Thank you for raising this important safety concern. The sharp edges you encountered in the previous factory's trash cans are a known hazard, especially during liner changes or when cleaning the bin. At our facility, we treat this as a critical design priority. Every trash can we produce features fully rolled rims on both the top edge and any internal openings, such as access slots or handles. This manufacturing process folds the metal or plastic edge back onto itself, creating a smooth, rounded surface that is completely free of burrs or sharp cuts. Additionally, we perform a 100% visual and tactile inspection on every unit, using a specialized gauge to verify that no exposed edge exceeds a safe radius. Our internal walls are also deburred and polished to prevent any snagging or finger injuries. If you require extra protection, we offer an optional protective rim strip made of food-grade silicone. We are confident these features meet or exceed industry safety standards, and we welcome you to request a sample to feel the difference yourself. Your team's safety is just as important to us as the durability of our products.
