Steel Price Forecast 2027: What Fabricators Should Plan For
Nobody can tell you where steel will be in December 2027, and you should be wary of anyone who sounds sure. What the data shows as of the August 2026 figures: the PPI for hot rolled bars, plates and structural shapes was up about 13% year over year, and steel mill products about 23%, with 50% Section 232 tariffs still in place and modest demand growth forecast for 2027. Plan for a range, not a number.
This post lays out what the data says, what's already priced in, three planning scenarios for 2027, and what a 10% move does to a typical 50-ton bid. Every figure here is dated. Prices move monthly, so check the linked sources for the current numbers before you use any of them in a bid.
Will steel prices go up or down in 2027?
There's no honest single answer. There are a few forces pushing each way, and the job is to decide which scenario you can live with.
What could push prices up:
- Tariffs on imported steel remain high, which supports domestic mill pricing.
- Global demand is forecast to grow faster in 2027 than in 2026 (see the worldsteel outlook below).
- Mills were still nudging spot prices up as of September 2026 (see below).
What could push prices down:
- Prices have already climbed a long way since early 2025, and high prices tend to pull in supply and slow buying.
- Any easing of tariffs or new trade deals would add import competition.
- A weaker construction or manufacturing economy would cut demand.
Here are three planning scenarios. These are not predictions. They're ranges to stress-test your bids against.
| 2027 scenario | Structural shapes and plate, change over 2027 | What would have to happen |
|---|---|---|
| Softer | down 5-15% | Tariff relief, weak demand, or mills giving back 2026 gains |
| Flat-ish | within about ±5% | Tariffs hold, demand grows slowly, mills hold pricing |
| Firmer | up 5-15% | New trade restrictions, strong demand, supply disruptions |
Scenario ranges are planning assumptions written in fall 2026, not a forecast. Use the current PPI and your mill and service center quotes.
If you're pricing a bid that will be built 6 to 12 months from now, ask which of these rows would hurt you, and price or write your terms so you can survive that row.
What does the data say about steel prices as of fall 2026?
Producer price indexes
The Bureau of Labor Statistics publishes producer price indexes that are easy to pull from FRED. Three are worth watching for structural work.
| Index (FRED series) | Aug 2025 | Aug 2026 | Change |
|---|---|---|---|
| Hot rolled bars, plates and structural shapes (WPU101704) | 275.6 | 312.5 | +13.4% |
| Steel mill products (WPU1017) | 308.8 | 381.2 | +23.4% |
| Fabricated structural metal products (WPU107) | 388.4 | 413.7 | +6.5% |
Index values, not seasonally adjusted, as of the August 2026 release (published September 10, 2026). Check FRED for the latest month.
A few things stand out:
- Shapes and plate (WPU101704) is the one to index to for structural work. It's what's closest to the beams, columns and plate on your BOM. It was 254.5 in January 2025, so it was up about 23% in 19 months by August 2026.
- Steel mill products (WPU1017) is broader and includes sheet and coil, which rose more than shapes over this stretch.
- Fabricated structural metal products (WPU107) rose more slowly. That's partly because fabricated prices include labor and overhead, not just steel. It may also mean some fabricators haven't fully passed rising material costs through to their prices yet.
The Associated General Contractors reported that steel mill product prices were up 16.9% year over year in June 2026, even as overall construction input prices dipped that month.
Mill spot prices
Mills publish spot prices that move weekly. Hot rolled coil is the most visible one, even though it's not what structural shops buy most. Steel Market Update reported that Nucor set its hot rolled coil consumer spot price at $1,190 per short ton on September 8, 2026, up $5 from the week before. HRC is a sentiment gauge for the whole market. For shapes and plate, your service center and mill quotes are the number that counts.
Demand outlook
The worldsteel Short Range Outlook from April 2026 forecast global steel demand growth of 0.3% in 2026 and 2.2% in 2027. For the United States it forecast 1.7% growth in 2026 and 2.0% in 2027, citing private investment and public infrastructure spending. That outlook was built on data from mid-March 2026, so check for a newer edition.
Modest demand growth isn't a price spike signal on its own. But it doesn't point to a collapse either.
How do tariffs and imports affect steel prices in 2027?
Tariffs are the biggest policy lever on US steel prices, and they can change with a single proclamation.
- June 2025: The White House raised Section 232 tariffs on steel and aluminum from 25% to 50%, effective June 4, 2025, with UK imports held at 25% at that time.
- April 2026: A new proclamation restructured the metals tariffs. Articles made entirely or almost entirely of steel pay a flat 50% on their full value. Derivative products pay 25% on full value, certain industrial and grid equipment pays 15% through 2027, and products with 15% or less metal content are excluded.
For fabricators, that means imported shapes and plate cost a lot more than they did two years ago, domestic mills have room to price higher, and imported fabricated products face their own tariffs. Our steel tariffs guide for fabricators covers what this means for sourcing.
What's "priced in" right now is the tariff level as of the latest proclamation. A cut or a new trade deal would be a downside risk to price. A new increase or broader coverage would be an upside risk. Watch the news, and don't write 12-month price guarantees on the assumption that today's tariff rate holds.
What does a 10% steel price move do to a 50-ton bid?
Take a 50-ton structural package. That's 100,000 lb. Use example numbers: material at $0.60/lb, and a total installed bid of $1.80/lb.
| Line | Value |
|---|---|
| Material | 100,000 lb × $0.60 = $60,000 |
| Total bid (fabricated and erected) | 100,000 lb × $1.80 = $180,000 |
| Net profit at a 10% net margin | $18,000 |
| 10% material price move | $6,000 |
| Share of total bid | 3.3% |
| Share of net profit | 33% |
A 10% material move looks small against the bid total. It's a third of your profit. A 15% move takes half. Plug your own numbers into the steel weight and cost calculator to see your exposure on the next bid.
For per-ton context by building type, see structural steel cost per ton, and for how material fits into a per-pound price, see fabricated steel cost per pound.
When prices move weekly, the speed of re-pricing matters. Set your material rate once in SteelFlo's Price This and re-run the estimate when your quote changes, without redoing the takeoff. The first 3 takeoffs are free.
How can fabricators protect bids from steel price swings?
You can't control the market. You can control how long your price is good for and who carries the risk.
Short validity windows
Put a firm expiration on every bid. 30 days is common, and 15 or fewer when the market is moving fast. After that, the material portion gets re-quoted. If a GC sits on your number for three months, that's their choice and their risk.
Escalation clauses
An escalation clause lets the material price adjust if a published index moves past a set threshold between bid and purchase. A common setup:
- Name the index. WPU101704 (hot rolled bars, plates and structural shapes) is a good fit for structural work.
- Set a base month, usually the bid month.
- Set a trigger, for example a move of more than 5% either way.
- Apply the change only to the material portion, not labor or margin.
- Make it two-way, so the owner gets a credit if prices fall. Clauses that only go up are harder to get signed.
Our steel price escalation clause guide has sample language and the details that make a clause enforceable. Have your attorney review anything you put in a contract.
Lock material early
If you win, buy or reserve material as soon as the contract allows. Mill and service center quotes have their own validity windows, often short. Some shops ask for a material deposit on large jobs so they can buy right away. Check steel lead times too, since a long lead can force you to buy before shop drawings are approved.
Separate material from labor in your bid
If your bid shows material as its own line, it's much easier to adjust it later, explain the change to a GC, or apply an escalation clause. A lump sum with everything blended hides your exposure, even from you.
Bottom line
As of fall 2026, steel prices were well above early-2025 levels, tariffs were high, and forecasters saw modest demand growth for 2027. That's an argument for planning ranges, short bid windows and escalation terms, not for betting on one number. When your mill quote changes, SteelFlo's Price This lets you update the material rate and re-price the estimate from the same takeoff.
Frequently Asked Questions
Will steel prices go down in 2027?
They might, but nobody knows. A cut in tariffs or weaker demand could push prices down, while steady tariffs and growing demand could hold them up. Plan for a range, and check the current PPI and your mill quotes before each bid.
What is the best index for steel escalation clauses?
For structural work, the BLS PPI for hot rolled bars, plates and structural shapes (FRED series WPU101704) is a common choice. It tracks the products closest to a structural BOM. Name the index, base month, and trigger threshold in the contract.
How much have steel prices gone up?
As of the August 2026 PPI data, hot rolled bars, plates and structural shapes were up about 13% from a year earlier, and steel mill products about 23%. Fabricated structural metal products rose about 6.5%. Check FRED for the latest month, since these change monthly.
What are the current steel tariffs?
As of the April 2026 proclamation, articles made entirely or almost entirely of steel pay a flat 50% Section 232 tariff on their full value, and derivative products pay 25%. Trade policy changes often, so check the latest White House or CBP guidance.
How long should a steel bid be valid?
30 days is a common validity window, and 15 days or fewer makes sense when prices are moving quickly. After the window, re-quote the material portion. Longer validity calls for an escalation clause or a higher contingency.
