Floor grating - heavy duty, common specs as following:
The load bearing bars are produced from steel which conforms to the following equivalent standards: AS3679 Grade 250, BS4360 Grade 43A and ASTM A36 or equivalent.
Serrated surface (serrated bar), banded with the same size flat bar (end banding type), hot dip galvanized.
The minimum average hot dip galvanized coating required by standards AS1650, BS729 and ASTM A123 is 610gms/sq metre (the minimum average thickness of galvanized coating must be 87.14 micron).
Width: 600 mm / 900 mm / 1200mm
Length: 1000mm - 1800 mm
Installation of Heavy Duty Bar Grating Floors:
The installation of heavy steel grating can be welding or folder installation. Welding fixed for the permanent position does not require demolition, such as equipment around the platform; and with the use of the installation folder does not undermine the zinc layer and the demolition of the characteristics of convenience.
Welding is fixed: usually at a flat 2 flat steel welding, weld length of not less than 20mm, not less than the high welding 3mm, the use of plane angle weld; if the grating or the span of particularly large particularly when the load above the need to strengthen the joints.
Installation folder is used for a variety of grating specifications.
Regarding saddle clip installation, at least four sets of saddle clips would be used in one pc grating. It would be better using more in the saddle for these bar grating with a bigger span.
