PLATFORM GRATES WORLD
THE BEST PLATFORM GRATES WHICH COMESTO THE MIND ARE MANUFACTURED BYPOLIMEX-MOSTOSTAL SIEDLCE S.A.
Man needs safe and solid ground to stand on,a complete safety feeling,stability ,security and reliability.It's enough-the nex one is coming up
It is the coming up,
Which comply with;THE HIGHEST QUALITY STANDARDSAs the results ofTHE ADVANCED TECHNOLOGY ANDTHE ANTICORROSION PROTECTION
WHAT THE MAN WALKS OVER ?
BY THE WAY,WE ARE THE BIGGESTPLATFORM GRATESPRODUCER IN POLAND,TRY OUR CAPASITY AND EXPERIENCE

2Let's have a lookWe produce theaccording to the DIN 24537 norm andanticorrosion protection by the hot-dipzinc galvanized processaccording to the EN ISO 1461 (DIN 50976).You can adapt our products in manydifferent ways.
...We walk over the grates which are thefactory platforms,and the overheadtraveling crane platforms,and the cranetrack platforms.We walk over the platformgrates of the pipeline and the tankcommunication runs are constructed,and also the walkways onthe pedestrian gangways and the bridges.The platform grates which cover themanholes and the sewers serveas a protection against accident.
...We walk over the grates up and down,when they form different industrialstaircases-straight and curved,high and low.
...The platform grates can also be applied asdecorative or stage elements for the culturalevents(outdoor and indoor) for exampleas stages,foot paths,runs,building sidingsand so on
is offering ifferent sizes and shapes of gratesaccording to ours customers needs.With regard to production technology andto manufacturing we present the platformgrates in two kinds:
With both kinds we will present thei.e.special type
of anti-slip grates,and also
We will also present the WINDING STAIRSwhich are manufactured on the same basis,as well.

THE WELDED PLATFORM GRATES
These grates are manufactured of thesupporing flats of different dimensionsand of the specially made(transverse) rods.The transverse rods are welded to the supportingflats with the resistance welding method.
Welded grates mesh standard pitchas in the DIN 24537 norm

Typical width of the platform grates at the flat of carrying bar 25.5 and 34.3 mmconstant pitch
The typical width grid example
In this range the maximum deflection at the500 daN/m continuous load is 1/200 of thesupport spacing.

The range recommended by the manufacturer.In this range the elastic deflection is no more than1/200 of the support spacing and is less than 4 mmat the 150 daN single moving load at the 200 x 200 mmpressure area at any grates point.
In this range the grates can accommodatethe 150 daN moving load at any point whilethe maximum deflection is 1/200 of the supportspacing.
In this range the maximum deflectionat the 500 daN/m continuous loadis 4 mm

SERRATEDWELDED GRATES
The serrated grates are describedby the enlarged friction coefficient.The supporting flats are cut withtooth in order to enlarge the anti-slipprotection.
These grates are applied to coverthe platforms where the safety is endangeredbecause of snow ,ice,greaseand humidity.
The technical specifications(load,weights,
mesh size and supporting flat dimensions)
are the same as for the standard grates.
The Serrated Grates are machined
to different shapes and dimensions
in accordance with the customer wish.

PRESSEDPLATFORM GRATES
Standard largness of the meshfor pressed platform grates
We manufacture these grates by the speciallycut (the tapering cut-outs) of the supporting flatjoined with the transverse flats.The joining process is conducted at the advancedtechnology line.It relies on the pressing of oneflat into the another flat under the heavy thrustpressure(up to 1650 kN per single flat)
-
In this range the maximum deflection at the500 daN/m continuous load is 1/200 of thesupport spacing.
2
In this range the maximum deflectionat the 500 daN/m continuous loadis 4 mm
2
In this range the grates can accommodatethe 150 daN moving load at any point whilethe maximum deflection is 1/200 of the supportspacing.
The range recommended by the manufacturer.In this range the elastic deflection is no more than1/200 of the support spacing and is less than 4 mmat the 150 daN single moving load at the 200 x 200 mmpressure area at any grates point.

Pressed grates loadingcalculation table
The Fv loading table for the pressed grateswas prepared for the supporting flat module equalto 33,33 mm.To calculate loading for the pressed grates withthe other supporting flat module use the above table.
Example of the loading calculationfor the Grates with the pitches differentthan 33,33 mm
The continuous load value is:Fv = 2430 daN/m for the KP(33x33/30x3)grates,L = 800 B = 1000 To calculate Fv*the continuousload value for the grates with the supportingflat module equal to 11,11 mm forthe KP(11x33/30x3) grates,L = 800,B = 1000
2
To calculate the continuous load value for thegrates with supporting flat module equal to 66,66 mmfor the KP(66x22/30x3)grates,L = 800,B = 1000
Fv*= Fr x w = 2440 x 0.52 = 1270 daN/m2
SERRATEDPRESSED GRATES
The serrated pressed gratescan be produced in three kinds:Type 1 - the cut - outs made only in thesupporting flats.Type 2 - the cut - outs made only in thejoining flatsType 3 - the cut - outs made only in thesupporting and in the joining flats.
Similarly as the Welded Grates
the Serrated Pressed Grates are applied
to cover the platforms
where the safety is endangered because
of snow, ice, grease, and humidity.
The technical specifications (load,weight,
mesh size and supporting flat dimensions )
are the same as for standard grates.
The Serrated Pressed Grates
are machined to different shapes
and dimensions in accordance with
the customer wish.
