Fields of Activity

Recent advancements in the technology and know-how have made it possible to produce formable and flexible materials which were once thought to be unattainable. In recent years, architects have paid a considerable attention on using GFRC and GFRG materials and taking advantage of them in the design and execution of the building facades.

Today, taking advantage of sublime expertise of Iranian engineers and craftsmen, these materials are produced in Pars Nama business unit affiliated with Omran & Maskan Esfahan Co., having some significant qualifications such as excellent formability which correspond to the design, durability, and lightening of the structure.

In order to indigenize the process of design, production, and implementation of GFRC and GFRG parts, an allover investigation was performed among the most creditworthy producers of the product in the world. As a result of these investigations, which resulted in transferring of pertaining knowhow.

At present, Pars Nama business unit affiliated with Omran & Maskan Esfahan Co. operates in various fields such as; design, production and execution of building facades, city furniture, and interior decoration taking advantage of GFRC at international levels.

Technical Unit

One of the most important divisions of this business unit is the Technical Unit, considering the fact that every procedure must be monitored and checked in compliance with by-laws and guidelines in order to produce standard parts, benefiting expert staff, highly updated knowledge and software, the necessary measurements and investigations are taken. To do so, and in the first step the design of the façade which can either be produced by our architecture team or placed by the client goes under inspection. In the next step, the design structural calculations are done and architectural considerations are taken. Then the complete design is divided into small parts and is sent to the production.


Mould and Metal Work

In this stage, the design of the mold and the part supporting frame is sent to molding and blacksmith unit for producing appropriate mold and other fixture and appurtenances. At first, the model of the mould is produced and then according to the type of design and kind of implementation, the material of the mould (wood, silicon, or fiberglass) is chosen and the mould is produced. The metal fixtures and appurtenances are produced in the blacksmith division using a special technique for each product (GRC, GRG, or GRP). At the meantime, the frames and are designated and put on the façade.


Production of Panels

Having produced the moulds, metal frames, fixtures, and appurtenances for the panels, the production of the panels is initiated. Two methods; spray method and premix method, are used in proportion to the type of design and the cast condition. Using quality materials and special techniques in production, improves the density and curing so much that as a result the end product would enjoy a very high quality. The panels, after the production, are packed using standard methods and dispatched to the location of each projects as per their technical codes.


Quality Control

Control of the quality form dimensions, surface finishing, material specifications, is carried out step by step at every stage in order to attain the highest quality levels. After curing and the completion of surface finishing, the products are packed and dispatched to the location of each project according to their technical code.

In the location, the panels are installed on the frames with a very high precision. Fixing the panels onto the frame is performed using bolted or welded connections in accordance with authentic standards. At the end the joints between panels are sealed with special flexible sealing materials.


GRC Introduction

Glass Fiber Reinforced Concrete (GRC/ GFRC) is a kind of composite concrete based material compounding cement, stone granule, water, anti-alkali glass fibers and other additives. Force transfer in this material is through shear stress transfer among the fibers. Every GRC panel is composed of one main coating with the minimum thickness of 18 to 19 mm, which is installed on the metal frame as to fabricate the façade for the structure. Mechanical properties of GRC depends on various elements, such as; blending, production method, type and amount of fabrics, length of fabrics, type of additives. 



Abrasion Resistant Glass Fibers

The amount of abrasion resistant glass fiber in GRC products is between 2 to 5 percent which is added to GRC mortar through spraying or pre blending method during the process of production in the factory. Having the mentioned fabrics in GRC, is a prominent advantage of these products whereas it can fortify both elastic and pressure resistance which is a very important factor in extending the durability and removing common cracks of concrete.


GRC Advantages

  • Variety in dimension and size favorable for designers
  • Rapid installation which can result in speed up of the project
  • Resistant to any climate esp. in wet regions
  • Resistant against earthquake and fire
  • Anti-dust quality


Environmentally friendly

Employing GRC panels, results in reducing the amount of concrete and metal in structural steelwork and therefore lightening of the structure. It is noticeable that natural materials like wood, earth, etc. are not used in producing these panels. This product does not emit fumes or harmful waves in the location and does not threat the residents' health as a result. Some other benefits of these products in line with preservation of nature are as following:

  • Reducing the excavation of natural resources
  • Using recyclable and renewable materials
  • Reduction in fuel used for their transportation in comparison with heavier materials
  • Appropriate insulation
  • Lightening of the structure


Latticed Panels as a Potential for Special Light Design

One technique in segmenting the space without creating noise in environmental light, is to use latticed panels in in designs. GRC panels can be produced in latticed panels in favorable forms and dimensions without any need to cutting and waste of material.



Anti-dust quality by Applying Nanotechnology

GRC panels' technical specifications suggest very low absorptive capacity to water, moreover; they can become fully water-proof by spraying a hydrophobic nano-coating layer, which is transparent and has no effect on the color, onto them. This process results in zero water absorption in such panels. This is an outstanding advantage in maintaining cleanliness of the panels at the time of acid rains. By applying nano-coating onto the panels, dust cannot penetrate into their material and they become furnished just by a dash of water or rain.


Earthquake and wind Proof

In order to scrutinize the impacts of earthquake and wind in designing the facades, panels and installation frames are analyzed by applying expert software and according to the latest by-laws in building construction.  


Lightness of Panels

Although the specific weight of the concrete used in the panels is almost the same as the concrete used in common concrete, the production of thin panels is also possible thanks to its high bending potential. Thus, surface unit weight of such material is less than other common materials in making façades. This business unit., taking advantage of optimum design and accurate installation system, brings about the lightest possible output in the project. 


No Limits in Design

No limit can be imposed on design by employing GRC. Applying these products can make architects' most high-flying images practical. By using these materials, very unique and outstanding façade making projects can be carried out.
