Что такое стальной дверной лист?

А steel door sheet refers to a pre-cut, pre-finished piece of metal—usually galvanized, cold-rolled, or stainless steel—that is used as the outer skin of a steel door. These sheets are formed through precision stamping or pressing and can be designed with paneling, grooves, embossing, or flush finishes.

Steel door sheets are typically bonded to a core material, such as honeycomb, steel reinforcements, polyurethane foam, or mineral board, depending on the application (e.g., fire-rated, acoustic, thermal, or security).

Door Panel Manufacturing: Key Capabilities

A leading door panel manufacturer интегрирует cutting-edge production technologies и advanced materials to deliver superior products. Core competencies include:

1. Sheet Metal Fabrication

С использованием high-precision CNC machines, laser cutters, and automated punches, manufacturers cut and form door panels to exact specifications. Common sheet thicknesses range from 0.5 mm to 2.0 mm, в зависимости от области применения.

2. Stamping and Embossing

Manufacturers use hydraulic presses and die-stamping machines to create:

• Decorative designs (e.g., 4-panel, 6-panel, arched)

• Ventilation patterns (louvered designs)

• Security grooves and reinforcements

3. Powder Coating and Surface Finishing

Steel door sheets are coated using electrostatic powder coating to provide:

• Устойчивость к коррозии

• Scratch and impact protection
