I don't mind admitting: I've never "gotten" banding.
(OP)
It may be a bit embarrassing for a engineer to admit it at this point in his career......but I was looking at a grating shop drawing today and thinking to myself: "what does the banding/toe plate really do as far as load transfer goes? Does it run load from the weak axis of the grating to the strong axis? How do you check it? With the banding as a beam or more as shear transfer element? Are there good rules of thumb for opening sizes [with respect to this]?"
Any insight is welcome.

But construction and maintenance savings can't be the real reason for banding - after all, construction and maintenance are not high concerns any other time of the design and purchasing process. 8<)

This makes the toeplate at least 5-inches tall 'deep', and it can carry significant loads. I have every other grating bar welded to the toeplate at grating penetrations. This will carry the deck load around penetrations up to about 2-ft in diameter.

#2 They do tend to keep people from rolling under the mid rail - though not always.
Had a tragic accident a few weeks ago near the St. Louis area. Welder was welding guard rail post on a tank. Temp was over 100F.
He apparently passed out and rolled under the mid rail 50' to his death. He may have had a heart attack.
No toe board had been installed yet.

Im in the states and typically weld toe plate to handrail posts.

Banding around the edges of a section of grating keeps the raw, cut ends of the grating bars from being a snag hazard. It also makes sections of grating easier to remove and reinstall.

Toeboards are to prevent tools and materials from falling on to people or equipment below, or into hazardous operations. They are not part of a standard railing as required for all elevated walking and working surfaces. I think it is a terrible oversight to allow upwards of 20" between the floor and mid rail on a 42" high standard railing.
Below is excerpted from osha.gov:
1910.23(c)
"Protection of open-sided floors, platforms, and runways."...
1910.23(c)(2)
Every runway shall be guarded by a standard railing (or the equivalent as specified in paragraph (e)(3) of this section) on all open sides 4 feet or more above floor or ground level. Wherever tools, machine parts, or materials are likely to be used on the runway, a toeboard shall also be provided on each exposed side.
and
1910.23(c)(3)
Regardless of height, open-sided floors, walkways, platforms, or runways above or adjacent to dangerous equipment, pickling or galvanizing tanks, degreasing units, and similar hazards shall be guarded with a standard railing and toe board.
and
1910.23(e)(4)
A standard toeboard shall be 4 inches nominal in vertical height from its top edge to the level of the floor, platform, runway, or ramp. It shall be securely fastened in place and with not more than 1/4-inch clearance above floor level. It may be made of any substantial material either solid or with openings not over 1 inch in greatest dimension.
Where material is piled to such height that a standard toeboard does not provide protection, paneling from floor to intermediate rail, or to top rail shall be provided.

Intermediate banding also provides lateral restrain and spreading of foot loads across several 'beams'.
