What is the Polka Plate?The plates that have dots made by the rolling for the anti-slip continuously on their surface are called “Checker Plates”.
PolkaPlate
CheckerPlate
Top of dot is flat.
The flat on the top of dot has an effect on anti-slip and cursoriality of cart.

Comparison of the ground contact area
The area of the Polka Plate in contact with the sole of shoesis larger than one of the checker plate.

【Welding】・The welding procedure for polka plate is not different from
checker plate’s .
・Flat area (base area) of polka plate is larger than one of checker plate. It makes it easier for the welding procedure.
【Bending & Cutting】・Flat area of polka plate is larger than one of checker plate, which could
be the advantage of any dimensions accuracy when bending and cutting.

To paint on carbon steel checker plate for refurbishment bridges the gap that exists between dots and makes it slippery.⇒ In case of stainless steel, Not necessary to
paint on their surface to prevent corrosion!
⇒ Improve work efficiency with not rattling along.(Polka could allow operation vehicle to run smoothly compared with standard checkered plate.)
