With the continuous expansion of cities, the ongoing industrial revolution, and the constant upgrading of automation technology, the call for industrial transformation is growing louder. The rapid development of multi-story and high-rise steel structures has placed higher demands on project schedules and quality. The floor slab construction methods, particularly during the construction phase, are often a crucial factor affecting the project schedule.

Precast concrete components are almost ubiquitous, but in super high-rise buildings, the increased cost and reduced construction efficiency when using PC structures to achieve high assembly rates are issues that need to be considered. Precast steel trusses, as an indispensable component of modern precast buildings, play a crucial role in the overall project.

Prefabricated steel trusses are formed by three straight steel bars arranged in a triangle and connected by resistance spot welding of two long, wavy, curved web bars. The steel bars are of various types and have stable spacing, making them suitable as connecting bars between thin concrete slabs and secondary cast-in-place sandwich concrete. Composite floor slabs using steel trusses can withstand greater shear stress.

The truss steel bars produced by Zhonggou have the following main characteristics:

1. Automated equipment production results in low waste, high capacity, low labor costs, and a clear competitive advantage for the products;

2. The truss has a reasonable stress distribution mode, uses economical materials, and has a significant overall cost advantage;

3. The amount of on-site rebar tying work is reduced by 60% to 70%, further shortening the construction period;

4. High-quality main and auxiliary materials supply, automated equipment production, and stable product quality;

5. Adjust the truss height and steel bar diameter to suit floor slabs with larger spans;

6. Its mechanical properties are basically the same as those of traditional cast-in-place concrete, and it has good crack resistance;

7. Factory production eliminates the impact of large-scale gatherings, effectively ensuring the construction period;

8. Standardized design and information-based management of production, with no construction waste during on-site assembly.

Before focusing on the future, we must first focus on the present. Zhonggou New Materials has been dedicated to the steel decking field for over 20 years. Through participating in numerous well-known high-rise building projects in China, we have continuously optimized our R&D standards and processes, forming an integrated industry-academia-research system.

Zhonggou New Materials' production base starts from the source of raw materials, and quality inspection runs through the entire process from main and auxiliary materials to molding and processing, and factory packaging, ensuring the reliable quality of Zhonggou buildings. By eliminating factors that increase material costs and reducing customers' later maintenance expenses, the product has been widely used. Zhonggou New Materials' steel trusses play an irreplaceable role in prefabricated assembly projects.

Zhonggou New Materials has multiple advanced domestic steel decking production lines with a monthly production capacity of nearly 500,000 square meters, and possesses stable contract fulfillment capabilities and cycle guarantees.

These products have a wide range of applications, and are widely used in various floor slab systems, including high-rise steel structure floor slabs, reinforced concrete structure floor slabs, and precast reinforced concrete floor slabs. They are also extensively used in various building applications, such as irregular floor slab structures (circular, elliptical, and other shapes), large-span structures, dropped slab structures, thick slab structures, sloping roofs, and residential steel structures.
