Heavy Duty Stainless Steel Bonded Sealing Washers With EPDM For Outdoor Use

Bonded sealing washers are essential components in various industries, particularly roofing and construction, where durability, reliability, and efficiency are key requirements. These washers are specifically designed for outdoor applications, featuring a robust combination of A2 stainless steel and grey EPDM rubber. This article highlights the benefits and applications of these washers, emphasizing their utility in challenging environments.
Bonded Sealing Washers
Bonded sealing washers consist of a metal washer, typically made of A2 stainless steel, bonded to a layer of durable EPDM rubber on one side. This innovative combination provides dual functionality: the stainless steel offers strength and resistance to corrosion, while the EPDM rubber creates an effective seal against water, dust, and vibrations.
Key Features and Benefits
Durability in Outdoor Conditions
Stainless Steel Strength: 
The A2 stainless steel ensures excellent resistance to rust and corrosion, making these washers suitable for long-term outdoor use.
EPDM Rubber Sealing: 
EPDM is known for its outstanding weather resistance, tolerating exposure to UV rays, ozone, and extreme temperatures without degrading. This makes it an ideal choice for applications exposed to the elements.
Efficient Installation
Bonded sealing washers simplify the installation process. By combining metal and rubber in one unit, they eliminate the need for separate washers, saving time and reducing complexity during assembly.
Noise and Vibration Reduction
The EPDM layer absorbs vibrations and minimizes noise, making these washers an excellent choice for applications where vibration-induced damage or noise pollution is a concern.
Stress Distribution for Fragile Materials
When fastening delicate materials like Perspex or glass, the EPDM layer evenly distributes the load, reducing stress points and lowering the risk of cracking. This feature makes these washers particularly useful in applications requiring both functionality and material preservation.
Applications of Bonded Sealing Washers
Roofing Industry
Widely used in metal roofing systems to seal fasteners and prevent water ingress. Their corrosion resistance and sealing capabilities make them ideal for maintaining roof integrity in harsh environments.
General Construction
Perfect for sealing joints in outdoor structures, protecting against weather damage, and ensuring the durability of fastened assemblies.
Glazing and Sheet Fastening
Suitable for fastening Perspex, glass, or other brittle sheet materials where controlled pressure is essential to avoid damage.
Noise-Sensitive Installations
Applications requiring reduced vibration noise, such as HVAC systems or machinery, benefit from the noise-dampening properties of the bonded EPDM rubber.
Conclusion
Heavy-duty bonded sealing washers with EPDM rubber are a versatile and reliable solution for outdoor construction and industrial applications. Combining the corrosion resistance of A2 stainless steel with the durability of EPDM rubber, these washers ensure long-lasting performance, ease of installation, and protection for delicate materials. Whether used in roofing, construction, or glazing, these washers provide an efficient and effective way to enhance the resilience and functionality of any project.
