Figure 3 shows a carport sector viewed from below.
![Steel roof structure of a free standing carport](parking-lot-structures/structure-4/3-carport.jpg)
The two I-beams are carrying beam B and connected to beam A and C. Figure 4 shows the I-beams to beam A connections.

The I-beams upper flanges are connected to the bottom side of beam A by welding. Beam A consists of two side-by-side placed rectangular hallow profiles.
