When I replaced my front door two years ago, I had the exact same confusion. Steel looked solid and secure, but every installer kept warning me that it can dent easily if the area gets a lot of traffic or if you move furniture around often. Fiberglass, on the other hand, surprised me with how well it holds up against scratches and temperature changes. The insulation was noticeably better too, especially during winter. I also liked that it comes in more textures, so you can match it to different exterior designs without repainting all the time. Before choosing, I compared detailed specs — Highly recommend visit official site for detailed product specs. It helped me see the weight, insulation values, and durability differences clearly. Based on that, fiberglass felt like the safer choice for daily use.
