Building & Constructions

Cartonplast offers smart and efficient  solutions for building and construction industries

Polypropylene extruded sheets are perfect to be converted into reusable and lightweight products for the construction industry. Working several years with building professionals, we developed solutions to satisfy international requirements of this industry.

All construction projects, no matter whether commercial or not, require firm deadlines, and, managing multiple contractors, are subject to frequent  traffic on-site.

That’s why our temporary floor protections can help you to avoid delays due to accidental damage of surfaces.

We developed an additional tool to speed up your construction work:  permanent formworks. They are durable and robust polypropylene material, u-shaped formworks  can be left on-site and they are delivered to you flat, to save shipping costs.

Our products can be certified flame retardant and are sustainable: polypropylene is a 100% recyclable plastic. Moreover, our products can be made using recycled polypropylene as well.



Today regarding to achieve a safer structure in the less possible time in building industry, using the newly born materials is inevitable. Carton plast company specialists after receiving good feedbacks from the plast sheets which have been used in ceilings and also after the replacement of these products instead of polystyrene blocks decided to inspire the possibility of replacing plastic sheets instead of steel frames, knowing the problems of using heavy steel frames in construction projects.

In the specialists point of view the privileges of plastic sheets in the structures are the lightness, facilitating the execution, impermeability to water (no water absorption of concrete) and resistance to acids and alkaline as while as being economic, in a way that after minimum 6 round framing with plastic sheets these consumed plastic sheets are being used as moisture and heat insulator and also sound proof materials in the roofs and walls.

Generally the applications of plastic sheets in building industry include:


Calvert implementation or expansion joint

Insulation (sound, heat, moisture)


Plastic blocks

Fencing and building panels



Carton plast can also be used instead of concrete in the foundation.

Integrated framing

Plastic framing

The most important privileges of plastic framing in building industry are:

Carton plast never sticks to the concrete

Carton plast is resistant to water, acids, and alkaline.

Carton plast doesn’t absorb the humidity in concrete and so increase the concrete’s strength

Decrease the framing procedure time

Facilitate the frame removing

No waste in the frame removing

Carton plast is reusable

The possibility of parallel execution of beams and columns along with material saving.


The possibility of executing lighter structures which are persistent against the earthquake.

Saving in concrete consumption.

Decrease the labour force needed due to the light frameworks.

Making the execution of special and curvy concrete structures possible.

Provide a smooth and polished surface

High flexibility and possible to be cut in different shapes by a cutter

Environment friendly due to replacing wood by plastic sheets


The sport saloon project in Bam which has been realized by Armeh dasht Company is the biggest project which its framework has been done by plastic sheets.


Curved framework

Column framework

The administration department of NIKPARS company

Construction of a swimming pool on the tenth floor of a building named “Baghe jannat”

Sheikh fazlollah bridge project constructed by SANG O SOTOON Company


The privileges of plastic blocks

Carton plast blocks helps saving the cost of warehouse and transportation as while as provide the possibility of being produced in the flat form and being assembled in the operation.

Carton plast blocks can be produced in different sizes up to the length of 210 cm.

Light weight of the blocks cause about 20% decrease in the dead load of the structure. ( a block with the dimension of 210×60×40 (cubic centimeters) weighs 3.5 kg)

Carton plast can produce specific blocks which are possible to be reused in the ceiling after removal.

Prevent the concrete from the corrosion which can be caused by the polystyrene chips.
