Product Features:

  • Advantages: SlipNOT® expansion joint cover plates are approved and used by the Florida Department of Transportation (FDOT) and the Texas Department of Transportation (TxDOT) due to the extreme surface hardness, durability and longevity they provide.
  • Availability: SlipNOT® expansion joint covers are custom formed in order to meet specific project requirements.
  • Care: The most effective cleaning method is with a steam cleaner or power washer. Debris can be removed with a stiff bristle brush. SlipNOT® recommends testing any chemical cleaning agent on a sample provided by SlipNOT® to verify that it is safe to use on the SlipNOT® surface.
  • Durability: Galvanized steel plate has a file hard surface between 55 – 63 on the Rockwell “C” scale and a bond strength of at least 4000 psi.
  • Fabrication: Galvanized steel plate can be sheared, welded, flame cut, torch cut, laser or water-jet cut, plasma cut, countersunk, and drilled for complete versatility, both in the shop and field. When fabricating or working with our product, it can be treated like any other metal plate or grating. (Fabricating Specifics) After welding galvanized products together, the welds must be cold galvanized in order to prevent rust.
  • Slip Resistant Standards: Galvanized steel expansion joint covers meet and exceed all the requirements for an ASTM / ANSI slip resistant surface and is registered slip resistant with Underwriters Laboratories per the UL 410 standard. SlipNOT®’s coefficient of friction is greater than or equal to 0.85.
