Furnace grid dia.1500mm, it’s divided into 6 pcs, connected with bolt which is also heat resistant steel material, so no need worry about bolt will be broken in high temperature. We check the flatness of each piece and correct distortion if needed, after connect them with bolt, flatness will be checked again.
The advantage of 6 pcs grid is: if one piece is broken, you only need to replace one piece no need to replace the whole set of grid.
