The "OK Type Fireproof Fence (Fireproof Wall) and OK Type Permanent Fence" are concrete fences (walls) that excel in seismic resistance, durability, sound insulation, and workability. Because the wall and the entire structure are integrated, they exhibit remarkable strength against accidents and earthquakes. Additionally, by utilizing the inserts at the bottom of the main body, the floor concrete and the main body can be further integrated. They can be widely used as alternatives to block fences, permanent fences, assembled fences, and cast-in-place concrete fences, as fireproof fences (fireproof walls) or soundproof walls. 【Features】 ■ Strong integrated structure ■ Excellent workability ■ Sound insulation *For more details, please refer to the PDF materials or feel free to contact us.

The "HD Wall" is a retaining wall designed to withstand major earthquakes (horizontal seismic intensity kh=0.25). If within the certification conditions, calculations and other procedures are unnecessary, simplifying the process from planning to approval. As a foundation supporting long-term excellent housing with outstanding technologies such as seismic resistance, vibration control, and base isolation, this product boasts a durability of 100 years. 【Features】 ■ Reliable product certified by the Minister, with simplified procedures ■ Maximizes the use of valuable land ■ Durability is guaranteed (Based on the results of concrete neutralization experiments conducted by the Building Research Institute) *For more details, please refer to the PDF materials or feel free to contact us.

The "OK Guard Wall" is a combined retaining wall and guardrail designed for road use, featuring a vertical front that makes it easy to set up and simple to construct. The standard product can accommodate horizontal alignments with a minimum radius of approximately R=20m, in accordance with the "Guidelines for Road Earthworks and Retaining Walls" and the "Standards and Explanations for Guardrail Installation." Additionally, we offer the "OK Guard Base," which can accommodate an inner curve radius of 8m and a road longitudinal slope of up to 9%. 【Features of OK Guard Wall】 ■ The vertical front makes it easy to set up and simple to construct. ■ The standard product can accommodate horizontal alignments with a minimum radius of approximately R=20m. ■ Full-scale structural experiments have been conducted to confirm the safety of the wall's strength against impact loads. ■ Complies with the "Guidelines for Road Earthworks and Retaining Walls" and the "Standards and Explanations for Guardrail Installation." *For more details, please refer to the PDF document or feel free to contact us.

The "OK Ecoblock" is a large block retaining wall that excels in construction. It is a product developed to meet the demands for labor-saving in construction and reduction of construction costs. By pouring core concrete, it is possible to build a solid masonry retaining wall. With a size of 1m², it allows for labor-saving in construction, and since the block itself is lightweight, it offers excellent economic efficiency. 【Features】 ■ Large size of 1m² for labor-saving in construction ■ Lightweight block body for excellent economic efficiency ■ Self-supporting with horizontal stacking, providing excellent workability (5% slope) ■ Can accommodate 3% and 4% slopes by using dedicated foundation blocks ■ Pattern compliant with the National Research and Development Agency, Public Works Research Institute, Natural Coexistence Research Center Brightness: 4.5, Texture: 14 *For more details, please refer to the PDF document or feel free to contact us.

The "flat block" is a product that can be used for both wall blocks and stacking blocks. It allows for flexible combinations and can adapt to applied structures (such as gravity retaining walls) with ease, while also being easy to install. Additionally, it has high safety due to being connected with rebar. Please feel free to consult us when you need assistance. 【Features】 ■ Balances flexibility and safety ■ Brightness certification obtained *For more details, please refer to the PDF materials or feel free to contact us.
