Korea Expressway Corporation's Innovative Product No. 1 SUNGHYUNTECH

SUNGHYUNTECH Co., Ltd. was founded in 2017 with the vision to achieve eco-friendliness, process improvement, and cost reduction
with convergent technologies to substitute for outdated materials and systems in the construction market.

First temporary material to be designated as an Excellent Product certified by the Public Procurement Service of Korea SUNGHYUNTECH
values the environment and construction sites

SUNGHYUNTECH faced the challenge of introducing a new system to the conservative construction market.
However, the challenge could not make SUNGHYUNTECH stop moving forward. It kept making strong efforts for R&D to address the environmental issues and internal and external difficulties in the construction market.

What captured SUNGHYUNTECH's attention was formwork. The existing formwork incurred lots of waste and had problems such as the lack of durability that would lead to poor structural quality as well as safety risks for construction workers and inefficiency at work.

To create a smart construction environment, SUNGHYUNTECH started developing the H.F.C Eco-friendly Floor Formwork as an alternative to girder bed formwork materials.

The first domestic application of the H.F.C Eco-friendly Floor Formwork was Korea National Railway's leading-in railways for Pohang Yeongil Bay New Port in 2017.

Since then Korea Expressway Corporation, LH Corporation, and many local governments have incorporated or revised existing design to employ the formwork, and many projects are underway. One of the most important advantages of the H.F.C Eco-friendly Floor Formwork is that local governments, public authorities, and other clients can employ this product by incorporating in new design or revising existing design depending on their needs.

Recently the product was designated as a K-Innovative Product by the Public Procurement Service, hence eligible for preferential treatment in ad-libitum contracts with public agencies.

In addition, public agencies and governments are increasingly interested in SUNGHYUNTECH's products to garner additional credits for the purchases of technological development products in public agency and local government evaluations.
