A new product from Mostostal Siedlce Sp. z o.o.!

Platform gratings with a tear plate cover — the so-called GRATE-CHECK

Grate-Check gratings are a combination of a platform grating and a tear plate. They are used in facilities where leakproof and light weight floor is needed. Both welded and pressed gratings can be used for this type of product. Merging grating and a tear plate is carried out by welding.

Grate-check characteristics: Increased load-bearing capacity by 65% compared to the grating itself Possibility to use fewer supports Leakproof floor Anti-sliping properties

Suggested types of gratings/load bearing bars and thickness of metal sheets:

X4KOZ/34.3×76.2	Bearing bar: 25×2, 25×3, 30×2, 30×2, 40×2, 40×3
X5KOP/33.3×66.6	Bearing bar: 25×2, 25×3, 30×2, 30×2, 40×2, 40×3
Tearplate	3 mm
