Based on the French vintage design concept, HSTM combined with the redesign and improvement of the profile structure, vertical iso-thermal design, three sealing improvements as well as EPDM composite rubber strips, not only to integrate and maintain the French romantic mood and the original classic French retro style, but also enhance the overall performance of the product such as waterproof, sound insulation and heat preservation. French vintage steel windows are marketable because they combine aesthetic, functional, and sustainable benefits, meeting the diverse needs of modern living and design.

H72 broken bridge single inward opening window Luxembourg series rectangular cavity structure design, the connection is firm and stable, the indoor and outdoor are coplanar, the inside and outside of the window sash are flush and the gap between the frame and sash is perfectly hidden, the visual effect is beautiful, the heat insulation and waterproof function is outstanding, there are inner flat opening.

H88 broken bridge window screen integrated double inward opening window is a broken bridge aluminum door and window that combines the heat insulation function of the broken bridge window, the insect protection function of the gauze curtain and the double inward opening design window type. There is a heat-insulating "broken bridge" in the middle of the window frame, which can effectively reduce heat conduction and improve the heat-insulating performance of the window. Screen curtains on windows are usually used to prevent insects from entering the room while maintaining air circulation. The window frame and window sash are integrated and can open two doors inward. It can be cleaned and maintained more conveniently, and it also facilitates the exchange of indoor and outdoor air.

The integrated external opening window with broken bridge screen refers to the use of thermal bridge aluminum profiles in the frame of the window. This design can effectively isolate the cold and heat conduction indoors and outdoors, improve the thermal insulation performance of the window, and prevent the impact of indoor and outdoor temperature differences on the interior. Screen windows can be used to prevent mosquitoes, flying insects, etc. from invading the room and maintain indoor ventilation. The entire window design is integrated and can be opened outwards. This design allows for better ventilation and makes cleaning and maintenance of the windows easier.

HSTM outward-opening windows utilize a multi-cavity structure, combined with glue injection, to make the overall frame structure more stable than ordinary outward-opening windows. At the same time, they adopt integral built-in Roman crimping and europium aluminum corner codes, which are suitable for different processing habits and processing equipment. HSTM has developed three types of large and small buckles, which can effectively realize the buckle conversion of over-large glass. The glass adopts a middle sealing structure to eliminate the hidden danger of water leakage from the buckle strips and ensure air tightness, heat insulation and sound insulation.

H120 broken bridge window screen integrated French retro window has an elegant, refined, traditional French style. It is made of 6063-T5 aluminum. Thermal bridge technology separates the indoor and outdoor metal window frames to improve the thermal insulation performance of the window. It is equipped with medical grade stainless steel screen. Net, highlighting French and retro design elements, with optional manual/electric opening methods.

HSTM smart lift window is made of broken bridge 6063-T6 aluminum. Users can remotely control the opening and closing status of the window through the remote control or smartphone application and automatically open or close at a specific time. It has an intelligent infrared sensing system and can Function configuration board, remote control, mobile APP, AI voice function and other intelligent controls can effectively manage indoor temperature.
