Metal Deck J Closure Accessory

At D-MAC Industries, we supply J closure accessories to provide a clean, finished edge for steel roof and floor deck systems. Designed to seal gaps and reinforce structural integrity, our J closures ensure a professional finish while protecting against moisture infiltration and debris. These metal decking accessories are essential for achieving a precise, durable installation in commercial and industrial construction projects.

Applications for J closures

J closures seal open edges, preventing water, dust, and debris from accumulating in exposed gaps. By reinforcing structural stability, this metal decking accessory ensures a tight, secure fit between decking panels and adjacent surfaces, reducing the risk of movement or misalignment over time. Additionally, these accessories enhance both safety and aesthetics by providing a smooth, finished look to metal decking installations, creating a polished appearance while maintaining the integrity of the structure.

Materials Made to Strict Specifications

All D-MAC Industries products are manufactured within specifications outlined by the Steel Decking Institute (SDI) and are available in a galvanized finish for enhanced corrosion resistance. We can also custom-fabricate our metal decking and metal decking accessories in various gauges and dimensions to meet specific project requirements.
