Frequently Asked Questions
When would a roof edge need a 3-Way Edging?
3-way edgings protect roof elements, by going around the edge due to return of the third leg, for example for fascia boards.
What metals can I get 3-Way Edgings in?
3-Way Edgings are commonly made from prepainted steel and Zincalume.
What gauge are 3-Way Edgings?
3-Way Edgings are most commonly available in 28-gauge and 26-gauge thicknesses.
Which ASTM standard applies to 3-Way Edgings?
The applicable standards are ASTM A653 for galvanized steel, and ASTM A792 for Zincalume.
What is the difference between 3-Way Edgings and 2-Way Edgings?
A 2-Way Edging is a two-leg (horizontal and vertical) L- shape metal edge. A 3-Way Edging adds a third leg (return), so it is used where the edge detail needs an extra return, most commonly to go around the edge of fascia board.
Should I use galvanized or Zincalume for 3-Way Edgings?
Prepainted steel (available colors include brown, charcoal, gray, and white) is the general-purpose choice for 3-Way Edgings. Zincalume holds up well where salt air or constant damp is a factor due to the additional layer of organic coating. Bonderized steel can be soldered to create watertight corner connections and is the best option when the material needs to be painted on site. Copper is recommended for coastal areas.
