Why Do Steel Structure Quotations Expire?
A steel structure quotation is not a permanent price. It is based on the steel price, exchange rate, freight rate and available capacity at the time the offer is made, and these move over time, so suppliers set a validity period. Confirming and placing the order within the validity period, and arranging the agreed deposit to reserve material, reduces exposure to price changes. Whether a price is fixed or adjustable should be clear in the contract. ZhongSai states its assumptions and validity in every quotation.

This guide explains what makes up a quotation, why prices change, what a validity period means, and how to manage price movement as a buyer.

What a steel structure quotation includes
- Material: the steel sections, plates, purlins, cladding and fasteners
- Fabrication: cutting, welding, drilling, coating and marking
- Surface treatment: the agreed blast-cleaning and coating system
- Packing and container loading: marking, packing and loading
- Export coordination: documentation and port handling for the agreed scope
- Freight and trade terms: where the price is quoted under the agreed Incoterms
- Tax and duties: handled according to the trade term and destination
Why a quotation changes or expires
- Steel price: the main raw material moves with market supply and demand
- Exchange rate: most export steel is priced against a major reference currency
- Ocean freight: container rates and space vary with the shipping market
- Specifications: scope, loads, coating or cladding changes alter the tonnage
- Capacity: busy periods and lead times affect the quoted price
- Time: the longer the gap between quote and order, the more assumptions may change
A quotation that no longer reflects the supplier’s current cost is usually re-issued.
What quotation validity means
The validity period is the time during which the supplier will accept the order at the quoted price. The length depends on the supplier, the market and how volatile costs are; it is not a fixed global number. It usually starts when the written quotation is issued and ends on the stated date, after which the price may be re-confirmed.
Fixed price versus adjustable price
| Item | Fixed price | Adjustable / provisional price |
|---|---|---|
| What is held | The agreed price for the agreed scope | Price subject to a defined trigger |
| Buyer risk | Lower if signed within validity | Shares some cost movement |
| Common trigger | None, once contract is signed | Steel index, exchange rate or freight |
| When to use | Clear, near-term orders | Long-lead or uncertain projects |
| Must be clear | Scope and what is excluded | The formula and adjustment date |
The wording must be read carefully: a fixed price is generally fixed for the agreed scope and validity, not for changes the buyer introduces later.
Which parts move most
- Steel and cladding: linked to material markets
- Ocean freight: can move separately from steel
- Exchange rate: affects the local-currency cost of an import
- Coating: changes with paint systems and corrosion grade
- Handling and documents: usually more stable than material and freight
How to reduce price-change risk
- Confirm the scope and drawings before asking for the final price
- Check the validity period and what assumptions it is based on
- Place the order within the validity window
- Arrange the agreed deposit to reserve material
- State whether the price is fixed or adjustable in the contract
- Avoid repeated scope changes that trigger re-quotation
- For long-lead projects, agree the adjustment formula in writing
Reasonable versus questionable changes
A re-quotation tied to a documented change in steel, freight, exchange rate or your own specifications is generally reasonable. A change with no explanation, repeated last-minute increases after the deposit, or new fees not shown in the quotation should be questioned in writing. Ask for the cost basis and keep the quotation, e-mails and payment records.
Responsibility boundary
| Stage | ZhongSai | Buyer / local party |
|---|---|---|
| Quotation | State price, assumptions, scope and validity in writing | Provide complete drawings or requirements |
| Price basis | Show the agreed trade term and what is included | Confirm duties and local import costs |
| Order | Confirm the price once the deposit is arranged | Place the order within the validity period |
| Changes | Re-quote only for documented scope changes | Avoid late specification changes |
| Contract | Clarify fixed versus adjustable terms | Review and sign the agreed terms |
Buyer checklist

- Validity period is stated in writing
- Fixed or adjustable price is confirmed
- Deposit and material reservation are understood
- Freight and exchange-rate assumptions are known
- Process for scope changes is agreed
- Quotation and messages are kept on file


FAQ
Why does a steel quotation have an expiry date?
Because steel prices, exchange rates, freight and capacity move; the offer is only held for the stated period.
How long is a quotation valid?
It depends on the supplier and market conditions; the validity should be written on the quotation rather than assumed.
Can the price change after I order?
A fixed price for an agreed scope is usually held after signing, but buyer-introduced scope changes may be re-quoted.
What changes the price most?
Material and freight often move the most, while the exchange rate affects the local-currency cost.
Does a deposit lock the price?
A deposit arranged to reserve material reduces exposure, but the exact terms should be confirmed in the contract.
What is the difference between fixed and adjustable prices?
A fixed price is held for the agreed scope and validity; an adjustable price follows a defined steel, freight or exchange-rate trigger.
Why was my re-quote different?
A change in steel, freight, exchange rate or your specifications can change the price; ask for the cost basis.
How can I avoid price surprises?
Complete the drawings early, order within the validity, and agree the fixed-versus-adjustable terms in writing.
