Commonly used in schools, industrial settings, residential spaces, and more, steel boilers tend to be lighter in weight and lower in cost than their cast-iron counterparts. Boasting 10- to 20-year service lives, steel units are temperature-shock resistant and easy to weld into complex shapes. At Burnham Commercial, our steel units are highly customizable, so you can be confident that your order will achieve a proper fit for fast, efficient installation.
