01
Thermal-break approach
View details
A carbon-steel thermal-break concept is used to reduce direct heat-transfer paths through the entrance structure. The applicable section design and thermal data are confirmed for the selected configuration.
Technology & construction
Comfort, performance and security in one entrance system
Technology overview
The 2026 catalogue presents a carbon-steel thermal-break approach, multi-stage sealing and a layered insulated door leaf. Exact construction and performance depend on model, size, hardware and test configuration.
02
Sealing & insulated core
View details
Multiple sealing lines, dense core materials, insulation layers and controlled joints are presented as a coordinated strategy for air, sound and temperature control.
03
Whole-entrance review
View details
Performance is not assigned to the door panel alone. Frame, threshold, hardware, glazing, installation interface and smart access are reviewed as one entrance system.

Section overview
The images below are carried over from current China-market company material. They explain the construction intent; the approved section drawing, bill of materials and matching evidence define the quoted product.
01
45° rebated interface
View details
A 45-degree rebated interface increases the contact path between leaf and frame and is intended to improve compression at the seals. Air, water and acoustic results depend on the complete tested assembly and installation.
02
PA66 GF25 thermal break
View details
A PA66 GF25 polyamide insulating strip separates interior and exterior metal sections. Company material states a reference thermal conductivity of approximately 0.25–0.30 W/(m·K); final section design and evidence remain configuration-specific.
03
Reinforced composite leaf
View details
A reinforced composite leaf coordinates the visible facing, internal metal reinforcement, insulating infill and secure hardware fixing. The layer stack is selected by model, size and intended performance rather than treated as one universal construction.
04
Polyurethane insulated infill
View details
The reference door leaf uses polyurethane foam to fill irregular cavities and support continuous insulation. The catalogue identifies a low-conductivity polyurethane material; formulation, fire behaviour, emissions and thermal data must be supported by the current supplier and product documents.
Additional interfaces
Steel frame reference
View details
The published reference uses precision-formed galvanized steel as the structural frame base. Company material identifies a 2 mm sheet and a Z275 coating reference; material certificates and the applicable standard should be checked for the quoted configuration.
Frame-to-wall insulation
View details
Company technical material also references extruded polystyrene insulation at the frame-to-wall interface, with a stated conductivity below 0.030 W/(m·K). Suitability, fire requirements and installation detail must be resolved for the destination project.

Patent references
View details
China patent references listed in the 2026 catalogue: ZL202420357713 and ZL202421539559.7. Scope and legal status should be confirmed from current documents when material to a project.
Performance evidence
View details
Published performance values apply only when supported by an identified test report and matching product configuration. Ask the sales team for thermal, acoustic, fire, weather or security documentation relevant to your destination.
Hardware integration
View details
The catalogue includes concealed-hinge and integrated access-control options. Load rating, opening angle, power, lock body and service access must be matched to the final door size and local requirements.
Finish approval
View details
Colour and surface samples are available as a starting palette. Approval should be based on a physical sample or agreed control reference because screen colour and production batches can vary.
