Outside corner trim on a metal outbuilding is used to both keep the elements from entering your structure, and protect people from cuts. Installing outside corner trim is a straightforward process. The metal is sharp, but careful handling and the use of work gloves will reduce the danger of lacerations.
Metal buildings do not have a specification for sealing the outside metal corner during installation. Sealing the corners will depend on the use of the finished building.
Step1
Measure the length of the outside corner trim. The total length of the metal corner will be equal to the length of the wall panels on the building. Use a ladder to ensure that you get the accurate length for the metal corner trim.
Step2
Mark the total length you measured from the side of the building on the outside corner trim. Cut the trim at the mark with the aviation snips. On the mounting flange of the metal trim, place a mark one inch in from each end. Measure between the marks and divide by 12, the recommended distance between hole centers. This will give you the amount of screws needed for each side of the outside metal trim. If you get a decimal number, round to the nearest whole number.
Divide your total length by the number of screws per side to get the exact distance between screw centers.
Example: The distance between 1 inch marks equals 88 inches. Divide 88 inches by 12 inches, which is equal to 7.33. Therefore each mounting flange will have 7 screws in between the screws located 1 inch in from each end. The total length of 88 inches divided by 7 equals 12.57. Multiply the .57 by 16 to convert the decimal to a fraction. .57 times 16 equals 9.12 or 9/16th of an inch.
Step3
Install the outside metal corner trim to the metal building by screwing a #14 by 1 inch self-tapping screw through the corner trim’s mounting flange, into the wall panel. Plumb the trim and finish screwing the outside corner trim to the wall.
