Fully welded vs. bolt-together: two ways the same drain goes in.

Same channel, same standard — the difference is what happens on install day.

The Real Difference

The tradeoff is your install day, not your inspection day.

Fully Welded installation joins every section on site for a continuous, seamless run — the highest hygiene standard, but it requires a welding crew on site. Bolt Together assembles with hardware instead, so there's no field welding required and installation moves faster.

Grade Comparison

Where the difference actually shows up.

Fully WeldedContinuous seamless run, requires on-site welding
Bolt TogetherBolts together on site, no field welding required
Maximum Hygiene PriorityFully Welded closes every seam
Fast Install / No Welding CrewBolt Together is the practical choice
When 316L Earns Its Cost

Four conditions where the upgrade is worth it.

1

No welding crew available or permitted on site

2

Retrofit with a tight shutdown window

3

Facility rules restrict hot work

4

Sections need to be field-adjustable during install

Our Position

Both meet the same hygienic standard — the difference is your install day.

We don't push Fully Welded on every job. If hot work isn't practical on your site or your shutdown window is tight, Bolt Together gets you the same drain without a welding crew. Tell us your site constraints and we'll recommend honestly.
