"We have been working successfully with ZARGES for almost 6 years. The best possible quality has been delivered on time and economically priced and all our requirements have been fulfilled. ZARGES kit sets for internally equipping towers reduce the time required for the different work processes (purchasing, delivery, assembly) and thus also costs."

"We evaluate ZARGES tower interior fittings as follows:

  1. The section-wise packaging is highly appreciated by the customers, as Cimtas also manufactures and delivers the towers in sections.

  2. Deliveries and documentation must be agreed with the customer in order to avoid any misunderstandings.”

"What Reuther appreciates in the supply of complete tower interior fittings:
We get everything from a single source and have only one point of contact for the complete tower fitting, i.e. we have been able to reduce our procurement fixed costs. Previously, we had a large number of suppliers.
ZARGES is constantly improving and optimising its deliveries. Delivery section by section enables us to forward the consignments directly, without any further processing or additional effort, to the production department ready for installation.
Keeping to deadlines is a priority, and ZARGES keep to the delivery deadlines they agree to.
ZARGES is open to our needs and suggestions for improvement....”
