Key figures
From Jan 2024 to Aug 2026 the index went from 281.8 to 312.5, a change of +10.9%.
Highest reading in that period: 312.5 in Aug 2026. Lowest: 250.3 in Feb 2025.
Largest one-month rise: +5.4% in May 2025. Largest one-month fall: -3.6% in Dec 2024.
For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 12 of the last 20 months.

What this means for your clause
Structural steel fabrication and building frame contracts escalate against this series since beams and plate stock ship hot rolled. A contract that cites the cold rolled series instead would track a finishing cost the structural buyer never pays for.
Draft a clause
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 — Hot Rolled Steel Bars, Plates, and Structural Shapes (BLS series WPU101704), 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.]
Compare the current value of BLS series WPU101704 (Hot Rolled Steel Bars, Plates, and Structural Shapes) to its value at contract signing, turn that into a ratio, and apply the ratio to the structural steel-affected line items. A usable clause also names an averaging window, a publication-lag rule, and a cap.
