Design & Installation Process

In the initial stages, IIPG (Innovative Infrastructure and Products Group) conducts a comprehensive design analysis to provide clients with an estimated cost. This analysis considers factors such as building span, center-arch height, live load, wind load, dead loads, and the corrosive characteristics of the intended site. The data derived from this analysis is instrumental in determining the thickness of the steel roofing sheet and arch-reactions at beam levels.

Following the design analysis, IIPG furnishes the customer with conceptual design drawings of gutter beams, which may be constructed from concrete or steel. The arch-reaction data is then integrated into the structural consultant’s work, guiding the design of foundations, footings, columns, and beams. Subsequently, the customer proceeds with the construction phase, opting for either reinforced concrete (R.C.C) or steel structures.

Once the site is prepared with the supporting structure, IIPG conducts a thorough inspection and coordinates the transportation of necessary materials, including coils and mobile panel forming machinery, cranes, and seaming equipment tools and tackles. High-grade structural coils (Galvalume Coils) are fed into the mobile coil forming machine, producing the required length and curve deflections in interlocking profiles.

The profiled curves are then lifted and installed by cranes, fastened with Galvanized or Stainless Steel (SS) Anchor bolts onto the supportive concrete or fabricated steel beams along the eaves. The self-supportive, truss-less roofing system can be customized during the profile forming process to incorporate hangers, providing additional support for cable tray ducts, false ceilings, and light fixtures.
