Mebac® Surfaced Steel Z-Treads is a staircase system that uses a single piece of 3/16” carbon steel plate to form 6”-7” risers, treads and stringer attachment brackets with no welds. Z-Treads provide a fast, economical way to design and construct a steel staircase with built-in, long-term slip-resistance that is durable, low maintenance and strong, with a superior coefficient of friction under wet or dry conditions. The simplicity and versatility of Z-Treads allows fast, easy field erection, saving time and money.
