Abstract
An elongate profile (1) having a first portion (2) and a second portion (3), the first and second portions (2, 3) being joined together at a first joining portion (JP1), the first and second portions (2, 3) being non collinear, the joining portion (JP1) comprising an array of raised or rebated formations (10a), each formation extending across the joining portion (JP1) in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array (10A) and the pitch (P) between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness (G) of the flatlands.
Claims12
An elongate profile having a first portion and a second portion, the first and second portions being joined together at a first joining portion, the first and second portions being non collinear or non coplanar, the joining portion comprising an array of raised or rebated elongate formations, each raised or rebated elongate formation extending across the joining portion in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive raised or rebated elongate formations in said array, where the flat lands are free of formations, and the pitch P between successive raised or rebated elongate formations in said array being from 2 to 20 times the thickness G of the flat land, and
- wherein in a direction along the array from 30-70% of the distance is taken up by the width W of the raised or rebated elongate formations.
