Weather can be a big factor. We had a metal patio at our previous house, and after years of freezing winters and hot summers, a couple of joints started showing small cracks. At first we thought it happened overnight, but looking back, there had been tiny signs for months that we ignored. A local welder repaired the damaged area and suggested checking the structure every year for loose welds, rust, or water collecting in certain spots. Since then, I’ve realized that regular maintenance makes a huge difference. Even simple things like cleaning away dirt and touching up chipped paint can help slow down wear and keep the metal in much better condition.
