TATA Roof Deck 159 provides a 750mm cover width
The TATA D159 Roof Profile is an advanced solution designed for robust structural roofing needs, offering versatility and performance for large-scale projects.
Aesthetic Options with Colourcoat
The TATA D159 can be finished with Colourcoat® pre-finished steel, offering a wide range of colours and textures for architectural flexibility.
This finish not only enhances the visual appeal of the building but also provides superior resistance to corrosion and weathering, ensuring a long-lasting, low-maintenance solution.
Depending on material thickness, the D159 can accommodate loadings of up to 7.5 kN/m², providing reliability under high live and dead load conditions.
Efficient Installation: Overlapping sheets streamline the construction process, saving time and resources.
Whether your project requires enhanced acoustic performance, high load-bearing capacity, or a visually striking finish, the D159 profile delivers on all fronts. Download the technical manual for comprehensive specifications or contact our team for tailored calculations and advice specific to your project.
Note: Available only in 1.2mm and 1.5mm gauges.
Watch this short video for a quick explanation!
The D159 profile optimises its load-bearing capacity through overlapping sheets, which enhances stability and reduces deflection. This feature allows for efficient structural design, minimising the need for additional support and expediting construction timelines.
Material Sustainability
Recyclability: Steel components are 100% recyclable at the end of life.
Features perforated edges and fillers for noise reduction and sound absorption.
Acoustic Performance and Finishes: For projects in noise-sensitive environments, the D159 profile can be specified with perforated edges and profile fillers, ensuring excellent acoustic insulation.
Premium deep structural deck engineered for demanding applications where exceptional long-span capability and load performance are essential.Easy to handle for safer onsite logistics.
Compliance with Design Codes and Standards (see technical).
DESIGNED FOR
CONSTRUCTION PROJECTS
Features
Depth 159mm • Cover width 750mm • Trough 38mm • Narrow flange 108mm • Pitch 250mm • Bearing 100mm
Benefits
Exceptional Span Capability
Solid D159 spans up to 9.00m – the longest span in the core RoofDek range
Perforated variant spans up to 8.00m whilst maintaining acoustic benefits
Reduces intermediate column requirements, freeing internal floor space
Material Flexibility for Demanding Sites
1.25mm Steel S320 for maximum rigidity in severe load conditions
1.50mm Aluminium Rp0.2 165 (thickest aluminium in the RoofDek range) – less than half the weight of steel
Aluminium option reduces self-weight on long spans, lowering support structure costs
Acoustic Control Options
Web perforated pattern 3327 (27%) – same as D137 – controls reverberation in large public spaces
7.6% open area on exposed soffit (14.2% of cover area) balances acoustic performance with structural integrity
Suitable for concert halls, exhibition centres, and sports venues
Deep Profile Design
159mm depth is one of the deepest profiles before the D200
Extreme moment of inertia supports long-span loads with minimal deflection
Professional appearance for exposed ceilings in major venues
Applications
With spans up to 9.00m in solid form, the D159 is the solution for distribution centres, aircraft hangars, industrial sheds, exhibition halls, and major sports venues that demand uncompromising structural integrity.
TECHNICAL SPECIFICATION
Technical
Deflection Limits
Imposed load: Span/200 • Suction load: Span/150 • Industry-leading stiffness-to-weight ratio
Aluminium Advantage
1.50mm Aluminium weighs only 7.97 kg/m² vs 19.19 kg/m² for steel – moment of inertia 846.31 cm⁴/m (higher than steel) due to thicker gauge
Limited Material Options
Only 1.25mm S320 steel and 1.50mm Aluminium Rp0.2 165 – reflects the specialist structural demands that thinner gauges cannot meet
