Do you want to speed up your next job using concrete slabs? Check out these precast slabs with integrated fire-rated ducts

by Brianna Crandall — March 12, 2018 — Conquest Firespray, a manufacturer of Flamebar coated fire-rated HVAC duct systems, announced that complete building solutions provider FINFROCK is inserting Conquest’s Flamebar ducts into its precast/prestressed concrete components during the manufacturing process.

FINFROCK’s patented DualDeck — a spanning member consisting of two form-finished concrete slabs joined together by a steel truss — has interstitial space to accommodate subsystems. After manufacturing, structural components are shipped to the site and assembled from foundation to roof in zones.

FINFROCK initially began designing and integrating plumbing and electrical systems into the components during manufacturing, but fire-rated shafts were installed after assembly of the building, driving up cost and risk.

Working closely with Conquest’s engineering staff, FINFROCK developed a system to insert Conquest’s Flamebar fire-rated ducts into the floors members, eliminating the need for fire-rated shafts. By incorporating the Flamebar fire-rated ducts during the manufacturing process in a quality-controlled, factory operation, the building owner is assured of a code-compliant system, while FINFROCK speeds the delivery of a complete building by combining its vertically integrated business model and offsite construction, says Conquest.

FINFROCK provides cost-effective, rapid delivery of various types of multistory buildings. By using 3D modeling design technology, and computer-aided manufacturing, FINFROCK fabricates state-of-the-art precast/prestressed concrete structural systems that incorporate key subsystems into the structural components. This is said to result in value for multifamily housing, hotels, office and mixed-use buildings, with early, accurate prices and guaranteed on-time delivery.

Conquest’s Dick McCullough remarked:

Conquest’s Flamebar ducts offer FINFROCK a feature that they had not been able to include in their building system until now. Working with Conquest, FINFROCK can now offer a system that is complete with pre-installed fire-rated ducts, increasing schedule certainty and driving down costs.”

Conquest Firespray manufactures and markets Flamebar fire-rated architectural and engineered duct solutions to contractors, engineers, and architects. Conquest has served HVAC mechanical and sheet-metal contractors since 1998. Conquest fabricates UL classified and Intertek listed fire rated rectangular and spiral duct systems at its Michigan Headquarters plant and in Miramar, Florida.
