An outstanding range with outstanding performance
The ILB® system is a framing system that achieves massive
spans thanks to its unique design. The light weight nature
of the product means you will also reduce transport and
handling costs.
Whilst this product is a revolution in the building industry,
it is easy to use and fast to install.
There is a wide choice in the range. Whatever the need,
ILB® can supply a solution to overcome any design
or construction hurdle.

NOTES:
1. For ILB’s G350, fyf = 350 MPa and fuf = 430 Mpa; fyw = 300 MPa and fuw = 400 MPa
2. Comparisons based on BHP grade 300PLUS™
3. Stiffness equivalent is a direct comparison of Ix values and lightest weight alternative
4. Strength equivalent based on direct comparison of φMs and lightest weight alternative
