Importance of washers for roofing screws
As an ISO9001-2008 certified company, Yuyao Cili Machinery Co., Ltd. is well aware of the core role of screws and washers in ensuring the stability and waterproof performance of the roofing system.
Sealing performance
Washers play a key sealing role in the roofing screw system. They are located between the screws and the roofing material, forming a closed contact surface to prevent the intrusion of moisture, dust and other environmental factors. Good sealing not only prevents rainwater from leaking, but also protects the roof structure from environmental erosion. The material, design and installation quality of the washer directly affect the effectiveness of its sealing performance.
Pressure dispersion
Another important function of the washer is to disperse the pressure applied by the screw. Roofing materials are usually fragile, and the concentrated pressure of the screws may cause deformation or damage to the material. Washers protect the integrity of the roofing material and extend its service life by dispersing pressure and reducing local stress.
Preventing water leaks
High-quality washers can effectively prevent moisture from penetrating through the screw holes and prevent water leaks. This not only avoids moisture and rot in the roof structure, but also maintains the overall stability of the roof system. Leaks, if not addressed promptly, can cause serious structural damage and increase maintenance costs.
Gaskets age over time. Rubber or plastic gaskets can dry out, harden, or crack when exposed to UV rays, humidity, and temperature changes. Aged gaskets fail to provide an effective seal, increasing the risk of leaks and other problems. Yuyao Cili Machinery Co., Ltd. recognizes this and is committed to using durable materials and advanced production processes to extend the life of gaskets.
During installation or daily use, gaskets can suffer physical damage, such as tearing or deformation. This can be caused by improper installation methods, over-tightening screws, or severe weather conditions. Physical damage can cause gaskets to fail to seal effectively, thus affecting the waterproof performance of the roof.
Chemicals in the environment (such as acid rain, industrial pollution) can corrode gasket materials and reduce their sealing performance. Chemical corrosion not only reduces the life of the gasket, but can also cause structural problems in the roof system.
Regularly checking the condition of the gasket is an essential measure to maintain its performance. A comprehensive inspection is recommended once a year, especially after extreme weather conditions. The inspection includes the gasket's appearance, elasticity, and whether there are cracks or aging. Yuyao Cili Machinery Co., Ltd.'s technical team recommends that users pay special attention to the gasket's sealing effect and integrity during inspection.
Regular cleaning of the gasket can prevent the accumulation of dirt and impurities, which may affect the gasket's sealing performance. Use a mild detergent and a soft brush for cleaning, and avoid using strong acid or alkaline cleaners. Yuyao Cili Machinery Co., Ltd. recommends using professional cleaning tools and methods to ensure the maintenance quality of the gasket.
