In large commercial buildings, due to their complex structures, strict construction standards and diverse environmental requirements, some special types of drywall screws are usually used. These special types of screws can meet special requirements such as high strength, corrosion resistance, fire resistance, and earthquake resistance. The following are several common special types of drywall screws and their application scenarios:
1. Self-drilling drywall screws
Features: Self-drilling screws have sharp drill bits and can be installed directly without pre-drilling, which greatly improves construction efficiency.
Application scenarios: Suitable for occasions that require quick installation, such as internal partitions and ceiling installations in large commercial buildings.
Advantages: Save time, reduce labor intensity, and are especially suitable for large-area gypsum board installations.
2. Moisture-Resistant Screws
Features: The special moisture-proof coating can effectively prevent the screws from rusting in a humid environment.
Application scenarios: Commonly used in humid environments such as basements, bathrooms, kitchens, and water treatment areas in commercial buildings.
Advantages: Extend service life and ensure long-term stability of wall structures.
3. High-Strength Gypsum Board Screws
Features: Made of high-strength steel, it can withstand greater tension and shear force.
Application scenarios: Used in situations where high-strength fixation is required, such as the installation of load-bearing walls and hanging equipment (such as lamps and air conditioners) in large commercial buildings.
Advantages: Provide higher structural safety and are suitable for high-load building environments.
4. Fire-Resistant Screws
Features: After special treatment, it can withstand high temperatures and maintain structural integrity, meeting fire protection standards.
Application scenarios: Used for wall installation in fire-proof partitions, such as firewalls and evacuation passages in large shopping malls and office buildings.
Advantages: In the event of a fire, it can effectively prevent the spread of fire and ensure the safety of personnel.
5. Earthquake-Resistant Screws
Features: Designed to maintain structural stability in extreme situations such as earthquakes, with good vibration resistance.
Application scenarios: Suitable for commercial buildings in earthquake-prone areas, such as hospitals, schools, and large shopping malls.
Advantages: When an earthquake occurs, it can reduce the risk of wall cracking and falling off, ensuring the safety of the building structure.
6. Stainless Steel Screws
Features: Made of stainless steel, it has extremely high corrosion resistance and durability.
Application scenarios: Commonly used in outdoor buildings, seaside buildings or humid environments, such as the facades and roofs of commercial buildings.
Advantages: It can maintain long-term stability in harsh environments and reduce maintenance costs.
7. Washer-Head Screws
Features: The screw head has a washer, which can better disperse pressure and prevent damage to the gypsum board surface.
Application scenarios: Suitable for commercial buildings that require beautiful surfaces, such as shopping malls and public areas of hotels.
Advantages: Reduce dents and damage on the surface of the gypsum board, making it easier to decorate.
8. Expanding Screws
Features: The screws expand during installation, further enhancing the fixing effect.
Application scenarios: Used in situations where additional fixing strength is required, such as installing large billboards, hanging equipment, etc.
Advantages: Provides higher fixing strength, suitable for high-load commercial building environments.
