Everyone wants it but only Magma™ delivers the rugged construction that equals longer life. Every Magma™ Series melter/applicator is built with a six-inch by two-inch by 3/16-inch rectangular corrosion resistant tube steel frame. Tube frames offer 2.5 times the strength of “C” channels and are proven to withstand the tough duty that mobile equipment experiences. The extra thick gauge steel throughout the unit adds up to longer lasting performance and better insulating properties.
