plain steel grating/hot galvanized steel grating/bar grating:
We ,Hebei QiaoShi Grating Manufacturer, are leading exporter and manufacturer of steel grating, I-bar grating, plain grating and serrated grating, stair tread and trench cover with IS09001 quality management system approval.
1. Bearing bar pitches may be 15 to 22, 25, 30, 32.5, 34, 40,50,60,80,90mm,of which 25,30,34 and 40mm are recommended.2. Cross bar pitches maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.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 computer. So we can produce high quality gratings with firm welding, smooth surface and high strength.4. Surface Process of Gratings: there are three types: hot-dipped galvanizing , Elec-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.5. Packing Conditions of Steel Grating: Normally packed in piling up ways with two pieces of square wood on both upper and bottom sides. There are four or six pieces of M10 long bolt penetrating the gratings and screwing together. It is suitable for loading and unloading by fork-lift and crane.
Bar grating, Steel grating,steel grating plate, Expanded metal grating is specially designed with a good percentage of open gaps,and suitable for use in areas requiring good ventilation and emission of light. Its installation is easy and simple, and hence time saving. As the grating is easily cut according to required specifications, that makes the field work simple and quick. |

Steel bar grating:according to the different types of the bar, steel bar grating is mainly divided into the following three categories, their respective features are as follows: |
|
1. plain style:plain steel grating is one of the most widly applied type. Its mainly used for platforms, walkways, drainage pit cove, stair tread etc. |
|
2. serrated style: its slip resistance is better than the plain style. |
|
3. I-bar steel grating with the light weight, more economical and practical features than the plain style. |
|
The common specification: |
|
1. the type of steel grating which pitch of bars is 30mm is used most widely for all sectors of industry. It has the greates resistance to surface inpact. |
2. the type of steel grating which pitch of bars is 40mm is widely used in the industry field too. For the suitable interval of the bars so it always economical and weight-lightest. |
3. the type of steel grating which with pitch of bars is 60mm, cross bars pitch 50mm has been developed specially for mining industry and weight-lightest in all grating. In case of short spans they can meet a variety of uses. |
