Below is a list of Aluminum Beams manufacturers from Hamden, Connecticut. Aluminum beams are large, oblong pieces of metal, specifically constructed from aluminum alloys, that are typically used to horizontally support components of building construction. Aluminum is used in beam fabrication as an alternative to steel, which is stronger but much heavier, and wood, which is lighter but much weaker. Aluminum beams are essential in the construction, engineering and architectural industries as parts and shapes necessary to the internal and external construction of buildings.
