Proprietary RollTrusion® Process


No single material exists to provide the strength and dimensional stability of metal, combined with the design flexibility offered by plastics. That is why Quanex Building Products invented RollTrusion®, a proprietary process that unites rollformed metal and extrusion-grade thermoplastic into a single piece, providing our customers with the best properties of the two materials – for the ultimate in flexibility and durability.

The RollTrusion process allows you to increase assembly efficiency and decrease costs while delivering enhanced performance in your finished product. Our RollTrusion process is ideal for just about any application, including mull trims and storm seals for window and door manufacturers and drawer slides for tool chest manufacturers, as well as for custom applications that require specialty shapes, sizes, colors, materials and finishes.

Take advantage of our highly skilled engineers who can design new components and tooling to exacting specifications, engage in rapid prototyping, and pilot test new products – providing you with the end-to-end support you need to bring new and innovative products to life.

At Quanex, we employ a total quality management system that includes CAD-designed profiles, high-quality steel carbide tooling and precision non-contact measurements. Additionally, our manufacturing processes are linked wherever possible to drive down labor costs and improve efficiencies. These initiatives have resulted in best-in-class quality, lead times and overall service.
