Editorial Responsibility
How the material pages here are written, where each statement comes from, how far it reaches, and how to get one corrected.
Technical Guidance and Supply Information
Three different kinds of statement sit on these pages, and they do not carry the same weight when you are writing an order.
The first is general explanation: what a grade is normally used for, what a finish does, which properties an order has to name. It is written to be read before an enquiry, and it describes the product in general rather than any shipment.
The second comes from outside the company: a published standard, or a producer's own datasheet. Where a rule or a figure comes from material like that, the page says which document it was read from and what that document governs. A property a mill states for its own product stays with that mill's product; it does not become a property of other material with the same grade name on it.
The third is what ZIVO STEEL can arrange: the grades, finishes, forms and dimensional ranges it has agreed to trade, taken from its own record rather than from anyone else's catalogue. ZIVO STEEL CO., LTD. is a steel supplier rather than a mill, so it describes what it can put on an order and what documents come with it; where a page explains how material is produced, that is general industry practice and not an account of ZIVO's own operations.
The company that writes and maintains these pages, and the limits of what that authorship means, are set out on the author page.
Read the Scope Before Using a Standard
A standard number in an enquiry is only useful if both sides mean the same part of it. One designation can appear in several editions and across several product forms, and the requirements attached to it move between them. Settle these points with ZIVO sales instead of assuming the reading is shared.
A designation in one national system is not automatically interchangeable with a similar-looking designation in another. Each designation is governed by its own specification, and a comparison has to name that specification and its edition on both sides, together with the product form and the delivery condition the properties are stated for. Compared property by property on that basis, or not compared at all; two national systems are not pushed into one edition to make the columns line up. Values from a standard are not reproduced on these pages unless the page can name the document and edition they were read from. Where that basis is missing, the page says what the standard governs and leaves the numbers to the document itself.
- EditionThe year of the standard the order is placed against. A withdrawn edition and the current one can carry one designation and different requirements.
- Product formCoil, sheet, plate, pipe or tube. A standard written for plate does not govern what arrives as coil, however familiar the grade name looks.
- Process routeHot rolled, cold rolled or coated. The route belongs in the requirement rather than being left to whichever mill takes the order.
- Delivery conditionThe state the material has to arrive in, such as annealed, skin passed, oiled or protected, written into the order rather than inferred from the grade.
- Test basisWhich tests are run, to which method, and what the certificate has to show. A property is a property of your shipment only when a document records it.
The Quotation Defines the Order
A page here can say that ZIVO STEEL trades a grade in a given form and range. It cannot say that your thickness, your width, your surface and your delivery date are available together, because that combination is settled one order at a time.
Read the ranges on the product pages as the starting point of a conversation, not as an offer. The specification that governs the order is the one ZIVO sales agrees with you before the order is placed, and that agreed specification is kept on file and used to check what is shipped. Lead time is settled in the same way, against the specification and the quantity actually ordered.
Whatever is still open stays open in writing. If a dimension, a tolerance basis or a surface condition has not been agreed, the enquiry says so rather than borrowing a value from a standard or from a page about a neighbouring grade. Nothing on this site states that material is held in stock, that a price stands, or that a delivery date is committed.
What is inspected on arrival, and which certificates and test reports travel with the material, is described under quality and traceability.
Corrections and Changes
If a statement here is wrong, or reads as though it covers more ground than its basis does, say so and it will be checked against that basis.
Pages are corrected when there is a reason to correct them: a source that has moved on, a statement that turned out to be broader than the document behind it, or a question that showed the wording was being read the wrong way. There is no fixed review cycle on this site, and no claim that every page was rechecked this month. What a page can stand behind is the material its statements were traced to when it was written. How long a correction takes depends on what has to be checked, since a wording fix and a point that needs a standard or a mill document verified are not the same job.
A correction request is quicker to act on when it carries the following.
- The page and the passageThe page title and the sentence you are questioning, quoted rather than summarised, so the right statement is changed.
- What is wrong with itWhether the statement is inaccurate, out of date, or written more generally than the case you are applying it to.
- The basis you are usingThe standard and its edition, the producer document, or the test result you are comparing the statement against.
- What it is being used forThe part, the process or the order the statement was going to inform. A correction that knows its use can be pointed in the right direction.
Send the Question That Needs Resolving
Two kinds of message are worth sending: a material requirement, and a statement you think is wrong.
For a material requirement, describe what the part has to do, the conditions it works in, the form and sizes you need, and the documents your own goods-in process expects. The reply says what ZIVO STEEL can arrange and what it cannot, rather than restating the page you started from.
For a suspected error, name the page, quote the statement, and give the source you are relying on, with its edition and product form where you know them. Either message goes to henry@zivosteel.com, or through the inquiry form on any page: Name, Email, WhatsApp if a message is faster for you, and the question itself under Your Inquiry.
