In fast-paced construction environments where structural performance, speed of build, and cost efficiency are all non-negotiable, Metal Decking Sheets from Astal Roofing Industries deliver on every front. Engineered for composite and non-composite floor and roof deck applications, our metal decking sheets are the preferred structural choice for multi-storey buildings, bridges, and mezzanine floor systems across India — used by structural engineers, EPC contractors, and project developers who demand reliable performance at every level of the build.
What Are Metal Decking Sheets?
Metal Decking Sheets — also referred to as steel decking or composite deck sheets — are profiled steel panels used as a permanent structural formwork and load-bearing base for concrete floor slabs. Once concrete is poured and cured, the decking sheet acts compositely with the slab, contributing to the overall structural capacity of the floor system and eliminating the need for traditional temporary timber or steel formwork entirely.
For structural engineers and project procurement teams evaluating floor systems for multi-storey or large-span structures, metal decking offers a compelling combination of structural efficiency, construction speed, and long-term cost performance — all in a single, factory-manufactured product.
Key Features & Technical Advantages
Precision Thickness Range
Range (0.80 mm – 1.20 mm): Available across a heavier gauge range than standard roofing profiles — engineered specifically to carry wet concrete loads during construction and contribute to composite structural performance post-pour, across a wide range of span and load configurations.
High Load-Bearing Capacity
The profiled steel geometry combined with high tensile base material delivers exceptional structural rigidity and load distribution — capable of spanning between primary beams without intermediate propping in many design scenarios, reducing temporary works requirements significantly.
Speeds Up Construction
Metal decking eliminates the need for traditional temporary formwork — reducing materials, labour, and striking time on site. Panels are lightweight enough for manual handling, cover large floor areas quickly, and provide an immediate working platform for follow-on trades as soon as they are laid.
Cost-Efficient
Corrosion-Resistant Finish
Available in Custom Sizes & Profiles
Applications
Multi-Storey Buildings
Bridges & Elevated Structures
Used as permanent formwork and structural deck in bridge construction, flyovers, and elevated walkways — where lightweight, high-strength decking reduces dead load on supporting structures while accelerating the construction programme.
Mezzanine Floors
An ideal solution for industrial and warehousing mezzanine installations — providing a strong, level working platform that can be installed quickly over existing ground-floor operations without interrupting facility workflow.
Why Source Metal Decking from Astal Roofing?
At Astal Roofing Industries, Metal Decking Sheets are manufactured at our precision roll-forming facility in Bengaluru’s KIADB industrial zone, using prime galvanized or galvalume coil processed to exact deck profile geometry. Each production batch is checked for profile consistency, coating integrity, and dimensional accuracy — so the decking that arrives on your project site is ready to lay without rework or adjustment.
We supply to structural steel fabricators, EPC contractors, and project procurement teams across India — with the capacity to handle large single-project orders and ongoing multi-project supply schedules. Our team provides specification support, load-span tables, and product data sheets to assist structural engineers during the design and procurement phase.
