1.General specification :
1) High strength and light structure.
2) Powerful anti-corrosion,durable and long working life.
3) Beautiful appearance, bright surface.
4) No dirt-rain-snow deposit,automatic cleaning. Easy maintenance.
5)Good ventilation, day-lighting,heat-dispersing, resistant to sliding and explosion.
6) They are widely used for making platform,staging, covers, ladders and fencing in many fields such as petroleum and chemical industry, electric power , water supply ,sweat treatment ,ship building ,parking lots,city construction ,environmental engineering.
Our company adopted newest technique pressed welded craft to make steel grating, The pitch between bearing bar that designed 30mm or 40mm, two neighboring cross rod is usually 50mm or 100mm.(Special specification making as client request). Using heavy hydraulic resistance automatic welding machine to weld. Then open pore, burnish and last to band. Every progressing is carefully to make.
2. Surface treatment:
Zn coating of the surface.
General Hot dipped Zn coating as GB/TB912-92, If the flat bar thickness over 5mm. Zn coating can over 600g/m2, flat bar thickness less 5mm that can over 450g/m2
3. Method of installation:
1)Welding for fixed. Welded angle at every corner of first bearing bar on grating. The seam length is about 20mm. And the height is about 30mm.
2)Fastener is available for every type of steel grating. Easy to installation,and not destroyed the Zn layer.
