Hot-dipped Galvanised serrated steel bar grating
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.
 
 
Material: Mild Steel (Low carbon steel) / Stainless steel
Plain style steel grating, Serrated style steel grating and I bar type steel grating,
Finished:painted/hot dip galvanized, untreated, painting
 
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.
