Modular windows and doors made of colored steel 75 series
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.

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
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.
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.

Brackets
This series of brackets is made according to a modular principle, which ensures quick installation and flexible adjustment. The brackets are suitable for fixing various industrial equipment. The main material is high-strength Q345B steel, the load-bearing capacity significantly exceeds industry standards. The thickness of the zinc coating is at least 80 microns, which guarantees protection against corrosion caused by deicing agents in Siberian winter conditions.
Fencing
This fencing system has a double anti-corrosion coating: hot-dip galvanizing + powder painting. Fences can be used for a long time in conditions of coastal salt fog or industrial pollution without fading or peeling. The distance between the posts and the height of the horizontal handrails strictly comply with GOST safety requirements. The design is anti-climbing, effectively preventing accidental falls.
Stainless steel water pipes
Pipes are made of food grade stainless steel 304/316L. The internal surface is smooth, without burrs, which ensures low hydraulic resistance and low tendency to form deposits. The pipes are especially suitable for heating and hot water systems in cold regions. Welding is performed using automatic argon arc welding, the seams are smooth and tight.
Steel bed
This steel bed is welded from cold-rolled square tubes. The design is stable, does not make creaks, and can withstand loads of up to 300 kg or more. The surface is treated with electrostatic spraying - the coating has high adhesion, wear resistance and scratch resistance, does not peel off or rust even in conditions of high humidity or low temperatures.
Steel building structures
This is one of our core competencies. Based on our experience with large enterprises such as Changan and Weichai, we specialize in the construction of heavy steel frames for buildings with long spans and high loads. From single-span (portal) frames to multi-story steel frame structures, we not only ensure that the stringent load-bearing requirements of large equipment (such as stamping lines and general assembly) are met, but also that they are fully compatible with complex industrial piping and crane girder systems.
