Spreader Bars - Galvanized vs Aluminium

[Agent009]

Hi

Will be setting up a tarp for 4 weeks over Christmas and just need to purchase a few spreader bars.

Can get galvanized ones for $16.95 each:

Or, aluminium ones for $27.50 each:

Is aluminium better or does it not really matter?

Thanks

Aluminium is certainly lighter and they don't rust. I've swapped all my steel poles for ally.

Not sure, but I got quite a shock when I searched "spreader bars" on Ebay................apparently there is a whole category of "devises for adults" on there called spreader bars
