The Material Solution Group, Industrial Materials DX Department of Mitsubishi Corporation (hereinafter "Mitsubishi Corporation") has released new functions for fabricators in its mill sheet digitization and management service, "Mill-Box."
This release not only enables centralized management of mill sheet data but also allows for the instant creation of management documents, such as tally sheets and summary lists, based on mill sheet information. This will contribute to operational efficiency and the reduction of working hours in steel logistics.
## Background
### The heavy burden of creating management documents for fabricators
For steel fabricators handling steel frames, tasks related to mill sheets (documents certifying the quality of steel materials) continue to be a significant burden. In particular, the manual process of aggregating large volumes of mill sheet information generated for each project and creating summary lists and tally sheets in the formats specified by each company requires a great deal of time and effort. The occurrence of transcription errors and the need for verification checks due to manual entry not only pose a risk to quality control but also squeeze the time that should be devoted to core business tasks.
The conventional Mill-Box lacked functions specifically designed to create tally sheets and summary lists tailored to submission formats, and it had not yet succeeded in reducing the burden of document creation tasks for steel fabricators.
With the increasing adoption of Mill-Box by general contractors and the growing efficiency of tasks related to reinforcing bar mill sheets, there are high expectations for steel fabricators to also adopt Mill-Box and smoothly facilitate data integration within projects. Against this backdrop, we have been developing new functions to automate and streamline the "creation of summary lists and tally sheets."
## Function Introduction
### Functions for Fabricators
The newly released functions for fabricators were developed to solve these challenges. Mill-Box can now not only centrally manage mill sheet data but also instantly create management documents, such as tally sheets and summary lists, based on that information.
This significantly reduces the man-hours required for management document creation, which previously took a lot of time for manual work, transcription, and verification, and is expected to produce the following effects:
- Reduction of working hours by cutting down the time required to create management documents
- Quality improvement by minimizing manual entry and transcription errors
- Shifting operations to core tasks by compressing incidental work.
This release not only enables centralized management of mill sheet data but also allows for the instant creation of management documents, such as tally sheets and summary lists, based on mill sheet information. This will contribute to operational efficiency and the reduction of working hours in steel logistics.
