Winkhaus. Always precise.

Our mission is to offer more than just high-quality products and system solutions.

“Always precise” is our claim:
As a member of society that actively takes responsibility for people and the environment;
As a top system supplier for window and door manufacturers and as a leading manufacturer of modern access control systems;
As an employer that expects performance and commitment and offers secure, sustainable jobs;

As a forward-looking company that sees the demands arising from the needs of the society of the future as an opportunity to gain a head start for itself and its customers;

As different as these demands may be, we have the self-assurance to make a promise to our customers and partners:

We will be precise, in everything that we do. That is as valid for products, as it is for our business transactions. This promise is globally valid. And we are so serious about this that you will find this promise right next to our name.

Winkhaus. Always precise.

Responsibility for people and the environment

Sustainable thinking and action have a tradition at Winkhaus. We continuously invest in efficient and resource-saving processes and technologies to meet the growing demand for our future-oriented quality products as well as our responsibility for the environment. We optimise delivery processes and shorten transport routes to reduce greenhouse gas emissions.

As a member of AUF e.V., we participate in the recycling cycle for aluminium residues. We also recycle steel, brass and plastic waste. Our energy management system is certified according to ISO 50001 and our environmental management system according to ISO 14001.

We have been using our proven multiple-use system for decades to reduce packaging waste. Our small load carriers are an important component in the responsible use of resources which our customers also approve of.

Since we are one of the few manufacturers in the industry to conduct electroplating ourselves, an important focus is on environmentally friendly, nickel-free processes: Our systems are state-of-the-art. We use our own laboratories to regularly check to make sure we comply with the legally prescribed standards at all times.
