High quality steel grating (factory)

Steel grating 1.ISO9001:2000certificate 2.competitive price 3.Grating size3'x20', 3'x24', 3'x30', 1000x100

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 computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.

Steel grating&details

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

2.bearing bar pitches:maybe 12.5, 15 to 30, 40, 60, 80 and 90mm; of which 30 and 40mm are recommended.

3.bearing bar:25x3,25x4,30x3,30x4,30x5,32x5,40x5,50x5,.....75x10mm

4..thickness:0.3-2.5mm

5.surface treatment: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.

6.Material:ASTM A36,A1011,A569,Q235,275

Steel grating & features

1,Save material: save the material most bearing the same load and reduce the material of supporting

structure accordingly.

2,Reducing investment: save material, manpower, time limit for a project , avoiding cleaning and

 maintenance.

3,Construction simple and convenient: firm with screw on the installation supporting, one person

   can finish it.

4,Save the time limit for a project : the production needn’t machining again in locale and install very rapidly.

5,Durable: hot to soak zinc and antiseptic treatment before carrying out of the factory, bear the

  lash and stress.

6,Modern style: appearance attractive , design suitable ,ventilating , translucent and make

   human beings easy and smooth feelings.

7,Structure light and convenient : use material little , structure light and easy to install.

8,Avoid to accumulating dust : no accumulating rain ,ice , snow and dust.

9,Reduce the wind resistance : the wind resistance small and reducing the wind damage when windy because of good ventilating..

10,Design simple and convenient : dispense with the drawing of grille board ,only mark specification. The company can design for customers.

11,The capability of ventilating , light through a window , sending out the heat , flameproof and

    slip resistance well.

Steel grating &Usage

Our products are widely used in the national defense, chemical, construction, textile, medicine, expressway, railway, fence, breeding, mechanical equipment and other industries.

Assort:1. the grating that hte pitvh between bearing barsis 30mm,is most widely used type in industrial fiels. Among normal types,it has the strongest resistance to surface lash.

           2.the grating that eh pitch between bearing bar is 40mm is the most economical and lightest type.It is the best choice for you on occasions that the clear span is small.

           3.the grating that the pitch between bearing bar is 60mm and the pitch between cross bar is 50mm is developed specially for mining industry.It solves the problem of mineral splash on the plate.So it is often appointed to use in processing works,of mining industry.

           4.the grating with the pitch of 30mm between bearing bars and of 76mm between cross bars is the most popular type used home and abroad.It is proper for mony applications such as walkways,platforms,etc.
