"Super Crackless" is a three-dimensional wave-shaped steel fiber that can easily produce SFRC (Steel Fiber Reinforced Concrete) by simply adding it on-site to concrete. This document is a collection of examples of civil engineering projects that used "Super Crackless." It includes numerous examples such as the Hokuriku Shinkansen Kaga Tunnel (South) and three other construction sites, the Hokuriku Shinkansen Kuratani River Bridge construction (steel fiber reinforcement), and the Hokuriku Shinkansen Daiichi Nagaya Bridge construction (steel fiber reinforcement). We have introduced these examples using photographs, so please take a moment to read through it.

"Super Crackless" is a three-dimensional wave-shaped steel fiber that can easily produce steel fiber reinforced concrete (SFRC) by simply adding it to concrete on-site. It achieves flexible workability that can accommodate not only large-scale construction but also small-scale projects such as factory floors, store interiors, and residential slabs. For a wide variety of concrete structures that require long-term durability and safety, it demonstrates excellent effects in suppressing cracks due to drying shrinkage and preventing spalling of concrete masses. 【Features】 ■ Suppression of cracks due to drying shrinkage (improved durability) ■ Elimination of crack suppression reinforcement (shortened construction period and reduced costs) ■ Prevention of spalling of concrete masses (improved safety) ■ Significantly improved dispersibility with "three-dimensional wave shape" ■ Outstanding workability with no fiber balls generated *For more details, please refer to the PDF document or feel free to contact us.

The "Super LL Nail" is a product that has undergone screw threading processing on the nail shank to enhance its pull-out resistance. By doubling the nail head area, it prevents the nail head from sinking into the material during installation, securely fastening plywood. This product has obtained evaluation certification from the Ministry of Land, Infrastructure, Transport and Tourism, allowing the use of stainless steel nails in wooden shear walls. These effects contribute to the longevity of wooden houses. 【Features】 ■ Achieves earthquake-resistant walls ■ Certified by the Ministry of Land, Infrastructure, Transport and Tourism ■ Doubles the nail head area to prevent sinking into plywood during installation ■ Increased pull-out resistance through screw threading processing ■ Made of stainless steel, making it resistant to rust *For more details, please refer to the PDF document or feel free to contact us.

The part where the nail contacts the tile accumulates moisture due to condensation, leading to gap corrosion. The Super Jumbo large-headed nail is a roofing nail that has its stainless steel surface coated with a special resin to eliminate contact with water, thereby improving durability. 【Features】 - To securely fix the tiles, the head diameter has been increased by 140% compared to conventional products. - Stainless steel screw ring processing has improved pull-out strength. - Special resin coating to prevent gap corrosion. ● For other functions and details, please contact us.
