The TÜV certification at Tuinmaximaal applies exclusively to the aluminium load-bearing structure of our patio roofs.
The production of these beams and posts is supervised by TÜV NORD and complies with the European standard EN 1090-1.
This certification does not apply to the entire patio roof, but it does guarantee the structural quality of the load-bearing components.

We consider the coating, used by Gumax, as the most suitable for the Excellence products offered, due to the reliability of the brand AkzoNobel – Interpon, in combination with the long lifespan.

Only the Gumax Excellence products will assure you of superior coating. 

We have heard that products, such as Mavro Nitoshield, can be used for maintenance, improvement and recovery of gloss of aluminium parts that were fitted with powder coating. For more information, including proper application and the safety regulations, we refer to the suppliers of the specific product. We do not accept responsibility for consequences of the purchase / usage of the specific product.
