"Fine Grip" is a product that features protruding holes on the surface of steel plates, providing a powerful anti-slip effect through specialized processing. Since the pitch of the holes can be set arbitrarily, it is possible to arrange them to avoid interference with lower structures and to process them along with accessories such as handles. By protruding the hole sections, it demonstrates a strong anti-slip effect, allowing for safe passage. 【Features】 ■ By providing protruding holes on the surfaces of various types of steel plates, the inherent anti-slip effect can be enhanced. ■ Can be used as building materials in environments where safety is required. ■ Not only protruding holes but also patterns that consider drainage, combining with standard round holes or elongated holes, can be manufactured. *For more details, please refer to the PDF document or feel free to contact us.

"Water Through" is a grating product that not only improves drainage capacity but also combines ease of maintenance and enhanced safety during use. By incorporating a slider plate into the receiving frame, the frame, lid, and road surface become almost flat, eliminating tripping hazards for pedestrians and impacts on vehicles. Additionally, the structure is designed to prevent the lid from coming off even during backflow caused by heavy rain, ensuring safety. 【Features】 ■ Stabilizes the flow of rainwater ■ Can handle a large volume of water flowing through the grating into the drainage channel ■ Prevents the lid from floating up ■ Any gaps that may occur after installation are covered by the comb part of the receiving frame ■ Promotes smooth drainage *For more details, please refer to the PDF document or feel free to contact us.

"Electropolishing of Stainless Steel Products" is a technique that involves immersing stainless steel products in an electrolytic solution and applying direct current voltage to induce electrolysis at the interface between the solution and the metal. This process utilizes the metal dissolution reaction at the anode caused by the electrochemical reaction to polish the metal surface. Unlike mechanical methods such as hairline finishing or buff polishing, this technique preferentially dissolves the protruding areas where electricity concentrates, resulting in a smooth surface by addressing the microscopic irregularities of the material surface. 【Features】 - Improvement and modification of stainless steel surfaces - Enhanced cleanability - Adjustability of gloss level *For more details, please request documentation or view the PDF data available for download.
