There are two types of standard steel bridge decks:
The 321 type steel bridge deck has a net width of 990 mm, a length of 3 meters, and a height of 105 mm.
The 200-type steel bridge deck has a net width of 1050 mm and a length of 3.048 meters. Because the 200-type bridge deck requires high load-bearing capacity, its height reaches 140 mm, which is higher than that of the 321-type bridge deck.
