What the mill certificate tells you before the first cut
A mill certificate read at the bench before the saw: heat number, ASTM grade, yield and tensile, and what the paper does not prove about the plate under it.
Bench notes from a New England steel shop
Steel cut in Greenfield, set across New England
Structural steel fabrication and erection: beams, columns, decking, stairs and ornamental ironwork, cut in our Greenfield shop and set by our own crews across New England.
latest note · What the mill certificate tells you before the first cut
What the cut edge says about the pass that made it
Top edge rounding, dross on the bottom, a few degrees of bevel and the kerf: what a plasma-cut edge records about the pass that made it, read at the bench.
Squaring a bay by the tape: what the diagonals said
Two pulls of a 100 ft tape across one bay, the two numbers written side by side, and the difference that decides whether the deck goes on today.
The work
-
Structural erection
Beams, columns, metal decking, precast and shear studs set by our own ironworkers, from a school gym to a hospital wing.
-
Shop fabrication
Cut, coped, welded and painted in Greenfield: plate, angle, channel and bar to the drawing, with mill certs on file.
-
Ornamental & misc metal
Stairs, rails, gates and grates: the small metal that finishes a building, drawn, built and set by the same crew.
- Mill certificates kept on file
- Every weld checked by a second pair of eyes
- Own crews on the steel, nothing subbed
- Each note says what it did not test
The protocol
How a bench note is checked
- 01The check is announced before the result: what we measured, on which job, against which spec.
- 02Values are given as read: the number the tape, the gauge or the mill certificate returned.
- 03Every note ends with what it does not cover: the bench says what it did not test.
The rest of the bench
-
The fit-up check that happens before the weld goes in
Root opening, bevel, root face and hi-lo, read with a taper gauge, a protractor and a caliper on one groove joint, with the numbers as they came off the bench.

A school gym frame in six working days: the sequence
Six working days, one crane, and a southern New Hampshire school gym: the shake-out, the pick sequence, and the check values written on the back of a plan.

When the anchor bolts do not line up: what gets measured first

Coping beams so they bolt up in the air, not on the phone
A cope gets cut and checked on the bench: cut dimensions, the clearance to the supporting member, the gage line on the angle, and what the tape cannot prove.

Shop weld or field weld: what the drawing actually says
Bench check on a weld callout: where the symbol puts the weld, what the field flag changes, and what the crew does when the drawing and habit disagree.

Steel notes
What a New England steel crew learns about the trade, the codes and the weather
From other shops
Notes kept by other shops that follow trades, tools and the work itself, each read before it ran here.
For the metalwork side of the trade, the bench reads a forge that keeps historic ironwork alive, from hand-forged rails to reproduction hardware.
On the bench itself, a catalog of the hand tools that dress bench work is worth the read before the next fit-up.
And for the yard side, notes on how shops store and handle heavy stock keep our own plate racks honest.
