TATA Roof Deck D35

The D35 Roof Deck is a versatile option for lightweight commercial projects, spanning up to 1.5 to 2.5 metres. It uses overlapping sheets for efficient load distribution while remaining lightweight.

Supports typical loadings of up to 2.0 kN/m²

Comprehensive technical specifications, including Colourcoat options for enhanced durability and appearance can be downloaded, and our team is available to assist with site-specific calculations as required.

  • Developed for efficiency, aesthetics and structural performance.

  • Material Sustainability

    Recyclability: Steel components are 100% recyclable at the end of life.

  • Longevity: Durable galvanised coating provides extended service life

  • Acoustic insulation, enhanced by perforated edges and profile fillers, helping to reduce noise and improve interior comfort.

  • Aesthetically pleasing finish that complements various architectural styles and provides a clean, attractive finish.

  • Acoustic insulation, enhanced by perforated edges and profile fillers, helping to reduce noise and improve interior comfort.

  • Easy to handle for safer onsite logistics.

DESIGNED FOR

CONSTRUCTION PROJECTS

Features

Profile depth: 35mm

Cover width: 900mm

Pitch: 150mm (tighter rib spacing)

Trough width: 75mm

Bearing width: 65mm on purlin

Steel option: S280 in 0.7mm, 0.9mm, 1.2mm

Aluminium option: Rp0.2 165 in 0.90mm, 1.20mm (one-third the weight of steel)

Solid profile only (no perforated variant)

Benefits

Lightweight Aluminium Option

Aluminium variant weighs approximately one-third that of steel at equivalent thickness, easing handling and reducing overall structural load

Cost-Effective for Short Spans

Designed specifically for 1.30m to 2.80m spans, eliminating overspecification and material waste on shorter applications.

Tighter Rib Spacing (150mm)

More ribs per metre than deeper decks, providing better load distribution and reduced deflection for intermediate support layouts.

Applications

Building Types and Applications

The D35 system is ideally suited for lightweight commercial applications:

Lightweight commercial buildings

Industrial facilities with purlin systems

Steel for general use, aluminium for wet or corrosive environments. No need to switch to a different profile family.

TECHNICAL SPECIFICATION

Technical

Structural Performance Analysis

Span Range & Load Conditions

- 0.70mm Steel: 1.30m–2.00m spans (imposed load)

- 0.90mm Steel: Approximately 2.40m spans (imposed), suction to 2.80m multi-span

- 1.20mm Steel: Approximately 2.80m across most conditions

- Aluminium: Typically 1.30m–2.10m depending on gauge and condition

- Always verify actual span capacity against final design loads with technical data

Material Selection

- Steel S280: General applications, cost-effective, excellent strength-to-weight

- Aluminium Rp0.2 165: Coastal, industrial, or wet environments; one-third the weight of steel

- Both available with polyester, galvanized, or polyurethane coatings

- Specify coating durability based on environment (ZF275 for general use, higher for corrosive)

Bearing & Support

- Minimum 65mm bearing width on purlin flange

Supports must be level and properly aligned

- Use approved fasteners (purlin fasteners or pad fasteners per drawing)

- Ensure purlin spacing aligns with deck span rating

Deflection & Serviceability

- Imposed load: span/200 maximum

- Wind suction: span/150 maximum

- Tighter deflection control benefits waterproofing and finishes

- Check deflection limits when specifying liner trays in built-up systems.
