Horizontal Formwork with BTM Beams

he Horizontal Formwork with BTM Beams is a simple and BTM Beam 160: Tpractical system. Its few components and its ease of Mechanical application on site make it a fast and effective formwork characteristics. system. BTM provides slab formwork solutions, and it can be adapted to any layout encountered, whether working in small or large spaces. The BTM Beams 160 are easy to handle. Light weight and perfectly designed, they can be used to solve any construction site problems. The beams are protected on their extremes by covers, and they resist being damaged by hits and rough treatment common at the construction site. Galvanic protection provides rust-proof coating, resulting in highly durable beams.

Solutions offered by the system

Assembling the Bidirectional Head. The Bidirectional Head socket is installed on the Prop. One or two beams can overlap.

Assembling the Single Head. Only one beam can be installed per prop.

Assembling the Tripod. This permits setting the prop up vertically. It should be used at the beginning of the assembly.
