System requirement matrix
We structure dimensions, profiles, glazing, hardware, finishes, performance and documentation requirements.
SUNROOMS · PERGOLAS · ALUMINIUM SYSTEMS
For distributors, installers and project buyers sourcing sunrooms, bioclimatic pergolas, sliding systems and related components from China. We connect commercial comparison with technical and execution control.

Where we add value
You need a repeatable product system—not a one-off marketplace purchase.
Profiles, finishes, glazing, drainage, hardware and packaging must work together.
You need a China-side team to verify the supplier and follow samples and production.
Decision-ready output
We structure dimensions, profiles, glazing, hardware, finishes, performance and documentation requirements.
Candidates are compared on system depth, customization, tooling, quality processes and export experience.
We define what must be evidenced before production, including samples, drawings and agreed acceptance criteria.
Milestones, inspection points, packaging and loading are coordinated through one bilingual desk.
Risks we expose early
Similar-looking systems use different profile thicknesses, alloys, coatings and hardware grades.
Wind, snow-load, water-management or glazing assumptions are not aligned with the target market.
Accessories and replacement parts are not controlled as part of the product system.
Glass protection, labeling and container loading are treated too late in the process.

24H INITIAL PROJECT CHECK
A drawing, product link or current quotation is enough for an initial fit review. We will identify the key gaps and a sensible next step.
