Aluminum Ward Doors VS. Galvanized Steel Ward Doors from TSTC
To the hospital ward doors /manual swing doors from TSTC, the mostly used 2 materials are galvanized steel and aluminum . What about the differences between them ? The answers are as below .
1. Aluminum Ward Doors
The aluminum ward doors here are the ones that both leaf panels and door case are aluminum alloy sheets, the detailed structure are as below .
Face panel: 3003 anti-rust aluminum sheet / 5052 aluminum alloy sheet, standard thickness 1.2~1.5 mm.
Door case & extruded profiles: 6063-T5 extruded aluminum alloy profiles .
Inner filling: Aluminum honeycomb core (lightweight and flame retardant) .
Surface finish: Antibacterial polyester electrostatic powder coating, identical to the coating process of galvanized steel doors.
▪ Advantages
Zero rust risk: Top choice for coastal hospitals, dialysis rooms, wards adjacent to restrooms, and high-humidity fever clinics.
Light weight for effortless operation: Aluminum doors are 40% lighter than steel doors of the same dimension.
Superior resistance to disinfectant corrosion: Aluminum base material boasts better chemical stability than steel. Long-term wiping with 84 disinfectant and chlorine-based disinfectants will not erode the substrate.
Non-magnetic and anti-static, suitable for laboratories and wards around radiology departments.
Integrated seamless bending structure with rounded R corners, no dust accumulation dead corners, meeting high hospital infection control standards.
▪ Disadvantages
Inferior impact resistance to galvanized steel: Aluminum is relatively soft and prone to dents under heavy impact from metal hospital trolleys,not recommended for standard multi-patient wards.
Higher cost: 40%~80% more expensive than DC51D+Z powder coated galvanized steel doors of identical specifications.
Limited fire resistance performance: Class A fire rating is hard to achieve; most products only reach Class B1 flame retardant grade.
Dents caused by sharp hard impacts cannot be repaired.
2. Galvanized Steel Medical Doors
▪ Structure
Door leaf: 0.8 ~1.0 mm hot-dip galvanized steel sheet with jointed seamless folding / integrated bending, inner core filled with paper honeycomb, aluminum honeycomb or sound-insulating rock wool.
Door case: 1.2~1.5 mm galvanized steel sheet with antibacterial electrostatic powder coating, wood grain transfer printing or film lamination finish.
▪ Advantages
Best cost performance, top choice for mass hospital construction projects.
Galvanized coating provides rust resistance, tolerates long-term wiping with 84 disinfectant, alcohol and chlorine-containing disinfectants.
High structural strength, resistant to impacts from hospital beds and trolleys, available as Class A fire-rated door.
Moderate overall weight for effortless manual swing operation, maintains shape after hundreds of thousands of opening & closing cycles.
Rich color options, wood grain transfer finish delivers warm texture similar to solid wood doors.
▪ Disadvantages
Cold metallic appearance, extra thick sound insulation wool is required to improve acoustic performance.
Prone to dents under heavy impact from sharp hard objects.
3. Comparison Between Aluminum Ward Doors & Galvanized Steel Ward Doors
| ID | Performance Index | Aluminum (3003/5052) -Powder Coated Surface | Galvanized Steel Doors (DC51D+Z) -Powder Coated Surface |
| 1 | Rust Resistance | Excellent, suitable for humid and coastal environments | Good, rust occurs if base metal is exposed by coating damage |
| 2 | Trolley Impact Resistance | Fair, susceptible to dents | Excellent, ideal for frequent collisions in general wards |
| 3 | Door Leaf Weight | Lightweight, easy manual swinging | Relatively heavy, load bearing relies heavily on hinges |
| 4 | Fire Rating | Only Class B1 flame retardant, Class A rating unachievable | Available in Class A / Class B fire ratings for ward doors |
| 5 | Cost | High | Cost-effective, first choice for large-scale projects |
| 6 | Applicable Zones | High-humidity areas, coastal hospitals, clean isolation areas | General wards, corridors, outpatient departments, primary hospitals |
Note:
To the TSTC hospital ward doors, the thickness of the key materials will be showed as below .
1. Galvanized Steel. The door leaf is galvanized steel plate with thickness 0.8-1mm, the door case is galvanized steel plate with thickness 1.5mm .
2. Aluminum. The door leaf is aluminum plate with thickness 1.2-1.6mm, the door case is aluminum alloy with thickness 4mm .
3. HPL Plate . The door leaf is HPL plate with thickness 1mm +1mm aluminum plate inside.
4. Stainles Steel. The door leaf is stainless steel plate with thickness 1.2mm, the door case is aluminum alloy with thickness ≥1.5mm inside + 1.2mm stainless steel .
