Basic Terms of Pressure-Locked Gratings<\/strong><\/h2><\/div>\n\n\n\n

Floor gratings<\/strong> are load-bearing, plate-like structural elements whose flat sides contain numerous through-openings arranged in a regular pattern, so that the free cross-section usually accounts for more than 70% of the total area. Floor gratings consist of vertically positioned load-bearing bars arranged parallel to each other and intersected at regular intervals by cross bars (transverse bars) that ensure their mutual positioning. Gratings are used as easily installable prefabricated load-bearing elements, especially for floor surfaces, platforms, walkways, stairs, etc. The main advantages of floor gratings are their good light and air permeability, high load capacity combined with low weight, easy installation and removal, and the fact that dirt cannot accumulate on their surface.<\/p>\n<\/div><\/div>\n\n\n\n

\"\"<\/div>

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

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

\"\"<\/div>

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

Transverse bars to the load-bearing bars, welded or pressed into them at the intersection points.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

FRAME<\/h3><\/div>

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

\"\"<\/div>

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

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

\"\"<\/div>

MESH SPACING<\/h3><\/div>

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

\"\"<\/div>

LOAD-BEARING LENGTH<\/h3><\/div>

External dimension of the grating in the direction of the load-bearing bars. This dimension is referred to as the length even if it is smaller than the width.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

NON-LOAD-BEARING WIDTH<\/h3><\/div>

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

\"\"<\/div>

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

Distance from the center (axis) of one support to the center (axis) of another support. The clear support spacing is the clear distance between supports.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

CUT-OUTS<\/h3><\/div>

Shape modifications \u2013 cuts or openings in the grating.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

MAL\u00c9 CUT-OUTS<\/h3><\/div>

\"\"<\/div>

KICK PLATE<\/h3><\/div>

An edge projecting above the top surface of the grating (at least 100 mm). It reinforces the grating edge and prevents objects from falling.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

P\u0158E\u010cN\u00cdVAJ\u00cdC\u00cd FRAME \/ VYBR\u00c1N\u00cd<\/h3><\/div>

Used when it is necessary to keep the top edge of the grating at the same level as the surrounding structure.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

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

\"\"<\/div>

BEARING SEAT<\/h3><\/div>

The width of the grating bearing on the supporting structure. It usually equals the grating height, but is at least 30 mm.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

A flat perforated piece welded to the stair tread, allowing it to be bolted to the stringer.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

A 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 GRATING TYPE P<\/h3><\/div>

Gratings where a special formed modification is made on the top edge of the cross bars and\/or load-bearing bars to increase the anti-slip properties of the surface covered by the gratings.<\/p><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
