We have been awarded the "Good Design Award" for the 2024 fiscal year. Featured in the 2024 new catalog is the "New Model SUS Grating 'Fine Grate'." Achieving high strength and high durability with a new manufacturing method!
The new model "Fine Grate" of stainless steel grating, featured in the 2024 catalog, has won the 2024 "Good Design Award." It demonstrates high durability performance against loads in the "twisting" direction! The OG Super High Tensile High Strength Stainless Steel Grating. Achieved through a manufacturing method different from conventional ones. We would like to introduce the new model "OG Super High Tensile High Strength Stainless Steel Grating" (U-shaped gutter type). The material used is NSSC low-alloy type duplex stainless steel, which boasts about twice the strength of SUS304 stainless steel. The manufacturing method of the OG Super High Tensile High Strength Stainless Steel Grating has been improved! It exhibits high durability performance against loads in the "twisting" direction! The new model combines the uneven parts of two components for bonding. This structurally enhances strength and achieves even higher load-bearing performance. It also exhibits high durability performance against "twisting" loads caused by "vehicle tires," which conventional products struggled with. The "R" shape of the flange allows rainwater to be quickly directed into the side gutter, enhancing drainage performance. Please feel free to consult us when placing an order. *For more details, please refer to the PDF document or feel free to contact us.*
