In the world of modern construction, deck sheets are more than just panels placed beneath concrete slabs or roofing layers—they are structural components that dramatically affect speed, safety, cost, and performance. At Bansal Roofing, based in Vadodara, Gujarat, deck sheets are one of the core product offerings, engineered for strength, durability, and efficiency. Here’s an in-depth look at what deck sheets are, their benefits, types, how to choose them, and why Bansal Roofing is a reliable manufacturer and supplier.
What Are Deck Sheets?
Deck sheets are cold-formed metal sheets (commonly steel) used in construction as permanent formwork (also called permanent shuttering) below concrete slabs or roofs. They serve multiple functions:
- Acting as a structural component that supports fresh concrete until it cures.
- Reducing or replacing temporary formwork.
- Serving as part of the finished structure, contributing to strength, load-bearing, and usable surface.
Why Deck Sheets Are Important
Deck sheets are not just optional—they bring measurable benefits in many construction scenarios. Here are key advantages:
- Composite Member & Permanent Shuttering
The deck sheet functions as a permanent form (shuttering) and becomes part of the slab’s composite structure. That means less temporary support is needed, speeding up the construction schedule. (Bansal Roofing) - Working Platform
During construction, deck sheets can double as safe working platforms. This reduces risk and allows other trades (masonry, electrical, etc.) to begin work sooner. (Bansal Roofing) - Time and Cost Savings
Because formwork, labor, and reinforcement needs are reduced, total project cost comes down. Also, faster construction timelines reduce financial overheads. (Bansal Roofing) - Precision & Standards
Bansal Roofing designs its deck sheets with high precision to meet market and structural standards. Thickness, strength, width, support values—these are all thoughtfully determined so that deck performance is reliable. (Bansal Roofing) - Material Properties
The sheets are corrosion resistant (steel coatings or aluminum depending), lightweight relative to strength, and non-flammable—important in many climates and building types. (Bansal Roofing)
Types of Deck Sheets & Material Options
Deck sheets vary in many parameters: material, thickness, profile, and application. Bansal Roofing provides or references several relevant types and features:
- Base Material: Steel sheets are common; aluminum is also used in some cases. Bansal’s deck sheets are steel-based with thickness options between 0.80 mm to 1.50 mm. (Bansal Roofing)
- Profiles & Rib Depths: The shape, ribbing, and corrugation (if any) affect structural load capacity, stiffness, and composite action. Specific numbers available in Bansal’s product data (e.g., cover width of ~953 mm for certain steel deck profiles). (Bansal Roofing)
- Composite vs Non-composite: Composite decks work with concrete so that the slab + deck act together structurally; non-composite are more basic, sometimes used only for roof decks or temporary support. Bansal discusses composite slab decks in its blogs. (Bansal Roofing)
- Specialty Decks: For green buildings, acoustical decks, decks with specialized coatings, etc. Bansal also mentions being able to customize deck profiles. (Bansal Roofing)
Bansal Roofing’s Deck Sheets: Specifications & Offerings
Here are some of the specific technical details and product features Bansal Roofing advertises for their deck sheets:
| Specification | Details |
| Thickness | 0.80 mm to 1.50 mm for steel deck sheets. (Bansal Roofing) |
| Cover Width | For example, certain steel decks have a cover width of ~953 mm. (Bansal Roofing) |
| Load & Section Properties | Bansal provides full-section properties, moment of inertia (Ix), top and bottom in compression values etc. This is useful for engineering design. (Bansal Roofing) |
| Strength & Material Grade | Steel base metals with appropriate alloys/coating. Aluminium options also mentioned in broader product lines. (Bansal Roofing) |
Additionally, Bansal Roofing has invested in equipment to support deck sheet installation—including a shear stud welding machine which allows stronger fixing of the deck sheets to the steel structural members. This enhances load-bearing capacity, helps with stability, and improves safety in construction. (Bansal Roofing)
How to Choose Deck Sheets: Key Considerations
If you are selecting deck sheets for your project, here are some criteria to consider, based on Bansal Roofing’s offerings and general engineering principles:
- Load Requirements & Span
Assess the loads (dead load + live load + services) the deck plus slab will need to support. Depth and profile of the deck must match these loads. - Thickness & Material
Higher thickness often correlates with better strength but more cost and weight. Balance is needed. Coatings or material choice (steel vs aluminum) affect durability, performance under corrosion, etc. - Composite Action
If composite action (deck + concrete acting together) is desired, ensure proper profile and features (shear connectors, etc.) are available and installed correctly. - Speed & Construction Schedule
Deck sheets that can serve dual purpose (formwork + working platform) reduce labor and time. Also consider ease of transport, installation methods. - Environmental / Weather Conditions
If the building is in a humid, corrosive or chemically aggressive atmosphere, select coatings or materials accordingly. Fire safety, non-flammability may also be important. - Cost vs Lifespan
Upfront cost is important, but so is life cycle cost: maintenance, durability, replacement. Bansal Roofing’s decks’ material properties aim to offer long life with lower maintenance. (Bansal Roofing)
Real-World Applications & Use Cases
Deck sheets are used across many types of projects:
- Industrial and Commercial Buildings: Where large spans are needed, and speed is essential, deck sheets help in slab construction and roofing.
- Multi-storeyed Structures: Composite decks reduce overall slab depth, reduce loads, and allow faster staging of floors.
- Infrastructure Projects: Bridge walkways, concrete bridges, or platforms where permanent formwork and strong fixing are essential. The shear stud welding machine at Bansal Roofing helps in such heavy duty use. (Bansal Roofing)
- Green Buildings / Sustainable Projects: Decks with coatings, material options, and designs that reduce concrete volume or improve thermal performance help in achieving sustainability goals. Bansal Roofing mentions deck sheets in the context of green building design. (Bansal Roofing)

FAQ
Q: What thicknesses are available for deck sheets, and how do I choose?
A: Bansal Roofing offers steel deck sheets in thicknesses ranging from 0.80 mm to 1.50 mm. (Bansal Roofing) Choosing the right thickness depends on expected loads (dead and live), span length, whether you need composite slab behavior, and whether the deck also doubles as a working platform. Engineers will often calculate bending, deflection and load to decide thickness.
Q: What is the cover width of deck sheets from Bansal Roofing?
A: One common cover width in Bansal’s specification is 953 mm for certain steel decks. (Bansal Roofing) “Cover width” refers to the effective usable width when installed (i.e. how much width contributes structurally and how much overlap/laps are needed).
Q: Are deck sheets suitable for use as permanent formwork?
A: Yes. Bansal Roofing’s deck sheets are designed to serve as permanent shuttering (formwork) which remain in place after concrete is poured. This eliminates the need for temporary formwork and reduces time and labor. (Bansal Roofing)
Q: How does Bansal Roofing ensure that the deck sheets are structurally safe and meet standards?
A: The company provides full section properties (moment of inertia, compression in top/bottom, etc.) for their deck sheets. They maintain high precision in manufacturing to ensure that design parameters are met. Also, they have invested in installation support technology such as shear stud welding machines to ensure better fixation to structural members. (Bansal Roofing)
Q: What are the cost trade-offs when selecting deck sheets?
A: While deck sheets may cost more upfront compared to basic formwork materials, the trade-off is in saved labor, reduced reinforcement (in composite slabs), reduced temporary shuttering costs, faster construction schedule, and lower maintenance over time. Also, selecting higher thickness or better material/coating increases expense but gives longer lifespan and better performance. Bansal Roofing emphasizes precision so you don’t over-spend or under-build. (Bansal Roofing)
