Zurn Z536 – 15" Parking Deck Drain with Support Flange

A heavy-duty deck drain built for exposed garages, ramps, and plazas—combining a gasketed support flange with a durable, slotted grate and Dura-Coated cast-iron body.

The Zurn Z536 is a 15-inch diameter, heavy-duty parking deck drain with a gasketed support flange and slotted grate. In practice, that means secure anchorage to the slab, clean tie-in to waterproofing, and dependable inflow under vehicle traffic—ideal for top decks and ramps that see high runoff and harsh weather.

Key Features

  • 15" diameter, heavy-duty construction for exposed parking structures.
  • Gasketed support flange anchors the drain and interfaces with deck waterproofing.
  • Dura-Coated cast-iron body for long-term durability.
  • Heavy-duty slotted grate supports vehicular areas and admits surface water efficiently.
  • Bottom outlet simplifies connection to vertical drainage piping.

Where Z536 Excels

Use the Z536 on top decks, ramps, plazas, and exposed garage levels where drains must withstand traffic, impact, and weather. The large top collects runoff at the surface while the support flange helps create a robust, watertight interface with deck membranes.

Case Study: Airport Garage Top-Deck Retrofit

An airport’s top-deck garage had recurring ponding near expansion joints and drain locations. Engineers replaced undersized drains with Zurn Z536 units using No-Hub outlets and underdeck clamps. The 15" tops improved surface capture, while the support flange simplified the membrane interface. After a full storm season, maintenance logs showed faster drainage, fewer freeze-thaw issues at joints, and zero grate-related trip incidents.
