This aluminum alloy bent bracket — also referred to as a curved support arm or special-shaped connecting bracket — is manufactured through precision CNC machining. It is produced from high-quality aluminum alloy raw material and finished with an anodizing surface treatment. Multiple threaded holes are pre-machined into the base for quick assembly and locking.
As a non-standard custom hardware fitting, this curved bracket is widely used for positioning, support, and connection in automation equipment, machinery, fixtures, and other assemblies. We support custom manufacturing according to customer drawings or samples, and can adjust material, size, hole position, surface color, and machining tolerance to meet your specific installation requirements.
