Material Base and Core Application Scenarios
Toilet seat plastic hinges
Made of high-strength engineering plastics, they feature light weight (about 20-30g per piece) and strong plasticity. Currently available in 45mm and 55mm standard sizes, they are compatible with most household toilet seats (especially those made of ABS and PP materials). Due to the insulating and non-heat-conducting properties of plastic, they are more suitable for dry home bathrooms (without long-term water exposure), avoiding the cold touch in winter.
Stainless steel hinges
Crafted from 304 food-grade stainless steel through cold forming technology, with 50mm and 55mm specifications boasting a metallic texture. They excel in deformation resistance (able to withstand 80kg of instantaneous pressure), making them ideal for high-frequency use scenarios such as public restrooms (shopping malls, hotels) and families with pets/children. Especially in humid environments (e.g., toilets near shower areas), they can effectively resist moisture erosion and reduce rust risks.
Comparison of Core Performance Parameters
To more intuitively present the performance differences between the two material hinges, the following table compares key indicators to help you choose based on actual needs:
|
Performance Indicators |
Plastic Hinges |
Stainless Steel Hinges |
|
Load-bearing Capacity |
Suitable for regular use within 30kg; long-term overweight use may cause cracks (especially in low-temperature environments) |
Can withstand 50kg of static pressure for a long time (equivalent to the force transmitted by an adult sitting pressure) and resist 80kg of instantaneous pressure without deformation |
|
Temperature and Corrosion Resistance |
Temperature resistance range: -10℃ to 60℃; long-term contact with hot water above 50℃ may cause softening, and exposure to strong corrosive liquids may lead to surface bulging |
Temperature resistance range: -20℃ to 120℃; no discoloration or rust after contact with hot water or disinfectant (e.g., diluted 84 disinfectant) |
|
Anti-aging Cycle |
Service life of 3-5 years in well-ventilated and dry environments; shortened to 2 years under direct sunlight or long-term humid environments |
Service life of 8-10 years in regular environments; can maintain stable performance for more than 5 years even in humid environments |
Analysis of Installation Convenience and Maintenance Costs
Special note: Ziax provides supporting installation instructions (including hole measurement diagrams), and both types of hinges come with spare screws to reduce the difficulty of self-installation for customers.
Installation method
Both support screw fixation (equipped with M5/M6 stainless steel screws). However, due to their soft texture, plastic hinges can adapt to minor deviations in the pre-drilled holes of the seat cover through slight deformation (compatible with ±1mm error). Stainless steel hinges require strict matching of hole dimensions (error must be controlled within ±0.5mm), so it is recommended to measure accurately with a caliper before installation.
Maintenance costs
If plastic hinges crack or break, the replacement cost per piece is low, and they can be manually disassembled without professional tools. Due to their strong material, stainless steel hinges basically require no daily maintenance. If replacement is needed due to deformation from external impact, the cost per piece is slightly higher, but the replacement frequency is much lower than that of plastic hinges.
Ziax Custom Hinges: Breaking Size Limits for Precise Custom Fit
Limited coverage of standard sizes? Ziax offers full-size customization services, whether you need unconventional sizes like 48mm or 52mm, or special shapes (e.g., with anti-slip patterns or buffer pads).
01
Customization process
Customers provide parameters such as toilet seat hole spacing, installation depth, and load-bearing requirements (photos or hand-drawn sketches can be attached).
02
Customization advantages
Material options: Support for designated plastic grades (e.g., reinforced nylon) or stainless steel models (e.g., 304 or316 stainless steel with stronger corrosion resistance);
03
Process enhancements
Custom plastic hinges can be added with antibacterial additives, and custom stainless steel hinges can undergo brushed/mirror polishing;
Scenario-Based Adaptation Recommendations: Helping You Choose Precisely
Public places (humid, high-frequency use)
50mm/55mm stainless steel hinges are the first choice, as they can withstand wear from multiple users and reduce the trouble of frequent replacement.
Public places (humid, high-frequency use)
50mm/55mm stainless steel hinges are the first choice, as they can withstand wear from multiple users and reduce the trouble of frequent replacement.
Small-sized bathrooms (compact space)
Custom ultra-thin stainless steel hinges (thickness can be reduced to 3mm) are recommended to save installation space;
Smart toilet seat adaptation
Custom plastic hinges with silicone buffer pads can be selected to reduce noise when the seat cover is closed.
