High-Capacity Sealcoating Trailer with Extended Deck

The SR-550 Trailer with Extended Deck is built for contractors who need a durable, versatile, and high-performance sealcoating solution. Featuring a 550-gallon steel tank with 7-gauge heads and 10-gauge sidewalls, this trailer is engineered for long-lasting performance on residential, commercial, and municipal sealcoating projects.

The 2-foot extended metal deck adds extra workspace and comes with a heat shield and dual propane tank holders, providing contractors the flexibility to mount blowers, grazors, and other essential equipment for maximum productivity. The enclosed tongue and metal front deck, along with removable swing gates, keep tools and equipment secure and organized for easy access on the jobsite.

Hydraulic Agitation and Spray System

The SR-550 Extended Deck Trailer features a hydraulic agitation system with infinitely variable speeds in forward and reverse. Its full sweep, four-paddle system, equipped with 3/8” rubber wiper blades, keeps the tank walls clean and maintains consistent sealcoat suspension, even with sand-laden or heavy additive mixtures.

A 2-inch Wilden air-operated dual diaphragm pump handles high-volume, sand-heavy sealcoat, while the included 3-gallon filter pot reduces downtime and ensures steady operation. The Hannay 100-foot swivel mount hose reel with 100 feet of 3/4-inch 300 PSI hand hose and a 6½-foot aluminum spray wand gives operators excellent reach and precise control.
