Quality
Thought through properly from the start
At Erich Keller, quality does not begin in the workshop. It begins in the planning, in clear processes, in tested materials, in sound documentation and in taking responsibility for every project step. Our quality and environmental management system is certified to ISO 9001 and ISO 14001. It helps us to plan demanding interiors, workstations, room systems and climate solutions reliably, to manufacture them carefully and to deliver them under control.
Where quality becomes visible
Precisely planned. Carefully manufactured. Reliably delivered. Quality does not show only in surfaces, joints and materials. It also shows in whether deadlines hold, interfaces work, details are settled and a project is delivered as it was planned.
Certainty in planning
Clear processes, documented requirements and structured project handovers create certainty – for clients, architects, planners and internal teams.
Control in manufacturing
In Sulgen we combine craft knowledge with modern production, material expertise and controlled manufacturing processes.
Responsibility in delivery
Installation, documentation, testing and clear responsibilities ensure that quality is not only planned but delivered on site.
Quality needs clear processes
Erich Keller AG’s quality management system governs how processes are described, documents controlled, records kept and internal audits carried out. Quality therefore remains verifiable – and is continuously developed further.
Audited against recognised standards
Erich Keller works with a certified quality and environmental management system to ISO 9001 and ISO 14001. The certificates confirm that key processes are documented, audited and regularly developed further.
