Redwood Shiplap Pressure Treated - Is this suitable for external Garage Timber Cladding..?

I am in the process to source timber cladding. I earlier used this item from B&Q.
https://www.diy.com/departments/planed-spruce-shiplap-cladding-l-3m-w-119mm-t-14-5mm/1013951_BQ.prd

'Planed Spruce Shiplap Cladding' above is costly so wondering if Timber merchant's  ' Redwood Shiplap Pressure Treated '  is better option..? Please help if you have any inputs..? Anyone previously used https://www.robinstimberdelivery.co.uk/?? Are they reliable..?

Thanks

Can't comment specifically on the product you have linked to, but local timber merchants are invariably better than the likes of B&Q. For a start, you can get longer lengths, and can usually negotiate on the price.

Much of the timber I've had from B&Q has twisted or cupped within days of bringing it indoors - About the only stuff I'll buy from there now is sheets of MDF & ply, but only as a last resort.

Pressure treated will be fine for exterior use. But I'd still give it a coat or two of preservative/stain on both sides before fixing it to the wall.
