Compared with cost iron drain cover, the advantage of steel grating:
1. Saving material: the most economical method of using material at the same bearing condition, correspondingly, also less material of supporting structure.
2. Less investment: less material, less workman, shorter time limit of project, no need of clearance and maintenance.
3. Easy construction: fixed by installation fastener or welding, one person can finish.
4. Durable: hot-dipped galvanized, high attacking and heavy duty proof.
5. Modernization: beautiful appearance, reasonable design, good ventilation and daylight,
6. Light structure: less material, light weight, easy to be lifted and loaded
7. Dirt proof: no rain, no snow and dust

Steel grating mark:
1. grating, hot dip galvanized, 30*100, 6000*1000*35*5 mm, this means the bearing bar depth is 35mm, thickness is 5mm, and the bearing bar pitch is 30mm, cross bar pitch is 100mm, the length (the bearing bar direction) is 6 meter, the width (the cross bar direction) is 1m. And the surface is hot dip galvanized.
2. G 355/30/100 W F G - 6*1m
G-----grating (this can be omitted)
355-----the bearing bar depth * thickness
