Sustainable metal roofing with green steel Roll-on Green Steel reduces CO2. Innovative logistics warehouse being built in Rio with a focus on sustainability.

The use of metallic cover Sustainable sustainability has proven increasingly essential for reducing the carbon footprint in construction. In addition to bringing environmental benefits, such as reducing CO2 emissions, metal roofs also have advantages structural and aesthetic.

O roofing system Roll-on has stood out as an innovative alternative for construction projects, especially in logistics warehouses. A steel roof Roll-on Green Steel, for example, is a sustainable option that significantly contributes to reducing CO2 emissions. The adoption of this type of coverage represents an important step towards the construction of more sustainable buildings that are in line with current environmental standards.

Marko Sistemas Metálicos innovates with Roll-on Green Steel roofing

In this context, Marko Sistemas Metálicos, exclusive manufacturer of the Roll-on roofing system, a product patented in more than 20 countries, is engaged and begins producing the material to begin, in the second half of the year, work on the first logistics warehouse in Brazil with Roll-on Green Steel roof using steel with reduced CO2 emissions, an innovative product that contributes to a greener and more sustainable future. The warehouse, located on Rodovia Presidente Dutra near São João de Meriti, Baixada Fluminense do Rio, will receive the certificate of green steel XCarb™ from ArcelorMittal, the country's largest steel producer and leader in the world market.

Commitment to the environmental agenda and ESG Criteria

The certificate is part of the XCarb® Program and represents the path towards decarbonization of the steel production process and the goal of zero emissions by 2050. According to Marko's Director of Operations, Christophe Schwarzberg, the so-called green steel, with reduced emissions of carbon, should soon be consolidated in Europe and the other countries will follow this agenda, which is already happening in Brazil. For him, within this awareness of sustainability process, customers will want to offset carbon emissions in the construction process of their projects and Marko is ready to serve them.

Innovations in thermal comfort with galvanized steel

'Our roof is already designed to enable energy savings, water reuse, application of solar panels on the roof, various thermal and acoustic comfort solutions, and now, with steel with reduced carbon emissions, it is definitively consolidated as a solution aligned with environmental protection', says Christophe. According to him, the company added this concept to its coverage system in a move to bring increasingly sustainable resources to logistics condominiums, meeting not only customer demand, but also increasingly aligning itself with the ESG agenda.

Innovative technology and sustainability in metal roofing

He highlights that the Roll-on roof, in essence, already has the DNA of sustainability as it is an industrial metal structure, 100% made from galvanized steel without welding, overlapping, without the need for painting or other environmentally aggressive processes. 'We are proud to have an exclusive product in the world, with technology developed by the company and fully aligned with sustainability. Our system provides a clean work, allows water to flow to the end of the building, facilitating the training of rainwater for reuse and eliminating the need to use a drainage network inside; allows natural ventilation and thermo-acoustic insulation, reducing energy consumption; and, also, there is the possibility of recycling leftover steel, as it has high added value and can be melted to make other parts', he details, also highlighting that Marko is currently considering resuming its affiliation with GBC – Green Building Council – organization whose mission is to develop the sustainable construction industry in the country.

Expansion and efficiency in metal roofing

IBGE data reveal that metal structure production in 2021 reached 1,67 million tons. A survey by ABCEM – Brazilian Metal Construction Association, indicates that, since 2019, the sector's growth has reached 21% per year. Christophe complements the numbers, highlighting that Marko has reached the mark of 20 million m² of metal roofing installed in recent years, recording an annual average of over 1 million m² of Roll-on roofing executed. According to him, during the pandemic he saw demand grow significantly. 'This is explained by the overwhelming advancement of e-commerce', he says, announcing that the company is in the process of expanding 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 large logistics developers, such as Prologis, GLP, Brookfield, Gtis, BRProperties, Bresco, Hines, among others, plans to invest, in 2024/2025, R$ 20 million in construction of a new manufacturing unit in Pernambuco, in addition to evaluating the implementation of another factory, this time on American soil. The company's estimate, whose revenue is around R$400 million per year, is to close the year with revenue 30% higher than last year.

Rationalization and sustainability with Roll-on coverage

About Roll-on A genuinely Brazilian system, Roll-on allows a large internal area free of columns for better use of space, with large distances between spans, as the pillars and beams are thinner than their concrete equivalents, or In other words, the internal area increases and the distance between the pillars also increases. With it, there is rationalization of material and labor, as the industrialized system avoids waste and requires fewer workers. It also has renovation flexibility, as it makes it possible to incorporate new metallic elements to meet the needs of new projects. With the advantage of mounting the cover completely on the ground, it brings safety to the service, as it reduces work at height by more than 90%. It is a product with ready delivery and quick assembly, which is why it accelerates the physical-financial schedule of the work and becomes more attractive for large projects that need to comply with a tighter schedule depending on all parts of the project.

Environmental initiatives with XCarb green steel certificate

About XCarb greenhouse gases 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, guaranteed by DNV, an independent body that certifies 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.
