3. The press lock of the steel grid plate can be
used to press the transverse bar into the load flat steel and fix
it.4, steel plate should be based on the needs of users, processed
into a variety of sizes of the shape.
The steel grid plate is made of flat steel in accordance with a
certain distance and bar (twisted square steel, square steel, round
steel, flat steel, etc.) for interpenetration and placement, and
welded into a kind of finished steel with square grid in the
center. The steel grid plate is mainly used to make the ditch cover
plate, the steel structure channel plate, the stepping plate of the
steel ladder, etc.The bar is usually made of twisted square
steel.The steel grid is usually made of carbon steel, and its
surface is hot dip galvanized, which can prevent oxidation.Can also
choose stainless steel manufacturing.The steel grid has the
functions of ventilation, lighting, heat dissipation, anti-skid and
explosion proof.
Installation Method
Using steel case board installation clip for installation of steel
case board with does not destroy the characteristics of the
coating, generally applicable to the often need to remove the steel
plate used above, each steel plate to be used at least four
installation clip, each corner a, for the steel plate with larger
area should guarantee per square meter of steel case board
installation amount shall not be less than 4.The steel grid plate
mounting clamp is divided into three parts: upper clamp, lower
clamp and fastening bolt.
