This technology combined with superior welding makes for a very durable church chair. To learn more go to church chairs by [...]
The steel used to manufacture Bertolini’s church chairs is mandrel-bent resulting in a more attractive, secure, and stronger bend. Many church chair makers form their frames using crush bending, a technique that weakens the frame and leaves an unattractive indentation. In contrast mandrel bending places an insert (a mandrel) into the tube when the bend [...]

Cold rolled steel provides the optimum surface for powder coat adhesion. While other stackable seating manufacturers use weaker 18-gauge tubing merely to cut costs, Bertolini uses 16-gauge tubing on all their church [...]
