The choice of floor and deck construction is an important part of your bridge design. U.S. Bridge helps you make that decision with a range of durable, sustainable deck systems, each matched to your span, traffic, dead-load targets and environment. From cast concrete to lightweight steel grid, the deck is engineered as part of the complete structure.

Deck & Floor Options
U.S. Bridge supplies and engineers five proven deck systems. The right choice depends on span, traffic, weight limits and setting.
Concrete Deck Slab
The most common deck: a 7–9 in. reinforced structural slab cast on removable forms or permanent stay-in-place (SIP) metal forms.
Corrugated Steel Bridge Plank
Roll-formed 3 in. or 4-1/4 in. corrugated steel planking, cut to bridge width and skew, for beam or truss bridges.
Nail-Laminated Timber Floor
A rustic treated-timber deck for trails and forest roads. U.S. Bridge supplies the lumber, nails and attachment clips.
Open Grid Steel Deck
An open steel grid that reduces dead load and sheds water and snow, ideal for movable or weight-sensitive spans.
Precast Concrete Plank
Factory-cast concrete planks for fast, consistent installation with minimal field forming.

Questions & Answers
Bridge Flooring & Deck Systems FAQ
Design & Selection
U.S. Bridge offers five deck systems: concrete deck slab, corrugated steel bridge plank, nail-laminated timber floor, open grid steel deck, and precast concrete plank.
The best deck depends on span, traffic and loading, weight limits, setting and budget. Concrete suits most highway spans, steel plank and open grid reduce dead load, timber suits rustic trails, and precast speeds installation. U.S. Bridge engineers the deck as part of the complete structure.
Specifications & Supply
A concrete deck slab is typically designed between 7 and 9 inches thick and reinforced with two layers of steel reinforcing bars, often epoxy-coated for corrosion protection.
A stay-in-place form is a permanent light-gauge metal form attached to the steel superstructure that supports the concrete deck pour and remains as part of the structure, reducing field forming.
Yes. U.S. Bridge supplies the deck materials for each system, including steel planking, SIP forms, and the lumber, nails and clips for timber decks.
