Pressed Grating Stair Treads P<\/strong><\/h2><\/div>\n\n\n\n

Stair treads P<\/strong> are manufactured in accordance with DIN 24531-1<\/strong>. For standard stair treads, bearing bars with dimensions 30 x 2 mm, 30 x 3 mm and 40 x 3 mm<\/strong> are used. A perforated anti-slip nosing is welded to the front edge of the treads, which not only reduces the risk of slipping, but also increases the structural load capacity of the tread and visually highlights its leading edge. The treads are equipped with 3 mm thick side plates with bolt holes. Standard tread dimensions are also available with an alternative side plate design \u2013 see image (more information in the attachment below). Tread dimensions and hole spacing in the side plate are listed in the following table.<\/p>\n\n\n\n

Installation of stair treads<\/h2><\/div>\n\n\n\n

During installation, it is necessary to check whether there is excessive clearance between the stair tread side plate and the stringer due to tolerances of these structures. If so, this clearance must be compensated with spacer washers before bolting the stair treads to the stringers. This prevents damage to the welds of the stair treads.<\/p>\n\n\n\n
