Coque MD
DESCRIPTION
Designed for all types of building, the Coques MD shells underscore an architecture in which the façade is part and parcel of the expression of volume, with its flatness, curves and sequences.
Manufactured to measure from a defined client specification, the Coques MD system is perfectly suited to architectural invention.
APPLICATION
The MD shells are made of pre-lacquered galvanized steel, stainless steel or aluminium fixed by their vertical edges then blocked in place using brackets. The MD shells are designed for flat facades from 3 to 30mm maximum horizontal and vertical indented joints.
The fastening system is characterized by the fact that the fastenings are not visible in case of vertical joints (minimum 3mm) or in case of vertical indented joint from 15 to 30mm.
MD shells must be used in accordance with the specifications and requirements of the Professional Rules for the manufacture and installation of Metallic Cladding.
