Heavy duty version of our pivot bar

Question

We live in a loft in a hundred year old textile mill that was renovated a decade ago. Attached is a photo of one of the four large windows in our unit. In the fall and spring, we like to open the bottom windows for fresh air circulation. All other sections are stationary. The windows are double pane and the raiseable sections measure 34" H x 49"W. We've had ongoing issues with the pivot bars bending from the weight of the window. Last year we purchased eight (8) replacement die-cast pivot bars from your company. All worked well for a bit, but slowly each bent and now only one of our windows easily raises and stays in place.

Is there a more heavy duty version of the die-cast pivot bars we purchased that will resist bending?

Thank you in advance for your speedy response.

I see you ordered our 26-403. Now, we have a straight steel pivot bar that may work. See our 26-063. It doesn't have the offset like your 26-403, but that might not be critical. It should hold up better, seeing as how it's steel. You would just have to remove the screw that comes with it and discard it. The back hole will line up for you to use the bottom sash screw.
