Computing method of area of aluminum grating
1. The area of aluminum grating is calculated based on the overall dimension according to the drawing of grating supplied by customers and it includes the open pore and the incision.
2 .As for uncommon aluminum grating shown in the following diagram, the area equals width × length, with the cut part included.
1. Preparing the raw material
2. Punching the bearing bar
3. Assembling by put the smaller bearing bar into the punched hole and welding
4. Banding and welding
1. All welds must have a single fillet around
2. All welding between grating plate and boundary must be single fillet welds
