Type B Structural Steel Decking

Type B Structural Decking, also known as B-Deck, Wide Rib, or WR Decking, is a high-strength, corrugated metal decking profile designed for use in commercial and industrial roofing, flooring, and mezzanine applications. Featuring a wide rib design, Type B Deck provides excellent structural performance and support for various load-bearing requirements.

Type B Deck is often used in combination with concrete or insulation systems for enhanced structural integrity and fire resistance. It meets SDI (Steel Deck Institute) standards and is an industry-preferred choice for its balance of strength, weight, and ease of installation.
