Both keep walkways safe and drained, but they look and behave differently.
Heel-safe gratings
Narrow, closely spaced openings across the full grating. They suit busy entrances, plazas and malls, where people walk across the channel all day. See heel-safe gratings.
Slot drains
Only a thin line shows on the surface. They suit lobbies, terraces, pool decks and premium hardscape where the drain should almost disappear. See stainless steel slot drains.

Neither one is right. Use a heavy-duty grating.

Materials and finish
Use SS 304 indoors in dry areas and SS 316 for pools, coastal sites and external areas. Brushed finish hides scratches; mirror finish suits premium lobbies.
Matching the grating to the channel
Send us the channel width and length. Heel-safe gratings and slot drains can be made to custom sizes to fit existing channels.
Accessibility
Narrow openings are safer not only for heels but also for wheelchairs, prams and trolleys, which is why heel-safe gratings are common at public entrances.
Frequently asked questions
Which is better for a pool deck?
Both work. Slot drains give a cleaner look; heel-safe gratings are easier to lift and clean.
Are they available in stainless steel 316?
Yes, SS 316 is recommended for pools, external and coastal areas.
Can heel-safe gratings replace my existing gratings?
Often, yes. Send us the channel width and grating length and we will match them.
Do slot drains block easily?
Not with normal cleaning. Rinse the slot and clear the access points regularly, especially near landscaping.
