Modular windows and doors made of colored steel 65 series
The technology was created as part of R&D initiated by the Ministry of Construction of the People's Republic of China. These are not just windows, but the result of the introduction of scientific achievements at the state level. Each window carries the technical authority of the enterprise - the developer of state standards of the People's Republic of China.

Maximum thermal insulation
Say goodbye to high energy costs! Thanks to the 75 series of five-chamber construction with double polyurethane filling, the heat transfer coefficient reaches only 0.89 W/(m² K), which significantly exceeds the requirements of the new Russian energy efficiency standards of 2025. Your home remains warm and cozy even at -50 °C.
Development at the level of state standards

These are not just windows, but the result of the introduction of scientific achievements at the state level. Each window carries the technical authority of the enterprise - the developer of state standards of the People's Republic of China.
Double protection
On the outside there is an indestructible steel sheet with a polymer coating, on the inside there is a warm and pleasant-looking multi-chamber PVC profile, and between them there is a highly effective polyurethane layer that reliably breaks cold bridges. The strength of steel and the thermal insulation of plastic are ideally combined, completely solving the problems of condensation and frost heaving.
Environmental certification
Specially developed for “gold” and “silver” green buildings. High air permeability (class I–II) and water resistance (class III) help buildings easily pass environmental certification according to GOST standards, setting new trends in energy saving in Russian construction.
Where steel meets heat
Huaxia composite steel-plastic window - an ideal heat shield for the polar regions
Modular windows and doors made of non-ferrous steel: by combining multi-chamber plastic thermal insulation material with steel profiles facing the internal and external sides, a composite profile is formed that carries the load. This design fully combines the high strength of steel and the thermal insulation properties of plastic. Thanks to the polyurethane connecting layer, a reliable connection of various materials is ensured, which can effectively reduce the influence of temperature stresses on the structure, and the strength of the structure meets the requirements of conventional construction. The use of polyurethane and PVC with low thermal conductivity allows you to effectively block the path of heat transfer through the metal frame, which significantly increases the thermal insulation characteristics of doors and windows. The thermal conductivity coefficient of polyurethane is only about 0.25 W/mK, which is about 700 times less than that of ordinary aluminum alloy, making the thermal insulation effect extremely significant; Thanks to the interaction of the multi-chamber structure and PVC material in combined structures, more effective suppression of thermal bridges and more outstanding thermal performance are achieved.
