The open metal grid decking is an excellent choice to increase the load limit on existing trusses and flat beam bridges. Steel Beam Bridges Our weathering steel beam bridge uses a metal grid deck with A-588 weathering steel which requires no painting.
As bridge decks. Grating can also come in 4 feet ( cm) or 2 feet (61 cm) x 8 feet ( cm) panels which are often used for decks on bridges, footbridges and catwalks. Other panel sizes may also be available. Grating can be made of different materials like steel, aluminum, fiberglass. Fiberglass grating is also known as FRP grating.

Chicago has 25 open metal grating bridges without bicycle friendly lanes. Many riders feel unstable and wobbly while crossing the bridges, especially when wet. The Chicago Department of Transportation (CDOT) has installed anti-slip metal deck plates over three open grating bridges over the past two years.
They can stand up with loads from heavy traffic such as automobiles, trucks and other vehicles. Steel and aluminum are two economical materials to manufacture deck gratings. Steel gratings are often galvanized or PVC coated to face corrosions. Metal open grating permits passage of rains and snows that a solid surface will not allow.

The resulting product is an exceptionally durable heavy duty grating with superior stiffness and lateral stability. Bridge Decking is often the preferred heavy duty grating for concentrated or stress applications subject to impact and repetitive loads. Popular applications include bridge floors, highway inlets, and airport trench drain covers.

It replaced an open steel grating deck that had lasted 50 years, but provided less traction for vehicles in wet weather. Choices for the lift span deck type are limited because the deck’s weight needs to be balanced by the weight of two million pound concrete counterweights, and supported by the bridge structure.
Stainless steel material offers high resistance to corrosion, extreme temperature resistance, strength and lasting durability. Stainless steel grating is perfect for open areas to allow the passage of light, air, heat and sound between floor levels.
