Steel gratings consist of a series of bearing bars cross jointed by welding at various intervals with cross bars (twisted square bars, square bars, round bars, flat bars etc.), to form a kind of steel products with square lattices among them. Their main applications are drain covers, steelwork platform panels, and steel stair treads.

1, What standard can NJMM grating meet?
NJMM can fabricate steel grating accoding to the standards in different counties, such as China: YB/T4001.1-2007, USA: ANSI/NAAMM(MBG531), UK: BS4592 and so on.
2, What specification of the steel grating can NJMM fabricate ?
NJMM can fabricate any specification of steel grating available, both in inch description and metric description.
3,What are the most commonly stocked panel size?
The most common standard panel sizes are 3'x24,' 3'x20', 1000x6000mm,1000x5800mm etc.
4, what are the most commonly stocked bar sizes(height and thickness)?
The most common bars are 1"x1/8", 1"x3/16'', 25x3, 30x3, 32x3, 25x5, 32x5, 35x5, 38x5 etc.
5,Is a deflection chart or load table available for bar grating?
You can learn it at our catalog.
6, Whatis the difference between serrated and non-serrated bar grating?
Serration is done for slip resistance. It is grating which has the top surfaces of the bearing bars notched.
7, What finishes are offered on bar grating?
Bar grating comes in untreated, painted, hot dip galvanized.
