AIL has long identified environmental stewardship and commitment to sustainability as part of our Company’s strategic plan and our vision for the future. As we have in the past, we will continue to actively examine strategies to advance that vision and our commitment to leadership for our industry.

Recycled and recyclable steel

AIL products use a high degree of steel, the world’s most-recycled material. Given the increased awareness of “green” construction, steel is the material of choice because of its major recycled content and recyclability attributes. Steel products use less energy to manufacture, ship and install than their concrete counterparts.

Naturally-weathering steel

Big R Prefabricated Steel Bridges are made from recycled steel and are available in naturally-weathering or custom-painted finish options. Weathering steels provide a number of environmental benefits.

	Minimal site impact Efficient bridge and culvert designs install quickly and easily with minimal site impact.
	Open flow designs Wide-span capability prevents blockages and flooding associated with concrete box designs.
	Low-maintenance Virtually no maintenance compared to concrete, reduces future costs, negative site impact.
	Salt and soft water Use of corrosion/abrasion-resistant Dur•A•Span Aluminum protects salt and soft water habitat.
	Fish passages Fish baffle inserts and open-bottomed culverts with integrated footings facilitate fish movement.
	Wildlife crossings Custom-designed underpass and overpass crossings help protect species, preserve habitat, and increase safety.
	Culvert relines Help salvage older structures and avoid the cost, safety and environmental issues of full replacement.
