About MEFA


Renz A/S develops, manufactures and markets mailboxes and mailbox systems of high quality and attractive design with a focus on security.

MEFA was established in 1969 but since January 1st 2017 our company is called Renz A/S. Renz A/S is part of the RenzGroup – Europes largest manufacturer of mailboxes, parcel boxes and mailbox systems – and our market leading position has been achieved through purposeful commitment to design, function and quality. Our focus in the market is with single-family and multi-family homes, apartment blocks, business premises and institutions.


The vision is to become the “World’s Best Supplier” of letter box solutions – within the Nordic countries!

We aim to continue to lead the way in understanding the needs of consumers. Our efforts shall result in functional, user-friendly products of high quality, whose design is in a class of its own.

Our goal is that the market in general shall consider MEFA products and solutions to be the most complete and well-thought-out available.

Based on this vision, we offer a wide range of products designed to suit everyday life and to meet the needs of quality-conscious international customers who wish to enjoy contemporary Scandinavian design.

We want our end users to feel that we have thought about how our products perform in everyday use and that we live up to our motto: “We take good care of your mail”! And we want our distributors to experience us as being a responsible and reliable partner in everyday relations.


All MEFA products, with very few exceptions, are produced in our own factories, where Lean principles help simplify and streamline all processes.
All our factories are located in Europe and close to our home market, which means we are close to the environments where our products are used. This also gives us a better understanding of the requirements for durability and functionality.

Our strong focus on mailboxes, parcel post boxes and accessories for these products means that throughout the company’s 90-year history, we have been able to optimize the quality of our products so that today they are among the best on the market.

In our fully automated painting line, where pre-treatment and powder coating take place in one step, we ensure the optimal quality and longest possible durability of painted items. Here we have the ability to paint in all RAL colors, even down to very small batch sizes, in fact, it can be done down to a single mailbox!

All our products are produced in pre-treated steel, galvanized or stainless steel, copper or aluminium. In the production of MEFA products, we do not use the somewhat cheaper black steel.

Alice Bigum

Alice Bigum

Alice Bigom trained at the Aarhus School of Architecture and is a partner at ‘ABO Plan and Arkitektur’ in Bergen, Norway. The daughter of a mailbox manufacturer, she grew up in Denmark.

MEFA Wave is designed as an antithesis to traditional, square mailboxes, inspired by waves and wind with a circle sector as its basic form. MEFA Wave was originally designed for the Norwegian market, but there was little interest in designer mailboxes in Norway in the 1990s, and the design of Wave was therefore completed in partnership with MEFA and introduced in Denmark in 1998.
Since then, MEFA Wave has gone on to becoming Denmark’s most popular designer mailbox!
