During our B.I.S.C Frame Load Test #1, 500 lbs. of concrete is placed on our standard frame configuration on the front of the church chair legs without any frame fatigue. During the B.I.S.C. Frame Load Test #2, 1000 lbs. of concrete is placed on our standard church chair frame configuration without any frame fatigue.
We further reinforce our extremely durable 1010, 16-gauge frames with an innovative torsion bar design that supports the leg structure while absorbing and dispersing shock away from the weld joints during stacking and unstacking. 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 [...]
We begin our process by purchasing precision welded, high-quality 1010 cold rolled steel tubing manufactured in the USA exclusively to Bertolini’s radius specification. 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 [...]
Durability is a key factor in the manufacturing of Bertolini church chairs. Bertolini chairs are designed to withstand any wear and tear that can arise through years of use. Bertolini chairs are designed to be fully functional for years to come without any maintenance at all. The chair will remain durable far beyond the lifetime [...]
