Steel Stud Drywall Partition Screw Spacing and Location

It should be noted that Underwriters Laboratories provides technical assistance in the interpretation of conditions that are not specifically tested. This assistance is based on the enormous amount of data available to UL on a variety of materials and systems. Many of these situations may have already been reviewed by UL or may have been tested by UL under the so-called "Special Services Investigations."

Examples of these would be the evaluation of corner details that do not specifically fall under the scope of ASTM Standard E119 or the installation of recessed electrical panels in fire-rated walls. Architects and contractors should consult with the manufacturer of the gypsum panels being used in the specific project for assistance regarding special situations.
