6. Roof: The roof will be constructed by several die-stamp corrugated steel sheets with a certain upwards camber at the center of each trough and corrugation, these sheets are butt jointed together to form one panel by automatic welding.

6.1. Roof Panel:

6.2. Roof reinforcement plate: Four 3.0mm thickness, reinforcement plates are mounted around the four corner fittings.

7. Other:

7.1. Lashing Rings: Lashing rings are welded to each bottom and top side rail at corresponding recessed area of side wall.
