Wall
Base Conditions |
|
| Ceco’s
standard base condition is to use this member without a panel
notch in the concrete foundation since the Base Angle/Trim
provides support for wall panels and closes off the open ribs
at their base. However, dimensions of member are such that
it can be used in conjunction with a panel notch, if so desired
by the customer. |

| Girts
are either roll formed “Z” sections, 8 ½” or
10” deep, or roll formed “C” sections, 8 ½” deep.
Each flange of these members has a stiffening lip formed at
50° to the flange on “Z”s and at 90° on “C”s. |
