Many of the grate assemblies used in SPS basket trap floor wastes have been developed
with heavy-duty load applications in mind, for example supermarket loading docks.
Appendix 2 contains some examples of load tests carried out by
Pearl Street ETRS
of
Auburn (a NATA-accredited testing laboratory). These particular grate assemblies have
been tested to Class C of AS3996-2006.
