Grenfell Tower fire inquiry says U.S. company Arconic "deliberately concealed" dangers of building materials

London - The public inquiry into the deadly 2017 fire that engulfed Grenfell Tower, a high-rise public housing apartment building in central London, published its final report Wednesday on the disaster that killed 72 people. The blaze — London's deadliest since World War II — was blamed on a litany of failures, from shoddy construction and materials to poor local management and inadequate fire safety standards.

Among the parties found to have played a role in the tragedy by the inquiry is the American company Arconic, which made and sold the building's exterior cladding through a French subsidiary.

The report's authors said the Pittsburgh-based company "deliberately concealed from the market the true extent of the danger of using" the materials that were added to Grenfell Tower during a renovation, "particularly on high-rise buildings."
