Square Steel Tube for Solar Mounting

Overview:

Square steel tubes serve as the structural backbone for many solar mounting systems, particularly in ground-mounted arrays, solar carports, and large-scale utility projects. They are chosen for their high load-bearing capacity, torsional rigidity, and ability to withstand significant wind and snow loads.

Key Specifications for this Square Steel Tube:

We are good partener with EPCs, distributors,and installers, these are the critical details you will require:

1. Dimensions (Profile Size):

Common sizes include 40×40mm (often used for smaller rails or purlins), 50×50mm, 60×60mm, 80×80mm,100×100mm,120×120mm, 140×140mm…… (for main support posts).

2. Wall Thickness:

Typically ranges from 1.8mm to 3.0mm depending on the structural load requirements.

3. Material & Coating (Anti-Corrosion):

ZAM (Zinc-Aluminum-Magnesium): Increasingly popular for superior corrosion resistance in harsh or coastal environments.

4. Length:

Our Standard lengths are usually 6 meters, but our factory can provide custom cut-to-length services to reduce onsite waste.

Typical Applications

• Ground-Mount Systems:Used as vertical posts driven into the ground or attached to ground screws.
• Solar Carports:Used for the main frame and roof purlins to support the weight of the panels and the structure itself.
• Industrial Rooftop Racking:Used when the roof structure requires a more robust, heavy-duty support system than standard aluminum rails.

Why it’s used

• Good strength-to-weightratio
• Simple fabrication for drilling, welding, and brackets
• Works with standard racking components (brackets, clamps, end caps, connectors)

Sales & Quotation Advice

To provide a professional quote that helps you close the deal, please kind let us know the informations as the following:

• Design/Structural Drawings:It would be perfect if you have a BOQ (Bill of Quantities) or structural design.
• Load Requirements:Are there specific wind or snow load standards (e.g., Eurocode, AS/NZS) the steel must meet?
• Hole Punching:Do you require pre-punched holes for assembly?
• Packaging:Do you need bundles, or specific crating for international shipping?
