Exemple : for the formwork of a slab 0.55 m thick, the design chart allows, for a common finishing, a span of up to 1m50 for MP3 beams. 1.50 1.50 0.55 Phal P1 beam MP3 beam Slab thickness (m) Max. span (m) To facilitate removing formwork, begin by shoring removal and installing an intermediate row of primary beams.
