A header is an important structural beam that goes above windows and doors in buildings. It supports the weight of the wall and roof above these openings, preventing sagging or collapse. Think of it like a bridge that carries weight across a gap. In construction job descriptions, you might see it called a 'door header,' 'window header,' or 'structural header.' It's a crucial part of framing work that requires proper sizing and installation to meet building codes and ensure safety.
