Brief 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 computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.
Steel Grating Informations:
1. Material:LOW CARBON STEEL PLATE
2. surface treatment: hot-dipped galvanized ,electro-galvanized and spraying brushing and soaking.
3. cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
4. bearing bar pitches:maybe 12.5, 15 to 30, 40, 60, 80 and 90mm; of which 30 and 40mm are recommended.
5. bearing bar:25x3,25x4,30x3,30x4,30x5,32x5,40x5,50x5,.....75x10mm,etc
6. thickness:0.3-2.5mm
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 application:
Steel bar grating are widely used in the national defense, chemical, construction, textile, medicine, expressway, railway, fence, breeding, mechanical equipment and other industries.
