<p>The non-slip grating elements are produced by folding and punching steel plate and this permits a reduction in wt. of the elements. Support legs are formed by folding the plate and the elements are joined together by clamping, which allows rapid assembly. The elements have a max. length of 6m. and the nonslip surface is produced by slots punched at right angles to each other. The elements can be used in all places where non-slip grating is necessary, including metal staircases and they could also be used as storage shelves.</p> |
