Galvanized Steel Stair Treads Uses

Galvanized Steel Stair Tread is the most widely used for their strength and ease of installation and are universally used in most industrial and commercial applications. Riveted steel stair treads have a greater load carrying capacity for the same span and depth of bearing bar and greater walking comfort. Both can be ordered with a serrated surface for additional safety.
Food processing plants, maintenance areas, worker platforms on marine and oil rigs are just a few of the areas that commonly employ the use of stair treads to increase safety.
