| 1 | Aluminum structure | Extruded aluminum posts, beams, and louver components are widely used for outdoor pergolas. | Aluminum is relatively lightweight and can be finished for outdoor exposure. | Request alloy and temper details, section drawings, wall thicknesses, and material documentation for the quoted model. |
| 2 | Adjustable louvers | Roof blades can be adjusted to control sunlight and airflow; operation may be manual or motorized. | Adjustability lets users change the roof setting as weather and shading needs change. | Confirm the adjustment range, operating method, blade profile, and whether the roof is designed to close fully. |
| 3 | Motor and controls | Motorized systems may use a remote control, wall switch, or compatible smart-control options. | Control options affect convenience and integration with the building’s electrical system. | Check motor specifications, voltage and frequency, wiring requirements, control compatibility, warranty, and replacement-part availability. |
| 4 | Rainwater management | Many designs route water from the louvers into gutters and down through posts or designated outlets. | Drainage design can help manage rainwater around the covered area. | Ask for drainage drawings, outlet locations, installation details, and any stated rainfall or drainage-performance limits. |
| 5 | Wind and snow engineering | Structural performance depends on the product configuration, dimensions, anchoring, and installation site. | Local wind and snow conditions can affect safety, permitting, and product selection. | Provide the project location and request applicable load calculations, test reports, and anchoring requirements. Do not assume one rating applies to every size or installation. |
| 6 | Surface finish | Powder-coated finishes are commonly offered, often in a selection of standard or custom colors. | Finish selection influences appearance and resistance to outdoor exposure. | Confirm the coating specification, color reference, pretreatment process, warranty terms, and any supporting test documentation. |
| 7 | Size and project customization | Suppliers may offer different layouts, dimensions, post positions, and connection details. | Customization can help accommodate patios, terraces, and commercial outdoor spaces. | Obtain approved shop drawings and verify maximum dimensions, support locations, tolerances, and any effect on structural performance. |
| 8 | Optional enclosures and accessories | Options may include side screens, lighting, heaters, or other compatible accessories. | Accessories can extend the use of an outdoor area and may need to be coordinated with the roof design. | Confirm compatibility with the selected model, power requirements, installation sequence, and whether accessories are included in the quotation. |
| 9 | Quality and compliance documentation | Documentation varies by supplier and product; project-specific requirements may differ between destination markets. | Clear records help buyers assess product suitability and support local approval processes. | Request model-specific manuals, drawings, test reports, material records, and certificates. Check that documents apply to the exact configuration being purchased. |
| 10 | Export and after-sales support | Export orders may involve protective packaging, international shipping arrangements, installation guidance, and spare parts. | Delivery planning and accessible replacement components can reduce project delays. | Confirm packing details, delivery terms, lead time, installation support, spare-parts process, warranty coverage, and responsibilities for transport and import charges. |
