Trim Options for Base Conditions




A formed base trim is a type of base framing that utilizes a formed shape and detents. It creates a pocket for fastener clearance and acts as base trim to support the base of the wall panel, depending on the wall panel type and base condition.

The standard base attachment is formed base trim.


This diagram shows various base conditions for steel buildings. Your building specifications and end-use will determine which base condition is appropriate for the project.

Each base condition has the option to add base trim. As the diagram indicates, when base trim is added to the base condition, it relocates the panel flush with the concrete and places an additional piece of steel between the wall panel and foundation.

The advantages of opting for base trim are numerous:

  • Eliminates the need for a panel notch on your building slab saving you labor and money
  • Covers the pointed-end of screws at the bottom of walls inside of the building
  • Prevents the cut edge of the wall panels from coming into contact with concrete (which can void any coil coaters warranty on painted sheeting)
  • Covers any irregularities on the edge of your slab to provide a neater, more attractive finished look

If you do not opt for base trim, it is recommended that the concrete foundation is notched to allow for recessed sheeting. Non-recessed sheeting exposes the ribbing at the base of the wall panels around the perimeter of the steel building.

Note: If liner panel is chosen as an accessory, the base condition at lined walls will automatically be added.
