Sustainable Metal Roofing with Roll-on Green Steel Reduces CO2. Innovative Logistics Warehouse Being Built in Rio with Focus on Sustainability.
The use of sustainable metal roofing has become increasingly essential for reducing the carbon footprint in the construction industry. Besides providing environmental benefits, such as reducing CO2 emissions, metal roofs also offer structural and aesthetic advantages.
The Roll-on roofing system has emerged as an innovative alternative for construction projects, especially in logistics warehouses. The Roll-on Green Steel roofing, for instance, is a sustainable option that significantly contributes to reducing CO2 emissions. The adoption of this type of roofing represents an important step towards building more sustainable structures aligned with current environmental standards.
Marko Metálicos Systems Innovates with Roll-on Green Steel Roofing
In this context, Marko Metálicos Systems, the exclusive manufacturer of the Roll-on roofing system, which is patented in over 20 countries, is engaged and starting to produce the material to commence, in the second half, the construction of Brazil’s first logistics warehouse with Roll-on Green Steel roofing using steel with reduced CO2 emissions, an innovative product that contributes to a greener and more sustainable future. The warehouse, located on the President Dutra Highway at the height of São João de Meriti, Baixada Fluminense of Rio, will receive the XCarb™ green steel certificate from ArcelorMittal, the largest steel producer in the country and a leader in the global market.

Commitment to the Environmental Agenda and ESG Criteria
The certificate is part of the XCarb® Program and represents the path towards decarbonizing the steel production process with a goal of zero emissions by 2050. According to Marko’s Operations Director, Christophe Schwarzberg, the so-called green steel, with reduced carbon emissions, is expected to consolidate soon in Europe, and other countries will follow this agenda, which is already happening in Brazil. For him, within this awareness about sustainability, clients will seek to offset carbon emissions in the construction processes of their ventures, and Marko is ready to meet their needs.
Innovations in Thermal Comfort with Galvanized Steel
‘Our roofing is already designed to enable energy savings, rainwater reuse, installation of solar panels on the roof, various thermal and acoustic comfort solutions, and now, with steel with reduced carbon emissions, it is definitively established as a solution aligned with environmental protection’, says Christophe. According to him, the company has integrated this concept into its roofing system as part of a movement to bring increasingly sustainable resources to logistics condominiums, meeting not only customer demand but also aligning with the ESG agenda.
Innovative Technology and Sustainability in Metal Roofing
He emphasizes that the Roll-on roofing, in its essence, already has the DNA of sustainability as it is a metal structure, 100% made of galvanized steel without welds, overlaps, or the need for painting or other environmentally harmful processes. ‘We pride ourselves on having an exclusive product worldwide, with technology developed by the company and fully aligned with sustainability. Our system provides a clean construction site, allows water drainage to the edge of the building, facilitating rainwater collection for reuse and eliminating the need for an internal drainage network; it enables natural ventilation and thermal-acoustic insulation, reducing energy consumption; and it also allows for recycling of steel scraps since it has high added value and can be melted down for the production of other parts’, he details, highlighting that Marko is currently considering resuming its membership in the GBC – Green Building Council – organization that aims to develop the sustainable construction industry in the country.
Expansion and Efficiency in Metal Roofing
Data from IBGE reveals that metal structure production in 2021 reached 1.67 million tons. Research from ABCEM – Brazilian Association of Metallic Construction indicates that, since 2019, the sector’s growth has reached 21% per year. Christophe adds to the numbers, stating that Marko has reached the milestone of 20 million m² of installed metal roofing in recent years, recording an annual average of over 1 million m² of Roll-on roofing executed. According to him, during the pandemic, they saw demand grow significantly. ‘This can be explained by the overwhelming advance of e-commerce’, he notes, announcing that the company is in full expansion not only in the national territory but also advancing throughout Latin America and the USA.
Investments and Projections
Marko, which has among its clients large retail chains, industries, and major logistics developers such as Prologis, GLP, Brookfield, Gtis, BRProperties, Bresco, Hines, among others, plans to invest R$ 20 million in 2024/2025 in building a new manufacturing unit in Pernambuco, in addition to evaluating the implementation of another factory, this time on American soil. The company estimates that its revenue, which is around R$ 400 million per year, will close the year with a 30% increase compared to last year.
Rationalization and Sustainability with Roll-on Roofing
About the Roll-on A genuinely Brazilian system, Roll-on offers a large internal area free of columns for better space utilization, with large spans, as the columns and beams are thinner than their concrete counterparts, meaning that the internal area increases and the distance between columns is also greater. It rationalizes material and labor since the industrialized system avoids waste and requires fewer workers. It also allows for flexible renovations, as it can incorporate new metal elements to meet the needs of new projects. With the advantage of complete roof assembly on the ground, it enhances safety for the service, as it reduces more than 90% of the work at height. It is a product with ready availability and quick assembly, thus accelerating the physical-financial schedule of the construction and making it more attractive for large-scale developments that need to comply with a tighter timeline due to all parts of the project.
Environmental Initiatives with XCarb Green Steel Certificate
About XCarb The XCarb© is a global program from ArcelorMittal launched in 2021, aiming to consolidate all the group’s efforts and investments with the mission to reduce and neutralize greenhouse gas emissions in the steel chain. One of the program’s initiatives is the green steel certificate. These certificates are issued by ArcelorMittal based on CO2 savings, verified by DNV, an independent body that attests to the reliability of the process. When purchasing a product with this certificate, the carbon savings achieved by ArcelorMittal in the process are also transferred to the purchasing company.
