Standard Supports 2020
Standard Supports 2020 Date of issue: June 2015 The LISEGA product program covers all components required for the implementation of modern concepts in the support of pipe systems. These components correspond to the LISEGA standardization philosophy and are organized in a modular system with load and attachment compatibility. Containing the complete product program, this catalog is in full compliance with LICAD, the LISEGA pipe support design program. The catalog and LICAD can be downloaded from www.lisega.de. LISEGA reserves the right to introduce revisions in the interest of further technical development.

Performance with System
Customers and their suppliers depend on
each other for mutual success. We at LISEGA
want to show ourselves to be partners of
value to our customers with a comprehen-
sive and effective performance package.
We are prepared to provide top performance
day in and day out. Our goal is customer
satisfaction and only if we achieve that
objective are we satisfied too – that’s where
our motivation is coming from.
Right from the beginning, some five decades
ago, we have concentrated exclusively on
pipe supports, thoroughly and comprehen-
sively.
The quality and efficient utilization of our
products are just as important to us as
our reliability and low application costs. (from left to right)

For this, and for our mutual pleasure in seeking success, people at LISEGA are
working together with our customers, goal-orientated and highly motivated by
performance with system.

0.12.3 Principle of the optimum design
For the design and arrangement of support
components, optimum coverage of the specific
support function is the decisive factor. So only
one design is required for each function, namely,
