At our trash can factory, we understand that hinges are one of the most stressed components of any waste container—especially in commercial or industrial environments where bins are opened, closed, and dumped repeatedly. To directly answer your question: The warranty on the hinges of our trash cans is a 5-year limited warranty from the date of original purchase. This warranty covers any manufacturing defects in materials or workmanship, including issues such as hinge cracking, corrosion under normal use, or failure of the hinge pin mechanism. It does not cover damage from deliberate abuse, improper installation, or modification of the hinge assembly. For residential models, the same 5-year hinge warranty applies, while our heavy-duty commercial series may offer an extended 7-year warranty for the hinge system due to our reinforced stainless steel and galvanized steel construction. We also provide free replacement parts within the warranty period, but labor costs for installation are not included unless the unit was factory-installed. To make a claim, simply contact our customer support with your purchase receipt and a photo of the defect. We take hinge reliability seriously—our internal tests simulate over 50,000 open-close cycles, ensuring your trash can hinges last well beyond the warranty term.
