Profile: Studwelders Composite Floor Decks Ltd. specializes in the design, distribution and installation for steel floor decking systems. MetFloor® 55 is a traditional dovetail re-entrant composite floor deck. Its profile provides a mechanical key into the concrete slab, offering a strong shear bond performance augmented by stiffeners located in the profile trough. It presents a virtually flat soffit and a relatively thin slab is required to meet fire design requirements. We supply a range of studwelding products including standard size plain and threaded anchors.
