Custom Pergola 2x4m Supplier & Factories

Yes, our engineering team regularly configures the 2x4m model as a wall-mounted system where either the 4m side or 2m side anchors directly into structural concrete or steel building columns. In a wall-mounted configuration, the wall-side posts are removed, relying on custom extruded wall-mount brackets with concealed expansion bolts and industrial silicone sealant barriers. This retains full integrated gutter drainage while lowering overall hardware costs and eliminating obstacles on terrace footpaths.

Each louver features dual-channel water troughs along its profile edge. When closed, water flows along the louver slope into primary internal perimeter gutters incorporated directly within the horizontal carrier beams. From there, water directs to internal downspouts integrated inside the corner upright posts (typically 120x120mm or 150x150mm profiles). Our 2x4m systems deliver a certified water discharge rate exceeding 100 liters per hour per square meter, easily handling extreme tropical or monsoon downpours without perimeter spillage.

For standard profile configurations with custom branding (including silk-screened motor enclosures, laser-etched post badges, branded export crating, and white-label installation manuals), our typical minimum order threshold is a mixed 20ft container (approximately 18–24 pergola units). For complete bespoke aluminum die extrusion designs, the minimum run per custom die profile is 1 metric ton of billet aluminum.

Our 2x4m models are pre-routed during 5-axis CNC machining to incorporate concealed side-track recesses inside the upright structural posts. This allows the zipper screen channels to sit entirely flush with the post geometry, creating an airtight, insect-proof, and windproof seal rated to withstand 80 km/h buffeting winds. Screen cassettes mount invisibly beneath the carrier beam, ensuring clean architectural sightlines.

For seaside installations located within 500 meters of the coastline, we recommend our specialized AkzoNobel Interpon D2525 super-durable powder coat with pre-anodized or zirconium chemical conversion pre-treatments. This treatment provides a 10 to 15-year guarantee against peeling, blistering, and corrosion under continuous salt fog testing according to ASTM B117 standards.
