SHUIDAO

Key Features

• Door Type: Single-leaf flush-panel interior door — hinged, single panel swing (hinge side — left / right hand — please confirm; fire rating — please confirm; acoustic / sound insulation rating — please confirm)
• Door Face: Flush construction with four full-width inlaid horizontal metal strip inlays — the door face is a flat woodgrain panel with four parallel metal strips inlaid flush or proud across the full door width at evenly spaced intervals; the strips divide the door face into five horizontal bands of approximately equal height; the metal inlays are the door’s primary design feature and primary material differentiator within the D86 smart lock range (metal strip material — brushed aluminium / stainless steel / chrome-plated / other — please confirm; strip width and depth — please confirm; flush inlaid or surface-proud — please confirm)
• Metal Strip Layout: Four horizontal strips running full door width — evenly distributed across the door height, creating five approximately equal-height woodgrain bands between and around the strips; the strip spacing places one strip at approximately one-quarter height, one at mid-door (aligning with the smart lock handle zone), one at three-quarter height, and one in the lower quarter; the regularity of the spacing gives the composition a measured, gridded quality (confirm strip count and exact spacing)
• Surface Finish: Dark grey-brown / charcoal-taupe woodgrain — a deep, cool-leaning grey-brown woodgrain with fine vertical straight grain; the tone sits between dark grey, charcoal, and cooled-down brown — cooler and more silvered than the walnut tones of the D8658/D8660 but warmer than the D8657’s near-black wenge; the fine straight vertical grain provides a quiet, non-figuring background that allows the horizontal metal strips to read clearly (finish material — real wood veneer / engineered veneer / PVC woodgrain foil — please confirm; finish options — charcoal grey / dark taupe / slate / custom — please confirm)
• Smart Lock System: Satin gold / warm gold electronic lever lock — the same vertical escutcheon format as the D86 smart lock range: upper card reader / keypad panel with digital interface, lower lever handle; the finish here reads as a warm satin gold — positioned between the bright champagne gold of the D8657/D8658 and the darker antique bronze of the D8659; the satin gold hardware echoes the silver metal strip inlays in its reflectivity while contrasting them in warmth — a deliberate warm-cool metallic pairing (lock type — RFID card / PIN keypad / fingerprint / Bluetooth / combined — please confirm; brand / model — please confirm)
• Architrave / Frame: Plain flat-profile door frame in matching dark grey-brown woodgrain — consistent with the door leaf finish; no moulding; the metal strips do not extend into the frame, terminating cleanly at the door leaf edges
• Core Construction: (solid wood / solid engineered wood / honeycomb core / fire-rated core — please confirm)
• Overall Dimensions: (please confirm W × H × thickness)

Ideal For

Hotel developers, serviced apartment operators, residential developers, and architectural interior designers specifying contemporary doors where material authenticity and inlaid craft detail are explicit design brief requirements. The D8666’s inlaid silver metal strip detailing positions it as the most technically refined model in the SHUIDAO smart lock flush door range — the correct specification for four-star-plus hotel guest room and suite entries, premium serviced apartment corridors, and design-led residential developments where the door finish must communicate quality through material contrast rather than surface colour alone. The warm-cool metallic pairing of silver inlay strips and satin gold lock hardware is an intentional design decision that connects to both the SHUIDAO brushed stainless and brushed gold bathroom fitting ranges, enabling a dual-metal specification strategy that is increasingly common in contemporary luxury hospitality interior design.
