The Barrel Hinge 1250.4.11000 by Vinahardware is a durable, precision-machined hinge designed for heavy-duty steel doors, gates, fences, and industrial enclosures. Made from solid round steel bar, this hinge provides superior strength, smooth operation, and long service life even in demanding outdoor environments.
Construction & Material
Each hinge is manufactured from high-grade solid mild steel or optional alloy steel, machined with precision CNC turning and fitting tolerances to ensure reliable rotation without play. The inner joint is designed with a central pivot pin and a sleeve housing, allowing easy welding onto both door and frame sides. The surface can be treated by galvanizing, black oxide coating, or powder coating depending on the installation environment and customer request.
