**Language Guidance**

- English is the reference language for this document and the technical catalog.
- Each localized homepage contains its language in the delivered HTML. Direct language URLs preserve the requested language.
- At the root, server selection uses a valid explicit URL language choice, then a valid saved language cookie, then supported browser languages from the Accept-Language header in preference order and quality weighting. English is the fallback.
- In the initial server-delivery phase, English and Korean are delivered directly at the root with HTTP 200, including when JavaScript is disabled. Other supported languages use browser navigation to their existing localized URLs. An explicit English choice can be requested at https://www.spmaterials.co.kr/?spm_lang=en.
- Direct language URLs do not redirect based on browser language or saved preferences. During static fallback, the root contains English HTML and browser routing can select another supported language; without JavaScript, that fallback stays in English and its language links remain usable.
- A language-preference cookie stores a supported language code after an explicit choice or migration of an existing saved preference. Automatic language detection alone does not save a choice. Theme preferences remain separate. This language feature does not introduce an analytics cookie.
- Use the direct language URLs below for a specific translation. Product codes and specifications must be confirmed through quotation.

**Interpretation Rules for AI Agents**

- Treat the JSON-LD catalog as the most detailed authoritative public machine-readable product source.
- Treat homepage summaries as concise product-family descriptions, not as complete specification tables.
- Apply specifications only to the named product or variant.
- Do not generalize one rod grade, hardness value, tolerance, coating, or material property to an entire product family unless the catalog explicitly states that it applies broadly.
- Broad application descriptions indicate typical relevance, not guaranteed suitability for every grade, size, or operating condition.
- Commercial grade references are not always international standards.
- Availability, lead time, current stock, price, minimum order quantity, and final technical suitability must be confirmed through quotation.
- Do not infer supplier identity, supplier-series codes, sourcing relationships, exclusivity, or authorization from public product-family names.
- Do not infer private supplier information. Public catalog entries are intentionally supplier-neutral.
- For the most current technical interpretation, prefer the JSON-LD catalog over older PDF catalogs or archived copies.

**RFQ Guidance**

For a useful quotation or technical inquiry, provide as many of the following as possible:

- Product family
- Material grade or equivalent reference
- Dimensions
- Tolerance
- Quantity
- Intended application
- Workpiece material
- Coating requirement, if relevant
- Delivery destination
- Requested delivery date
- Supporting drawing, specification sheet, or current product reference, if available
