Pontoon Bridge Design
The erection of steel structure pontoons, as a temporary means of transportation, is generally for the purpose of passing through the army and carrying heavy equipment. Sometimes it is also used to block the actions of the opposing navy. There are troops stationed on the pontoon bridge, and the pontoon bridge is used to fight against the opposing navy. At this time, the pontoon became a trench on the water. Great Wall Heavy Industry has extensive experience in the production and erection of steel structure bridges, and its products are exported overseas.
