All metal buildings have some type of base connection along the building perimeter to enable the connection of sheeting. The base condition determines how the panels connect to the foundation. To prevent water and pests from entering the building at the base, panels extend below the finished floor of the steel building. Base condition options include, standard base angle, deluxe base trim, base girt, and base channel.

The base angle is the standard base design in the industry. Standard base angle condition consists of a single angle member, attached to both the wall sheets and the slab. It is a continuous angle secured to foundation to support wall panels.

Deluxe base trim is another option for buildings with concrete slab foundations. Deluxe base trim combines base angle and trim into one piece, providing all the benefits of base trim and base angle. Together with the base angle forms a tight seal keeping out water, dirt and critters. Also make erection easier, faster and makes the metal building more attractive.

The base girt option is designed for steel buildings that sit on piers rather than a full slab. A base girt system does not rest on or attach to the foundation.

Base channel is a CEE shaped section that runs the perimeter of the steel building connected to the floor. It is most commonly used when a liner panel, or interior wall, is going to be installed. The CEE section provides a pre-positioned connection point for inside panels. This approach requires a sheet notch in the slab.
