2025 Pouring Test Successfully Completed at TECON Nantong Manufacturing Base

In 2025, TECON officially announced the upgrade of two of its best-selling formwork systems—HETO Frame Formwork and the Alu-Flex Framed Formwork System—further improving performance, installation efficiency, and on-site adaptability. At the same time, TECON confirmed the development of a new aluminum beam–based slab formwork system, APEX DEK, designed to meet growing demands for lightweight, high load-bearing, and flexible slab construction solutions.

All upgrade and development work was led by TECON’s R&D team. Through multiple rounds of structural calculations, design optimization, and repeated testing, the team ensured that each system met both engineering requirements and practical jobsite needs, delivering market-ready solutions.

The concrete pouring test served as a direct performance demonstration for clients, clearly presenting the construction results achievable with TECON’s newly upgraded and developed formwork systems.

System Highlights

HETO Frame Formwork 3.0

The upgraded HETO system adopts 15 mm TECON-Form birch plywood and introduces a cost-effective non-adjustable mini clamp alongside existing adjustable clamps. This upgrade enhances overall strength, stability, and installation efficiency while effectively reducing system cost.

Alu-Flex Slab Formwork

The upgraded Alu-Flex system features unified profiles to minimize material waste, a lighter welded-and-bolted connection replacing heavy cast components, and a redesigned early-release support head reduced from 382 mm / 6.14 kg to 311 mm / 4.36 kg. Optimized profiles and filler beams compatible with modular aluminum beams further improve handling efficiency and on-site flexibility.

APEX DEK Aluminum Beam Slab Formwork

APEX DEK is a modular aluminum beam slab formwork system with standardized components for fast assembly and dismantling. The system allows early striking once concrete reaches the required strength while retaining vertical supports to enable rapid formwork turnover. Precise slot connections ensure simple, training-free installation, and full compatibility with the Alu-Flex system protects existing investments while supporting mixed-use and system upgrades.

Pouring Test Configuration

The concrete pouring test was based on a column–slab–beam structural model, simulating typical construction conditions. The setup included six square columns (500 × 500 mm) and one rectangular column (750 × 1650 mm), with 300 × 450 mm beams and a T-shaped wall configuration. The structure featured a 3.0 m floor height, 250 mm slab thickness, and 300 mm wall thickness.

The HETO system was applied to wall and column sections, while the slab area used a combined solution of Alu-Flex and APEX DEK, ensuring stability, efficiency, and adaptability throughout the pouring process.

The total test land area covered 62.64 m², with an actual concrete pouring area of 42.12 m².

The evaluation covered load-bearing capacity, component functionality, deformation response, and validation of finite element predictions against laboratory and on-site pouring measurements.

Pouring Test Results

Based on full-process monitoring and analysis of the combined Alu-Flex and APEX DEK pouring test, together with the evaluation of the HETO formwork system, the results confirm that all systems fully meet strength, functional, and construction requirements under real jobsite conditions. The formwork systems performed reliably with stable structural behavior, consistent deformation trends, and effective load transfer. Overall, the test validates the safety, reliability, and engineering soundness of TECON’s upgraded and newly developed formwork solutions, confirming their readiness for practical application.

The successful completion of the 2025 pouring test further demonstrates TECON’s strong R&D capability and commitment to delivering reliable, high-performance formwork solutions. These validated systems provide customers with proven, efficient, and adaptable options for a wide range of concrete construction applications.
