Steel / Metal Building Features

Base Conditions

Many steel / metal building suppliers will not offer details of base conditions and applications for different uses. They also do not show which application is on the metal building quotes.

All Austin Building Systems, Inc. commercial steel / metal building quotes clearly state the type of base condition. This eliminates confusion upon pricing and ordering. Below are the all types of base conditions that are available for standard 26 gauge fully sheeted commercial metal buildings.

Standard Base Angle: Standard base angle options require a 1 1/2" x 1 1/2" notch outside the building dimensions in the concrete slab. For example, with a 50' x 100' commercial steel building, the overall slab would be 50'3" x 100'3". This is standard on all steel buildings, and the most cost efficient on building materials. The disadvantage of the notch is that the concrete contractor will have more time and materials in building the notched slab.

Base Trim Option: The base trim option does not require the 1 1/2" x 1 1/2" notch in the concrete, and the trim itself will match the wall color. The advantage of this option is that the concrete supplier does not have to notch the slab, and the slab is the same size as the building. For example, a 50' x 100' steel building will have a slab measuring 50' x 100'.

Deluxe Base Trim: Deluxe base trim is a one-piece trim, easier to install than standard base trim, and does not require a notch in the concrete slab. The advantage of the deluxe base trim is that the concrete slab does not have to be notched. The concrete slab is the same size as the building. The disadvantage of the deluxe base trim is that the trim only comes in a burnished slate finish. (refer to color guide)

Base Channel Option: The base channel option is used to support interior liner panel options. The base channel does require the 1 1/2" x 1 1/2" notch in the concrete slab, extended beyond the dimensions of the steel building. For example a 50' x 100' steel building with the base channel option would require a concrete slab with dimensions of 50'3" x 100'3".

Base Channel with Base Trim: The base channel with base trim option supports interior liner panels, and improves the overall aesthetics of the building. It does not need a notch in the concrete slab. The disadvantage is that the building materials cost would be more.

Base Girt Option: The base girt option is primarily used for buildings that will have gravel or dirt floors, typically in agricultural, farming, riding arenas, or basic storage buildings. The base girt option does require a 1 1/2" x 1 1/2" notched concrete slab, notched pier frame support at the frame lines or perimeter footer.
