Abstract

The metal ladder is formed of aluminium, having two profiled uprights to which the rungs are fitted or welded. In cross-section, each upright is formed by two chambers (4,5) joined together by a central web (6). The external sides (7,8) of the chambers extend obliquely from the centre, and are attached to the web. The internal sides (9-12) can be bent at right angles, forming a radiused or chamfered ridge (13, 14).
