Product Review Points
Sourcing support for steel frames, columns, beams, bracing, purlins, connection parts, coating coordination, packing records, and export handover.
Drawings, country, city, estimated tonnage, building use, local engineer status, coating or fireproof coating needs, and target schedule.
Factory fit depends on tonnage, structure type, welding workload, coating process, schedule, destination country, and available capacity.
Agreed records may include material arrival photos, cutting, assembly, welding, coating, inspection notes, packing photos, and container loading records.
YYN supports China-side sourcing, factory matching, production follow-up, agreed project record collection, and export handover coordination. Local structural design approval, local building code compliance, permits, site installation, and authority approvals must be confirmed by the buyer's local engineers or consultants.

Buyer Decision Table
These points help buyers clarify the quotation scope before factory matching and production follow-up.
| Buyer Decision Point | Why It Matters | What YYN Follows |
|---|---|---|
| Clear span | It affects frame design, usable storage area, and column planning. | YYN checks whether drawings show the intended clear span and highlights missing scope points. |
| Column layout | Column positions influence racking, forklift movement, and future use. | YYN follows drawing notes and helps communicate layout assumptions before quotation. |
| Roof and wall cladding | Cladding affects weather protection, insulation, and packing volume. | YYN tracks cladding scope, color notes, and accessory packing when agreed. |
| Door and opening positions | Wrong openings can delay installation or site use. | YYN checks whether door, window, and ventilation positions are included in drawing review. |
| Packing marks | Clear marks help the site team sort members faster. | YYN follows bundle marks and package photos before shipment. |
| Destination port planning | Shipment planning affects packing, container use, and handover documents. | YYN coordinates destination port notes and export handover scope. |
Warehouse Procurement Focus
Warehouse orders often depend on grid dimensions, loading doors, canopies, bracing, purlins, cladding interfaces, gutters, bolts, and package zoning. These items should be aligned with drawings and site receiving before production release.
Secondary steel and accessories may be omitted when quotations are compared only by main-steel tonnage.
Grid, base, bracing, opening, and cladding interfaces need the correct drawing revision.
Group members and accessories by building zone or erection sequence.
Member marks, accessory boxes, package list, and loading sequence.
Evidence framework
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 from YYN's documented image library. Project-specific scope, measurements, inspection status, and acceptance must be confirmed through controlled order records.
