Taiping® Post-Tensioned Integrated Floor for Sichuan Zhongyan Shifang Cigarette Factory Relocation Project

Traditional industrial floors have numerous control and construction joints, leading to edge spalling that disrupts forklift and AGV operations. Clean, heavy-load, high-traffic environments demand superior flatness, durability, and low maintenance. Floor solutions must be evaluated considering load, subgrade conditions, production workflow, and lifecycle costs.

The Taiping® post-tensioned integrated floor system reduces joint count by approximately 80%, minimizing edge damage, dust, step displacement, and production interruptions. The ST-NSM anchorage system, developed by Shente Materials, ensures reliable post-tensioning performance. Finite element analysis was used to design the foundation-floor interaction for safety and economy.

Clean industrial facilities (pharmaceuticals, tobacco, food) face two floor problems: (1) numerous control joints due to concrete's low tensile strength, (2) floor cracking compromising cleanliness and product quality. The Taiping® post-tensioned integrated floor system offers a low-carbon, joint-reduced solution.

Project Overview: The post-tensioned floor covers approximately 25,000 m² with a design load of 3.0 t/m². The floor was divided into 9 construction zones based on functional areas, load distribution, soil conditions, and construction logistics. The largest single pour measured 120 m in length and 6,300 m² in area.

Key Features:

• Joint-Reduced Design: The post-tensioned floor slab acts as a fully compressed element, compensating for concrete's low tensile strength and enabling large-area, joint-reduced construction.
• Cleanliness: fewer joints mean fewer dust traps and less maintenance.
• Finite Element Analysis: Combined with geotechnical data, code requirements, and functional zoning, finite element analysis ensured safe, reliable, and economical design of the foundation-floor system.
• ST-NSM Anchorage System: developed by Shente Materials for post-tensioned integrated floors.
• BIM Visualization: 3D BIM technology was used for layout and construction detailing, ensuring quality compliance.

Construction took about one year.

Selection notes:

• The Taiping system includes three technology lines: post-tensioned integrated floor (for industrial facilities, underground garages and cold storage), UHPC integrated floor, and UHPC long-life repair (for cold chain warehouses, industrial facilities, and underground garages).
• Shente Materials should be selected based on specific structural system, floor type, and project conditions.

The project achieved a maximum single-pour area of 6,300 m² with a length of 120 m.
