Fireproof Soundproof Doors

Steel firedoor：Our steel fire doors are manufactured in compliance with European Standard EN1634 and American UL standards, and are widely used in most countries and regions worldwide, with a fire resistance rating of up to 3 hours. The door frame, door leaf frame, and door leaf panel are made of steel, while the door leaf is filled with fire-resistant and thermal insulation materials that are non-toxic and harmless to humans. The doors are also equipped with fire-rated hardware components.Both the door frame and door leaf feature an interlocking structure, ensuring a seamless appearance with no visible weld points.  The encased fire seal strip is designed in the middle of the door leaf and embedded into both the door frame and the door leaf, providing a flat surface without protrusions for smooth opening and closing. Thanks to the wide, thick, and centrally positioned seal strip, the door offers excellent sound insulation.  The production process utilizes high-precision production lines, resulting in fire doors with superior alignment, minimal gaps, and outstanding performance. The painted surface of the fire doors exhibits a high-gloss finish, exceptional adhesion, and enhanced corrosion and wear resistance.

Glass Firedoor：Nano-silicon fire-resistant glass is a specialized type of fire-resistant glass manufactured using nano-silicon material technology.  It features a multi-layered glass structure, with nano-silicon fire-resistant fluid injected between the glass layers. The principle of fire resistance and thermal insulation is as follows: when exposed to fire, the glass on the fire-facing side cracks and falls off, allowing the nano-silicon fire-resistant material to come into direct contact with the flames. This causes the material to expand several times, forming a thick insulating layer. The expanded layer primarily consists of silica, which exhibits excellent high-temperature resistance. Due to the thickening effect, it also provides superior thermal insulation.  Available models include three-glass-panel, two-cavity structures with thicknesses of 25mm or 30mm, as well as four-glass-panel, three-cavity structures with a thickness of 35mm. According to the principle of layered effects, more glass layers and cavities result in longer fire resistance durations, which can reach 1 hour, 1.5 hours, 2 hours, or 3 hours of fire resistance and thermal insulation performance.  Additionally, after the nano-silicon fire-resistant glass is injected and sealed, it is baked in a heating furnace for 12 hours. This process causes the injected nano-silicon fire-resistant fluid to crystallize, preventing common issues such as bubbling, discoloration, and reduced light transmittance that are often found in ordinary fluid-injected fire-resistant glass. As a result, it is the preferred choice for fire-resistant glass doors, fire-resistant glass partitions, and curtain wall glass.  Moreover, thanks to the nano-silicon expansion layer and multi-layered structure, this glass fully complies with the new fire door standard's water impact resistance test, making it the most reliable option for vision panels in fire doors in the future.
