Abstract

A drywall trim for protecting drywall can include a metal body having a seam with a longitudinal axis. The metal body can include wings or planar portions that extend from the seam in transverse directions relative to the longitudinal axis. The planar portions can be formed at an angle relative to each other. At least one of the planar portions can have an outer edge that is not parallel to the seam. Paper can be bonded to the metal body.

Claims (29)

1 . A drywall trim for protecting drywall, the drywall trim comprising:

a metal body comprising a seam having a longitudinal axis and planar portions extending from the seam in transverse directions relative to the longitudinal axis, the planar portions being formed at an angle relative to each other, and at least one of the planar portions comprises a continuous outer edge that is sinusoidal having symmetrical peaks and valleys; and

paper bonded to the metal body, wherein the paper comprises:

a first layer on a first side of the metal body, the first layer comprising a greater transverse width than the metal body and an outer edge that is complementary in shape to the outer edge of the metal body; and

a second layer on a second side of the metal body opposite the first side.

2 . The drywall trim of claim 1 , wherein both of the planar portions comprise outer edges that are not parallel to the seam.

3 . The drywall trim of claim 1 , wherein the outer edge comprises waves.

4 . The drywall trim of claim 1 , wherein the outer edge comprises oscillations.

5 . The drywall trim of claim 4 , wherein the oscillations repeat in pattern having a range of about 6 inches to about 12 inches.

6 . The drywall trim of claim 1 , wherein the outer edge is serrated.

7 . The drywall trim of claim 6 , wherein the serrations comprises the peaks and the valleys that are radiused.

8 . The drywall trim of claim 7 , wherein the radii are in a range of about 0.1 inches to about 0.5 inches.

9 . The drywall trim of claim 6 , wherein the serrations repeat in pattern having a range of about 1 inch to about 2 inches.

10 . The drywall trim of claim 1 , wherein the metal body comprises steel.

11 . The drywall trim of claim 1 , wherein the planar portions are orthogonal relative to each other.

12 . The drywall trim of claim 1 , wherein the planar portions are non-orthogonal relative to each other.

13 . The drywall trim of claim 1 , wherein the planar portions are at an acute angle relative to each other.

14 . The drywall trim of claim 1 , wherein the planar portions are at an obtuse angle relative to each other.

15 . The drywall trim of claim 1 , wherein the paper comprises paper outer edges that are not parallel to the seam.

16 . The drywall trim of claim 1 , wherein the first side is a convex side of the metal body.

17 . The drywall trim of claim 16 , wherein the second side is a concave side of the metal body.

18 . The drywall trim of claim 17 , wherein the second layer has a transverse width that is substantially equal to that of the metal body.

19 . The drywall trim of claim 1 , wherein the first side is a concave side of the metal body.

20 . The drywall trim of claim 19 , wherein the second side is a convex side of the metal body.

21 . The drywall trim of claim 20 , wherein the second layer has a transverse width that is substantially equal to that of the metal body.

22 . The drywall trim of claim 1 , wherein the first and second layers of paper comprise a same transverse width.

23 . The drywall trim of claim 1 , wherein the first and second layers of paper comprise a different transverse width.

24 . The drywall trim of claim 1 , wherein the second layer has a transverse width that is substantially equal to that of the metal body.

25 . The drywall trim of claim 1 , wherein the drywall trim comprises a cornerbead or paperbead.
