Metallbau Kirchberger is a very reputable and competent company. I had a special request, was well advised, and perfectly served. Despite being a custom order, delivery was very fast! I would choose them again anytime!

Kirchberger Metall can be highly recommended. Smooth process from inquiry to delivery. The delivery to Switzerland was also organized and handled to our complete satisfaction. Telephone contact with Mr. Kirchberger always worked perfectly. We are happy with our bike shed. Thank you, we can order here with a clear conscience.

After a long search, we discovered this shop. Great service, very friendly and competent advice. Top quality. When purchasing from the online shop, the various options are clearly displayed, which makes selection and purchase easier. Payment also possible via PayPal. The delivery announcement by the forwarding agent worked well. The window grille was carefully packed and delivered. We will definitely be ordering more window grilles here. Purchase August 2025; UPDATE: We have become repeat customers and bought another window grille from Kirchberger in November - absolutely satisfied - fits together perfectly.
