Solid-POLY™

The body that won’t rust, rot, or let you down.

Corrosion resistance that pays dividends for decades.

Spencer’s Solid-POLY™ body is engineered for departments that need long-term durability without sacrificing customization, storage, or operational flexibility. Unlike traditional materials that can corrode over time, Solid-POLY™ is designed to withstand harsh environments, road chemicals, moisture, and daily wear while maintaining structural integrity for the long haul.

Its corrosion-free construction helps reduce long-term maintenance concerns while delivering the strength and durability departments depend on in demanding conditions. The material is also highly resistant to impact damage, helping the apparatus hold up to the realities of everyday operation.

Beyond durability, Solid-POLY™ gives departments greater flexibility in how a truck is designed and configured. The construction allows for more advanced compartment layouts, complex body designs, and efficient use of available space helping maximize both water capacity and equipment storage without compromising usability.

Every Solid-POLY™ body includes a lifetime warranty on the body, tank, and substructure, providing long-term confidence in the truck’s performance and durability.
