What “forklift rated” actually means.

Every catalog says “heavy duty.” Load class is the part that actually tells you it will hold.

Beyond “Heavy Duty”

Thickness alone doesn't rate a drain.

"Heavy duty" is a marketing term. Load class is an engineering one — it describes how a cover, grate, or curb performs under repeated point loading from forklifts and pallet jacks. A thick cover with the wrong support spacing can still fail faster than a properly designed thinner one.

What Determines the Rating

Four factors, not one.

1

Material gauge and thickness — the starting point, but not the whole answer

2

Support bracket spacing beneath the cover or grate

3

Cover and grate design — slot width, rib pattern, and weld points

4

Anchoring into the slab, so the whole assembly moves as one unit under load

The Honest Version

Not every room needs it.

Forklift-rated hardware costs more, and a foot-traffic-only room may not need the same load class as a loading dock. We'd rather spec the room correctly than sell you a rating you don't need.
