Stainless Steel Moisture-Proof Sealed Door

Steel moisture-proof airtight doors and stainless steel moisture-proof airtight doors are two common types of moisture-proof airtight doors. The following is a detailed introduction to them:

Steel Moisture-Proof Airtight Door

• Material and Construction: Typically made of high-quality steel as the primary material, such as cold-rolled steel plates. The door leaf is generally welded from flat steel plates, well-shaped rib plates, and ring beams. The door frame is a combined frame component made of channel steel and I-beam. The tightening device uses wedge-shaped sliders for wedging, and the door pivot is supported by rolling bearings.

• Performance Characteristics:

  • Excellent Moisture-Proof Performance: Through special sealing design and treatment, such as EPDM sealing strips embedded around the door leaf and a pressing mechanism on the inner side of the door leaf, it effectively isolates external humid air, maintains indoor dryness, and prevents stored items from becoming damp or moldy.

  • High Strength and Rigidity: The sturdy nature of steel gives the steel moisture-proof airtight door good impact resistance, enabling it to withstand certain external impacts while ensuring the door's stability during long-term use without deformation.

  • Thermal Insulation Performance: Although steel itself has certain thermal conductivity, reasonable structural design and the addition of insulation materials can improve its thermal insulation effect to some extent, reducing heat transfer between indoors and outdoors, thereby achieving energy savings.

  • Sound Insulation Effect: The multi-layer structure and sealing performance of the steel moisture-proof airtight door provide good sound insulation, effectively blocking external noise and creating a quiet indoor environment.

  • Fire Resistance: It can be designed and manufactured according to relevant standards, offering good fire resistance. In the event of a fire, it can effectively block the spread of flames, buying time for evacuation and firefighting.

• Application Scenarios: Suitable for places with high environmental humidity requirements, such as basements, warehouses, laboratories, food processing workshops, cold storage, power distribution rooms, pharmaceutical warehouses, and wine cellars. It effectively protects indoor items from humid air erosion while meeting the requirements for fire resistance, theft prevention, and other performance needs in these places.

• Stainless Steel Moisture-Proof Airtight Door

• • Material and Construction: The primary material is stainless steel, commonly including 201 stainless steel, 304 stainless steel, and 316 stainless steel. Among these, 304 stainless steel offers good overall performance, while 316 stainless steel has superior corrosion resistance. Its structure is similar to that of steel moisture-proof airtight doors, but due to the characteristics of stainless steel, some design details may differ, such as surface treatment processes.

  • Performance Characteristics:

    • Excellent Rust and Corrosion Resistance: Stainless steel itself has strong corrosion resistance, allowing it to be used for extended periods in harsh environments such as high humidity and high salinity without rusting. This effectively prevents the door from being corroded and damaged, extending its service life.

    • Good Moisture-Proof Sealing Performance: By installing high-quality sealing strips, such as EPDM sealing strips, between the door frame and door leaf, combined with a tight structural design, it achieves excellent sealing effects, preventing external humid air and moisture from entering the indoor space and maintaining dryness.

    • High Strength and Toughness: Stainless steel not only has good corrosion resistance but also high strength and toughness, enabling it to resist external impacts and deformation, ensuring the door's stability and safety.

    • Aesthetic and Elegant Appearance: The smooth and fine surface of stainless steel has a unique metallic luster, requiring no additional surface coating to present an attractive appearance. It is easy to clean and maintain, meeting the aesthetic requirements for doors in various settings.

    • Easy Cleaning and Maintenance: The stainless steel surface is not prone to dust and stains. It can be restored to its shine simply by wiping with water or a mild cleaner, making daily maintenance very convenient.

  • Application Scenarios: Due to its excellent rust and corrosion resistance, stainless steel moisture-proof airtight doors are particularly suitable for harsh environments with high humidity, high salinity, and high moisture levels, such as coastal facilities, basements, pools, wastewater treatment plants, warehouses in chemical plants, pharmaceutical warehouses, and food processing plants. They effectively protect indoor environments and items from humid and corrosive gases.

  • Price Range: The price is relatively high, typically ranging from around 1,500 RMB to 5,000 RMB or even higher. For example, a 304 stainless steel moisture-proof airtight door with dimensions of approximately 1000mm*2100mm may cost between 3,000 RMB and 5,000 RMB. Larger doors made of 316 stainless steel or those manufactured with special processes may exceed 5,000 RMB.
