Key Features & Advantages

• Lightweight & Easy Handling: 30% lighter than traditional steel formwork, manually transportable by 2 workers, eliminating dependence on heavy hoisting equipment and saving construction time in high-rise and narrow-space projects.
• High Strength & Stability: Honeycomb keel structure and full welding reinforcement ensure excellent load-bearing capacity and rigidity, preventing mold expansion or deformation during concrete pouring, and ensuring accurate column dimensions with ±2mm flatness.
• Quick & Efficient Assembly: Equipped with innovative “buckle + pin” double-lock splicing system or Ztie™90 corner clamps, requiring only 3 bolts per 8ft corner; one worker can assemble 1㎡ in 10 minutes, 2.5 times more efficient than ordinary steel formwork.
• Adjustable & Versatile: Column sizes adjustable in small increments, compatible with various cross-sections, and universal panels can be used for both column and wall formwork, reducing the need for dedicated formwork systems.
• Superior Concrete Finish: Smooth formlining surface and leak-resistant bypass corners ensure fair-faced concrete quality, with no need for secondary plastering, reducing subsequent construction costs.
• Durable & Cost-Effective: Anti-rust surface treatment and high-quality materials enable 150-300+ reuse cycles, significantly reducing material waste and long-term construction costs compared to traditional formwork.
• Low Maintenance: Smooth steel surface and detachable components make cleaning and maintenance easy; dirt and concrete residues can be removed quickly with a damp cloth, extending service life.
• Eco-Friendly & Recyclable: Made of recyclable high-grade steel, minimizing environmental pollution; reusable design aligns with sustainable construction practices.

Applications

• Concrete column casting in high-rise residential buildings, office complexes, and hotels
• Infrastructure projects such as bridges, tunnels, and subway auxiliary projects
• Industrial facilities, factory workshops, and precast concrete column manufacturing
• Residential and commercial construction with repetitive column designs (e.g., apartment buildings)
• Narrow-space construction sites such as elevator shafts, corridors, and interior columns
• Large-scale projects requiring high concrete flatness and plumbness (e.g., landmark buildings)

Usage & Maintenance Notes

• Pre-use Inspection: Before application, carefully check each panel for steel frame deformation, formlining damage (peeling, cracks), loose screws, or rust spots. Inspect the splicing buckles and pins to ensure they are intact and flexible. Do not use damaged panels or accessories to avoid safety hazards and construction quality issues. All auxiliary lifting elements should be checked before each use and discarded if found to be faulty[1].
• Installation Guidelines: Only qualified personnel supervised by a competent person shall assemble and install the formwork[1]. During installation, strictly follow the project and manufacturer’s instructions, and ensure the support structure is stable and meets the designed load-bearing requirements. Level and stabilize the formwork properly according to terrain and weather conditions, and do not mount new panels until the previous ones are securely fixed[1][2]. Tighten all bolts and buckles to ensure no gaps between panels; seal gaps with waterproof tape to prevent slurry leakage. Avoid violent knocking during installation to protect the steel frame and formlining. When working close to high voltage power lines, shut off the power or take necessary protective measures as per applicable standards[1].
• Concrete Pouring Precautions: Monitor the pouring process closely to avoid uneven concrete pouring, which may cause local overpressure and mold expansion. Control the pouring speed and vibrate properly to prevent concrete segregation. Do not work on the formwork when wind speeds exceed 60 km/h or when there is ice or snow[1]. Under no circumstances shall people loiter beneath or in the path of elevated loads during pouring and hoisting[1].
• Demolding Requirements: Demolish the formwork only after the concrete has fully cured (compressive strength reaches at least 75% of the design strength) to avoid damaging the concrete surface. Demolish in the reverse order of installation, handle panels gently to avoid collision and deformation, and do not use sharp tools to pry the formwork, which may damage the formlining and steel frame[2].
• Cleaning & Maintenance: After demolding, promptly clean the surface of panels and accessories to remove concrete residues and dirt; use a soft brush or damp cloth, and avoid using corrosive cleaning agents that may damage the anti-rust coating. Check for loose screws, damaged buckles, or rust on the steel frame after cleaning; tighten loose screws, replace damaged accessories, and touch up rust spots with anti-rust paint to extend service life. For formlining panels, apply a layer of release agent after cleaning to protect the surface[2].
• Storage & Stacking: Store the formwork in a dry, well-ventilated indoor area away from direct sunlight, rain, and high humidity. Stack panels flat on level ground, elevate them from the ground with wooden blocks to prevent moisture absorption and rust, and control the stacking height within 1.2 meters to avoid deformation. Place frames on planks when stacking to avoid damage and facilitate organization[1][3]. Classify and store accessories (buckles, pins, bolts) in sealed boxes to prevent loss and rust. Avoid mixing with sharp objects or chemical reagents that may damage the formlining and steel surface[3].
• Transportation Care: Fix panels and accessories firmly during transportation to avoid collision, extrusion, or friction, which may damage the anti-rust coating and formlining. Cover with waterproof cloth to prevent rain erosion and sun exposure[3]. Choose appropriate transportation tools based on the size and weight of the formwork, and ensure the crane used is strong enough for handling and assembly[1][3]. Avoid dragging panels during loading and unloading to prevent surface scratches. If the crane operator cannot fully view the load trajectory, a signalman should guide the transport operations using predefined signals[1].
• Safety Precautions: Construction personnel must wear appropriate protective equipment (safety helmets, gloves, safety shoes, etc.) during installation, demolding, and handling. Establish strict safety management systems, and prohibit personnel without operation certificates from operating the formwork. Conduct pre-operation safety training and technical disclosure to ensure all operators understand the operation specifications and risk points[2].
