Rhino-Dek^® Bridge Deck

Steel bridge decking with protective coating for aggressive environments

Polymer laminate over galvanized steel protects Rhino-Dek^® against salt corrosion

The added-benefit of Rhino-Dek® comes from polymer laminate—available on one or both sides of the deck pan—over galvanized steel. The combination makes Rhino-Dek® resistant to salt, whether it’s direct splash, fog or road salt in the winter. Rhino-Dek® is also abrasion- and ultraviolet-resistant. The protective coating of Rhino-Dek® can extend bridge service life in aggressive environments to 124 years.

Rhino-Dek® polymer-laminated bridge deck forms

Ideal for spans over brackish and salt water, Rhino-Dek® stay-in-place bridge deck forms are specially designed to protect exposed steel from salt corrosion. Rhino-Dek® can be used in both concrete and steel bridge structures, for new bridge construction or bridge rehabilitation. More than a long-lasting bridge deck solution, Rhino-Dek® stay-in-place bridge deck forms also provide significant cost and time savings.

Engineered for performance and safety

All deck and accessories are fabricated from steel conforming to ASTM Specification A-653 Grade 50 having a minimum coating class of G165 according to ASTM Specification A-924. The steel unit working stress will not exceed 0.725 of the specific minimum yield strength or a maximum of 36,000 psi.

Both Bridge-Dek® and Rhino-Dek® are designed based on the applicable dead load (deflection), which will not be less than 120 psf. The minimum total load (stress) will be the actual dead load (weight of concrete and deck) plus an additional 50 psf construction load. Bridge deck design incorporates the deflection and other design criteria required by the applicable governing jurisdictions. Typically, deflection under the dead load (Wd) will not exceed the design span (L) divided by 180 or 1/2”, whichever is less.

Physical design properties are calculated in accordance with the latest published edition of the American Iron and Steel Institute’s (AISI) “Specifications for the Design of Cold-Formed Steel.”
