Burnrite uses A-36 steel
A-36 is a grade of steel used in many applications in the United States, the standard established by ATSM International.
As with most steels, A-36 has a density of 0.28 lbm/in³ (7.8 g/cm³). A-36 steel with a thickness of less than 8 in has a minimum yield strength of 36,000 psi and ultimate tensile strength of 58,000–80,000 psi. A-36 steel thicker than 8 in have a 32,000 psi yield strength and the same ultimate tensile strength. A36 is a standard carbon steel.
