This is what a buyer checks before they shortlist a metals and metalworking supplier.

What does a buyer check before placing a steel order with a new supplier?

They check the grade against a named standard, whether you can issue a mill test certificate traceable to a heat number, and whether you are the mill or a stockist. Those three facts decide whether your quote can be compared with the others on the buyer's desk.

A project buyer is comparing three quotes and needs to know which of them can actually supply against the specified standard.

Every claim on a supplier site has a document behind it or it does not. Buyers in steel and tmt know which is which.

What a buyer needs to identify the product

These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.

  1. 1

    Grade and standard

    IS 2062 E250, IS 1786 Fe 500D, ASTM A36 — the grade only means something beside its standard.

  2. 2

    Section, size and thickness range

    Tells the buyer immediately whether their bill of materials is inside your range.

  3. 3

    Dimensional tolerance standard

    Fabricators plan around the tolerance, not the nominal size.

  4. 4

    Heat or cast number traceability

    The link between the physical steel and its certificate.

  5. 5

    Coating or finish

    Galvanised, painted and bare change both price and application.

  6. 6

    Length, packing and loading unit

    Determines transport cost and site handling.

  7. 7

    Mill or stockist

    Changes what the buyer can expect on lead time, certification and minimum quantity.

The documents buyers ask for

Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.

Documents buyers ask a steel producer or stockist for, what each proves, and whether it belongs on the public site

Where steel and tmt sites lose the enquiry

Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.

  • "Export quality" with no standard named

    It is the phrase buyers most associate with a supplier who cannot meet a named standard.

  • No sample mill certificate anywhere on the site

    A redacted sample certificate answers more questions than any amount of copy about quality.

  • Stockists presenting themselves as mills

    The buyer discovers it at the certificate stage and the relationship starts with a correction.

What the enquiry form should ask

A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.

Enquiry form — steel and tmt

Enough to reply usefully, short enough that a buyer finishes it.

Grade and standard
No quote is possible without it.
Section, size and quantity in tonnes
Drives price, rolling schedule and freight.
Certificate type required
3.1 and 3.2 are different costs.
Third-party inspection requirement
Affects lead time and needs planning.
Destination port or site
Freight is a material part of the landed price.
Delivery schedule
One shipment or a call-off over a quarter changes the whole quote.

Questions suppliers ask

Should a stockist say so on the homepage?

Yes, and it is an advantage rather than an admission. Buyers with urgent or mixed-grade requirements are specifically looking for stock, and they cannot find you when your site is written to imitate a mill. State the role and let each buyer self-select.

Is publishing a redacted mill certificate risky?

Not if you remove the customer, the price and the order reference. What remains — the format, the standard, the heat number field, the signatures — is exactly what a new buyer is trying to establish, and no paragraph of prose substitutes for it.

How much should we say about capacity?

State the rolled sections and sizes you actually produce, and the practical monthly tonnage in each. Buyers use capacity to judge whether their order will be prioritised or squeezed, so a specific figure is more reassuring than a large vague one.

Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
