The "Canopy PC" is a PCa (precast) component that is either fully PCa (precast) or a half PCa (precast) slab with truss reinforcement. It is laid on the structure (formwork), and after placing the remaining rebar, concrete is poured to achieve integration. By manufacturing it in a specialized PC factory, quality can be ensured while also allowing for simplification. 【Features】 ■ Contributes to high quality, cost reduction, and shortened construction period ■ Can be discussed together, including the feasibility of precasting ■ Reduces manpower for work at the canopy tip Please feel free to leave proposals and drawings to us. If you have any inquiries, please do not hesitate to contact us. *For more details, please download the PDF or contact us directly.

The "Kaiser Balcony Construction Method (Steel Structure)" involves fully precasting the tip of the balcony that connects to the steel frame (S structure) and using half precast panels with truss reinforcement. The tip of the balcony is complicated due to the presence of drainage channels and handrails, requiring advanced construction techniques. By manufacturing the truss-reinforced half precast panels at a specialized precast factory, we can simplify these challenging on-site tasks while ensuring high quality. This eliminates the need for cantilever beams, resulting in a cleaner finish. Feel free to leave proposals and drawings to us. If you have any inquiries, please do not hesitate to contact our company.

The "Kaiserslave Method (Steel Structure)" is a construction method where truss-reinforced half precast (PCa) slabs manufactured in a precast factory are laid on a steel frame (steel structure) at the construction site. After reinforcing the remaining rebar on top, concrete is poured to construct the floor. The truss-reinforced half PCa slabs also serve as formwork, reducing the need for temporary materials and ensuring a safer site environment with fewer materials. The ceiling surface will be finished in concrete. Feel free to leave proposals and drawings to us. If you have any inquiries, please do not hesitate to contact us.

The "Parapet PC (Steel Structure)" is a building material that achieves a reduction in construction time and an improvement in construction quality through the full precasting (full PCa) of parapets installed at the top floor.

The "Kaiser Railway Elevated Bridge Slab" is a rational slab that uses high-quality precast (PCa) components manufactured in a factory, allowing for the construction of elevated bridges that excel in durability and cost-effectiveness, and is installed on cast-in-place beams. Since the lower half of the slab cross-section is made of PCa, it can be constructed directly above live lines. Additionally, by casting the upper half of the slab on-site, the structure becomes integrated. The intermediate and cantilever sections are unified, eliminating the need for formwork and shoring. Compared to conventional cast-in-place slabs, it reduces construction noise and material yard requirements, contributing to shortened construction schedules and reduced total costs. Please feel free to contact us if you have any inquiries. 【Features】 ■ Shortened construction schedule ■ Possible to construct directly above live lines without shoring ■ Reduced life cycle costs ■ Existing slab designs can be directly applied ■ High safety ■ Uniform quality ■ Improved quality of structures
