[UT] Plasma Torch vs. big metal door on a spaceship?

• Am I missing a rule about torches doing corrosion damage instead of burning when focusing on a single section of a hull/wall/door/etc.?
• If not, how does one cut down through metal armour and doors, since those tend to have non-ablative DR that increases with thickness.

Thanks in advance!

Basic Set p.559:
"Repeated impaling, piercing, and large
piercing attacks against the same small spot
(an area with SM 0 or less) lower DR at that
specific point as if it were semi-ablative;
repeated burning, corrosion, crushing, cutting,
or huge piercing attacks at that same spot
reduce DR at that point as if it were ablative."
