These are much too big for chiles, but I have giant tomato cages from 6" reinforcing steel, the kind that might be in a concrete driveway. It's 5 feet wide and comes in 50' rolls. Cut into 7 pieces about 7' long (2 will be 6" longer) and form into circles a bit more than 2' in diameter, bending the wire ends to lock them together. They're very strong and the 6" gaps are big enough to pick tomatoes, weed, cultivate, etc. For peppers, I use smaller tomato cages, about 3' and let the plants grow up through them. Jim
