Basic terms of forge-welded gratings<\/strong><\/h2><\/div>\n\n\n\n

Floor gratings<\/strong> are load-bearing, plate-like construction elements whose flat sides have many through openings in a regular arrangement, so the open area typically accounts for more than 70% of the surface. Floor gratings consist of vertically positioned load-bearing bars, arranged parallel to each other and crossed at regular intervals by spacer (cross) bars ensuring their mutual position. Gratings are used as easily installable prefabricated load-bearing elements, especially for floor areas, platforms, walkways, staircases, etc. The main advantages of floor gratings are their good permeability to light and air, their high load capacity with low self-weight, easy installation and dismantling, and also the fact that dirt cannot settle on their surface.<\/p>\n<\/div><\/div>\n\n\n\n

\n
\"\"<\/div>

BEARING BARS<\/h3><\/div>

Flat bars between two supports of the grating. They carry the load and are arranged parallel to each other.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

CROSS BARS \/ SPACER BARS<\/h3><\/div>

Cross bars to the bearing bars, welded at the intersections with these bars or pressed into them; bars to the bearing bars, welded at the intersections with these bars or pressed into them<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

EDGING<\/h3><\/div>

Perimeter edging of the grating, usually with a height identical to the height of the grating.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

MESH SIZE<\/h3><\/div>

Clear distance between bearing bars and between cross bars.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

MESH PITCH<\/h3><\/div>

Center-to-center distance between bearing bars and between cross bars.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

BEARING LENGTH OF THE GRATING<\/h3><\/div>

Outer dimension of the grating in the direction of the bearing bars. This dimension is called the length even if it is smaller than the width.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

NON-BEARING WIDTH OF THE GRATING<\/h3><\/div>

Outer dimension of the grating in the direction of the cross bars. This dimension is called the width even if it is greater than the length<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

SUPPORT SPACING<\/h3><\/div>

Dimension from the center (axis) of the support to the center (axis) of the support. The clear span between supports is the clear distance between the supports.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

CUTS<\/h3><\/div>

Shape modifications \u2013 cuts or cut-outs in the grating<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

SMALL CUTS<\/h3><\/div>

Shape modifications \u2013 cuts or cut-outs in the grating, the length of which does not exceed 0.5 linear meter.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

TOE BOARD<\/h3><\/div>

Edging protruding above the top edge of the grating (minimum 100 mm). It reinforces the grating edge and prevents objects from falling.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

PROTRUDING EDGE \/ REBATE<\/h3><\/div>

Used in cases where it is necessary to maintain the same level of the top edge of the grating and the surrounding structure.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

SUPPORTING STRUCTURE<\/h3><\/div>

Structure on which the gratings are placed.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

GRATING BEARING<\/h3><\/div>

Bearing width of the grating on the supporting structure. Usually equal to the height of the grating, but at least 30 mm.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

STAIR TREAD SIDE PLATE<\/h3><\/div>

Flat material with holes, welded to a stair tread, allowing bolting to the stringer.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

SAFETY NOSING<\/h3><\/div>

Profile welded to stair treads and landings to prevent slipping, increase load capacity, and visually highlight the leading edge of the stair tread.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

ANTI-SLIP SP GRATING<\/h3><\/div>

Gratings where a special shaped finish is made on the top edge of the bearing bars to increase the anti-slip properties of the area covered by the gratings.<\/p><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
