HR3 Insulated High Rib Roof System

With Nucor’s HR3 roof panel, you have an economical solution compared to field assembled high rib roofs. Your panels arrive in one piece, requiring a simple one-step installation. This 40” wide panel installs quickly by using a unique EPDM gasketed saddle washer. This washer allows you to fasten at the standing ribs, out of shed water.
