Also known as spheroidal graphite grate bars, our SG grate bars, are a type of grate bar commonly used in industrial applications, particularly in solid fuel combustion systems. They are made from spheroidal graphite iron, a type of cast iron that offers enhanced mechanical properties and increased resistance to heat and wear. These are designed to withstand the demanding conditions of combustion processes, ensuring efficient fuel burning & reliable operation of furnaces, boilers, and more. SG grate bars are known for their high strength, durability, and resistance to thermal stress and corrosion.
