be rest assured RaaArtyGunner
1. The deck is high tensile aluminium plate to AS Wopply Wop & the anti-skid ablative coating is only stained...by the metallic rust from above
2. I understand that the lower steel plate structure of the electro/hydraulic hoist [which is depicted with surface corrosion]
is from AS ....Grade 350 plate & with a 4:1 FOS on yield in the Naval design Standards = 1400 Mpa stress within the structure prior to failure
The structure if maintained........
will never fracture or fail..............Derek
