Steel I-Beam Free 3D Icon

A chunky steel I-beam in 3D, the kind of structural section you see in frames, warehouses, bridges, and construction diagrams. Useful in apps, presentations, or sites about engineering, fabrication, architecture, or building materials where a generic block will not do. It is free for commercial use, and on the free plan you just add a credit once.

Every Steel I-Beam detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is a 3D render, on a transparent background, with no mask to draw.

Common homes for it are product interfaces, feature illustrations, empty states and onboarding screens. Teams in consumer apps, e-commerce platforms and productivity tools tend to use it most.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
