The Beamdeck system ensures fast forming and easy handling with three components: main beam, drophead, and crossbeam. This aluminum beam slab formwork system allows for early striking due to its integrated drophead. Because the main beam can be attached to either the drophead or another main beam, the system easily adapts to any application. A 7x7-ft. drop grid arrangement allows for fewer prop requirements and can accommodate slabs with up to a 10-degree incline. Peri Formwork. 410-712-7225.
