You can always rely on the quality of our purlins and transoms. Based on our decades of experience, we have developed reliable processes that enable us and our motivated employees to manufacture products of the highest quality. Our customers benefit from our quality every day through products and services that meet the highest standards. We realise consistently high quality on the basis of modern machinery that reflects the current state of the art.
Purlins and transoms offer a high level of security
Cost-effective alternative to hot-rolled profiles
High dimensional accuracy thanks to innovative bending techniques
We ensure the well-known high dimensional accuracy of our products through a combination of state-of-the-art coil and punching systems and innovative bending techniques. We realise production lengths of up to 16,000 mm on the basis of safe processes. When it comes to materials, we rely on S390GD+Z/ZM steels. Our edge profiles have CE marking in accordance with EN 1090, and assembly-friendly packaging and labelling (positioning) of the profiles shortens the assembly work. We usually use material thicknesses from 1.75 to 4.00 mm. We are happy to process other material qualities and grades on request.

Purlins and transoms - Handbook for structural engineers
The technical catalogue "Purlins and transoms" provides structural engineers with all the information they need on lightweight metal construction with SCHRAG|edge profiles. Free of charge and without obligation. The handbook for structural engineers impresses with its wealth of detail and clear structure. From general information on our profiles to detailed forms for the preliminary dimensioning of roof purlins, wall transoms and eaves profiles, the compendium for edge profiles contains everything you need to plan your building project. The "Purlins and transoms" handbook is an aid to structural engineers in their day-to-day work and a valuable addition to a consultation with your personal contact.
FAQ - Frequently asked questions
Was kosten Pfetten und Riegel?
Pfetten und Riegel werden bei SCHRAG gesamtwirtschaftlich betrachtet. Angefangen bei der statischen Optimierung der Profilgeometrie und Einsatz der Verlegesysteme kalkulieren wir für das einzelne Bauvorhaben den besten Preis. Wir freuen uns auf Ihre Anfrage.
Gibt es Belastungstabellen für die SCHRAG Pfetten- und Riegelprofile?
Es liegen keine Tabellen vor, der Einsatz der SCHRAG-Profile wird jeweils auf das Bauvorhaben optimiert. Die Bemessung erfolgt mit der FEM-Methode.
Was sind die Vorteile von Koppelträgerpfetten?
Bei Gebäuden mit vielen Binderfeldern, großen Stützweiten und hohen Belastungen bildet das Koppelträgersystem einen Durchlaufträger. Durch diese statische Optimierung reduziert sich oftmals die statisch benötigte Materialdicke, was sich positiv auf die Kosten auswirkt.
