4‑Lite Horizontal Matte Frosted Glass Hinged Door, Slim Black Metal Frame Interior Swing Door with Integrated Lock‑Handle Module

For private spaces such as bedrooms, bathrooms and home offices that demand reliable privacy together with daylight transmission, this 4‑lite matte frosted glass hinged swing door is a practical and stylish solution. Separated into four equal horizontal sections, each lite uses smooth uniform matte frosted glass, surrounded by ultra‑slim black welded metal frame. A compact integrated lock‑handle assembly is embedded on the door leaf, eliminating messy separate hardware and delivering a neat finished look. This door is widely applied in master bedrooms, ensuite bathrooms and private study rooms in modern residences and boutique light‑commercial projects.

The perimeter frame, horizontal muntins and lock‑handle base are precision‑welded high‑grade metal treated with premium matte‑black powder coating. The coating provides strong resistance against daily scratches, fingerprints and ambient moisture, performing steadily even in bathroom‑adjacent humid environments. All welding intersections are fully reinforced to cope with frequent opening‑closing cycles, effectively preventing muntin loosening, frame distortion and glass displacement. The embedded lock‑handle module merges seamlessly with the metal frame design, keeping the door’s clean linear aesthetic intact.

Smooth matte frosted glass forms the core functional advantage of this product. Different from rippled or reeded textured glass that creates visual patterns, this plain frosted surface produces even soft light diffusion. It blocks sharp outlines and interior details completely, so people outside cannot see figures or objects inside the room, while natural light can still pass through to keep the space bright. For diverse project needs, designers can select alternative glass options: clear glass for full visibility, smoked tinted glass for moody low‑light atmosphere, or upgrade to tempered safety glass to meet commercial building‑code standards, while retaining the orderly four‑lite horizontal grid structure.

As a lock‑equipped hinged swing‑style interior door, it adapts to conventional door frame installations. It is an ideal choice when there is insufficient side‑wall area to fit barn‑door sliding tracks. Inward‑swing or outward‑swing direction can be confirmed according to room layout and furniture placement. Matching door frames and heavy‑duty hinges are available as supporting accessories for one‑stop ordering. Qualified installers can finish assembly following standard interior‑door installation workflows.
