Two states — two divisions. Same day — same goal. 🤜 🤛 🛏️ Teammates at Kirby Building Systems, Portland, TN, and Nucor Steel Kankakee Inc., Bourbonnais, IL, each recently participated in a build a bed event. Partnering with Sleep in Heavenly Peace, a non-profit organization that builds and delivers bunk beds to children who don’t have beds of their own, teammates exemplified living our culture by serving their local communities. 🌟
