Chelsea products begin with quality materials. We worked to develop the advanced compounds and enhanced formulations used in the production of Chelsea products. All Chelsea products are made with our special proprietary formulations to ensure the optimum product performance and durability.
Our work begins with these advanced materials and formulations. This is coupled with a total quality control program (TQM) that includes not only raw material and finished product inspection along with a comprehensive statistical process control program, but even the fabrication of all parts in fabrication dies to ensure proper fit and processing of every Chelsea window and door system.
Chelsea’s engineering and tool and die professionals maintain total control of both the design and manufacturing of the extrusion dies and calibrators used in the production of our lineals which enable us to maintain a high standard of quality throughout the extrusion process.
Chelsea extrusions pass the most stringent industry standards and are even certified through the industry’s latest and most comprehensive lineal certification and inspection program.
