Angles, shapes and sections

73.01 Sheet iling of iron or steel, whether or not drilled, punched or made from assemb ed elements; welded angles, shapes and sections, of won or steel. 7301.10 - Sheet piling 7301.20 - Angles, shapes and sections Sheet iling consists of sections obtained by rolling, drawing, pressing, press-folding or forming on rol er machmes, or by assembling rolled parts (e.g. by riveting, welding, crim in@. These sections can be fitted to each other by belng simply interlocked or even by avlng their es have, on the longitudinal sides at longitudinal sides juxtaposed. For this urpose, both least, connecting devices (e.g. grooves, fanges, interloc s . I' PI g This heading includes : (1) Sheet pilin an le or comer pieces, which are sections intended to form corners; for this purpose eit er olded sections or sections which are cut along their length are used, the parts so obtained being then welded or riveted to form an angle. % f (2) Joining sheet piling sections with three or four arms for making partition walls. (3) Connecting sheet iling sections whose shape enables them to be used for connecting different types of s eet piling. R (4) Sheet piling conduits and columns which are driven into the ground in such a manner that they join together without being forcibly interlocked. The sheet piling conduits are corrugated in shape. Sheet piling columns are made up of two sections welded together. Sheet piling is generally used for makin walls in sandy, waterlogged or submerged ground for civil engineering works such as dams, dy es or trenches. \ The headin also includes welded angles, shapes and sections. The Explanatory Note to heading 72. 6 applies, mutatis mutandis, to profiles obtained by welding. f The heading does not cover (a) Welded hollow profiles (heading 73.06). @) Sheet piling assembled into piles which have no " interlocks " available for external connection (heading 73.08).
