Mustang Sign Assembly
Because Plaskolite MUSTANG sheet is specifically engineered as a best-in-class sign material, it’s also designed to allow for easy sign assembly. The Plaskolite MUSTANG fabrication guide details how standard sign-assembly methods may be applied.
Assembly
Typical sign cabinets use aluminum extrusions to engage the edges or flanges of the MUSTANG sign face. A hanger bar (hanging strip, hanging lug, etc.) is used along the top of the MUSTANG sign to correct any sagging or bowing of the sign face. This technique is commonly used in warmer climates and with large signs to prevent the weight of the sign from resting on the lower portion of the sign can or frame. This reduces the possibility of sign deformation due to high temperatures.
If mechanical fasteners must be used, allow room for expansion and contraction. A method of attachment to prevent the MUSTANG sign face from binding on the sign cabinet includes a spacer that is slightly taller than the thickness of the sheet and the sign cabinet combined, inserted through the oversized hole and slot (also called a bushing).
Internal tie bars and soft bumpers are sometimes used to attach a large sign face to the sign cabinet. This will aid in preventing the sign face from blowing in, out, or dislodging during extreme weather conditions.
Ventilation
To help prevent sign face distortion caused by excessive heat buildup, cabinet ventilation should be provided. Consider additional venting when the sign face is decorated with dark paints or dark vinyl.
Attachment Of Trim Cap
An adhesive must be used to bond MUSTANG to the cellulosic trim cap material used in the production of channel letters. Weld-On #55, Weld-On #58, and Lord Adhesives #406/17 have been found to work well with bonding MUSTANG to the trim cap material.
