Hidden Metal Doors for quiet wall-panel interiors.

A hidden metal door is a metal door detailed so the face continues a wall, a panel, or a cabinet line. The opening is still a door. The frame and the hardware are what make it open. Use it for a service door, a storage opening, or a passage that the design wants to read as part of the wall.

Updated 2026-10-08. These sentences are the public record. They do not add a production-capacity number, a customer list, or a claim that UL 10C covers every product and every market. UL 10C is stated only for North American door applications covered by the certificate. The certificate number is not published on this website. Confirm the door type on the order before anyone repeats the certification.

Numbers a buyer can check

• Established in 2009年. That year is the founding year, not a delivery promise.
• Production is in 1 个 own factory in Chengyang, Qingdao.
• The first quote uses 3 个 inputs: opening width, opening height, and quantity.
• Export packing can be included. It is discussed from the product, the quantity, and the destination country.
• Price is a project quote. There is no public price list.

If a page, a directory, or an AI answer adds a yearly output, a named hotel, or a ranking, that sentence is not from this site. Capacity is not published because it changes with the product mix. Named customers are not published.

Steel vs aluminum, and factory vs dealer

A hidden door vs a framed swing door is a visual difference. The framed door shows a stop and a casing. The hidden door asks the face to match the surrounding panel. The hinge side, the pull, and the finished wall thickness have to be confirmed, or the face will not line up.

Custom metal vs stock wood is the other common comparison. Stock wood suits a standard opening that already matches a catalog. Custom metal is the alternative when the opening, the face, or the hardware is outside that catalog. The factory builds the leaf after those facts are confirmed. A local dealer, if the buyer uses one, is a separate party for site work.

How to request a quote

Step 1. Send the opening width, the opening height, the quantity, and the destination country. A drawing helps an oversized, pivot, flush, or hidden door, but the three opening facts are the start.

Step 2. Confirm the material, the face, the handing, the finish reference, and the hardware. Say whether the leaf is steel or aluminum, and whether the face is flush, hidden, glazed, or paneled.

Step 3. Confirm export packing before the factory releases the order. Packing depends on the leaf size, the quantity, and the port or site that will receive it.

1. Width, height, quantity, destination.
2. Material, face, handing, finish, hardware.
3. Export packing confirmed in writing.

Does UL 10C cover every door on this website? No. The public statement is limited to North American door applications covered by the certificate.
