As an effective seismic-resistant construction method, our company proposes a hanging method that involves cutting the three sides of the columns and beams.
At our company, it is natural for seismic slit materials to demonstrate their effectiveness during an earthquake, but we believe it is important that they continue to be effective for a long time without the need for large-scale repairs after the earthquake. Based on the above considerations, we propose the use of complete slit materials.
Scope expansion and update completed! Introducing complete slits with thin residuals using high-precision cutting machines.
The "Thin Residual Type Complete Slit" is a seismic reinforcement method for columns using post-installed slits. The design and construction guidelines are suitable for the design and construction of post-installed slits in secondary walls of existing RC (Reinforced Concrete) and SRC (Steel Reinforced Concrete) structures. These design and construction guidelines can also be applied to renovation work when seismic slits are not installed according to the design documents in existing buildings (including those constructed after the seismic code revision in 1981). 【Applicable Columns and Beams】 ■ The concrete compressive strength of columns and beams should be between 13.5 N/mm² and 36.0 N/mm² when designed for seismic reinforcement. ■ The cross-section size of columns should be at least 400×400 mm. ■ When applying to extremely brittle columns, it is limited to columns with a shear reinforcement ratio (pw) of 0.1% or more. *For more details, please refer to the PDF document or feel free to contact us.

The unique texture that changes its impression over time is not only beautiful but also a design that incorporates functionality, such as reducing unpleasant vibrations.
Adopting the industry's first temperature sensing technology that utilizes natural energy without electricity.
This is a ventilation grille that can be used as a ventilation and air circulation route for basic insulation construction methods.

It is designed with a focus on design and safety, making it barrier-free compliant.
Non-slip. Non-fall. Non-trapping. A refined design with high drainage capability and barrier-free grating.
We would like to introduce the "Neo-Slit" trench covers and bolt-fixed type handled by Okagreat Co., Ltd. (from site-cast gutters to exteriors and various scenarios). We thoroughly pursue improvements in "slipping," "falling," and "getting caught," which are required for grating. Compared to conventional grating, the refined design and the 2% slope from both ends to the center created by the patterned steel plate on the top surface achieve a high balance of "drainage performance" and "anti-slip" effect. 【Features】 ■ Beautiful pearlescent patterned steel plate covering the product surface (anti-slip effect) ■ 2.0% drainage slope towards the central slit on the surface of the steel plate (high drainage performance) ■ Structure that minimizes water accumulation on the top of the cover (design quality) ■ Barrier-free design that does not obstruct pedestrian traffic or wheelchair access ■ Safety (durable surface material structure) ■ Reliability (non-slip due to patterned steel plate) ■ Strength (up to maximum T-14 load) ■ Lightweight (lighter than fine mesh) ■ Aesthetic (prevention of clogging) ■ Damage prevention (force distributed over the surface) *For more details, please refer to the PDF materials or feel free to contact us.

Non-slip. Non-fall. Non-jam. A refined design with high drainage performance and barrier-free grating.
We would like to introduce the "Neo-Slit" type drainage grate handled by Okagreat Co., Ltd. We thoroughly pursue improvements in the issues of "slipping," "falling," and "getting caught" that are required of grates. Compared to conventional grates, the refined design and the 2% slope from both ends to the center created by the patterned steel plate on the top surface achieve a high balance of "drainage performance" and "anti-slip" effect. 【Features】 ■ Beautiful pearlescent patterned steel plate covering the product surface (anti-slip effect) ■ 2.0% drainage slope towards the central slit on the surface of the steel plate (high drainage performance) ■ Structure that minimizes water accumulation on the lid (design quality) ■ Barrier-free design that does not obstruct pedestrian or wheelchair access ■ Safety (durable surface material structure) ■ Reliability (less slippery due to patterned steel plate) ■ Strength (up to maximum T-14 load) ■ Lightweight (lighter than fine mesh) ■ Aesthetic (prevents clogging) ■ Damage prevention (distributes force over the surface) *For more details, please refer to the PDF document or feel free to contact us.

![[NEW] Staircase Slit Case Collection](https://image.www.ipros.com/public/product/image/007/2000347381/IPROS40846425963015316235.png?w=280&h=280)
We have compiled a collection of examples for the design of slits to be installed at the junction between the stairwell and the secondary wall to avoid constraints.
Even if slits are created in the walls of the stairwell, the columns and landings are integrated, so the walls restrain the columns. It is necessary to ensure that the columns are not restrained by either creating slits between the walls and the stairs or constructing the stairs with a steel frame. As stated above, when handling the walls that support the stairs, we must consider creating slits to avoid restraining the columns or constructing the stairs with a steel frame. We will receive detailed CAD drawings of the stairs, and the manufactured products for the stair and landing sections will be delivered to the site. The installation will be to the extent of fitting them on-site, which will also improve the efficiency of the work process.
