All Doco door components and garage door systems are designed and manufactured using the best and most sophisticated quality control tools.

Doco door components are designed in accordance with the latest rules and regulations,or stated otherwise. Dimensions, tolerances, material, function and finish are selected specifically for every product, so that every product has its own specification for use. With our sophisticated 3D modeling software we can make strength calculations (FEA analysis) which tells us how the product reacts to dynamic forces. These specifications are translated into production drawings and technical datasheets. These are used by our production facilities and secure the quality of the end product.When the first sample products are produced, they are tested and checked thoroughly at Doco’s main office in the Netherlands.
For specific tests we design our own testing equipment. This testing equipment simulates the use of the product in real life, ensuring durability and function. During main production runs, our own trained Doco quality control engineers carry out inspections during production and before shipment to our warehouse. When the products arrive at our central warehouse in the Netherlands, our quality engineer carries out a final product inspection to confirm compliance with the specification.
