Our Work — Melco FireStopping

What You're Looking At

Every photo above is a real condition from an active job -- not a stock diagram. Here's what each type of work is actually doing.

Identify

Walk the job and find every penetration -- pipe, conduit, cable, duct -- through a rated wall or floor.

Match the System

Pick the UL-tested system for that exact penetration type and wall or floor assembly.

Seal

Install firestop caulking, spray fireproofing, or a tested collar/wrap per the system's listing.

Tag & Pass

Label the install and leave it ready for inspection -- code-compliant, not just "finished-looking."

Spray-applied fireproofing

The thick, textured coating you see on structural columns and ceiling decks. It protects the steel itself so it holds its strength longer in a fire -- a different job from sealing a penetration, and often needed on the same project.

Pipe and conduit penetration sealing

Anywhere a pipe, conduit run, or cable bundle passes through a fire-rated wall or floor, that opening has to be sealed with a tested system -- otherwise the wall's rating doesn't mean much. The red firestop material you see at the base of grouped pipes in several photos is exactly this.

Rated wall signage

"1 Hr Rated Fire Wall" and similar stenciled signs mark a wall's fire-resistance rating so every trade on the job knows it has to be protected -- a reminder that any new penetration cut into it needs to come back to a firestopping crew.

Top-of-wall and ductwork conditions

Where a wall meets the deck above, or where ductwork passes through it, needs its own tested detail -- a different system than a simple round pipe penetration.

Real jobs. Real fire-rated seals.
