It operates a 1,368 m² manufacturing plant with six production lines, 45 employees, and 11–20 quality-control staff. The supplier reports ISO 9001:2015 certification and has exported since 2008, with 71%–90% of sales attributed to exports. Its stated capabilities include customization, quality assurance, technical support, and long-term customer relationships, but evidence for after-sales service, specific customer cases, and innovation depth is limited.

Its stated business scope and product portfolio focus on door hardware, locks, hinges, closers, exit devices, and related construction hardware, indicating a manufacturing-oriented supplier rather than only a trading entity.

Production capacityThe supplier reports a 1,368 m² manufacturing plant, six production lines, and 11–20 quality-control staff, alongside a broad door-hardware product range. These details provide explicit evidence of an established production setup, although capacity utilization and delivery performance are not stated.
