[Sales/Lease] The lightweight square support column is a unit-type support structure with a permissible load of 20 tons. It is a highly versatile support structure that allows for free height adjustment!

The lightweight square support column is a unit-type support structure with a permissible load of 20 tons. The built lightweight square support column has a long history of over 40 years since its development and has a proven track record of adoption in a wide range of sites, from local general contractors to major general contractors, making it a reliable and safe long-selling product. With six different size combinations ranging from 200mm to 3000mm, it can be adjusted to various heights, making it suitable for many sites. By using φ42.7 steel pipes as the main material, it has achieved approximately 30% weight reduction compared to conventional square columns. It can be used more easily compared to H-shaped steel (raw materials or retaining materials), significantly improving workability and contributing to cost reduction in temporary construction. ■Features - The permissible load is 196kN (20 tons), which is larger than that of general support structures. - Height adjustment is freely possible by simply joining with M16 bolts. - Easier to use compared to H-shaped steel (raw materials or retaining materials). - A reliable and safe long-selling product with over 40 years of history. - Achieved approximately 30% weight reduction compared to conventional square columns. *For more details, please refer to the PDF document or feel free to contact us.

[Sales and Leasing] This is a box-type truss material suitable for large spans, usable for various applications such as "temporary roofs" and "temporary walkways" that are strong and durable.

Multi-Truss A is a box-type "long-span truss material" that can be easily assembled by simply joining dedicated joint plates with bolts and nuts. Depending on the design conditions, it can span up to 20 meters, making it widely used in large-scale repair and renovation projects that require large openings. Additionally, it has various applications and can be utilized as a "temporary walkway," "temporary roof," or "protective scaffolding" that is strong and suitable for long spans. Compared to traditional methods using heavy materials, it has fewer components and can be easily assembled, significantly contributing to cost reduction and shortening of construction periods. 【Features】 - It is widely adopted in "large-scale repair work" and "renovation work" where large openings of four spans or more are required, which cannot be achieved with beam frames. - It allows for easy assembly of strong "temporary walkways," "temporary roofs," "protective scaffolding," and "work stages" with long spans. - Simple assembly by just joining dedicated joint plates with bolts and nuts, contributing to cost reduction and shortening of construction periods. - Assembly and disassembly are performed at ground level, eliminating the risk of falls. *Case study materials are available!

[Sales and Leasing] Since it can span large distances, a "temporary work passage" can be installed easily and at low cost!

In sites with a wide excavation area, the shortest approach to the office becomes a challenge. However, many may be troubled by the fact that systems like pedestrian bridges using H-shaped steel can become quite heavy, leading to a desire to establish a work passage more simply and at a lower cost. The large-span truss material "Multi Truss A" can span 20 meters depending on the design conditions, allowing for the easy installation of a "temporary work passage" by placing scaffold boards on top. This contributes to shortening the installation period and reducing costs, and we have received positive feedback from major general contractors on site. *For more details, please refer to the PDF document or feel free to contact us.

Lease: With a simple design that has a small number of parts, it can be easily assembled even for first-timers. It achieves excellent cost performance on sites with large spans.

Multi Truss B is a "joint-type truss material for large spans" that is used as a unit by inserting pins. Depending on the design conditions, it can span 25 meters, making it suitable for various applications such as "temporary roofs," "work stages," "mobile platforms," and "walkways" that require strength over large spans. It has been widely adopted for rain protection in renovation work for shrines, temples, and historical sites. The frame-type Multi Truss B is lightweight with fewer components, allowing for easy assembly, which contributes to reduced transportation costs and shortened construction periods. 【Features】 - Capable of accommodating various applications such as "temporary roofs," "temporary walkways," and "work stages" with strength over large spans. - Can be used as a unit simply by covering the ends of the upper and lower frame members with direct joints. - Fewer components and easy assembly contribute to shortened construction periods. *Case study materials are available!

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Starting from January 2026, we are pleased to announce that by linking the measurement data collected on the "Fieldroid Cloud" with the BIM/CIM cloud "KOLC+" provided by Cork Inc., it has become possible to centrally display measurement data summaries on the digital twin. (Examples) Measurement of various environmental data using Cloud Logger LTE Forecasting wind speed, rainfall, and heat index using Signroid 2 Temperature and humidity measurement during concrete curing using Ondroid Slope monitoring using Guraloid Displacement measurement using the shape displacement measurement system "G-Gauge" The data measured by the above services is sent to the cloud, enabling graph displays and alert email notifications. With the implementation of the data linkage function, it is now possible to visualize the latest measurement data from the Fieldroid Cloud on the digital twin constructed in "KOLC+". For more details, please check the content on the linked page.

Regarding the "quotation" used at the forefront of sales activities: "Do we need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving all processes is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating interpretations from the latest National Tax Agency Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." Items sent externally are "generally required to be preserved." Items that have not been sent externally have "no preservation obligation." 2. Judgment from the sending side: "Is it linked to a transaction?" 3. Judgment from the receiving side: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to ensure reliable "version management." ■ Summary.
