Four-tongue-and-groove Metal Curtain Wall - the Preferred Choice for High-end Intelligent Industrial Exterior Walls

Four-tongue-and-groove Metal Curtain Wall - the Preferred Choice for High-end Intelligent Industrial Exterior Walls

Modern buildings are developing rapidly towards intelligence and high density. The precision of production equipment and the high added value of stored materials have put forward higher technical requirements for the fire protection performance of building envelope systems.

The traditional sandwich panel structure is difficult to meet the fire protection requirements of scenarios such as precision electronic factories, high-value logistics centers, and public buildings due to its defects such as high-temperature structural collapse and core material segmented fracture.

Four-sided industrial curtain wall panels

The HXY-FD-W-SHEB four-groove pure rock wool metal curtain wall panel is a new panel type system developed by Hongxinyuan based on the four-groove curtain wall sandwich panel system. Its most prominent feature is that the core material is pure rock wool, which has been successfully applied to various high-end industrial building projects.

Pure rock wool core material, with better fire resistance

The four-groove design, combined with pure rock wool core material, builds multi-level fire barriers both horizontally and vertically, effectively eliminating the fire combustion caused by insufficient fire resistance rating in traditional curtain walls.

The systematic upgrade of material properties is achieved through fiber orientation optimization and physical consolidation processes. Grade A rock wool core material forms a physical fireproof isolation belt, ensuring zero spread of fire. It can meet the fire protection requirements of various factories, maintaining stable heat insulation performance while safeguarding building safety, achieving a dual-effect synergy of fire prevention and energy 

conservation.

Prefabricated assembly process

The plates are assembled using a non-welding process, and precise alignment is achieved through mechanical interlocking, eliminating the risk of thermal deformation caused by traditional welding. The standardized prefabricated components are designed with fastening groove lines at the system sockets, significantly reducing the impact of human factors on the project quality. This enables the super-large-scale facade to achieve ultra-high flatness assembly, meeting the rapid construction or renewal requirements of the factory building.

The innovative value of the modular assembly process lies in precisely aligning the fire compartment planning of buildings with the division of curtain wall units. The pure rock wool core material of each curtain wall unit naturally forms a physical fire boundary, effectively curbing the spread of fire across units when a fire occurs, making the building facade the spatial carrier of the active defense system.

The facade language of coexistence of hardness and softness

The aesthetic expression of the curtain wall system is deeply integrated into the functional design. The tongue-shaped slot connection technology without exposed bolts fully releases the structural load-bearing capacity of the pure rock wool core material, eliminates the visual fragmentation brought to the building by exposed connection parts, makes the horizontal lines the core visual element of the building facade, and endows the building with a unique order aesthetics.

The introduction of arc-shaped corner plates enables a natural transition of the building outline from rigid straight lines to smooth curves, while enhancing the wind resistance performance of the corner structure. The interweaving of matte metallic texture and horizontal ton-and-tongue lines creates a facade rhythm that combines hardness and softness, allowing the industrial building to exude warmth and tension.

All-dimensional performance integration

The geometric combination characteristics of the modular units in the curtain wall system support the building facade to find a balance point between standardization and customization, making the building a spatial extension carrier of the enterprise brand.

Through the three-dimensional synergy of structural innovation, material selection, and process upgrading, Kewangde ® four-sided pure rock wool metal curtain wall panels have established a composite building envelope system defense system that covers fire isolation, structural stability, convenient maintenance, and energy conservation and efficiency improvement, providing buildings with an envelope system solution that takes into account both safety defense and long-term operation.
