**Economical mill finish tread planking and risers have been known to discolor stain and/or fade as a result of unavoidable condensation that occurs during packaging, transporting, and storage, preceding and/or during installation.  Markstaar will not be responsible for this occurrence.  A clear anodized finish may be purchased to avoid potential staining if selected as an upgrade finish at an additional cost.
