Introduction: The Critical Need for Peripheral Protection in Skyscrapers
As global urbanization accelerates, super high-rise buildings exceeding 150 meters have become a standard feature of modern metropolitan skylines. However, with every additional floor, construction safety risks increase exponentially. Risks such as falling objects, personnel falls, and extreme weather conditions impose unprecedented demands on construction site safety.
Against this backdrop, the architectural protection screen emerged. A protection screen is a novel safety device attached to a building's structural elements—such as floor slabs, beams, or walls—and hoisted into place using hydraulic systems or tower cranes. Unlike traditional modular scaffolding, it functions as an integrated, fully enclosed safety barrier capable of climbing upward in tandem with the main building structure.
GETO's protection screens are specifically tailored for high-rise, super high-rise, and prefabricated buildings. By creating a fully enclosed working environment, they fundamentally eliminate the risk of falling objects, provide workers with a sense of security as stable as standing on solid ground, and protect ground-level pedestrians and surrounding facilities.
Classification & Customization: Residential vs. Commercial Solutions
Super high-rise buildings are not all the same. Residential towers and commercial office buildings differ significantly in facade complexity and work frequency. GETO's protection screens address this through classified, customized designs that precisely match different building types.
Residential Version
Residential building facades typically feature numerous walls, balconies, air conditioner ledges, bay windows, and other projections, with frequent exterior work such as plastering, tiling, and window installation. To address these characteristics, GETO's residential protection screen provides more platform levels (typically 4-5 working platforms), ensuring safe standing and working space for workers at different heights. The multi-platform design allows rebar tying, formwork reinforcement, concrete pouring, and exterior finishing to proceed simultaneously on different levels without interference.
Commercial Version
Office buildings, hotels, and other public buildings typically feature glass curtain walls or dry-hanging stone facades with fewer walls. Exterior work is relatively concentrated after the main structure is complete. For this scenario, GETO's commercial protection screen optimizes the number of platform levels (typically 3-4) while maintaining safety, focusing on perimeter protection and curtain wall access, avoiding unnecessary platform redundancy to reduce system weight and cost.
General Technical Specifications
Regardless of version, GETO protection screens provide a protection height of typically 8-9 meters, fully covering 2-3 standard residential floor heights (2.8-3.2 meters). This ensures that the working face remains under fully enclosed protection during climbing intervals.
Core Engineering Advantages: Safety, Stability, and Durability
GETO's protection screens deliver competitive advantages through three core engineering strengths: extreme safety design, exceptional wind resistance, and decade-long corrosion durability.
High Safety: Independent Anti-Fall Devices and Fully Steel-Hardened Enclosure
GETO protection screens incorporate multiple redundant safety designs:
- Independent Anti-Fall and Anti-Overturning Devices: The system is equipped with independent mechanical anti-fall devices that do not rely on hydraulic or electrical systems. Even in extreme cases of power failure, they automatically lock to prevent accidental falling or overturning of the protection screen. This design minimizes safety risks caused by operational errors or equipment failure.
- Fully Steel-Hardened, Fully Enclosed Design: All components of the protection screen—including guide rails, corner connectors, platform decks, and protective mesh panels—are manufactured from high-strength steel, forming a completely enclosed containment system. Guide rails and corners feature dedicated sealing components to prevent any materials or tools from falling through gaps. The fully enclosed design also provides workers with shelter from wind and rain, reducing weather-related downtime.
Extreme Weather Adaptability: Wind Resistance, Fire Protection, and Lightning Protection
At altitudes above 100 meters, wind forces are significantly greater than at ground level, imposing extremely high demands on the protection screen's wind resistance.
- Strong Wind Resistance: GETO protection screens withstand maximum Level 9 wind loads (approximately 83.5 km/h), operating safely without additional reinforcement under such wind pressures. When forecast winds exceed safety thresholds, the system issues alerts and recommends suspending climbing operations.
- Fire and Lightning Protection: The fully steel-hardened structure inherently provides excellent fire resistance. Additionally, the system incorporates dedicated lightning protection grounding devices that safely conduct lightning currents into the building's main lightning protection system, preventing injury to personnel and damage to equipment.
Material Longevity: C5 Corrosion Resistance and 10-Year Maintenance Cycle
Protection screens must endure years of repeated use while exposed to rain, sun, coastal salt spray, and other harsh environments. GETO protection screens feature hot-dip galvanizing surface treatment, providing uniform, strongly adherent zinc coating.
- C5 Corrosion Level: This treatment achieves C5 corrosion resistance level —the highest corrosion classification under international standard ISO 12944 for high-humidity and high-salt environments (such as coastal areas and industrial pollution zones).
- 10-Year Maintenance Cycle: Thanks to superior corrosion resistance, GETO protection screens have a design initial maintenance cycle of ≥ 10 years, meaning under normal use conditions, almost no major rust maintenance is required for the first decade, significantly reducing lifecycle costs.
Operational Efficiency: Hydraulic Power and Modularity
Beyond safety and durability, GETO protection screens achieve breakthroughs in construction efficiency through hydraulic drive systems and highly modular design, helping contractors significantly shorten project timelines and reduce costs.
Hydraulic Drive System: Smooth, Fast, and Crane-Free (H3)
GETO protection screens feature a "1 to 4" hydraulic pump station configuration—one hydraulic pump station simultaneously drives four climbing units, ensuring horizontal leveling and synchronization during the climbing process.
- Smooth Lifting: The hydraulic system provides uniform, controllable lifting force, avoiding the shocks and swaying common with mechanical lifting.
- No Additional Lifting Equipment Required: The entire climbing process requires no tower crane time, freeing cranes for essential material handling such as rebar and concrete buckets.
- Fast Climbing: Lifting a standard floor height (approximately 3 meters) takes only about 10 minutes. This means that shortly after concrete pouring is complete, the protection screen can climb to the next level, ready for the next construction cycle.
High Standardization: Over 95% Commonality Rate
Traditional climbing frames have numerous component types, leading tochaotic on-site management, misplacement, and loss. GETO protection screens simplify design, controlling main component types to no more than 10.
- Commonality Rate Exceeds 95%: Extremely high component commonality means protection screen components can be interchanged between different projects and different towers.
- Reduced Management Costs: Warehouse stocking, on-site counting, and turnover refurbishment become exceptionally simple.
- Reduced Installation Errors: Workers need only familiarize themselves with a few component types to complete assembly, lowering training costs and installation error rates.
Lightweight Design
Compared to traditional steel climbing frames, GETO protection screens achieve significant lightweighting through optimized cross-section design and reduced redundant components.
- Lower dead weight reduces additional loads on building structures.
- Lightweight components make disassembly, transport, and transfer more convenient, reducing reliance on large lifting equipment, thereby lowering labor and equipment rental costs.
Integration Synergy: The "1+N" Integrated Solution
In modern super high-rise construction, protection screens do not operate in isolation. GETO integrates them as a core component of the "1+N" Integrated Solution, creating synergy with formwork and climbing systems.
Aluminum Formwork Synergy: Fully Enclosed Production Line
GETO protection screens achieve seamless integration with GETO's flagship aluminum formwork system. While the protection screen forms a fully enclosed safety barrier around the building perimeter, the internal aluminum formwork efficiently performs wall, column, and slab pouring.
- The protection screens and aluminum formwork share a common set of positioning benchmarks and lifting sequences, thereby establishing a fully enclosed, integrated assembly line.
- Workers operate within a safe, windproof, and rainproof environment—shielded from adverse weather conditions—resulting in more consistent and stable construction quality.
Perimeter protection and internal formwork climb simultaneously, avoiding the mutual constraints of lagging perimeter protection or waiting internal formwork found in traditional construction.
Intelligent Monitoring: Real-Time Climbing Safety Assurance
GETO protection screens are equipped with an intelligent synchronized control system that digitally monitors the entire climbing process:
- Real-Time Load Monitoring: Sensors continuously monitor loads at each climbing unit. If abnormal load imbalance is detected, the system immediately alerts operators to adjust.
- Synchronized Control: The system ensures multi-point synchronized lifting, preventing distortion or jamming caused by asynchronous climbing.
- Data Logging and Traceability: Load data, operating time, and anomaly alerts for each ascent are recorded and can be utilized for safety audits and continuous improvement.
Economic Analysis: Lifecycle Cost and Return on Investment
For contractors and developers, selecting a protection screen is not only a safety decision but also an economic one. GETO protection screens deliver significant cost savings and return on investment throughout their lifecycle through multiple design optimizations.
Direct Cost Savings: Tower Crane Hours and Labor Input
Traditional climbing frame systems often require tower crane assistance during lifting, preventing the crane from simultaneously handling core materials such as rebar, formwork, and concrete, creating construction bottlenecks.
- Zero Tower Crane Occupation: GETO protection screens use hydraulic drive, requiring no tower crane involvement throughout the process. For a typical 30-story super high-rise project, saving approximately 2 tower crane hours per floor accumulates to 60 hours total, directly reducing equipment rental costs.
- Labor Efficiency Improvement: With component standardization exceeding 95%, workers are no longer required to sort through and select from a multitude of complex parts, resulting in an assembly efficiency increase of approximately 30%. Furthermore, the lightweight design reduces the weight handled per lift, thereby minimizing physical exertion for workers and lowering the required headcount.
Indirect Cost Savings: Maintenance and Turnover
- 10 Years Without Major Maintenance: C5 level hot-dip galvanizing enables the protection screen to maintain a first maintenance cycle of over 10 years even in harsh coastal environments. screens save considerable corrosion maintenance costs over their lifecycle.
- High Turnover Efficiency: Standardized design allows protection screen components to flow quickly between different projects and towers. When one project completes, components can bedirectly deployed the next project without complex sorting, reducing idle time and improving asset utilization.
Safety Cost Avoidance: The Economic Value of Zero Accidents
The direct costs (medical treatment, compensation, fines) and indirect costs (schedule delays, reputation damage, increased insurance premiums) of falling object or personnel fall accidents can reach millions of dollars. While no system can guarantee zero risk, the fully enclosed design and independent anti-fall devices of GETO protection screens significantly reduce the likelihood of accidents at height. Even one moderate-to-severe incident avoided can justify the investment many times over.
Payback Period
Considering direct cost savings (tower crane, labor), indirect cost savings (maintenance, turnover), and safety cost avoidance, GETO protection screens typically achieve a payback period of 1-2 projects (approximately 2-3 years) . Beyond this period, the protection screen can continue serving subsequent projects, generating sustained net returns.
