B-beam biasanya terbuat dari baja struktural dan digunakan dalam konstruksi dan teknik sipil. Web menolak gaya geser, sedangkan flensa menolak sebagian besar momen lentur yang dialami oleh balok. Teori balok menunjukkan bahwa I-section adalah bentuk yang sangat efisien yang dapat membawa beban lentur dan geser di bidang web. Di sisi lain, penampang memiliki kapasitas bantalan beban yang dikurangi dalam arah transversal dan tidak efisien dalam torsi yang mengandung beban, yang mana penampang struktural berongga sering lebih disukai.
