SECTION 1.1
Manufacturing Company: Manazil Steel Framing Factory LLC Contracting Company: Gulf Genesis General Contracting LLC Parent Company: Al Fahad Holding Sister Company: Khalifa Al Fahad Contracting
Genesis Worldwide Inc., an industry leader in “green” structural building technologies using light steel in the residential, commercial and institutional construction markets, established in December 2007, the production facility of its licensee, Manazil Steel Framing Factory (“Manazil”) in Abu Dhabi.
Manazil is a subsidiary of Al Fahad Holding of Abu Dhabi, an Emirati construction company established in 1980. The Company previously announced the signing of the License & Services Agreement (the “Agreement”) on July 10, 2007. Under the terms of the Agreement, Manazil is the exclusive provider of Genesis building systems in the United Arab Emirates and Qatar.
The company has a joint venture with Qatarco Trading and Contracting, which oversees all company’s operations in the state of Qatar. In addition to building villas, office spaces, government buildings locally, Manazil has recently started to export steel structures to neighbouring countries such as Iran and Afghanistan to build houses and schools in earthquake affected areas.
The Manazil manufacturing plant, located in the industrial zone of ICAD, produces light steel paneled structures using the Genesis turn-key solution, which includes leading-edge software, industrial equipment, hardware, processes and engineering services (“Genesis Solution”).
Genesis light steel structural technology, an energy efficient, environmentally friendly building alternative, is well suited to the hot climates of the UAE. The Genesis Solution utilizes a cavity wall design that incorporates air barriers, vapour barriers and insulation materials in order for its structures to improve energy efficiency, as opposed to the use of a single material, such as concrete, which does not conserve energy as well as buildings with a cavity wall design. By using light steel, less energy is consumed in order to bring the temperature down to a comfortable level.
Manazil is contracted to build large family style villas, schools, offices, labour camps which can be constructed with speed, cost-effectiveness and efficiency, an improvement on the traditional concrete building methods often used in MENA.

walls are sandwich panels and floors are 200mm pre-cast slabs. Our proposed solution is a cold-formed
steel framing system. Walls are pre-manufactured panels finished with cement boards at each side and
floors and roof to be pre-manufactured panels with concrete topping and cement board at ceiling side.

Advantages of the Proposed Product
SECTION 2.7
SECTION 2.т Advantages of the Proposed Product:
Lightweight - Cold-formed steel components weigh approximately 80% to 90% less than pre-cast concrete, which
means easier handling during construction and transportation.
High-strength and stiffness - As a result of the cold-forming process, cold-formed steel possesses one of the
highest strength-to-weight ratios of any building material. This high strength and stiffness advantage means more
design flexibility, wider spans and better material usage.
Fast and easy erection and installation - Building components made of cold-formed steel can be fabricated with
high accuracy in a plant and then assembled on job sites, which greatly increases erection efficiency and ensures
construction quality.
Dimensionally stable material - Cold-formed steel does not expand or contract with moisture content. In addition,
it does not split or warp as time goes by. Therefore, it is dimensionally stable. Cracked gypsum sheathed walls, nail
head popping and other common problems with wood-framed structures can be virtually eliminated in buildings
with cold-formed steel stud walls.
No formwork needed - The use of cold-formed steel decks eliminates the formwork for pouring concrete floor. In
addition, composite action between the steel deck and concrete increases floor strength and stiffness.
Durable material - Cold-formed steel is durable because it is termite-proof and rot-proof. In addition, galvanized
cold-formed steel products can provide long-term resistance to corrosion.
Economy in transportation and handling - Lightweight cold-formed members or panels are easy to handle and to
transport. In addition, they can be nested and bundled, reducing the required shipping and storage space.
Non-combustible material - Steel is a non-combustible material and will not contribute fuel to the spread of a fire.
This can result in better fire resistance and lower insurance premiums.
Recyclable nature - Steel is North America No. 1 recycled construction material, with a minimum 25% recycled
content. Steel products used in construction are infinitely recyclable, with no degradation in structural
properties. It can be recycled and reused. Steel-framed housing dramatically reduces the amount of trees
consumed for residential construction, thus conserving one of nature's most precious resources.
