Decking Sheet Product
Super Deck (DS-953)
I&I Engineering Infra – Super Deck (DS-953)
I&I Engineering Infra specializes in the design, manufacturing, and installation of high-performance profiled metal decking systems for industrial, commercial, and infrastructure projects.
To meet the increasing demand for composite steel–concrete floor systems in India, I&I Engineering Infra offers Super Deck (DS-953) – an advanced composite metal decking solution engineered for structural efficiency and long-span applications.
Product Overview
Super Deck (DS-953) is a cold-formed corrugated steel sheet system supported by steel joists or beams. It is designed to support reinforced concrete slabs or roofing insulation systems.
The deck features specially engineered embossments and integrated shear bonding mechanisms that ensure strong interlocking between steel and concrete, creating an efficient composite floor system.
Also referred to as a Composite Deck, Super Deck functions as permanent formwork during concrete pouring while contributing to the structural performance of the slab after curing.
This long-span composite system combines:
The speed and strength of structural steel
The durability and load-bearing performance of reinforced concrete
Technical Characteristics
Cold-formed high-strength steel profile
Engineered embossments for enhanced steel–concrete bond
Optimized rib geometry for structural efficiency
Designed for roof and floor applications
Suitable for multi-storey and industrial structures

Load Capacity
The structural performance of I&I Engineering Infra – Super Deck (DS-953) composite slabs is evaluated in accordance with recognized standards such as BS 5950 Part 4 and Eurocode 4 (EN 1994-1-1) for composite construction.
Due to the engineered shear bond developed between the concrete and the embossed metal decking profile, excellent load capacities of up to — and in certain configurations exceeding — 15 kN/m² can be achieved.
Super Deck systems typically utilize slab depths ranging from 130 mm to 200 mm, incorporating light mesh reinforcement for crack control and fire resistance.
Where higher structural demands or exposure conditions exist, additional reinforcement can be integrated to enhance load-bearing performance and durability.
Shear Studs in Composite Construction
In composite floor systems, hot-rolled steel beams act compositely with the concrete slab to create a high-strength structural unit.
To ensure effective force transfer between the steel beam and the concrete slab, shear studs are installed. These studs are typically welded directly to the steel beam, usually through the metal decking sheet.
Once the concrete has cured, the slab acts as a compression flange to the steel beam, significantly increasing the load-carrying capacity and stiffness of the composite section.
Installation Requirement
For proper structural performance, shear studs must extend a minimum of 35 mm above the top of the main rib of the deck profile after welding.
This ensures effective anchorage and optimal composite action between steel and concrete.
