Our Product Lineup
We manufacture polyurethane insulated rail joints, insulated rubber plates and pads used for railroad crossings, turnouts and switches. We also manufacture specialized polyurethane products for a variety of applications using rubber or steel. We provide low prices, short lead-times and we can produce specialty parts quickly.
Insulated Rail Joints
Our polyurethane is a specially formulated compound highly resistant to deterioration by ultra-violet, ozone, weathering, abrasion, or the shocks and flexing stresses of heavy rail traffic.
Insulated Tie Plates
Uniting rubber with fiber provides a combination of resiliency with strength and toughness in these insulated tie plates.
Tie Pads
Our tie pads form a tough, resilient layer between the tie and steel plate, which helps prevent tie cutting, muffles noise and cushions vibration.
Custom Molding
You dream it, we’ll mold it. We specialize in custom molding polyurethane parts to fit each of our customer’s specific requirements.
