Wyatt -- if it still cracks heat it to 600ºF for ten minutes to anneal it. If it's softer it'll flex easier and shouldn't break. Since 600ºF will be hard to achieve for most people 500º in the oven will be close 'nuff.
That's what I can't figure about these people that buy trailers with expanded metal floors ... they crack around the welds! Expanded metal or tempered screens can't flex if they are mounted solid.
