Structural member

A structural assembly (10) comprising:

• a first structural member (100),
• a second structural member (200), and
• a lock plate (300);
• each of the first structural member (100) and the second structural member (200) extending along a longitudinal direction and having:
• a first portion (102, 202) which extends along the longitudinal direction in a first plane;
• a second portion (103, 203) which extends away from the first portion (102, 202) and which extends along the longitudinal direction in a second plane at an angle to the first plane;
• the first portion (102, 202) of the first structural member (100) and second structural member (200) being provided with:
• an engagement feature (102, 204) configured to interlock with a compatible engagement feature (304) provided on the lock plate (300) of the structural assembly,
• wherein the engagement feature (104, 204) of each structural member (100, 200) is provided as a tooth member (150, 250) which extends from a longitudinal edge of the first portion (102, 202), the tooth members (150, 250) and each structural member (100, 200) being integrally formed out of a respective single piece of material;
• and
• the second portion (103, 203) of the first structural member (100) and second structural member (200) being provided on a longitudinal end face with:
• compatible seating features (106, 206) configured to seat one of the structural members (200, 100) on the other structural member (100, 200) such that the longitudinal directions of the structural members (100, 200) are aligned.
