Could it be used to withstand the weight of two people? Serious to make a bunk bed

They are strong to be fair but would think the longer the length the more likely they would sag - I used them to make a pair of trestles and have had up to 500kg on them

How many lengths do you get for the price?

Only 1, best to find your local metal supplier as it will be a lot cheaper
