Section 2603-A. Letting of certain contracts involving steel products

1.
  Notwithstanding any other provision of law, all public authorities shall
  award contracts involving steel products as follows:
    a.  All  purchase  contracts  for  supplies,  material  or   equipment
  involving  an  estimated expenditure in excess of fifty thousand dollars
  shall require with respect to materials, supplies and equipment made of,
  fabricated  from,  or  containing  steel  components,  that  such  steel
  components  be  produced  or  made  in  whole or substantial part in the
  United States, its territories or possessions. The  provisions  of  this
  paragraph  shall  not  apply  to motor vehicles and automobile equipment
  assembled in Canada in conformity with the United States-Canadian  trade
  agreements  known  as the "Automotive Products Trade Act of 1965" or any
  amendments thereto.
    b. All contracts in excess of one hundred  thousand  dollars  for  the
  construction,   reconstruction,   alteration,   repair,  maintenance  or
  improvement of public works shall require  that  all  structural  steel,
  reinforcing  steel  or other major steel items to be incorporated in the
  work of the contract shall be produced or made in whole  or  substantial
  part in the United States, its territories or possessions.
    2.  The  provisions  of  this section shall not apply if the governing
  board or body of such public authority, in  its  discretion,  determines
  that  such  provisions  would  result in unreasonable costs or that such
  steel products or steel components cannot be produced  or  made  in  the
  United  States  in  sufficient and reasonably available quantities or of
  satisfactory quality or design.
