BEST INTERIOR STEEL DOOR SUPPLIER
What is Interior Steel Door
There are many terms for steel interior doors, such as steel-wood interior doors, American-style steel doors, and so forth. Essentially, they are all the same type of door, which is primarily popular in Canada, the United States, and Central and South America. The door panel surface is made of steel, while the interior structure is wooden. The filling material inside can vary, including options like honeycomb paper, asbestos, PU foam, etc. The door frame can be made of steel or wood. The primary color is white, but we can also provide other colors, such as black or walnut. For more details, please continue reading below.
Interior Steel Door Structure
Steel-wood interior doors, sometimes referred to as American-style steel doors or hollow steel doors, typically feature a white color scheme. The door panel’s surface is made of steel and is painted white. The interior can be filled with materials such as honeycomb paper, polyurethane, or Polystyrene. The internal frame of the door panel is wooden, and usually, the wood around the edges of the door panel extends 3 millimeters beyond the panel itself to accommodate hinge holes.
Door panels generally use round handle locks. The design mainly features a six-grid pattern. Of course, Tongyu Industry offers many other styles for you to choose from, and you can also have glass inserts in the middle of the door panel.

High-Grade Materials
Galvanized steel skin
Corrosion Resistance: The galvanized steel plate has a layer of zinc on its surface, which effectively prevents the iron door from rusting and corrosion, extending its service life.
High Strength: The strength of galvanized steel plate is higher than that of ordinary steel plate, allowing it to withstand greater impacts.
Aesthetic Appeal: The surface of the galvanized steel plate is smooth, which can be coated with various colors, offering good decorativeness.
Good Workability: Galvanized steel plates can be processed by cutting, welding, bending, etc., meeting the needs of different shapes and sizes.
Advanced pressing equipment.
Advanced pressing equipment ensures that polyurethane is filled 100% into the door slab, guaranteeing there are no air pockets inside the door slab. This ensures the flatness of the door slab and prevents it from collapsing, thereby guaranteeing the service life of the door.
