Perma Tech Dock Seals are constructed with the highest quality components to ensure the most effective seal possible at the loading dock door.
All lumber backboards are pressure treated to prevent rotting, and our polyurethane foam is the ideal density to form an airtight seal against the trailer. The foam's high resiliency prevents foam "sag", maintaining the seal's neat appearance and performance over time. The most critical component in determining the useful life of a dock seal is the covering material. Perma Tech's products are constructed with high tear vinyl fabrics, available in all varieties of weights and colors.
A tight dock seal reduces heating and cooling costs, improves loading safety, security, and will protect your products from the elements. Our custom designed seals are built to suit every dock situation - from light volume traffic to the heaviest traffic.
