Heavy Duty vs. Light Duty Channel: Which Gauge Drain Do You Need?

The Real Difference

Both are fully sanitary. The difference is how it goes in, and what drives over it.

Heavy Duty channel is 11 gauge stainless, fully welded on site for maximum rigidity along a continuous run. Light Duty is 14 gauge and bolts together on site, so there's no field welding required. Both meet the same hygienic and compliance standard — the choice comes down to installation logistics and expected traffic.

When 316L Earns Its Cost

Four conditions where the upgrade is worth it.

Constant forklift and pallet-jack traffic crossing the run

Long continuous runs where rigidity matters most

New construction, where on-site welding is easy to schedule

Facilities that want zero bolted seams anywhere in the channel

Our Position

We spec both — and we'll tell you which your traffic actually needs.

Heavy Duty isn't automatically the better choice — it's the right choice when traffic and schedule call for it. Light Duty holds up fine in lighter-traffic rooms and installs faster with no welding crew on site. Tell us your traffic and timeline and we'll recommend honestly.
