Key Advantages
Corrosion-resistant and rust-proof
The base material is 304/316 stainless steel, which is resistant to rain, moisture, acid and alkali mist, and salt spray from seawater. It does not rust even after long-term use, significantly reducing the cost of later maintenance and replacement. The 316 model is additionally resistant to chloride ion corrosion.
High and low temperature stability
The mechanical properties do not crack or deform under high and low temperature environments. High-temperature cookers, cold chain equipment, and outdoor severe cold scenarios can all be stably fastened without the problem of loosening caused by thermal expansion and contraction of ordinary carbon steel screws.
Non-toxic and environmentally friendly, food-grade
304 stainless steel complies with food contact safety standards, does not release heavy metals, and can be used for kitchenware, medical devices, food processing equipment, and drinking water equipment assembly, ensuring safety and compliance.
