Kham, khamot and khork composite according to listofer provided by the customer are produced in the factory before baking and sent to the project site. Kham, Khamut and composite vaults are produced in all sizes and dimensions.
As you know, composite rebars are produced in longitudinal shape due to the use of glass fibers and epoxy resin, which is a thermoset resin.
Unlike steel rebars, which can be bent in place, because composite rebars are made of glass fibers and epoxy resin, and epoxy resin is thermoset.
After curing, it is no longer possible to bend composite rebars, and in case of bending or applying too much pressure, it will bend to some extent, but after removing the pressure and bending, the rebar will return to its length due to its elastic state and springing again.
from 3 mm to 30 mm in diameter and from 20 cm to 60 cm or more in sizes.
Properties:
- • Anti-corrosion
- • More tensile strength than steel
- • Faster operation and easier cutting
- • Anti-electromagnetic
- • 8 times lighter than steel
- • Non-conductive against electricity and heat
The security and useful life of buildings will not be able to be accurately predicted due to environmental problems in humid and coastal areas.One of its factors is the corrosion of steel bars.
Corrosion of steel bars causes cracking and flaking of concrete, which will reduce performance and significantly increase reconstruction costs.
On the other hand, with the increase of environmental pollution and carbon dioxide and chloride ions, the protective properties of concrete decrease.
The appropriate solution to manage corrosion and reduce the slippage of steel rebar in concrete –both of which cause the concrete to break and honeycomb and as a result the destruction of the structure– is to use composite rebars.
In many projects that are in wet and corrosive areas, the most important factors include increasing the life of the structure, reducing maintenance and reconstruction costs, further retrofitting, and removing corrosive factors.

One of the best and most cost-effective solutions is to replace longitudinal steel bars and steel bends and silencers with composite bars and bends and silencers. It solved the corrosive areas.
It should be mentioned that composite rebars, which are completely non-conductive and anti-electromagnetic, can be used in projects such as hospital MRI rooms or foundations under electric arc furnaces of steel manufacturing companies or in general any project that requires non-conductivity of the surrounding environment.
Application of Composite Bends and Stirrups:
- – Sewage facilities such as treatment plants, clarifiers, manholes, grease traps
- – Channels and concrete pipes for directing sewage and industrial effluents and chemicals
- – Concrete structures of docks and marine structures
- – Structures adjacent to MRI machines in healthcare centers
- – Reinforcement on the deck (deck bridges in cold areas and reinforced concrete infrastructures)
- – Struts in soil and water
- – New Jersey precast concrete road blocks
- – Precast concrete buildings
- – Columns and prefabricated foundation for walling and landscaping
- – Concrete dams
- Breakwaters and marine platforms
- – Prefabricated concrete parts
- – Foundation
- – Pools and concrete tanks
- – Strengthening the coastlines
- – Retaining walls
Using longitudinal composite rebars, composite rebar bridges, bends and stirrups simultaneously and completely in the electric arc furnace foundation project of Shadegan Steel Company, Khuzestan Province
