Heavy‑Duty Drain Grates

Reset filters

Drains are the transport system to move unwanted water or waste liquids away from an area, so they don’t cause damage or flooding. They are built-in components to manage water flow and eliminate standing water, which can otherwise attract insects and accelerate the deterioration of nearby materials. In simplest terms, the drain is a hard‑working guardian that keeps surfaces dry, safe, and protected. Can the drain component that leads to a bigger drainage system have aesthetic appeal when cast in solid brass or aluminum? Simply put, yes.

Why Choose A&B Foundry Metal Drain Grates?

Drain grates are almost always in plain sight and underfoot. Our residential and commercial grade metal drain grates are metal-cast for added thickness, strength, and visual depth, giving you:

  • A more substantial, architectural look
  • Cleaner edges and a premium finish
  • Long-term durability in wet outdoor environments

Bottom line: you get a grate that complements the design and holds up to real-world use.

Round, Square & Channel Configurations 

Choose a look that matches the project’s design language:

  • Modern square patterns for clean lines and contemporary builds
  • Rounded or circular profiles for softer architectural styles
  • Slot, channel, and trench configurations to suit different drain layouts

Each grate is cast to maintain consistent geometry and spacing, supporting reliable water flow and a refined finished surface.

Popular Uses for Metal Drain Grates

A&B Foundry drain grates are commonly specified for:

  • Pool decks and perimeter drainage
  • Patios, courtyards, and walkways
  • Outdoor kitchens and entertainment spaces
  • Fountains, water walls, and spillway areas
  • Luxury residential and resort-style landscapes

Built for Long-Term Performance (and Easy Compatibility)

We cast drain grates in brass and aluminum, selected for strength, corrosion resistance, and a finish that holds up outdoors. All grates are made in the USA and built for long service life.

Many channel and round drop-in designs are made to fit common PVC’s, including NDS and similar systems, so they work well for new builds and upgrades.
