Commonly confused with
CU 42240 — Structural steel erection services
Fabricating makes the parts — girders, joists, prefabricated structural sections, welded reinforcing mesh — in a workshop. Erection is putting them up on site: structural steel erection, reinforcing steel erection, silo and tank erection, welding on construction projects. Same steel, two different units, and ACC rates them differently.
$1.48 against $2.25: $0.77 apart, CU 42240 dearer , $1,206 a year at the ceiling.
CU 27110 — Iron smelting and steel manufacturing
Smelting and steel manufacturing makes the steel itself — bar, flat-rolled product, ferro-alloy, direct reduction iron. Fabricating starts with steel that already exists and cuts, welds and assembles it into structural parts.
$1.48 against $0.9: $0.58 apart, CU 27410 dearer , $909 a year at the ceiling.
CU 27120 — Iron and steel casting
Casting pours molten metal into moulds — iron and steel castings, die-castings, moulded cast iron pipe. Fabricating shapes and joins steel that is already solid.
$1.48 against $0.9: $0.58 apart, CU 27410 dearer , $909 a year at the ceiling.
CU 27121 — Iron and steel forging
Forging shapes metal under force — forged chain, forged pipe and tube fittings, forged valve parts. Fabricating cuts and welds rolled sections into structures rather than forming metal by force.

BIC codes that map here
ACC assessors work from Business Industry Classification codes. These are the codes that land on CU 27410:
| C222110 | Fabricated structural steel mfg – ready made parts for structures |
|---|---|
| C222120 | Girder mfg – prefabricated steel |
| C222130 | Joist, prefabricated steel mfg |
| C222140 | Reinforcing steel rod, processed, mfg |
| C222150 | Roof truss mfg – prefabricated steel |
| C222160 | Scaffolding mfg – prefabricated steel |
Changing a BIC code takes two agencies, not one.
