Innovation Empowered, Rock-Solid Stability: HZM Leads the Revolution in Low-Voltage Switchgear Frame Profiles​

Introduction
In complex industrial environments, low-voltage switchgear is the heart of power distribution systems, demanding exceptional performance, stability, and flexibility. Traditional welded frames or open-profile structures often struggle with design limitations, complex manufacturing, and insufficient strength. HZM, attuned to market needs, drives continuous independent technological innovation with its premium closed-section frame profile solutions – the NineFold™ and SixteenFold™ profiles. This redefines the manufacturing standards and quality benchmarks for low-voltage switchgear enclosures.

The Evolution of Frame Structures & Core Challenges
Low-voltage switchgear is highly customized, featuring diverse configurations and a wide array of components. The ideal frame must deliver:

1. Unparalleled Strength & Rigidity: Withstand operational electromechanical stresses, vibration (including seismic events, shipboard rolling), ensuring long-term reliability.

2. High Flexibility & Modularity: Support diverse component layouts, enable easy adjustments, and allow for rapid installation and maintenance.

3. Efficient Production & Cost Optimization: Simplify design, manufacturing, and assembly processes, reducing overall costs and error rates.

Early welded structures were cumbersome. While open C-section profiles (standard or reinforced) or copycat 8MF profiles offered some assembly advantages, they fell short in structural strength, space efficiency, and resilience in demanding environments.

HZM's Solution: NineFold™ & SixteenFold™ Closed Profiles

Leveraging deep industry insight, HZM pioneered the NineFold™ and SixteenFold™ profile technologies, elevating frame design to new heights.

1. Core Technology: Closed-Section Pillar & Beam Structure

• Both NineFold™ and SixteenFold™ profiles embody a closed-section design philosophy. Compared to open C-profiles, the closed cross-section significantly enhances bending strength (load-bearing capacity up to 49,000 newtons) and torsional stiffness, delivering "spine-like" structural stability.

• The "Fold" Significance: Named for the precise number of bends during roll forming (nine or sixteen). Each bend not only shapes the closed profile but intrinsically creates multiple integrated reinforcement ribs. This dramatically increases material efficiency, achieving superior strength with equivalent material usage.

2. SixteenFold™ Profile: The Flagship Strength Standard

• Superior Load-Bearing & Support: The significant number of bends creates a larger effective cross-sectional area and denser reinforcement, endowing SixteenFold™ with industry-leading load capacity and resistance to deformation.

• Outstanding Environmental Resilience: Its tolerance for extreme conditions (severe vibration, rolling environments, high seismic requirements) makes it the ideal choice for critical high-end applications, providing "granite-grade" protection.

3. NineFold™ Profile: The Master of Performance-Cost Balance

• Optimized Space Utilization: Its refined cross-section occupies less space, offering greater freedom for internal component arrangement.

• High Cost-Effectiveness: Utilizing mature roll-forming processes, NineFold™ delivers exceptional strength (significantly surpassing traditional C-profiles) and installation flexibility at a highly competitive cost.

• Proven & Widely Adopted: A mature and reliable solution for network racks, control panels, and distribution cabinets, earning strong user trust.

4. Advanced Manufacturing: Precision Roll Forming
   HZM profiles are manufactured using high-precision roll forming technology:

• High Precision & Efficiency: Cold-rolled steel strip undergoes continuous bending through multi-pass, precisely shaped rollers, achieving dimensional accuracy and shape consistency in a single pass – vastly outperforming piece-by-piece bending.

• Guaranteed Performance: Eliminates heat-affected zones from welding, preserving material integrity and ensuring uniform quality.

• Future Potential: Integration with servo-control enables future flexible variable cross-section (FVS) production, unlocking new possibilities for customized cabinet design.

Core Value & User Benefits of HZM Profiles

1. Unmatched Stability, Guaranteed Operation: Ultra-high strength and resistance to torsion/vibration meet the most stringent environmental and safety standards, safeguarding critical power system integrity.

2. Smart Design, Flexible Configuration: Abundant mounting surfaces cater comprehensively to all electrical component needs. High-precision, modular design enables highly efficient scheme adaptation, component placement, and assembly.

3. Cost Reduction & Efficiency Gains: Simplifies design workflows (reducing customization effort), optimizes manufacturing and assembly (minimizing errors and rework), significantly boosting productivity and overall cost-effectiveness.

4. Elevated Quality, Enhanced Brand: Embodies advanced technology from the foundational frame upwards, imparting superior intrinsic quality and a professional image to switchgear products, positioning them as the quality choice for premium electrical and control equipment enclosures.

5. Proprietary Design, Technological Edge: HZM's NineFold™ and SixteenFold™ profiles are fully independently designed core technologies (patent-pending), uniquely engineered to optimize equipment functionality and performance, providing a distinct competitive advantage.
