Grey Cast Iron Grate Bar EN-GJL-200

GREY CAST IRON GRATE BAR EN-GJL-200

A grate bar refers to a series of strip holes in a combustion equipment opened by many air vents or combustion frequencies, usually made of metal materials, which can withstand constant high temperatures. The grate strip is usually located at the bottom of the furnace, can also be on the side or upper part of the combustion chamber, its role is to allow the gas and solid fuel through, promote the combustion reaction.

The grate strip produced by our company meets your customized requirements, exported to many countries, and quality assurance. The standards were performed according to EN-GJL-200.
