Business Details

Provides special-material welding and wear-resistant overlay welding construction for production facilities and equipment across various industries, mainly steel and automotive. Key customers are major steel manufacturers such as Nippon Steel and JFE Steel. Strengths lie in special-material welding beyond mild steel—including stainless steel, nickel alloys, and wear-resistant materials—and overlay welding technology aimed at regenerating and extending the life of equipment parts. Also engaged in the manufacture and installation of top plates (wear-resistant clad steel plates). Net sales to external customers for FY2026 (ending March 2026) were ¥8,134 million, accounting for 74.5% of consolidated net sales.

Recent Overview

Net sales increased as growth in steel-related maintenance works offset the decline in top plate works, but profit declined due to rising costs.

In the Construction & Installation Works segment for FY2026 (ending March 2026), orders for Top Plate Construction decreased, while orders for steel-related maintenance works increased, resulting in net sales of ¥8,134 million (up 1.9% year on year), securing sales growth. However, segment profit declined to ¥1,136 million (down 4.1% year on year) due to rising raw material prices driven by increases in logistics, energy, and labor costs. Net sales to key customer Nippon Steel fell sharply to ¥1,428 million from ¥1,836 million in the prior period, while net sales to JFE Steel were newly disclosed at ¥1,322 million as a key customer. No impairment loss was recorded in the Construction & Installation Works segment this period, compared with ¥21 million recorded in the prior period.

Key Products

service
Wear-Resistant Overlay Welding Construction

Regenerates and repairs equipment parts worn beyond their usable limits through overlay welding using special welding materials. Deployed across industries such as steel, cement, and chemicals, contributing to equipment life extension and cost reduction.

service
Top Plate Construction

Uses in-house-manufactured wear-resistant clad steel plates to perform wear countermeasure work on conveyance equipment, hoppers, and other equipment. In FY2026 (ending March 2026), orders for Top Plate Construction decreased, but this was offset by an increase in Steel-Related Maintenance Works.

service
Steel-Related Maintenance Works

Regular maintenance and emergency repair work for production facilities of major steel manufacturers such as Nippon Steel and JFE Steel. Orders increased in FY2026 (ending March 2026), offsetting the decline in Top Plate Construction and contributing to overall sales growth.

service
Grinding Mill Works & Continuous Casting Roll Overlay Works

Highly specialized construction work requiring advanced technical capability, including overlay welding on grinding mill rollers and tables, and regeneration welding of rolls in continuous casting equipment. Long-accumulated technical expertise and skilled engineers are the source of competitive differentiation.

Growth Drivers

  • Sales supplementation through increased orders for steel-related maintenance works (FY2026, ending March 2026 results)
  • Cost reduction and order expansion through proactive proposal-based sales and provision of advanced technology
  • Deepening relationships with existing customers and developing new industries against a backdrop of demand for equipment regeneration and life extension
  • Stable order intake through a diversified customer base spanning multiple major steel manufacturers including JFE Steel
  • Improved construction quality and sustained competitive advantage through advancement of technology transfer

Risks

  • Risk of sales concentration in the steel and automotive industries (Nippon Steel and JFE Steel combined account for approximately 25% of consolidated net sales)
  • Risk of declining orders for specific types of construction work such as Top Plate Construction (declined in FY2026, ending March 2026)
  • Risk of margin decline due to soaring raw material prices amid rising logistics, energy, and labor costs
  • Customer concentration risk, as net sales to key customer Nippon Steel declined sharply by 22.3% year on year
  • Risk of increasing difficulty in securing skilled engineers and passing on technical expertise
  • Risk of rising raw material prices due to deteriorating conditions in Ukraine and the Middle East and export restrictions by China
