Dong Shin Materials Co., Ltd.

Greeting, 

We are Dong Shin Materials, a world-class company equipped with the best technology and continuing to develop.

Our company started GFRP rebar mass production technology R&D in 2019 and was established in 2022 when it completed overwhelming technology development, and has been guaranteed product quality with unrivaled technology and perfect quality.

All members have been working together to become the best in various fields, from material technology and equipment manufacturing to finished product manufacturing, and thanks to their efforts, Dong Shin Materials has been able to come this far.

Dong Shin Materials will continue to move forward for continuous development without betraying that trust so that customers can trust and entrust it.

Thank you

Damage to concrete structures due to corrosion of reinforcing steel within the concrete

It causes collapse of concrete structures before their expected lifespan and high maintenance costs.

GFRP REBAR

Glass Fiber Reinforced Plastic Rebar

 It is a lightweight material that is 1/4 the weight of existing reinforcing bars and has 3 times stronger tensile strength. It does not rust and corrode, making it the most suitable new material for civil engineering and buildings where maintenance of reinforcing bars is frequent due to water and chloride.

Carbon emission, which is a major issue worldwide, is also 75% lower than that of rebar production

Due to its non-conductive insulation properties, there is no heat transfer, so there is little damage and it is used instead of reinforcing bars to minimize electromagnetic wave interference.

It is widely known as a more expensive material than rebar, but its lightweight and long-lasting advantage lowers incidental and maintenance costs.

With the overwhelming technology of Dong Shin Materials,

you can find it at a more competitive price than rebar.

Technology

R&D

 

We design and manufacture production machines considering the characteristics of our products, and upgrade them frequently.
No one knows the machine better than the one who built it.

Quality

 

Managers with quality standards and process management capabilities built up through decades of experience in collaboration with the world's largest electronics manufacturing companies develop and produce products.

Capacity

 

We have an overwhelming production capacity compared to our competitors in the industry.
Differences in output per hour are, after all, differences in price competitiveness. 

GFRP Applications

Replacing steel rebars

High-rise building foundations, roads, bridge decks, steel tower foundations, railway slabs, precasts, dams, flood prevention facilities, electromagnetic interference prevention facilities, tunnels, breakwaters, runways, etc.
Due to the excellent features of GFRP rebars, it can be used as alternative to almost all the structures where steel rebar is being used.
