Through STANDARDIZED design and AUTOMATIC high-quality production, we fabricate building components for efficient delivery and on-site installation. This streamlined process enables remarkably fast and precise construction.

HHBT 2nd-Gen Steel-Concrete Building System

The 2nd-Gen Steel-Concrete Building system integrates the strengths of prefabricated steel and precast concrete. Its key components—steel columns, steel beams, UTS floor slabs, and concrete wall panels, are precision-engineered off-site. Unlike traditional construction, HHBT's precast concrete components do not require secondary casting casting work on site. This approach significantly enhances construction efficiency, making it the optimal solution for fast-track projects that demand both speed and high-quality modern standards.
HHBT SEP (Stepped-End-Plate) Building System

Our SEP system represents a leap forward, featuring the world's first weld-free structural method. Building on our 2nd-Gen system, it upgrades the steel structure to enable rapid, fully-bolted assembly while retaining precast concrete (PC) components.

Its key innovation is a connection design that ensures seamless installations;this results in outstanding seismic resilience and maximizes site efficiency, making the SEP system an ideal choice for modern structures up to 50 meters.

System Composition

+ Beam-column Joint Node

Beam-column Joint Node

HHBT's SEP system uses a specially designed node for beam-column connection. The nodes categorized into L, straight, T, and cross types. These nodes provide a fully bolted and weld-free construction, offering extremely fast speed and high efficiency!

+ Steel Column

Steel Column

The Stepped End-Plate column features flange plates at the bottom and SEP system joints at the top, enabling truly prefabricated construction.

+ Steel Beam

Steel Beam

The Stepped End-plate beam allows for a fully bolted column-beam connection, without any onsite welding.
+ UTS floor slab

UTS floor slab

HHBT UTS floor slab adopts modular design, with built-in steel mesh, and the stress calculation is consistent with traditional cast-in-place floor. Through factory prefabrication, the on-site pouring process is perfectly eliminated, achieving rapid installation.

+ Wall Panel

Wall Panel

HHBT's large wall panels utilize solid waste concrete as raw material, supporting ultra-large prefabrication up to 8 meters wide. They offer advantages such as flexible installation, robust safety, stable quality, and convenient construction.
+ Foam Ceramic Panel

Foam Ceramic Panel

HHBT, through secondary scientific processing of solid waste materials, has developed a green product-foamed ceramic, which is flame-retardant, soundproof, waterproof, moisture-proof, lightweight, and carvable. It has wide applications in interior decoration, exterior wall decoration, and exterior wall insulation panels.
