A MIXED, EFFICIENT, AND ELEGANT CONCEPT FOR MULTI-FAMILY HOUSING
In order to satisfy new national and regional demands for affordable housing projects that can be quickly built up, the Universe Steel Factory Group has developed a productline with its own brand called “Steel Style.” This brand is the result of over a decade of work development close to international architects and engineering firms, aiming to provide a solution for multi-family housing that combines elegance, security and cost efficiency.
This conception is based obviously on using mixed materials to create a thermally and acoustically efficient whole building.
Structurally, the buildings are made of steel, while the envelop consists on prefabricated walls and lightweight coated steel floors.
The industrialized approach, whether it involves wood, metal, or concrete, enables cost-effective and fast construction.
With their innovative design, these multi-family housing units offer flexible layout in order to accommodate to various uses.
Our management system complies with international standards for quality, hygiene, safety, and the protection of environment.
Based on our internal and experienced engineering offices, we are able to anticipate on worksite interventions.
Our welding and assembly teams are trained and fully qualified.
MBG Construction and SIGA have achieved numerous projects and have enough skilled human resources to manage large-scale projects exceeding 2,500 tons of steel transformation workload per project.
Bridges, footbridges, and viaducts are examples of structures that can be built using Steel.
These metal structures offer numerous advantages in terms of strength, durability, and design flexibility. With our expertise in the field of metal construction, we are able to design and to manufacture customized bridges, footbridges, and viaducts that meet the specific requirements of each project. Whether it is for road, railway, or pedestrian projects, we are using advanced technical solutions to ensure the safety users, functionality, and aesthetic appeal of these longlife architectural structures.
Our experience in building metal bridges, footbridges, and viaducts has enabled us to work on prestigious projects, contributing to the development of transportation infrastructure and the improvement of mobility.
MBG construction and SIGA companies are specialized in the construction of airport’s hangars, railway stations, bus warehouses and airplane’s maintenance tunnels.
We are aware of the capital importance of these transport hubs for the monitoring safe use of travelers and freight in addition to the preservation of big and expensive associated means of transport.
Thus, we are committed to provide innovative and high quality solutions to fullfil the specifications of every logistic project.
TAILOR-MADE LIVING SPACES
Office buildings and commercial structures have undergone significant changes in recent years. Architectural boldness, lightweight structures, useness, environmental impact, energy consumption optimization and building performance are becoming new lifeway challenges worldwide.
The Universe Steel Factory’s metal construction division, with their rich experience has developed a real expertise in building tertiary buildings.
Steel construction of such structures provides modularity, fast assembly, and an actually cost efficiency for investors.
Our Metal Constructions companies are able to customize mixed building cladding (concrete-metal, architecturally designed metal facades, etc.) for the all building project.
A HYBRID CONSTRUCTION METHOD FOR CONTROLLED COSTS AND DELIVERY DEADLINES
New technical design of tertiary buildings meets the needs of our customers and contractors as we commit to produce at controlled costs and delivery deadlines by using various solutions such as:
The closed-roof solution concept
Prefabrication of the structure in workshops is made by standardized elements to allow fast assembly and guarantee clean worksites with minimal disturbance.In addition, modularity and adaptability are main characteriscts of rationalized design through multiple set up combinations.
Therefore, office buildings and real estate structures can been built up to last international standards.
The construction processus developed by the metal construction companies within the Universe Steel Factory conglomerate are fully checked and managed in our factories, by our facilities and employess who are monitoring the transformation of a big range of raw materials to be sure that “the right part is used in the right place.”
The metal companies of Universe Steel Factory Group provides their expertise and rich knowledge to carry out complex projects and fullfil whole specifications using international profed refrences .
Our management system complies with international standards for quality, hygiene, safety, and the environment. With our integrated and experienced engineering offices, we are able to anticipate on worksite interventions. Our welding and assembly teams are trained and skill qualified. MBG Construction and SIGA compnaies have completed numerous projects and have enough capacities of managing large-scale projects exceeding 2,500 tons of steel transformation workload per project even in high demanding fields like electronic phamaceutical and chemical industry.
Société historique du conglomérat Universe Steel Factory et appartenant à l’actionnaire principal Poulina Group Holding, MBG Construction joue un rôle capital dans la fourniture de bâtiments légers de haute qualité. Notre propre marque « SteelStyle », gamme de produits de pointe, incarne une approche écologique, abordable et conforme aux normes strictes.
De l’évaluation des besoins à l’assemblage final des structures, chaque étape du projet est régulièrement contrôlée par notre personnel interne de contrôle qualité.

Notre équipe assure ensuite un montage rapide sur site.
De plus, les constructions de logements collectifs SteelStyle répondent à des objectifs de haute qualité environnementale (HQE) afin d’atteindre l’objectif de moindre empreinte carbone.
STEEL CONSTRUCTION: THE BEST ANSWER TO RETAIL & MALL REQUIREMENTS
Commercial malls require large spaces for circulation, storage, functional layouts, and public’s crowd security. The steel structure and construction methods of MBG Construction and SIGA companies provide adapted solutions to these requirements by:
– Minimizing the number of columns in retail areas,
– Managing the sometimes complex interface between the structure and architecturally designed facades through comprehensive solutions for both structure and cladding.
– Securing compliance with fire stability regulations,
– Reducing timelines and overall costs through technical variations of concrete works with steel components.
A STRONG EXPERTISE AND PROOFED MARKET REFERENCE
Regardless of the project size, our teams are trained to support you throughout your project. Our extensive experience in roofing, cladding, and architectural facades allows us to offer optimized technical and efficient solutions to our customers.
Our references in this activity field include famous local brands like AZUR CITY MALL, Tunis CITY MALL, CARREFOUR MALL, SHOW ROOM LAND ROVER JAGUAR, and MG RETAIL MALL.
