What drives the price of steel and aluminium

Steel and aluminium are traded goods, so their price is built up rather than set: a base metal cost that moves with raw materials and energy, plus surcharges and premiums that reflect grade, form and region. Aluminium is quoted as the exchange price plus a regional delivered premium plus a conversion premium for the shape supplied, while stainless carries a monthly alloy surcharge driven by nickel, chromium and molybdenum, which is why 1.4404 sits above 1.4301. On top of that sit the job-specific factors a buyer actually controls: specification, dimensions, coating, certification, quantity and lead time. This guide explains each layer, so an enquiry can be framed in the terms that move a quotation.

Why there is no single price for steel or aluminium

Steel and aluminium are not one product with one number attached. The metal in a 3 mm sheet of 1.4301 stainless, a 6 m length of EN AW-6060 T6 profile and an S355J2 structural section shares almost nothing commercially: different raw materials, different production routes, different alloying content and different processing. A headline figure quoted in the trade press describes one benchmark, usually hot-rolled coil at mill level, and does not translate into what a specific item costs delivered. This is why serious supply runs on quotations against a specification rather than a published list, and why the useful question is not what metal costs, but which factors are moving the figure on a given enquiry.

The two layers: base metal and everything above it

Almost every metal price in Europe separates into two layers. The first is the base metal cost, driven by global raw materials, energy and the balance of supply and demand, and largely outside the control of either buyer or supplier. The second layer covers what happens to that metal on its way to a specific job: the grade selected, the form it is rolled or extruded into, the surface treatment, the documentation, the quantity and the transport. The first layer explains why prices move month to month across the whole market. The second layer explains why two enquiries placed on the same day for the same tonnage, one for S235JR sections and one for 1.4404 sheet, come back with very different figures.

Steel: raw materials and the production route

Raw materials are the largest single cost in making steel, and which raw materials matter depends on the route. Integrated mills using a blast furnace and basic oxygen converter consume iron ore and coking coal, so their costs track those markets. Electric arc furnace mills melt steel scrap, so their costs track scrap and electricity instead. The two routes therefore respond to different pressures, and a shift in scrap availability can move prices for sections and merchant bar while ore-linked flat products behave differently. For the buyer, the practical consequence is that structural steel such as structural steel S235JR, S275JR and S355J2 and flat products do not always move in step.

Energy, and why it matters more for aluminium

Energy is the second major input, and it is not spread evenly across metals. Primary aluminium is produced by electrolysis, which consumes in the order of 14 to 15 kWh of electricity for every kilogram of metal and makes it one of the most electricity-intensive materials in industry, so aluminium prices are sensitive to power costs in a way that carbon steel is not. Electric arc furnace steelmaking is also exposed to electricity, while blast furnace operations are more exposed to coal and gas. Remelting and casting add further energy cost to any product that is not sold as raw metal. When European energy markets move sharply, the effect appears first in aluminium and in electric arc furnace products, and only later in the wider steel market.

Aluminium: exchange price plus premiums

Aluminium pricing is explicit about its layers, which makes it easy to read once the structure is known. The London Metal Exchange price is the global reference for primary metal. On top of it sits a regional physical premium, quoted duty paid for delivery into Europe, which covers freight, insurance, handling, import duty and the local balance of supply and demand. A further conversion premium applies to the form supplied: extrusion billet has to be cast, scalped, homogenised and inspected before it can be extruded, and that work carries its own cost, of which remelting energy is a significant part. A finished extrusion therefore sits above the exchange price by two distinct steps, which is why the headline aluminium figure alone never describes what a profile costs. Alloy and temper follow the same logic, as set out in the guide to EN AW aluminium alloys.

Stainless: the alloy surcharge

Stainless steel is priced as a base price plus a separate alloy surcharge, and understanding that split answers most stainless pricing questions. The alloying elements that make stainless what it is, chiefly nickel, chromium and molybdenum, are volatile in their own markets, so European mills publish a monthly surcharge that reflects their recent average value and negotiate the base price over longer periods. Nickel is exchange-traded, so its contribution can be read from the London Metal Exchange. Molybdenum is settled against a published physical assessment rather than discovered on an exchange, and chromium is neither exchange-traded nor tied to a single benchmark, being negotiated or index-referenced between producers and mills. The surcharge is calculated on an averaging period and published monthly, so it lags spot movements by a month or two rather than tracking them daily.

Why 1.4404 costs more than 1.4301

The most common stainless pricing question has a precise answer in the surcharge. Grade 1.4404 carries 2.0 to 2.5 per cent molybdenum that 1.4301 does not, added specifically to improve resistance to chlorides and pitting, and it also specifies a higher nickel range, roughly 10 to 13 per cent against 8 to 10.5. Because the surcharge is calculated from the alloy content of each grade, the molybdenum-bearing grade carries the higher surcharge, and the gap between the two widens and narrows with the nickel and molybdenum markets rather than staying fixed. The engineering conclusion follows from the commercial one: specifying the molybdenum grade where the environment does not require it pays a premium for corrosion resistance that will never be used. Our guide to 304 and 316 stainless steel covers where each grade is genuinely needed.

Grade and specification

Within a metal family, the specification moves the figure. A higher strength structural grade such as S355J2 carries tighter chemistry and impact requirements than S235JR, and grades with guaranteed low-temperature impact properties are more demanding to produce than those without. In aluminium, a structural alloy such as EN AW-6082 is not commercially the same as a general extrusion alloy such as EN AW-6060, and temper adds a heat treatment step. Specifying above what the application needs is one of the most common avoidable costs in metal buying. Specifying below it is worse, so the discipline is to let the design and the standard set the grade rather than habit. Choosing between the metals in the first place, rather than a grade within one, is a separate engineering question compared in our guide to aluminium versus steel.

Form, processing route and dimensions

The same tonne of metal costs differently depending on what has been done to it. Every processing step, rolling, extruding, welding, drawing, cold finishing, adds cost, so a cold-rolled product sits above a hot-rolled one, and a precision-drawn tube above a welded one. Dimensions matter in a second way: standard sizes such as 6,000 mm stock lengths run frequently and are widely stocked, while unusual thicknesses, widths or wall combinations may need a mill rolling to order, with the lead time and minimum quantity that implies. Thin gauges and very heavy sections both cost more per unit of mass than the middle of the range. The most economical specification is usually the one closest to what the market already runs as standard.

Coating and surface finish

Protective and decorative finishes are a distinct cost layer applied after the base material. On steel, a zinc coating adds the cost of the zinc itself and the coating process, and heavier coating classes cost more than lighter ones, which is why coating class is specified to the corrosion environment rather than chosen at maximum. Powder coating adds a further process and makes colour a commercial variable, since standard stocked colours are cheaper to supply than a special. Mill finish, where the surface is left as produced, is always the lowest cost option. The trade-off is straightforward: coating cost is paid once, while corrosion protection is recovered over the service life, a comparison set out in the galvanised steel DX51D guide.

Quantity, stock and availability

Quantity works through availability rather than through a simple discount ladder. Material held in stock can be supplied against a short lead time and priced from the position held, while an item that has to be brought in specially carries mill quantities and a longer wait. Consolidating a project onto one order and one delivery is generally more economical than a sequence of small calls, because each movement carries its own handling and freight, and ULAMEX dispatches stocked material within 2 to 7 working days. Mixed orders across several materials from a single source avoid multiple deliveries. ULAMEX applies no minimum order on stocked items, so the practical question is what is held rather than what threshold has to be met.

Certification as a cost factor

Documentation is part of the specification and therefore part of the cost. Material supplied with a type 3.1 inspection certificate has to be kept segregated and traceable to its heat number through the supply chain, which is a real operational discipline rather than a piece of paperwork added at the end. Where a contract calls for third-party verification under a type 3.2 certificate, an external inspector is involved and the arrangement is made for that job. Both are routine in structural and quality-critical work, and both are worth stating on the enquiry rather than discovering later, because certified and uncertified material cannot be substituted for one another. The types are explained in the guide to EN 10204 material certificates.

Lead time and urgency

Time is a commercial variable like any other. Material taken from stock is quoted differently from material that has to be rolled or extruded to order, and an urgent requirement narrows the options to whatever is physically available rather than whatever is most economical. ULAMEX works to a lead time of 2 to 7 working days on stocked material, with same-day dispatch possible on established accounts. Planning an enquiry far enough ahead to allow a normal lead time is one of the few cost levers entirely in the buyer’s hands, and it costs nothing to use.

Freight, weight and logistics

Metal is dense, so delivered cost is shaped by mass and by how well a consignment fills a vehicle. The difference between metals is large: carbon steel is taken at 7.85 g/cm3 against 2.70 for aluminium, so an identical parts list in the two materials produces very different freight. Freight is driven by weight, distance and handling, and a load that is heavy for its volume behaves differently from one that is bulky and light. This is where calculating the consignment mass in advance pays off, both to check the vehicle and lifting arrangements and to see whether combining items into one delivery is worthwhile. The method is set out in the metal weight guide. Packaging, timber bearers and banding add a small further cost, and awkward lengths that will not fit a standard trailer cost disproportionately more to move.

Trade measures and carbon costs

Two regulatory layers now sit in the background of European metal pricing, and both changed in 2026. Import measures on certain steel categories work through tariff-rate quotas, with a substantially higher duty on volumes arriving beyond quota, so they affect how much material can enter the European market on normal terms and therefore affect availability and price when quotas are tight. The framework was reset in mid-2026, with quota volumes cut sharply and the out-of-quota duty doubled, and from 1 October 2026 importers have to be able to evidence the country where the steel was melted and poured, typically from the mill test certificate. That requirement lands on documentation rather than on the metal itself, which is one more reason certified material with a full paper trail is worth specifying.

Separately, the Carbon Border Adjustment Mechanism entered its definitive phase on 1 January 2026, covering iron and steel and aluminium among other goods. Importers above the de minimis threshold of 50 tonnes per calendar year must hold authorised declarant status, with certificate sales opening in 2027 and the first declaration and surrender, covering 2026 imports, due by 30 September 2027. Certificates are priced against European emissions allowances. Both mechanisms are market conditions rather than line items on a quotation, but they form part of why European metal prices behave as they do.

What determines a quotation from ULAMEX

A quotation is built from the enquiry, which is why a precise enquiry returns a precise figure. The variables that matter are the grade and standard, the form and dimensions, the quantity, the coating or finish, the certificate type and the delivery point and date. ULAMEX brings 38 years of experience in European steel and aluminium trading and has been in the metals wholesale industry since 1988, manufacturing its own structures under EN 1090-1 EXC2 and ISO 3834-2. Quotations are non-binding and stated with lead time and availability, so a project can be costed before it is committed.

Send the grades, forms, dimensions, quantities and certificate requirements your project calls for, and ULAMEX will return a non-binding quotation.
