Warranty: a. The manufacturer shall warrant all assembly work performed under these specifications to be free of defects for a period of one year when installed by a trained SES installer. b. Any materials found to be defective within one year shall be replaced at no cost to the owner. c. Acts of vandalism or abuse shall render the conditions of this warranty null and void. d. Any exposed mill finished aluminum surface that may become discolored, which is caused when mill finish aluminum gets damp for water either during normal freighting or site installation resulting in oxidation called Mill Stain, this is a natural phenomenon and will ultimately fad. Bleacher manufacturer will not be responsible for this type of discoloration due to oxidation or Mill Stain when dealing with mill finishaluminum.
