Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
How it's built
Fabricated steel plate rose 0.8% over the last 12 months, but all of its main inputs rose faster: hot rolled steel bars, plates, and structural shapes +15.0%. That cost pressure may still pass through to prices.
From Jan 2017 to Aug 2026 the index went from 214.2 to 380.1, a change of +77.4%.
Highest reading in that period: 380.1 in Aug 2026. Lowest: 214.2 in Jan 2017.
Largest one-month rise: +12.7% in Aug 2024. Largest one-month fall: -1.5% in Sep 2019.
For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 12 of the last 36 months.
Use it in a contract
Draft clause citing this series
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Fabricated Steel Plate (BLS series WPU1076), published by BLS.
Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value.
Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value.
Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement.
[Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Covers cut and shaped steel plate as a manufactured product, distinct from raw hot-rolled steel, useful when the contract buys ready-to-weld plate rather than coil.
Divide the current value of BLS series WPU101704 (Hot Rolled Steel Bars, Plates, and Structural Shapes) by its value at contract signing, then apply that ratio to the structural steel part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Let Escalake run this clause for you
Escalake tracks US PPI — Fabricated Steel Plate, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
