Hi-Rib Roofing System
     
 
  • Trackdek® Hi-Rib provides the feasibility for variety of finishes for attractive roofing and cladding of Domestic, Commercial & Industrial Applications.
  • The patented fluted side lap makes TRACDEK® Hi-Rib Completely water tight. Any moisture drawn in by capillary action is trapped and dispersed by normal run-off.
  • Long Lengths and weather proof side lap allows TRACKDEK® Hi-Rib to
    be used safely on roof pitches as low as 3 degree (approx. 1 in 20) in single sheets length & 5 degree (approx. 1 in 11) with end laps, and for vertical cladding.
  • This Profile provides versatility and creativity to bring new and refreshing design to commercial, industrial and domestic buildings
  • It is also available in crimp curved sections and can be given curvatures.

Technical Specification Standard Execution
  • Wind Loads determined for Trackdek® are in accordance with IS - 875 (part 3)
    - 1987 for regional wind velocity of 47 m/s for buildings up to 10 m high in
    terrain category 3 and assuming an internal pressure coefficient of +0.2.
  • Support spacing for roofs are generally governed by foot traffic for low pitch
    roofs and by wind loading for high pitch roofs.
Benefits of Trackdek® Hi-Rib
  • Long Life: It is manufactured with High Quality Galvalume Steel. The high performance organic coatings give Trackdek® long life even in Coastal areas
  • High Strength: Tracdek® profiles provide excellent spanning ability and remarkable recovery after excessive load
  • Economical: The long spanning ability and more coverage per unit mass permits wide support spacing, enabling supporting structure economies.

Interarch Contribution to the Environment: Life cycle assessment (LCA)
     
  A life cycle assessment (LCA) can help avoid a narrow outlook on environmental, social and economic concerns by assessing a full range of impacts associated with all cradle-to-grave stages of a process: from extraction of raw materials through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. Impacts taken into account include (among others) embodied energy, global warming potential, resource use, air pollution, water pollution, and waste.

In terms of green building, the last few years have seen a shift away from a prescriptive approach, which assumes that certain prescribed practices are better for the environment, toward the scientific evaluation of actual performance through LCA.

Although LCA is widely recognized as the best way to evaluate the environmental impacts of buildings (ISO 14040 provides a recognized LCA methodology), it is not yet a consistent requirement of green building rating systems and codes, despite the fact that embodied energy and other life cycle impacts are critical to the design of environmentally responsible buildings.

“Delivering Value”: Life Cycle Cost advantage with Pre-Engineered Steel Buildings: By - Vikas Kaushal, Vice President-Marketing, Interarch Building Products
     
 

The performance of an industrial building is measured in terms of its life and the protection it provides to the
occupants from weather conditions so as to enable the factory operations to run continuously without any interference of weather effect such as rain, wind etc. Periodic maintenance is therefore required to keep this performance intact over a period of time. This maintenance involves water proofing in case of RCC Slab flat roof buildings, replacement
of damaged sheets in case of conventional steel truss sloped roof structures with Asbestoses cement corrugated (ACC) sheets Or replacement to Corrugated galvanized steel (CGI) sheets which have corroded due to action of weather.
Therefore over the Life of a building which is considered approximately 50 years, the Life cycle cost of the building is
calculated as follows:

Life cycle cost = Initial Construction cost + Periodic Maintenance cost

Even if we assume the initial cost of construction of a Pre-engineered steel building and conventionally site fabricated steel structure or a RCC building as the same, Life cycle cost of a Pre-Engineered Buildings is much lower. This is due to very low maintenance requirement in a Pre-Engineered Steel Building System as compared to conventionally site fabricated steel structure with an asbestos cement (AC) roofing sheet or a locally procured corrugated galvanized iron (CGI) sheet OR even RCC Slab casted flat roof building which requires annual water proofing within few years of construction.

Pre-engineered steel buildings as a standard are provided with very high quality steel roofing
and wall cladding cover in form of, profiled sheets manufactured out of high tensile strength, Galvalume steel coils. Galvalume is a special protective coating of Aluminium and Zinc alloy (AZ 150 - Coating Class) which enhances the life of steel by 4 to 5 times against life to first maintenance.
  • Galvalume steel roofing profiles are sold with a 15 years warrantee of life to first maintenance against corrosion.
  • As the buildings are detailed by experienced professionals, Pre-Engineered Building Companies give in an average 10 years warrantee against leakages from roof.
  • Galvalume Steel sheets are 50% lighter in weight (4 Kg/ Sq. M) as compared to Asbestoses cement sheets (8 Kg) therefore reducing the overall dead weight on the roof structure.
