Planned updates
A normal rhythm plus milestone notices can be agreed for the project.
Project Evidence Package
Steel Structure Production Records for Overseas Buyers
YYN helps buyers collect agreed production milestone records so important project details are easier to review from outside China.
Project Evidence Package
Milestone records that can support overseas buyers
YYN coordinates collection of the agreed key production milestone records from the responsible project parties to help buyers understand progress from drawings to export handover. The exact record scope is confirmed before order follow-up.
| Stage | What YYN Can Record | Why It Helps Buyers |
|---|---|---|
| Drawing Review | Missing information, quotation assumptions, scope notes | Helps prevent unclear quotation scope |
| Raw Material Arrival | Material arrival photos and basic records | Shows production preparation |
| Cutting | Cutting photos and member marks | Shows fabrication progress |
| Assembly | Assembly photos or short videos | Shows component formation |
| Welding | Welding progress photos and notes | Helps track key fabrication stages |
| Shot Blasting | Surface preparation photos | Shows preparation before coating |
| Painting / Coating | Coating process, color, and layer notes when agreed | Helps reduce coating misunderstandings |
| Fireproof Coating | Fireproof coating progress when required | Supports buyer-side project tracking |
| Inspection Notes | Dimensions, holes, weld appearance, coating, or packing notes when agreed | Helps buyer check agreed items |
| Packing | Bundle marks, package photos, accessory box photos | Helps site receiving |
| Container Loading | Loading photos, container number, loading sequence | Shows shipment handover |
| Export Documents | Packing list, invoice coordination, shipping marks, and document checklist | Helps import preparation |
Project Reporting Frameworks
Fifteen practical report layouts for scope, cost, progress, records, and handover.
Each layout shows the information that can be organized during an order. The final reporting package, update frequency, and responsible parties are confirmed in the order scope.
Sample notice: These are simulated and redacted reporting templates using fictitious or redacted fields. They do not represent a real customer, project, certificate, inspection, approval, production status, or outcome.

Update Rhythm & Confirmation Gates
Records are useful when timing, owner, and decision status are clear.
The exact update frequency and record list are agreed before order. Critical confirmations can be linked to drawing release, coating, packing, shipment release, and arrival issue review.
Open actions
Each issue records the owner, due status, and required confirmation.
Release gates
Drawing, coating, packing, and shipment release points are defined by the order scope.
Inspection boundary
Factory QC or the appointed third party performs formal inspection; YYN coordinates agreed records.

Material Traceability Subset
Where the order requires a material identity chain, the steel material traceability records guide shows how source documents, heat or lot references, controlled mappings, member marks, exceptions, and handover status can be defined as one subset of the wider evidence package.
Evidence framework
Verify the current order with identified records, not generic claims.
Agree the required record, timing, responsible party, and acceptance route before production. Photographs support visibility but do not replace drawings, measurements, inspection, testing, or signed acceptance.
Evidence boundary: These are reference images shown for context. Project-specific scope, measurements, inspection status, and acceptance must be confirmed through controlled order records.
Define the working scope
Send your project facts, current documents, required records, and delivery target.
YYN will confirm what can be coordinated in China and which responsibilities must remain with other appointed parties.
