Anti-slip gratings

Usage of anti-slip gratings :
The anti-slip gratings design is used in places with demanding operating conditions caused by oil, grease, moisture, ice die to the increased risk of slipping and injuries.
Anti slip gratings are prescribed mainly for ramps – leaning platforms with a slope from 6° to 10°C.
They have got ribbed anti-slip correction on bearing bars.
Construction, mesh size, type bearing bar and parameters of XSP gratings are same as forge-welded SP gratings.
Anti-slip gratings we marks by the letter X before the designation of individual types of gratings.

According to the anti-slip class and regulation BGR 181, we devide the gratings into several anti-slip classes R10 to R13.
Standard gratings type SP and P we classify as R10.
Anti-slip gratings type XSP we classify as R11,
Anti-slip gratings XP Type 2 we classify as R11,
Anti-slip gratings XP Type 3 we classify as R12,
Anti-slip gratings XP Type 4 we classify as R11.

Anti-slip forge-welded gratings type XSP
Gratings has ribbed anti-slip correction on bearing bars.
Construction, mesh size, type bearing bar and parameters of XSP gratings are same as forge-welded SP gratings.

By request we are able to produce sharp ribbing

They are produced in many variations.
Type 2 gratings has standard anti-slip correction on bearing bar.
Type 3 gratings has standard anti-slip correction on bearing bar also on non-bearing bar.
Type 4 gratings has standard anti-slip correction on non-bearing bar 
Construction, mesh size, type bearing bar and parameters of XP gratings are same as pressed P gratings.

Anti-slip full gratings can have anti-slip correction only on single bar.

Table of load for anti-slip gratings XSP and XP
Due of weaker cross section on bearing bars material of gratings is necessary to reduce modelary values of loadings, which are defined in tables of loadings for no-ribbed (smooth) SP also P gratings.
The load of anti-slip gratins Type 1, Type 2, Type 3 and Type 4 are decreased values apx. 20% for gratings with bearing bar of height 25 – 40mm and about apx. 10% for gratings with bearing bar of height 50 – 80mm.
Deflection of anti-slip gratings is decreased  15% for gratings with bearing bar of height 25 – 40mm and around 5% increased for gratings with bearing bar of height 50 – 80mm.

For inclined platform and on a pedestrian bridge with a gradient from 10º to 24º has to be used anti-slip gratings with anti-slip rails, which are welded to the gratings one behind the other at a recommended distance of approximetely one step.

T – distances between anti-slip rails, approx. 500 mm
b – rails width 10-30 mm
h –  rails height5-20 mm
α – platform leaning angle from 10º to 24º
