hahaha, reminds me how I got my tank into my room. It's a really old tank that is 3/4 in (1.9cm) thick glass, that's 72in x 30in x 19in . ( 182.9 cm x 76.2cm x 48.3 cm) Really heavy, and only had four guys, we rested like 4 times traveling a distance of only about 50 feet (15.2 m). lol . Since it's an old tank, it weighs so much :-/ I would say over 500lbs... I think
Being in Malaysia. I would guess the floors are concrete. That a common thing I've seen with many countries in that area. The walls and floors are all concrete. You could build trucks for a living in one of those places and have no issues with overloading the floor.
