I've constructed a 26x18 panel using 3–4" wide Maple strips, and I'm concerned about it warping over time. I've read that steel battens can get bent due to warp strength, but I feel like using a 1/2" thick breadboard end might not be effective. What are the best methods to keep my beautiful new panel flat?

Make sure to finish both sides and all the edges uniformly at the same time, applying at least six coats. Maple isn’t the worst when it comes to warping, so fingers crossed! I’ve got a 30-year-old maple dining table with a 3/4" thick top that has survived moving all over and hasn’t warped at all.
To really tackle warping, you should ideally start with quartersawn wood for your strips. This means the end grain should be as perpendicular to the surface as possible, which helps prevent twisting or cupping. Selecting the right pieces from the start is key. However, since it's too late for that, what’s the next best thing to ensure stability?
Are you sure you need to stress over this? If it warps just a bit, it might not be a huge deal. For example, if you're hanging it, one corner might just lift off the wall a bit. But if you’re integrating it into a wood structure, consider using figure 8 fasteners to allow for wood movement.
