Description of steel grating

 

Steel grating is the product in accordance with customers requirements that is lined by load flat steel and horizontal rod alternately in a certain space, welded into primary plate in the high voltage resistance welding machine, then through the deep-processing of such working procedures as cutting, slitting, tapping, bordure, etc.

 

1.Introduction of steel grating

 

1> Material: Mild Steel (Low Carbon Steel) or Stainless Steel.

 

 2> Surface Treatment:
Untreated, hot dip Galvanizing and electro galvanized.

 

 3> 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.

 

2.Steel grating specification

 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 & 40 mm are recommended. 

 3> Cross bar pitches: Maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.

4.Steel grating features

 

Attractive appearance:Simple outline.silver colour,and modern. Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron. Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free. Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety,and convenient opening. 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.Steel grating application

Steel grating may be applied to platform, floor, walkway, stair treads, trestle, fencing, drainage, trench cover, pit cover, suspended ceiling, ventilates and light through facility, etc.

 

 

7.Steel grating packing

Normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides.there are four or six pieces of M10 long bolt penetrading the gratings and screwing together.it is suitable for loading and unloading by fork-lift and crane.
