The Contemporary Fire Door is a steel single-leaf fire door product that deeply integrates modern architectural aesthetics with structured fire protection performance. It is designed for building scenarios with high demands for fire safety, spatial order, and facade consistency. This product utilizes a minimalist three-dimensional linear design language, employing clear and restrained three-dimensional lines on the door panel surface. This ensures that the fire door, while meeting regulatory requirements, is no longer merely a functional appendage in the space, but an integral part of the building's facade system. The door panel is made of formed steel plate material, ensuring fire resistance while also providing impact resistance and dimensional stability under long-term use, preventing deformation due to temperature changes or frequent opening. Overall, the Contemporary Fire Door is not simply a functional door body that emphasizes fire resistance indicators; it is a fire door solution that strikes a balance between safety regulations, structural reliability, and modern architectural expression, suitable for project-based buildings with clear requirements for both quality and compliance.

1. Fire Resistance and Stability
The door leaf of the Contemporary Fire Door features a monolithic structure design with a thickness of 80–100mm, making it easier to maintain structural integrity and thermal insulation continuity during fire resistance testing. According to common fire door testing logic, the core evaluation includes two aspects: integrity and thermal insulation. The door body must remain intact without penetration or collapse during the ≥90-minute fire resistance phase, and the temperature rise on the unexposed side must not exceed the standard limit. The steel door panel and internal structure work together to reduce warping and gap expansion caused by high temperatures, thereby reducing the risk of smoke and heat penetration. The increased door leaf thickness also helps to lengthen the heat conduction path, making fire resistance stability more controllable, suitable for projects with higher requirements for the reliability of fire compartmentation.
2. Steel Plate Strength
The door panel of the Contemporary Fire Door uses formed steel plate material. The material strength indicators can be controlled according to common structural steel reference values, with tensile strength ≥270MPa and yield strength ≥210MPa, meeting the stiffness requirements of the door body under the combined effects of external impact and high-temperature softening. The steel plate thickness and reinforcing structure work together to reduce the probability of local dents and edge curling on the door surface, maintaining stable door gaps and preventing misalignment of the lock bolt and strike plate. Compared with thinner door bodies, the steel structure provides more stable rebound and deformation control under stress, preventing sagging and twisting during long-term use, and making it easier to maintain the flatness and locking accuracy of the door leaf within verifiable limits.
3. Structural Thickness
The 80–100mm door leaf thickness is not only a size parameter but also directly determines the space available for the internal fire-resistant layer and support structure. A thicker door body can accommodate a more complete layer of insulation material and reinforcing framework, resulting in a more even stress distribution on the fire-exposed side after heating, reducing the risk of through cracks and edge cracking. Increased thickness also improves the bending stiffness of the door leaf, reducing deflection changes under high-temperature conditions, and making the fit between the door body and door frame more stable. According to engineering inspection practices, the diagonal difference and flatness of the Contemporary Fire Door's door leaf usually need to be controlled within the allowable installation tolerance. The thicker structure makes it easier to consistently meet this requirement, reducing performance fluctuations caused by on-site adjustments.
4. Hardware Durability
Contemporary fire doors are equipped with mechanical locking systems and visible hinges, emphasizing reliability and maintainability under high-frequency opening and closing conditions. Hardware durability is typically measured by opening and closing cycle tests, with common requirements specifying that the lock remains smooth, the hinges show no significant loosening, and the door leaf sag remains within a controllable range after at least 200,000 cycles. Mechanical lock structures rely more on physical metal transmission components than electronic control systems, resulting in more predictable failure modes and facilitating regular inspections. Visible hinges allow maintenance personnel to directly observe wear and tightness, making it easier to retighten according to torque standards, reducing problems caused by increased hinge clearance leading to excessive door gaps and lock point misalignment, thus ensuring long-term reliable closure.
5. Size Adaptability
The standard size of 2050×960mm facilitates matching with common building opening modules, while also supporting custom sizes to accommodate different wall thicknesses and opening deviations. In custom manufacturing, the key is to control the size deviation of the door leaf and frame within the installable range, for example, maintaining processing accuracy within ±1.5mm, and ensuring the straightness of the four sides of the door leaf and the squareness of the corners are verifiable. Size stability directly affects the control of the fire door's closing gap; an excessively large gap increases the probability of smoke penetration, while an excessively small gap leads to increased friction and opening/closing resistance. Through strict control of cutting, bending, and assembly benchmarks, the gap after installation can be more uniform, reducing the uncertainty caused by on-site cutting or secondary gap filling on overall performance.
