U-profile elements, which will join the foundation with the wall panels, are fixed on the foundation. First two panels are assembled in the corner.

Phase 2: Preparation of the ground - implementation

Mounting of pre-fabricated wall and partition elements is sequenced to build rigid subsets and so ensure stability during construction, especially in case of strong winds.

Phase 3: Walls and partitions assembly

Wall construction is finalised by the connection of the two last panels at the opposite corner.

Phase 4: Two last wall panels

U-profile elements to join walls and roof panels are fixed tothe top of all the wall panels.

Phase 5: Wall and roof joined by a U profile

Assembly of the roofing panels including finishing (mono and duo-pitch ridge, edge,...)

Phase 6: Finishing accessories

A steel deck can be provided for each type of house (12, 20, 30, 40, 55, 71 and 100m²).It is delivered ready to be assembled, with all faste-nings and connection parts, including connections between the structure and the concrete pads.

Depending on the house type, the number of concrete pads will vary.

This solution allows a good evenness of the floor, even on a uneven soil, and is a must in terms of protection in case of torrential rains.

A kit comprising doors and windows can be provided. Exterior doors are insulated, and windows feature double glazing. All doors and windows are made of PVC, except for the exterior doors frames, which are made of aluminium.

For protection, all windows can be equipped with anti intrusion bars.

Technical agreement:ArcelorMittal complies with local construction regula-tions in countries where PROTEA is erected.

Fire performance:The CSIR* in South Africa performed a fire resistance test on the 60mm wall panel, with a 15mm Firestop plasterboard on the exposed side. The complex achie-ved a Fire Resistance Rating (FRR) of 30 minutes.*Council for Scientific and Industrial Research

Structural performance:The PROTEA structural performance has been as-sessed. The house structure is essentially ensured by self bearing panels.

Wind forces:The calculation shows that the PROTEA house is able to resist to winds up to 36m/s (130km/h) with peaks up to 50m/s (180km/h).

Seismic forces:Moreover, steel is known to behave well in an earth-quake. Global failures and huge numbers of casual-ties are mostly associated with structures made from other materials.

This is mainly due to three major qualities of steel: - Light weight:Steel structures are generally lighter than those using other materials. Some steel structures are sufficiently light so that seismic design is not critical. - Flexibility:Steel structures are generally more flexible than other types of structure. Constraints in the structure and its foundations are therefore lower. - Ductility:Unlike other materials, steel’s failure mode is ductile; this means that when submitted to strong forces, steel doesn’t break but dissipates energy by plastic deformation.

Thermal performance calculation:The PROTEA thermal performance has been assessed by thermal calculation.

As a result, this calculation shows that the PROTEA house provides better summer comfort compared to a traditional brick and mortar house (up to 5°C cooler).

Thermal performance measurement:A thermography measurement was performed on a prototype, showing good thermal insulation and air tightness.

PROTEA | Made of safe, sustainable steelThe advantages of steel are numerous and make it an ideal building material.

Steel, a material coming from nature:Iron ore, its raw material, is one of earth’s most abundant elements.

Steel is clean; its manufacturing process as well:Steelworks have cut steel manufacturing’s energy consumption and CO

2 emissions by half compared with 1960 levels.

Steel reduces building site noise pollution and makes for clean and safe construction:Prefabricated materials are delivered, minimising waste and on-site storage and making building sites safe, dry and dust-free.

Steel is sustainable, durable and solid:Today, steel can be effectively protected against corrosion, par-ticularly through the galvanisation process.

Steel is recyclable and recycledSteel is indefinitely and 100% recyclable. More than 40% of the world steel production comes from recycled steel.

Steel is earthquake-resistant:Steel increases building longevity in earthquake-prone areas and preserves human life through its resistance.

Cooperation between «Habitat for Humanity» Haïti and ArcelorMittal

Construction Dominicana (steel roof sheets)

Sandwich panels recycling process:Different studies show that technical solutions to recover steel in buildings and to transform it in high quality scrap exist.

Rotaryshear

Sandwichpanels

Magneticdrum

Scrapmetal

PUR foamflakes

The goal is to separate steel from polyurethane foam in such a way that each component will be pure enough to be easily re-cycled in its own process. Two different tools exist: a shredder commonly used to process end of life vehicles or household ap-pliances, and a rotary shear commonly used to shred steel pack-aging.However, reusing the sandwich panels at the end of the house life could be a much simpler and cheaper solution of recycling.
