Strut Channel in Solar Mounting Systems
As the global photovoltaic industry continues to expand, the demand for durable and versatile structural components has grown significantly. Among the essential elements used in solar mounting structures, the Strut Channel plays a critical role in providing strength, flexibility, and efficient assembly.
For manufacturers seeking to produce high-quality solar support components, investing in a professional Strut Channel Roll Forming Machine is the key to achieving precision, productivity, and long-term competitiveness.
This article explains what strut channels are, their materials and specifications, manufacturing processes, and how XC (XiongChang) delivers customized roll forming solutions for localized solar structure production.
What is a Strut Channel in Solar Mounting Systems?
A Strut Channel is a standardized cold-formed steel structural profile widely used in solar mounting systems, construction support systems, cable management, and industrial framing.
In photovoltaic applications, strut channels serve as structural members that support and connect solar mounting assemblies.
They are commonly used as:
- Support rails
- Cross beams
- Secondary structural supports
- Adjustable mounting members
- Connector framework for solar panel systems
The popularity of strut channels in solar mounting structure systems comes from their:
- High structural strength
- Easy modular installation
- Flexible hole-slot configurations
- Excellent corrosion resistance
- Cost-effective production
Because of these advantages, Solar Strut Channel has become one of the most widely used profiles in rooftop and ground-mounted solar projects.
Common Materials Used for Solar Strut Channels
The material selection directly determines the strength, durability, and corrosion resistance of the final product.
1. Hot-Dip Galvanized Steel
Hot-Dip Galvanized Steel is the most common material for solar strut channels.
Advantages:
- Excellent corrosion protection
- Strong structural performance
- Cost-effective for outdoor use
It is ideal for large-scale photovoltaic support systems.
2. Pre-Galvanized Steel
This material is commonly used for standard environments.
Benefits:
- Smooth surface finish
- Lower production cost
- Suitable for moderate exposure conditions
3. Zn-Al-Mg Coated Steel
Also known as:
ZAM Steel
This advanced material is increasingly preferred for modern solar mounting structure manufacturing.
Advantages:
- Superior corrosion resistance
- Better cut-edge protection
- Longer service life
- Lower maintenance requirements
4. High-Strength Structural Steel
Used when projects require greater load-bearing performance.
Typical grades include:
- Q235
- Q355
- S350GD
- S550GD
These materials ensure the structural stability of solar support systems under wind and snow loads.
Typical Thickness of Strut Channel Profiles
The thickness of a solar strut channel depends on project design requirements and environmental load conditions.
Common thickness range:
1.5mm – 4.0mm
Typical applications:
1.5mm – 2.0mm
Suitable for:
- Residential rooftop systems
- Light-duty support structures
2.0mm – 2.5mm
Suitable for:
- Commercial rooftop projects
- Medium-load applications
2.5mm – 4.0mm
Suitable for:
- Ground-mounted solar farms
- Utility-scale PV installations
- Heavy wind/snow load regions
A high-performance Strut Channel Roll Forming Machine must support multiple thickness ranges with stable forming quality.
Standard Sizes of Strut Channels
Several standard dimensions dominate the global market.
Common Sizes
41 × 21 mm
Used for lightweight support applications.
41 × 41 mm
The most widely used standard size.
Popular for:
- Rooftop solar systems
- Modular support framing
41 × 62 mm
Provides increased structural strength.
52 × 52 mm
Suitable for heavy-duty solar mounting applications.
Unistrut-Compatible Profiles
Many projects require compatibility with international installation systems.
Customized sizes can also be developed according to customer drawings.
This is why customized Strut Channel Roll Forming Machines are highly valued by manufacturers targeting local market requirements.
How Are Strut Channels Manufactured?
The modern production of Solar Strut Channel relies on advanced cold roll forming technology.
The typical manufacturing process includes:
1. Coil Loading
Galvanized steel coils are loaded onto a Hydraulic Decoiler.
2. Feeding and Leveling
The material is flattened for consistent feeding.
This ensures:
- Better profile straightness
- Improved punching accuracy
3. Servo Punching
A servo punching system creates:
- Slotted holes
- Mounting holes
- Connection openings
- Drainage holes
This step is essential for modular assembly.
4. Roll Forming
The strip passes through multiple forming stations.
The steel is gradually shaped into the required Strut Channel profile.
Typical forming stations:
18–24 passes
This guarantees:
- Dimensional accuracy
- Smooth surface quality
- Structural consistency
5. Hydraulic Cutting
Profiles are cut to programmed lengths.
Features include:
- High cutting precision
- Clean edge quality
- Automatic operation
