How YYN Works

How Overseas Buyers Work With YYN From Drawings to Shipment

YYN acts as a China-side steel structure sourcing and production follow-up partner. We help buyers clarify scope, match suitable factory resources, follow agreed key milestones, and coordinate export handover without claiming to replace local engineers or approval bodies.

Buyer Cooperation Process

Seven steps for working with YYN

This is the commercial cooperation flow between the overseas buyer and YYN.

01

Send drawings

Share available architectural drawings, structural drawings, sketches, or a secure drawing link.

02

Review scope

YYN checks the project use, destination country, rough tonnage, coating needs, and missing quotation information.

03

Match factory resources

Factory resources are matched by structure type, schedule, coating requirement, member size, and availability.

04

Confirm quotation scope

The quotation scope is clarified before order discussion so exclusions, assumptions, and document boundaries are visible.

05

Confirm order and project owner

After commercial terms are agreed, YYN assigns a named primary China-side coordinator. Larger or more complex orders receive additional team coverage with the responsibility split communicated at kickoff.

06

Follow production milestones

Agreed key production milestone records are collected and reported during fabrication.

07

Coordinate packing and export handover

YYN follows packing marks, loading records, and export document handover according to the agreed scope.

Transparent Project Ownership

Know who owns the next action.

The kickoff record identifies the project reference, primary coordinator, contact route, update rhythm, backup route, and any supporting roles for technical documents, production follow-up, commercial coordination, inspection interfaces, or logistics.

Production Milestones YYN May Follow

Nine factory milestones that can be recorded when agreed

These are production-side checkpoints. The exact record scope depends on drawings, project type, factory cooperation, and buyer requirements.

01

Drawing review

Review drawing completeness, assumptions, and missing information before quotation or production.

02

Raw steel arrival

Collect material arrival photos and basic preparation records when included in the follow-up scope.

03

Cutting

Follow cutting progress, member marks, and CNC processing records where available.

04

Assembly

Record component assembly progress so buyers can see how members are formed.

05

Welding

Follow welding progress and notes for agreed key fabrication stages.

06

Shot blasting

Record surface preparation before painting, galvanizing, or other coating work.

07

Coating / fireproof coating

Follow paint, galvanizing, or fireproof coating requirements according to buyer specification and local engineer direction.

08

Inspection coordination

Coordinate agreed records issued by factory QC or the appointed inspector for dimensions, hole positions, weld appearance, coating, or packing readiness.

09

Packing and loading

Follow package marks, accessory boxes, loading sequence, container number, and export handover documents.

Two Connected Workflows

Commercial order control and factory production are tracked separately.

The buyer workflow covers scope, quotation, contract, payment details, written changes, shipment release, and arrival support. The production workflow covers materials, cutting, assembly, welding, surface treatment, inspection, packing, and loading.

Before order

Confirm drawing revision, scope, exclusions, delivery basis, responsibilities, and quotation validity.

Order start

Confirm the contracting entity, payment route, project ID, primary contact, baseline plan, and open items.

During production

Track agreed milestones, changes, schedule variance, inspection roles, and buyer decisions.

Before and after shipment

Confirm packing, accessories, documents, loading, release status, and arrival issue coordination.

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.
