Wind and snow performance cannot be judged from a product name alone. The same pergola family can behave differently when its span, roof area, post layout, anchoring and local exposure change.
Start with the Ordered Configuration
Overall dimensions and module layout
Record width, projection, height and whether the roof is freestanding, wall-mounted or connected to another module. Larger spans and combined structures change the loads carried by beams, louvers and posts.
Roof type and open-area behavior
Closed louvers, fixed screens, retractable covers and side panels do not expose a structure to weather in the same way. Note which accessories remain installed during wind or snow conditions and how the roof is intended to operate.
Post positions and connections
Post spacing, corner conditions, beam joints and base plates should be specified on the approved drawings. A strong profile can still underperform if the connection or base detail does not match the site.
Review Exposure and Anchoring Together
Ask the project team to record coastal exposure, open terrain, nearby buildings, roof height, snow accumulation risk and the finished floor condition. Anchoring must then be coordinated with the substrate, embedment, edge distances and any drainage or services below the slab.
Evidence to Request Before Production
| Question | Evidence to request |
|---|---|
| What exact size is being reviewed? | Dimensioned plan, elevations and a clear module schedule. |
| Which weather assumptions apply? | Site exposure, wind zone, snow condition and any local code input. |
| How is the frame anchored? | Base-plate, fastener and substrate detail coordinated with the site. |
| What accessories are included? | Side screens, fixed panels, lighting and other elements that affect exposure. |
Keep Claims Within Their Scope
Test references and engineering guidance can support a purchasing decision, but they should stay tied to the relevant model and configuration. For the intended layout, connect the 225 Series product view with the factory and quality evidence, then confirm any local engineering requirements before production.
