Door construction and method |
摘要 |
A door construction includes first and second door blanks each defining an L-shaped profile including: (i) a back member; (ii) a base member. The blanks are secured in opposed nesting relation to define first and second seams. The first and second seams. The first and second base members define edges of the door. The base member of the first blank defines a foot including a first contact surface and the back member of the first blank is folded upon itself to define a second contact surface. The base of the second blank defines a foot including a third contact surface and the back member of the second blank is folded upon itself to define a fourth contact surface. The first seam is defined at the abutment of the first and fourth contact surfaces, and the second seam is defined at the abutment of the second and third contact surfaces.
