BANDING OF GRATING
Banding is the most extensive manual labor in
the process of manufacture of steel grating , it is the biggest obstacle of grating intelligent manufacturing.
What is the banding, in the end edge grating, bearing
bars end is fixed with the flat bars.one purpose is to decorate the effect, another objective is transfer the load of grating to supporting structure by banding bar.
We put the former called trim bands, the latter is called the load-carrying bands
After cutting the steel grating can be welded or bolted clips or jet nails,etc.directly fixed on the supporting structure, does not need the bands.
Unless specifically ordered otherwise ,manufacturers
will not be
A band which carries no load , but is used chiefly to
improve appearance. is called trim bands.
Trim banding not need every bars to welding, and do not have full welding.
method can be resistance welding, arc welding, gas welding, brazing,
Under the bearing bars no support,only rely on the banding bars to transfer grating load to the supporting structure.
it is load-carrying bands .
The load-carrying bands must be able to accept and transfer the weight of grating and external load,in order to prevent accidents, must each bearing bars are welded,
and to be operated by skilled welders are qualified after examination.
If use the L type or Ctype sections to banding (Angle or channel), can be band in accordance with of trim banding.
