How Is Steel Priced? What Goes Into Your Quote

November 1, 2026 in Steel Supply

Key Takeaways

CWT means 100 pounds. Divide a CWT price by 100 for the price per pound, or multiply by 20 for the price per 2,000-pound ton.
Weight drives the price. Wide flange names give the weight per foot, and steel plate weighs about 40.8 pounds per square foot for each inch of thickness.
Extras sit on top of the base price, covering things like length, grade, cutting, testing, and order size.
Processing and freight can be separate line items, so compare them with what the same work and trucking cost you.
Quotes expire because prices move. Check the expiration date, and look at escalation clauses on long, fixed-price jobs.

Two quotes for the same material list can look very different. Some of the gap comes from the market, but a lot of it comes down to how each quote is built: the weight, the base price, the extras, the processing, and the freight.

Steel is usually priced by weight, most often per hundredweight, written CWT, which means per 100 pounds. The material cost is the weight in hundredweights times the CWT price. Extras for things like grade, length, or small quantities get added on top, along with processing, such as cutting, and delivery.

Knowing how those pieces fit together makes it easier to budget a job, compare suppliers, and see what changed when a requote comes back higher.

What Does CWT Mean in Steel Pricing?

CWT stands for hundredweight. In the U.S., a hundredweight is 100 pounds. The British hundredweight is 112 pounds, which only matters when you’re reading an overseas price.

Converting between units is simple math:

Price per pound = CWT price ÷ 100. At $50.00 per CWT, steel costs $0.50 per pound.
Price per ton = CWT price × 20. At $50.00 per CWT, that’s $1,000 per short ton of 2,000 pounds.
Weight in CWT = pounds ÷ 100. A 3,264-pound plate is 32.64 CWT.

The prices in these examples are round numbers for illustration, not current market prices.

You’ll also run into tons. In U.S. steel pricing, a ton usually means a short ton, also called a net ton, of 2,000 pounds. A metric tonne is about 2,204.6 pounds, and a long or gross ton, a unit used mostly for scrap, is 2,240 pounds.

CWT pricing shows up well beyond mill price sheets. Some state transportation departments, including North Carolina’s and Ohio’s, use steel price indexes stated in dollars per CWT to adjust payments on highway contracts.

How to Figure Steel Weight and Price per Pound

Because price follows weight, the first step is knowing what your material weighs.

Wide Flange Beams

Wide flange beam names include the weight per foot. A W12x26 weighs 26 pounds per foot, so ten 40-foot pieces weigh 10 × 40 × 26 = 10,400 pounds, or 104 CWT. At an example price of $50.00 per CWT, that’s $5,200 in base material before extras, processing, or freight. Our guide to structural steel sizes and weight explains how shape names work.

Plate

Steel plate weighs about 40.8 pounds per square foot for each inch of thickness. A 1/2-inch plate measuring 8 by 20 feet covers 160 square feet at 20.4 pounds per square foot, for a total of 3,264 pounds. Our steel weight formulas page covers rounds, squares, flats, plate, and tubing.

Converting a Per-Foot Price

If one supplier quotes per foot and another quotes per CWT, convert one to the other: price per foot ÷ pounds per foot × 100 = price per CWT. A W8x18 quoted at $14.40 per foot works out to $0.80 per pound, or $80.00 per CWT. Once every quote is in the same unit, you can compare them line by line.

What Sets the Base Price of Steel?

The base price per CWT moves with the market. Supply and demand matter most, along with the cost of raw materials like scrap and iron ore and the country where the steel was made. Trade policy plays a part too: tariffs on imported steel raise the cost of foreign material and shift more demand to domestic mills. Prices can change from day to day, though daily moves are usually small.

The base price also varies by product. Mill price lists can set a separate base price for each shape size, and specialized grades cost more per CWT than common structural grades. Some products have their own cost drivers as well, and our breakdown of commercial metal decking cost walks through the factors for deck.

Extras: What Gets Added to the Base Price

Mills publish price lists with a base price and a list of extras, which are charges added for anything outside the standard product. One published domestic beam price list, for example, includes:

Length extras for lengths outside the mill’s standard range
Grade extras for steels like A588 weathering steel
Cutting extras for cutting from stock lengths, with a stated cutting tolerance
Testing extras for tests like Charpy impact testing
A minimum order quantity, stated in tons

That minimum order is one reason fabricators buy from service centers. A service center buys in mill quantities, holds the inventory, and sells the quantities a job needs, often with processing and delivery. AISC describes service centers as a fabricator’s extended inventory warehouse, and that convenience is part of what you pay for in service center pricing. At Intsel Steel East, we buy in bulk so our customers don’t have to.

Processing and Freight

Processing

Cutting to length, plate burning, drilling, cambering, and bending can show up as separate line items or be built into a piece price. Either way, weigh the charge against what the same work costs in your own shop: labor, machine time, and the drops left over from full-length stock. Ordering steel cut to length reduces waste and handling, and our value-added services cover cutting, plate processing, cambering, and bending before material ships.

Freight

Delivery gets priced several ways. Common carriers often quote less-than-truckload freight per CWT, and some loads carry charges of their own; one mill price list even lists tarping a truckload as a separate extra. Ask whether delivery is included in the material price or listed separately, and confirm the delivery window.

Timing affects cost too. Next-day delivery on stocked items lets you order closer to when you’ll use the steel, instead of storing it on site and handling it twice.

Why Steel Quotes Expire

Because base prices move, steel quotes are only good for a limited time, and the window is often short. Check the expiration date on every quote, and expect a requote if you order after it passes.

On longer projects, a few steps help manage price risk:

Order before the quote expires. Accept the quote and place the order inside the window it states.
Ask about phased releases. If material is needed in stages, ask how pricing works for each release.
Consider an escalation clause. Contractors can negotiate a price escalation clause into a fixed-price contract so that material increases above a set trigger after bid day can be adjusted. Standard AIA contract forms haven’t traditionally included one, so the wording matters. ConsensusDocs publishes an amendment for time- and price-impacted materials. Have your attorney review any clause before you rely on it.

Some public owners already handle this in the contract. The state DOT steel price adjustment provisions mentioned above tie payments to a published steel index.

How to Compare Steel Quotes

The lowest price per CWT and the lowest cost for the job can be two different quotes. Before you compare totals, make sure each quote covers the same things:

Specification and grade, including any dual certification the drawings rely on
Lengths and cut tolerances, since full stock lengths and cut-to-length pieces carry different shop costs
Processing, listed piece by piece
Mill test reports, when the job requires them
Freight, and whether the delivery date works with your schedule
Availability, because a lower price on material with a long lead time can cost more in schedule than it saves
The quote’s expiration date

A complete request gets a complete quote. Include grades, sizes, lengths, quantities, processing, documentation needs, and the delivery location.

Frequently Asked Questions

What does CWT mean in steel pricing?

CWT means hundredweight. In the U.S., one hundredweight is 100 pounds, so a price of $50.00 per CWT equals $0.50 per pound. Mill price lists and some state DOT steel price indexes use CWT.

How do you calculate steel cost from a CWT price?

Find the weight in pounds, divide by 100 to get CWT, and multiply by the CWT price. Ten 40-foot W12x26 beams weigh 10,400 pounds, or 104 CWT, so at an example price of $50.00 per CWT the base material comes to $5,200. Extras, processing, and freight are added on top.

How much does structural steel cost per pound?

There’s no single number. The price per pound depends on the market, the product and grade, the size, the quantity, any processing, and delivery, and it changes over time. Converting every quote to a price per pound or per CWT makes them easier to compare.

What are extras in steel pricing?

Extras are charges added to the base price for anything outside the standard product. Mill price lists commonly include extras for non-standard lengths, special grades such as weathering steel, cutting, and testing, along with minimum order quantities.

How long is a steel quote good for?

It depends on the supplier, and the expiration is usually stated on the quote. Because steel prices move with the market, the window tends to be short, so check the date and confirm pricing if you order after it passes.

Is it cheaper to buy steel from a mill or a service center?

It depends on the order. Mills sell in large minimum quantities and roll each size on a schedule. Service centers buy in mill quantities, hold inventory, and sell the amounts a job needs, often with processing and delivery. For a project-sized order needed soon, a service center is often the practical choice.

What is the difference between a short ton and a metric ton?

A short ton, the ton usually used in U.S. steel pricing, is 2,000 pounds. A metric ton, or tonne, is about 2,204.6 pounds. A long ton, also called a gross ton, is 2,240 pounds.
