茨城県コンクリート製品協同組合 List of Products and Services

The "metal lid (grating) anti-theft fittings" have a very simple structure, making installation easy and allowing for cost-effective measures. We offer two types: "push-in type (integrated)" and "screw type (split)." By attaching the anti-theft fittings, the grating cannot be easily removed due to the weight of the side cover plates, and it also helps prevent it from bouncing up. 【Features】 ■ Extremely simple structure ■ Easy installation ■ Two types available ■ Suitable for anti-theft measures for grating ■ Approximately 200,000 units delivered for public works nationwide *For more details, please refer to the PDF materials or feel free to contact us.

• Paving Materials

The "IGK" is a foundation block for guardrails that eliminates the sliding of products in all directions during vehicle collisions by connecting them with two bolts. Traditionally, the ends of the product's base plate were shaved inward, and the gaps that formed in the base plate were filled with fresh concrete on-site for connection. However, by shaving the ends of the base plate inward, it became possible to accommodate road curves. Additionally, it features a labor-saving advantage by eliminating the need to pour fresh concrete into the gaps at the product connection points. **Features** - Improved safety and workability of guardrail foundation blocks - Fixes sliding in all directions during vehicle collisions - Accommodates road curves by shaving the road side of adjacent parts - Facilitates easier connections between adjacent blocks, reducing construction labor - Selected for the Ibaraki Design Selection 2021 *For more details, please refer to the PDF document or feel free to contact us.*

Compared to conventional drainage covers, the drain cover has a 2% odor distribution on its surface, which excels in water collection functionality during heavy rainfall and similar conditions, ensuring safety and eliminating traffic obstacles. Additionally, the patterned design that considers aesthetics prevents slipping and is also compatible with barrier-free accessibility.
