Zurn Z537 – 16" Square Top Heavy-Duty Parking Deck Drain with Support Flange

A rugged, square-top deck drain designed for high runoff on exposed parking structures—combining a gasketed support flange, slotted heavy-duty grate, and a Dura-Coated cast-iron body.

The Zurn Z537 is purpose-built for rooftop parking decks, ramps, and exposed garage levels. In technical terms, it’s a Dura-Coated cast-iron drain body with a bottom outlet and a heavy-duty gasketed support flange—in plain English, it anchors solidly to the slab, ties cleanly into the deck’s waterproofing interface, and uses a heavy-duty slotted grate to admit stormwater while standing up to vehicle traffic.

Key Features

  • 16" square top provides a large collection area at the deck surface.
  • Dura-Coated cast-iron body for long-term durability in harsh, exposed conditions.
  • Heavy-duty slotted grate engineered for vehicular traffic and efficient inflow.
  • Gasketed drain support flange to anchor the drain and interface with deck waterproofing.
  • Bottom outlet for straightforward connection to vertical drainage piping.

Where Z537 Excels

Use the Z537 on top decks, ramps, plazas, and exposed garage levels where drains must resist impact, traffic, and weather. The square top complements linear slope patterns, while the heavy-duty grate resists deformation and helps reduce trip hazards near pedestrian paths.

Case Study: Downtown Garage Top-Deck Rebuild

A city garage experienced ponding and membrane leaks on its top deck. Engineers replaced undersized drains with Zurn Z537 units. The 16" square top improved surface capture, and the gasketed support flange simplified the waterproofing interface. After one storm season, maintenance logs showed faster drainage, fewer freeze-thaw joints issues, and no grate-related trip incidents.

Frequently Asked Questions

What does the support flange do?
The heavy-duty gasketed support flange anchors the drain to the slab and provides a robust interface for the deck’s waterproofing system, helping prevent leaks at the penetration.
Is the grate traffic-rated?
Yes—Z537 uses a heavy-duty slotted grate designed for vehicular traffic typical of exposed parking decks. Always confirm load criteria in project specs.
What outlet sizes are available?
Multiple outlet sizes and connection types are available (e.g., no-hub, inside caulk/gasket). Verify the required size and type on the Zurn submittal for your job.
