CSI 05 50 00
Miscellaneous Metals
Miscellaneous metals is the coordination-heavy Division 05 50 00 scope GCs struggle to award: embeds, lintels, bollards, grating, ladders, platforms, and supports. TMG self-performs it and delivers on the erection curve across SC, NC, and GA, to ASTM, AWS D1.1, and IBC/OSHA.
The scope nobody wants to own
What are miscellaneous metals, and why are they hard to award?
Miscellaneous metals is the collection of steel items outside the primary frame: embed plates, lintels and shelf angles, pipe bollards, bar grating, fixed ladders and cages, platforms, catwalks, mezzanines, and the brackets and supports that tie other trades to the structure. Each item is small. Together they are a coordination puzzle that touches concrete, MEP, envelope, and equipment.
That is exactly why the package is hard to award. It is hundreds of line items, each tied to another trade or a specific embed location, with no headline tonnage to make it attractive. Fabricators chasing easy structural work often leave it, and it lands late in the schedule as an orphan scope. TMG self-performs miscellaneous metals as part of a single-source Division 05 award, so embeds, supports, and access steel arrive coordinated to the frame instead of scrambled in after it.
Scope of work
Miscellaneous metals we fabricate and install
Self-performed and sequenced to the erection curve, not bolted on as an afterthought.
- Embed plates and weld plates
- Anchor bolt assemblies
- Bearing and leveling plates
- Lintels and shelf angles
- Miscellaneous supports and brackets
- Framing at penetrations
- Pipe bollards
- Bar grating and trench covers
- Fixed ladders, cages, and rungs
- Platforms and catwalks
- Mezzanines
- Equipment and dunnage supports
On the erection curve
How single-source keeps misc metals on schedule
The problem with misc metals is timing, not fabrication. Embeds have to be set before the pour; supports and platforms have to land as the frame rises. When a separate fabricator owns the scope, that timing depends on a handoff nobody controls. TMG removes the handoff.
| Item | Sits on | Single-source advantage |
|---|---|---|
| Embeds & plates | Concrete critical path | Sequenced to the pour, not a separate shop queue |
| Lintels & angles | Masonry / envelope | Delivered as openings are framed |
| Platforms & catwalks | Erection curve | Installed with the frame by the same crew |
| Ladders & cages | Life-safety / turnover | Built to OSHA and punched in one QA chain |
Standards: ASTM material specs, AWS D1.1 welding, and IBC plus OSHA for installed guarding, ladders, and access steel. One accountable party runs it all from submittal to turnover.

Frequently asked
What counts as miscellaneous metals in CSI 05 50 00?
Miscellaneous metals, CSI Division 05 50 00, covers the many small steel items outside the primary frame: embeds and embed plates, lintels and shelf angles, pipe bollards, bar grating, fixed ladders and cages, platforms, catwalks, mezzanines, and assorted supports and brackets. Individually minor, collectively they touch nearly every trade on the job.
Why do GCs struggle to award the misc metals package?
Misc metals is coordination-heavy and low-glamour: hundreds of line items scattered across drawings, each tied to another trade or embed location. Many fabricators cherry-pick the easy structural tonnage and leave it. TMG self-performs it and delivers on the erection curve, so it stops being the scope nobody wants to own.
Does TMG coordinate embeds with the concrete schedule?
Yes. Embeds and embed plates have to be set before the pour, so they sit on the concrete critical path, not the steel one. Because TMG fabricates and erects as a single source, we sequence embed delivery to the slab and foundation schedule rather than to a separate fabricator queue.
What standards govern TMG miscellaneous metals?
Fabrication uses ASTM material specifications, welding follows AWS D1.1, and installed items meet the applicable IBC and OSHA requirements, including OSHA fixed-ladder and guarding rules. TMG is an AISC Certified Fabricator with AWS D1.1 certified welders.
Can misc metals ship with our structural steel package?
Yes, and that is the point of single-source. Bundling misc metals with structural steel and stairs means one submittal chain, one delivery schedule, and one crew coordinating embeds, supports, and platforms into the frame as it goes up.
