About YIHE

YIHE is the modular structure brand of YICK WO INTERNATIONAL TRADING LIMITED, a Hong Kong-registered company. We connect clients with manufacturing partners across China and coordinate product selection, production follow-up, quality checks, delivery and after-sales support.

Our value is to turn a broad supplier market into a clear, manageable project process: a shortlist matched to your needs, comparable proposals and one point of coordination from enquiry through after-sales. Manufacturing is carried out by our selected partners.

Cooperation model — schematic, not a factory-location map.

Different production lines have different strengths in structure types, materials, enclosure systems and project scale. We work with partners according to the products and processes they do well, rather than fitting every enquiry into one factory's catalogue.

We first clarify intended use, site conditions, dimensions, budget, schedule and operating requirements. We then shortlist suitable manufacturers and configurations, compare scope and supporting documents, and explain the trade-offs in materials, accessories, delivery and cost. You can make a decision on a consistent basis.

Product configuration reference. Final supplier and specification depend on the project.

Before production, we coordinate confirmation of drawings, materials, configuration, supply scope and the inspection points agreed for the project. During production, we follow key milestones, request progress updates and inspection records, and track questions or changes with the manufacturing partner.

Before dispatch, we coordinate the agreed checks on dimensions, finish, components, quantities, packing and documentation, as applicable to the order. Identified issues are recorded, assigned for correction and followed through. The inspection method, evidence, responsibilities and any independent inspection are defined in the project agreement.

Manufacturing partner process reference. Not a YIHE-owned production line.

We coordinate packing information, dispatch schedules, logistics interfaces and handover documents, and clarify site preparation and installation responsibilities. Where installation support is included, we help connect the site team with the manufacturing partner for drawings, instructions and technical questions.

Our follow-up continues after delivery. We collect feedback, record missing or damaged items and operating questions, and coordinate the responsible supplier's response, agreed corrective actions, replacement parts and warranty handling. The supply agreement defines service scope and response arrangements; YIHE remains your coordination contact throughout.

Installation application reference. Project services and responsibilities are agreed separately.
