Inner Strength
Inner strength reinforcements make roofs, walls and floors stronger with less weight.
Fire-rated roof decks are made lighter, stronger, truly monolithic with Keydeck Truss-T Subpurlins and Keydeck Reinforcement.
The cast-in-place material flows through the open webs of Keydeck Truss-T subpurlins. Result: a truly monolithic deck with the material bonded through the subpurlins. This makes the total deck section stronger. It is also lighter because there is less dead steel weight in the subpurlin. Keydeck reinforcement unrolls flat and the twist weave construction gives maximum bond with the deck materials. Keystone Steel & Wire also supplies the popular bulb-T subpurlins.

Keyweld reinforcement sheets save on steel; cut construction time, inspection time and labor costs with mechanical handling and placement.
Improvements in welded fabric equipment now make it possible to weld large steel sizes into large sheets to meet the reinforcing requirements of individual jobs. Steel sizes to %" diameter with 2" to 16" spacing in sheet-sizes up to 16' wide and 36' long. Just supply the floor plan and the concrete and steel reinforcing specifications. We will recommend the Keyweld weight, spacing and sheet size.
