OMTP is recognised for its expertise in creating openings. Thanks to its turnkey service, a stairwell opening is a simple formality. It is ideal when you need to move quickly from one floor to another without redesigning the space. The professionals will carry out the job following every essential procedure scrupulously. This meticulousness is absolutely vital, because cutting the opening means altering the load-bearing structure of the floor. Before work starts, the technician must carry out an initial diagnosis to determine whether the project is feasible. A thorough examination then checks the condition of the framework, which determines whether it can be modified.
On one of our sites in Neuilly-sur-Seine, we began by preparing the opening in the floor using an electric chainsaw and a specialist diamond-tool machine.
The technicians follow a layout predefined by the engineering office. This gives you a perfectly stable steel structure that the client has approved beforehand. HEB120 S275 steel trimmer beams and split twin beams are then used to form the reinforcement structure of the opening.
The beams are assembled with welds, splice plates and bolts. The beams and trimmer beams are connected using steel angle sections. For an impeccable finish, we end by applying anti-rust paint to all the steel parts. Cleaning is then carried out with great care. Thanks to our work, you get a completely clear, clean and well-designed space.
