What Are Edge Trims?
Edge trims, also known as slab edge formwork, are steel sections used to contain wet concrete during the pouring process on composite roof and floor decking projects.
They are installed around slab perimeters, openings, upstands, and deck edges to define the slab edge, maintain the correct slab depth, and prevent concrete overspill during installation.
At RMD Profiles, our steel edge trims are made to suit your deck profile, slab depth, and project layout, helping contractors achieve a clean finish, accurate detailing, and faster installation on site.
