steel decking floor decking

# DEKZAC™ Steel Decking **Robust Steel Decking for Composite Floor Construction** **RKPEB DEKZAC™** is a robust trapezoidal steel decking profile designed to function as **permanent formwork and a reliable working platform during construction**. It is engineered to support dead and imposed construction loads and can be used with steel and reinforced concrete systems, including composite floor slabs. With a **51 mm rib depth, 960 mm effective cover width and 980 mm overall profile width**, DEKZAC™ provides an efficient structural decking solution for commercial, industrial and infrastructure projects. The profiled design helps streamline floor construction and can reduce the requirement for temporary formwork. Its **interlocking male and female ribs at the side joints** help provide continuity and structural integrity across the assembled deck. DEKZAC™ is available in different thicknesses and material grades, with **customized sheet lengths** to suit individual project requirements. ## Key Specifications * **Profile Type:** Trapezoidal Steel Decking * **Rib Depth:** 51 mm * **Effective Cover Width:** 960 mm * **Overall Profile Width:** 980 mm * **Approx. Rib/Pitch Dimension:** 316 mm * **Thickness Options:** 0.8 mm, 1.0 mm & 1.2 mm * **Material Grades:** 250, 350 & 550 MPa * **Sheet Length:** Customized as per project requirement * **Application:** Permanent formwork, composite floor systems & construction platforms ## Key Features ### Permanent Formwork DEKZAC™ acts as permanent steel formwork for concrete floor construction, helping reduce the need for conventional temporary formwork. ### Reliable Working Platform The decking provides a practical working platform during construction and supports construction activities when appropriately designed and installed. ### 51 mm Rib Depth The 51 mm deep trapezoidal profile provides structural depth and supports the load-carrying requirements of the decking system. ### Interlocking Side Joints Male and female rib arrangements at the side joints help provide continuity between adjacent decking sheets and contribute to the integrity of the assembled deck. ### Efficient Construction DEKZAC™ can help streamline floor construction by combining permanent formwork with a working platform, potentially reducing construction time and labour associated with temporary formwork. ### Multiple Thickness Options DEKZAC™ is available in **0.8 mm, 1.0 mm and 1.2 mm** thicknesses, allowing selection according to project requirements. ### Customized Sheet Lengths Sheets can be manufactured in customized lengths according to project requirements, subject to manufacturing, handling and transportation considerations. ## Applications DEKZAC™ steel decking is suitable for: * Composite Floor Slabs * Industrial Buildings * Commercial Buildings * Steel-Framed Structures * Multi-Storey Construction * Infrastructure Projects * Reinforced Concrete Floor Systems * Permanent Steel Formwork * Construction Working Platforms ## How DEKZAC™ Works DEKZAC™ is installed over the supporting structural framework and acts as **permanent steel formwork** during concrete floor construction. The profiled ribs provide structural depth and support construction loads, while the interlocking side joints help maintain continuity between adjacent sheets. Once installed, concrete can be placed over the decking according to the project’s structural design and construction specifications, creating a composite or reinforced concrete floor system as specified by the engineer. ## Material & Strength Options DEKZAC™ is available in material grades of: * **250 MPa** * **350 MPa** * **550 MPa** Available thicknesses include: * **0.8 mm** * **1.0 mm** * **1.2 mm** The appropriate thickness and material grade should be selected based on span, loading conditions, structural design and project specifications. ## Technical Data & Load Tables Allowable loads and span capabilities depend on factors including **decking thickness, material grade, span, support conditions and construction loading**. For detailed engineering information, refer to the applicable **DEKZAC™ Technical Data / Load Table**. ## Frequently Asked Questions ### What is DEKZAC™ steel decking?
