RECTOR: Floors & Horizontal Structures

For over 70 years, RECTOR has been shaping the French construction landscape. Heir to a family industrial tradition rooted in the Grand Est region, the brand today embodies the avant-garde of sustainable construction, thanks to a strategy based on theinnovation, the quality and the environmental performanceWith its 12 factories spread across the country and several European locations, it responds to current construction challenges with solutions concrete prefabrication technical, reliable and low carbon footprint.

A committed family industrial epic

The RECTOR story began in 1953, in Cagnes-sur-Mer, with an innovative patent for a prestressed concrete beam. It was quickly integrated into the Lesage family group, the company is part of an industrial tradition that dates back to the end of the 19th century, in Mulhouse. Initially specializing in tiles and bricks, the Lesage family made the strategic choice of concrete prefabrication, opening a new era for construction.

“The family business spirit is our driving force. It drives us to innovate every day in the service of the sector.”

Over the decades, RECTOR has become a key player in the manufacturing ofsupporting elements et prefabricated structures : beams, pre-slabs, pre-walls, and more recently complete construction systems.

Innovation, the brand's DNA

At RECTOR, innovation isn't just about creating new products. It's a true culture that permeates the entire organization. The company holds numerous patents, including:

• La beam without prop : simplifies installation and speeds up construction sites.

• Le Rectolight flooring : light, practical, low environmental impact.

• La Thermopredalle : integrating thermal bridge breakers.

• Le Thermorefend : thermal corrector for pre-walls.

These innovations are based on a integrated R&D center where materials engineers, thermal engineers, and acousticians collaborate to anticipate the needs of the industry. The result: solutions that combine technical performance, speed of implementation, and energy efficiency.

An offer that meets climate challenges

Aware of the climate emergency, RECTOR is developing low carbon concrete integrated into the Rsoft range. This innovative concrete helps reduce the carbon footprint of a pre-wall 53% and that of a pre-slab of 59%, compared to classic solutions.

The levers of low-carbon concrete Rector

• Clinker reduction : substituted by slag or limestone.

• Recycled aggregates : from demolition, promoting the circular economy.

• Optimized formulations : less cement, less water.

• Local supply : short circuits = less transport = fewer emissions.

“Between 50 and 70% less CO₂, while guaranteeing the sustainability of the structures”

Standards and compliance: rigor at all times

RECTOR's low-carbon concrete does not compromise on regulations. It complies with the most demanding standards:

• NF EN 206/CN : defines the composition and durability of concrete.

• EN 197-5 : authorizes the new CEM II/CM and CEM VI cements.

• FDES conform to the RE2020 : traceability and calculation of the carbon footprint.

• NF EN 15804+A2 et EN 16757 : for life cycle analyses (LCA).

These guarantees provide building professionals with technical reliability optimal, without compromising on the environment.

A strong industrial presence, local and European

With 12 factories distributed throughout France and locations in Belgium, Poland, Slovakia and the Czech Republic, RECTOR maintains a logic of local productionThis promotes:

• La reduction of delays logistics.

• Un controlled environmental impact.

• Territorial anchoring andlocal job.

RECTOR is also committed to theenergy autonomy of its sites, by integrating energy recovery and renewable production systems.

A range designed for all market segments

Featured Products and Systems

• Concrete beams : prestressed or reinforced, historic core business.

• Pre-walls / pre-slabs : prefabrication solutions for floors and walls.

• Equatio / Caméléo Systems : constructive innovations for the home and the community.

• SIP (Prefabricated Infrastructure System) : for sustainable infrastructure.

• Rsoft : solutions to low carbon intensity, certified and efficient.

• Concrete frames and structures : prefabricated load-bearing elements (posts, beams, purlins) allowing for robust, modular and quick-to-implement structures.

RECTOR operates mainly in the residential market (individual houses, collective housing), but its growing expertise in tertiary works opens new horizons for him.

Concrete and anchored CSR commitments

RECTOR's positioning is not limited to product innovation. The company asserts its human values through :

• La creation of skilled jobs.

• The use of local suppliers.

• The implementation ofsocietal actions in the territories.

• Supporting its employees in their upgrade skills.

All this makes RECTOR a deeply responsible, faithful to the heritage of the Lesage group, whose history spans generations.

RECTOR, a pillar of the transformation of the construction industry

In a rapidly changing sector, RECTOR is establishing itself as a reference actor, capable of meeting the new requirements of sustainable construction. Its technical expertise, territorial anchoring, low carbon offer and dynamic of continuous innovation make one strategic ally for professionals looking for long-lasting and efficient solutions.

“Building differently, faster, cleaner, it’s possible. RECTOR proves it every day.”
