steel grating Introduction

Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar

in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension

resistance weldingring which is controlled by we can produce high quality gratings with firm

welding,smooth surface and high strength.

steel grating Details Description

1.Introduction of hot dip galvanized steel grating

1>material:carbon steel or stainless steel

2>cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.

3>Surface process of gratings: there are three types:hot-dipped galvanized ,electro-galvanized and spraying

brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film

will be formed on the zinc surface.it has good anti-corrosive property.

2.Specification of steel grating

(1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type and I-Shape type

(2)Bearing bar pitches can be 12.5, 15, 20, 30, 30.16, 32.5, 34.3, 40, 60mm, of which 30mm & 40mmare

recommended. (3)Cross bar pitches can be 38, 50, 60,100mm, of which 50mm & 100mm are recommended.

3. galvanized hot dip galvanized grating features

(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)Hot-dip galvanizing:Good antirust 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.

4. steel grating application

Steel grating used in flooring, catwalk, mezzanines/decking, stair tread, fencing, ramp, dock, trench cover, drainage pit cover, maintenance platform, pedestrian/crowded pedestrian, factory, workshop, motor rooms, trolley channel, heavy loading area, boiler equipment and heavy equipment area, office buildings, apartments, train stations, department stores, hospitals,amusement parks,etc

5.Tolerance of steel grating

The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.

6.Manufacturing process of steel grating

We have our own factory,we can ensure the quality and the competitive price,and we can manufacturer any kinds of specification as your demand.
