Evergreen I-Beam

These opaque white polystyrene I-beams are precision-extruded to provide a consistent, authentic structural profile. They are an essential material for professional model makers, prop builders, and structural engineers looking to accurately replicate steel girders, roof trusses, and heavy-duty bridge spans in architectural models and industrial dioramas.

Manufactured from high-quality styrene, these structural beams offer exceptional workability for complex scratch-building projects. They can be easily cut or mitred to size using standard craft knives and bond seamlessly with plastic solvent cements for strong, rapid assembly. The smooth, neutral white surface provides a perfect base for priming, allowing makers to apply metallic paints or weathering effects to achieve a realistic industrial finish.

Supplied in manageable 350mm lengths, these I-beams are available in a comprehensive range of dimensions, spanning from delicate 1.5mm profiles up to robust 9.5mm girders. This extensive sizing ensures you can achieve exact scale matching for any creative build, whether you are focusing on fine detailing or constructing large-scale structural mock-ups.
