Trussless arch roofing has brought a revolutionary change in the construction industry. This innovation is an American expertise proven and applied in over 60 countries over the last 30 years. Its durability, design efficiency, and cost-effectiveness are some of the factors making it an unavoidable part of an industry. Apart from the traditional roofing methods, these self-supported structures reduce the need for trusses, enabling broader spans without compromising stability. This makes them ideal for warehouses, industrial units, sports complexes, and even modern architectural projects in Kerala, where efficient use of space and aesthetics are key priorities. In an all-steel construction, the flat panels can also be utilized for side-wall and gable-end cladding.
Modern trussless roofs utilize advanced engineering techniques, including computer-aided design (CAD) software, ensuring that roofs meet safety standards against wind, seismic activity, and other environmental stresses. The panels fabricated are used for roofing that requires no trusses, purlins, or ancillary supports for up to a single span of 36 meters. These systems incorporate eco-friendly materials, aligning with the growing trend of sustainable construction in Kerala. These roofing and cladding panels are manufactured from superior-quality, structural-grade steel using state-of-the-art mobile panel fabrication equipment. Features like skylights, ventilators, and modular panels are often integrated to enhance functionality and reduce energy consumption.
The cost of arch roofing in Kerala varies based on materials, design complexity, and the scale of the project. Factors like customizations, the use of imported materials, and additional features such as thermal insulation or soundproofing can further influence the price. We Proarch, provide tailored solutions, that cater to both budget-conscious and premium segments. Contact us to get a rough idea about the expense.
Proarch Roofings is designed to suit more than 20 different Building Codes from all around the world, of which, a few recognized ones are listed below:
Proarch Engineering uses specialized Design & Engineering software to do a calculative study of Proarch roofing. According to ASCE 7-02, the International Building Code 2002, and BIS, this program factors the load parameters. The technology provider's design software has handled parameters such as cyclones, earthquakes, wind speeds, live loads, etc., and data has been input in accordance with the current IS requirements in that area. The maximum wind speed in each zone is taken into account while designing roofs in accordance with the National Building Code. The design takes into account a safety factor of 1.8 times. This provides sufficient resistance to uplift forces produced by gusts of wind.
Taking into account the necessary live load, wind load, dead load, and seismic component, the analysis is performed for the specified span and central arch-rise. The study establishes the arch responses at the beam level as well as the steel thickness. The consulting engineer then uses this information to design the building's beams, columns, and foundations. Based on the bolt's and the steel's uplift and shear capabilities, the number of fasteners or bolts per end of the panel is decided. This unique design and engineering software saves a significant amount of time and money when choosing the most cost-effective arch structure arrangement. The program modules will guide the designer through the examination of the arch structure in a methodical, menu-driven process. In contrast to traditional design processes, which could have taken two to three weeks, an arch structure can be designed in roughly five minutes using our Design & Engineering software.
It should be mentioned that the consulting engineer will use the structural data derived from this analysis to build the necessary structure and determine whether it is stable enough to support the loads coming from the roof.
Investing in high-quality arch roofing is cost-effective in the long run due to its low maintenance and high durability. With Kerala’s focus on modern infrastructure and sustainable practices, arch roofing has become a popular choice for both residential and commercial constructions. This technology's seamless blend of form and function ensures that it remains a top contender in Kerala’s evolving architectural landscape.

For reliable and cost-effective trussless arch roofing solutions, contact Proarch Engineering today. We have professionals who can assist you in designing and installing the perfect trussless roofing system for you.
1.This roll-forming equipment shall be placed inside the factory shop floor of a predetermined size for an efficient manufacturing and maneuvering of panels (this shall depend on the size of an individual panel & working area requirement). This equipment requires a flat, leveled and a solid-compacted surface so that it can be properly aligned. Hence the building contractor shall cooperate with Proarch roofings provider and their Project / Site Engineers.
2.There will be a labor force of approximately 25-30 people involved in the manufacturing process, depending on the length & weight of the panel. This involves all the activities pertaining to the manufacturing of the TFP panels.
The RCC substructure has to be designed considering the arch reaction data & load combinations given by Proarch roofing. It shall be within the purview of the clients Consulting Engineer to ensure the structure is designed to cater to the adverse load conditions.
Proarch Roofing Profile, the TFP, is installed over concrete gutter-beams. The conceptual design / drawing of the required RCC gutter-beams are shown in figure (4)
Accessories like ventilators and skylights can be provided with Proarch Engineering Roofing at the crown/ridge only by making cutouts in the Proflex panel. Cut out can be provided at every 20th panel (i.e. 20ft) incase of OFP and 10th panel (i.e. 20 ft) incase of TFP in the longitudinal direction of the building. The size of the ventilator is 24” diameter and its capacity is 2200 CFM. As thumb rule calculations, you can provide one ventilator for every 100 Sq. mtrs area. Skylights are of 2 mm polycarbonate or FRP material. 2’ x 7’ is std., but can be offered in other sizes. Hangers for lighting requirements can also be provided. The maximum load that we can hang from the roof is between 10-15 kg UDL per sq. meter. (uniformly distributed load) The maximum point load that we can hang is between 60-70 kgs but would vary and depend on the location at the roof and its end application. But this needs to be informed before material selection so this criterion can be taken into design consideration. Besides it is equally important to have a layout for hanging points in order to confirm the loading with respect to client’s end application requirements.
