Beautiful, Practical & Purification-Grade: The Steel One-and-Half Leaf Door
The Steel One-and-Half Leaf Door is a special type of double door, composed of a narrower leaf (the sub door) and a wider leaf (the main door). In daily use, only the main door is operated while the sub door remains closed; when needed, both leaves can be fully opened — delivering both beauty and practicality. Built to cleanroom standards, the door frame and panel are manufactured from high-quality galvanized steel plate with powder coating for superior corrosion resistance. High-grade sealing strips on three sides, combined with a lifting drop-down sweep seal at the bottom, provide strong airtightness that effectively guarantees indoor purification. The 50 mm honeycomb-core panel fully meets cleanroom requirements, making this door widely applicable across hospitals, food, and electronics.

Special Double Door — Sub Leaf + Main Leaf, Beautiful & Practical
- A special double door composed of a narrower sub door and a wider main door. In daily use, only the main door is operated with the sub door normally closed; when needed, both leaves can be fully opened — beautiful and practical for every situation.
Galvanized Steel + Powder Coating — Superior Corrosion Resistance
- The door frame and panel are manufactured from high-quality galvanized steel plate with powder coating — providing superior corrosion resistance that endures humidity, chemicals, and frequent disinfection.
Three-Side Seals + Lifting Drop-Down Sweep — Strong Airtightness
- High-grade sealing strips on three sides, with a lifting drop-down sweep seal at the bottom — delivering strong airtightness that effectively guarantees the indoor purification effect, preventing drafts, dust, and airborne particles from crossing the threshold.
50 mm Honeycomb-Core Panel — Fully Purification Compliant
- The door panel is 50 mm thick with paper honeycomb or aluminum honeycomb core filling — fully meeting cleanroom requirements with structural rigidity, flatness, and lightweight construction.
Dual-Mode Access — Daily Use Plus Full-Width Opening on Demand
- The wide main leaf serves as a standard personnel door for daily traffic; opening the sub leaf provides full-width passage for gurneys, trolleys, and equipment — one door delivering both everyday convenience and occasional wide access.
Widely Applicable — Hospitals, Pharma, Food & Electronics
- Widely applicable to hospitals, food, electronics, and other clean and hygienic sectors — where corrosion resistance and purification compliance are essential.
High-Quality Hardware — Beautiful, Reliable, Long-Lasting
- High-quality hardware fittings ensure product quality, extend the product's service life, and make the door look beautiful, elegant, and highly usable.
