Business
Chubu Steel Plate Co., Ltd. was founded in 1950 and has its head office and plant in Nakagawa Ward, Nagoya City, making it Japan's only steel plate manufacturer specializing in electric furnace operations. Its core business, the Steel-related Business, melts steel scrap (its main raw material) in an electric furnace and manufactures and sells steel plate products through an integrated process of continuous slab casting and plate rolling. The company comprises four segments in total: the Rental Business (Grease Filter Rental Service and advertising signboard rental), the Logistics Business (Transportation & Cargo Handling Business and Hazardous Materials Warehousing Business), and the Engineering Business (Plant Design & Construction and maintenance). Its main customers are steel distribution trading companies (Hanwa Co., Ltd., Nippon Steel Trading Corporation, Metal One Corporation, etc.) serving the industrial machinery, construction machinery, architecture, and shipbuilding industries, and the company achieves timely supply through a made-to-order production system. It is listed on the Prime Market of the Tokyo Stock Exchange.
Business Model
Molten steel is produced in an electric arc furnace using steel scrap as the main raw material, and Steel Plate Products are manufactured through continuous casting and rolling processes. By adopting a make-to-order production system, the company suppresses inventory risk while leveraging the electric-furnace characteristics of short lead times, small lot sizes, and multi-product capability to supply the market in a manner that complements blast furnace producers. The Steel-related Business accounts for approximately 95% of net sales, with the metal spread (the difference between the selling price and the raw material scrap price) serving as the primary earnings driver. The group of subsidiaries supports intra-group demand while also generating external revenue.
Company Strengths
The company is the only manufacturer in Japan specializing in steel plate production using electric furnaces. It has accumulated advanced operational technology over many years, enabling it to produce steel plate grades typically handled by blast furnace manufacturers using electric furnaces. Its proprietary products, such as machinability-improved steel plate and steel plate for laser cutting, are highly regarded in the market. This scarcity has created a position free from competition, forming the foundation for stable order intake.
By thoroughly adhering to a make-to-order production system, the company maintains a structure that produces and ships ordered products in a timely manner. It has built ongoing business relationships with major distribution trading companies such as Hanwa Co., Ltd. (sales of ¥6,418 million, 12.6% of composition), Nippon Steel Trading Corporation (¥5,409 million, 10.6%), and Metal One Corporation (¥5,408 million, 10.6%), maintaining stable order intake.
Net assets reached ¥75,736 million (at the end of FY2026, ending March 2026), and the company maintains debt-free management, with a basic policy of funding both capital expenditures and working capital through internal funds. Through CMS (Cash Management Service), surplus funds within the group are centrally managed, enhancing capital efficiency. Its stable dividend policy, targeting a DOE of 3.5%, also demonstrates a high level of financial discipline.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥76,320 million in FY2023 (ending March 2023) before declining sharply to ¥51,047 million in FY2025 (ending March 2025), then showed signs of bottoming out in FY2026 (ending March 2026) at ¥51,103 million, roughly flat (up 0.1% year on year). Meanwhile, operating profit plunged for three consecutive periods, from ¥12,261 million in FY2023 (ending March 2023) to ¥923 million in FY2026 (ending March 2026), with the operating margin falling to 1.8%. The primary external factor was the decline in steel plate selling prices amid deteriorating steel market conditions; the decline in selling prices exceeded the decline in steel scrap prices, narrowing the metal spread. Although sales volume exceeded the previous period's level due to the normalization of operations at the new electric furnace, this was not enough to absorb the impact of the price decline. Operating cash flow swung from an inflow of ¥21,525 million in the previous period to an outflow of ¥5,839 million, mainly due to an increase in trade receivables of ¥5,768 million and an increase in inventories of ¥5,083 million. Comprehensive income improved to ¥2,432 million (versus ¥1,514 million in the previous period), aided by improvements in valuation difference on available-for-sale securities and remeasurements of defined benefit plans.
Growth Strategy
Centered on the full-scale operation of the new electric furnace, the company aims to enhance corporate value through three pillars: sales volume recovery, decarbonization, and improved capital efficiency
The new electric furnace, which had recovered from a molten steel leakage accident in the previous fiscal year, achieved stable operation in FY2026 (ending March 2026), with sales volume recovering to a level exceeding the previous fiscal year. The company will continue to pursue efficient operations that maximize the performance of the new electric furnace, along with cost reductions, aiming for a recovery in profitability through improvement in the metal spread. For FY2027 (ending March 2027), net sales are projected at ¥69,600 million (up 36.2% year on year).
By obtaining Green Steel and EcoLeaf certification, leveraging the low-CO₂ characteristics of the electric furnace process, the company aims to respond to decarbonization demand and enhance product added value. It will continue its efforts to reduce environmental impact, including CO₂ emission reductions, and pursue a differentiation strategy that meets customers' needs for diversifying their procurement sources.
In February 2026, the company decided on a policy to reduce consolidated equity capital to approximately ¥700 million (from ¥749 million at the end of March 2026) by the end of FY2027. In May 2026, it resolved to conduct share buybacks (up to 900,000 shares / ¥1,700 million), and combined with an increased dividend (projected at ¥113 for FY2027 (ending March 2027)), it aims to strengthen shareholder returns, thereby improving capital efficiency and achieving sustained enhancement of corporate value.
