Leave the manufacturing and sales of concrete secondary products and civil engineering materials to us.
Nikkon Co., Ltd. will provide optimal proposals for construction site projects by comparing and examining various products and methods from different angles in the design work of civil engineering projects. Concrete structures built during the period of rapid economic growth are nearing 50 years old and are deteriorating, with repairs becoming a nationwide issue. This problem is not limited to large structures like tunnels and bridges; even the drainage ditches found in our neighborhoods are not exceptions. At Nikkon, we manufacture and sell concrete secondary products, including the "CR Slab Type II," which remakes only the upper part of deteriorated cast-in-place drainage ditches while leaving the lower part intact, and the "Easy Grating Type II," which removes the upper part of existing cast-in-place drainage ditches, sets a frame with adjustable bolts, adjusts the height, and completes the installation by pouring ready-mixed concrete around it. 【Products Offered】 - CR Slab Type II - CR Slab for Cross Sections - Easy Grating Type I - Easy Grating Type II, etc. For more details, please contact us or download the catalog.

basic information
【Features】 [CR Slab Type II] ○ Height adjustment bolts (patented) allow for easy fine height adjustments of the product. ○ Excellent workability. ○ The approximately 2cm gap between the cut surface of the existing drainage and the product allows for quick release by injecting non-shrink mortar. ○ Each product (2m) can accommodate three covers, making maintenance easy. [CR Slab for Crossings] ○ The receiving frame uses "high corrosion-resistant hot-dip galvanized steel plate" ZAM. [Easy Grating Type I] ○ In cases where early release is required, non-shrink mortar is used to restore asphalt pavement. [Easy Grating Type II] ○ The length of the receiving frame is a four-sided frame of L2015, allowing for two L995 main bodies to be installed. ○ Height adjustment sections are provided at four points of the four-sided frame, allowing for fine height adjustments after installation using adjustment bolts. ○ Adjacent receiving frames can be connected and integrated with bolts. ○ The material of the receiving frame is high corrosion-resistant hot-dip galvanized steel plate (ZAM) → resistant to rust and highly durable. ○ The grating body is fixed with bolts → eliminates the need for complex formwork, leading to a reduction in construction time. ● For more details, please contact us or download the catalog.

Company information
Nikkon Co., Ltd. conducts a comprehensive comparison and examination from various angles when selecting products and methods for civil engineering design work, providing optimal proposals for the site. Structures made of concrete that were built during the period of rapid economic growth are now nearly 50 years old and have begun to deteriorate, leading to repair issues nationwide. This problem is not limited to large structures like tunnels and bridges; even the drainage ditches found in our everyday urban environments are not exceptions. Nikkon manufactures and sells concrete secondary products, including the "CR Slab Type II," which remakes only the upper part of deteriorated cast-in-place drainage ditches while leaving the lower part intact, and the "Easy Grating Type II," a product for repairing transverse drainage ditches that involves removing the upper part of existing cast-in-place drainage ditches, setting a frame with adjustable bolts for the grating, adjusting the height, and pouring ready-mixed concrete around it to complete the work.
