IPN beams

Sizes variants and definitions to generate IPN-like beams.

Example:

from db_beams_and_bars.ipn import Standards, Section, Bar

Section(Standards.IPN.IPN_80)
Bar(Standards.IPN.IPN_80, 1000)

All classes in this module are based on this sketch:

Hot rolled IPN beams

Matter: S275JR
Standards: NF EN 10024; EN 10365:2017

Usage

from bd_beams_and_bars.profiles.ipn import Section, Bar, Standards

# Create a section:
section = Section(Standards.IPN.<variant>)

# Create a beam (3d model):
beam = Bar(Standards.IPN.<variant>, 1000)
