Non-protruding rock bolt head anchoring component.

NETIS Registration Number KK-110058-A ■Features of the Flat Cap, a Head Fixing Component for Non-Protruding Lock Bolts 1. Provides a Clean Aesthetic Offers a neat appearance on reinforced slopes. 2. Creates a Safe Environment Prevents damage from falling rocks or contact with vehicles from above the slope. It is safe to use on slopes facing roads as there is no contact with pedestrians or vehicles. 3. Reduces Maintenance Since leaves, driftwood, and debris do not get caught, maintenance work is minimized. 4. Easy Maintenance of Slopes The blades of grass cutters do not come into contact, so they do not obstruct maintenance work on slopes. 5. Economical Conventional reinforcement materials can be used as is, and the number of parts for head treatment is reduced, making it cost-effective. 6. Usable by Anyone There are no restrictions on the installer, so anyone can use it.

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.

Our representative, Koichi Yokoyama, will be speaking at an online seminar scheduled for November 27 (Friday). Participation is possible from anywhere in the country.
