Stair Treads are produced by steel gratings with surface to be hot
galvanized or electrogalvanized. They are widely used as industrial
platforms, aisle floors, railway bridge sideways, parking lots
(Steel gratings consist of a series of flat bars cross jointed by
welding at various intervals with cross bars to form some kind of
steel products with square lattice among them.)

treads ,its surface treatment is hot dip galvanized,the price is
the lowest but value is better according to meterial cost &
application .It canbe used in indoor & outdoor ;2aluminum stair
treads ,the weight is lighter than mild caron stair treads.Its
apperance is better , but the price is expensive than mild carbon
.aluminum stair treads is more adjust indoor .3stainless stair
treads ,the surface is so pretty ,it is anti -acid &anti
-alkali corrosion capacity .it can be used outdoors.
