Four generations.
One job:
Make it hold.
Four generations of the Winkler family. One job: make it hold. From a Berlin metalwork shop in 1904 to the world market leader in rail fastening for underfloor heating - we build the components that disappear into the screed and have to perform for the next 50 years. Manufactured entirely in Germany and Switzerland. Shipped to more than 30 countries.
The complete range.
From a single source.
U-Rails, staple systems, clips, holding pins, plastic bend supports - everything that goes between insulation and pipe. For residential buildings, industrial facilities, stadiums, driveways and airport runways. Designed and manufactured in Germany and Switzerland.
What we stand for.
Four short sentences – instead of a glossy mission statement.
Quality without shortcuts
Every component manufactured in Germany or Switzerland - to our specification, not to a price point.
On equal terms
Customers, suppliers, team - straight talk, no politics, no games.
Keep our word
A committed delivery date is the delivery date. If something changes, we tell you early - not after the fact.
Direct, not roundabout
No ticket queues, no corporate runaround. Straight to the person who can decide.
