During the use of safety hasps, especially after a long period of time, some rusting may occur. Let’s take a look at why safety hasps can rust:
- Material quality issues caused by cost control
Due to cost control and the pursuit of profit, material selection has become more complicated under price competition. Some materials come from unreliable sources with unpredictable quality, which leads to a decline in the quality of processed parts. For example, non-metallic shaft sleeves or stainless steel tubes may contain higher moisture or sulfur content, which weakens the material’s natural rust-resistance. This is one of the major causes of rusting. - Inadequate rust-prevention treatment during manufacturing
As technology advances and product requirements increase, competition in the hardware industry is becoming more intense. Many companies enter the market rapidly, resulting in mixed and inconsistent product quality. To reduce costs and increase profits, some manufacturers compromise on essential product and service standards. As a result, the rust-preventive lubricants, cleaning gasoline, or other coatings used during the processing of housing hardware and components may not meet the original technical specifications. - Poor workmanship from small-scale processing enterprises
Small workshops can negatively affect industry development because they lack proper production environments. To cut costs, they often use lower-quality molds, outdated die-casting equipment, and unskilled technicians with insufficient experience. These conditions lead to poor grinding, polishing, and rust-prevention treatments. - Rushed production and neglected processing procedures
In the manufacturing industry, competition often involves both speed and quality. During peak production periods, required rust-proofing steps—such as cleaning, coating, or sealing—may be rushed or ignored. This compromises the production process and product appearance, causing hidden quality issues that later result in rust in normal use. - Long-term storage conditions
Safety hasps are typically mass-produced, and companies often store large quantities. Long-term storage is therefore unavoidable. Some hardware suppliers focus only on the outer packaging appearance but overlook proper long-term storage protection. Poor sealing, moisture intrusion, and oxidation inside the packaging can all cause the hasps to rust even before installation, leading to avoidable quality problems.
