Rooftop Transfer Chain
Rooftop style chains are manufactured for moving bulk materials and are also commonly referred to as transfer chains. This style of the chain was implemented soon after the invention of H-Class Mill Chains to improve material handling and transferring in the aggregate and forestry industry but since then, rooftop chains are found in almost any industry and application requiring a high-strength conveyor transfer chain. Our in-stock array of rooftop chains range from rooftop roller chains to H-class mill and Engineer Class rooftop chains. We also offer a domestic made in USA line of rooftop chains! Regardless of which option you choose (domestic or import) our rooftop chains are manufactured to withstand the toughest of applications and offer an array of features and benefits depending on which size you are using.
