Market Development History

In the 1990s, the market relied primarily on heavy steel frames and wooden inserts, which suffered from rapid oxidation and poor thermal performance during the harsh northern winters.

By the mid-2010s, basic aluminum profiles began to replace steel. However, these lacked insulation, leading to significant heat loss and condensation issues within residential buildings.

From 2020 onwards, the focus shifted toward Casement windows construction utilizing reinforced aluminum alloys, integrating gaskets and multi-point locking systems for airtight sealing.

Future Development Trends
