Mounting Structure Products
Three core components — the GI backbone, the edge clamp, and the inter-panel clamp — that together hold your entire solar array safely for 25 years.
Hot Dip GI Box Pipe
Structural backbone of every rooftop and ground-mount system
Hot-dip galvanized steel box pipes form the primary load-bearing framework for solar panel arrays. The hot-dip process drives zinc deep into the steel surface — creating a metallurgical bond that outlasts paint or electroplating by decades. Each pipe is engineered to carry the combined weight of panels, wind loads, and snow loads without deflection.
Key Features
- Hot-dip galvanized — not spray-painted or electroplated
- Uniform zinc coating inside and outside the pipe
- 25-year structural warranty against corrosion
- Available in standard and custom lengths
- Suitable for coastal, industrial, and agricultural environments
Specifications
End Clamp
Secure outer-row panels to the mounting rail with precision
Aluminum end clamps grip the edge panels of each row, preventing lateral movement caused by wind uplift or vibration. Manufactured from extruded aluminum alloy, they are lightweight yet strong enough to hold panels firmly across the full 25-year system life. Captive bolt design allows installation without dropping hardware onto the roof below.
Key Features
- Aluminum construction — zero corrosion risk
- Fits panel frame heights from 30 mm to 50 mm
- Captive bolt for single-hand installation
- Stainless steel hardware included
- Compatible with all standard aluminum mounting rails
Specifications
Mid Clamp
Connect panel-to-panel on rails with a single fastener
Mid clamps sit between adjacent panels in a row, holding both frames simultaneously with one central bolt. This halves the fastener count compared to individual end clamps on inner positions, speeding installation and reducing labor cost. The anodized aluminum body electrically bonds neighboring frames — eliminating the need for separate bonding jumpers on most designs.
Key Features
- Bonds two panels with a single fastener
- Built-in frame-to-frame electrical bonding
- Reduces installation time on large arrays
- Adjustable to accommodate varying frame heights
- Compatible with all standard aluminum rail systems

Rooftop vs Ground-Mount Structures
The same hot-dip GI pipe serves both installation types. The engineering configuration adapts to your site — not the other way around.
Rooftop Mounting
- Fixed-tilt or flat-roof ballasted systems
- Aluminum sub-rails attached to GI main pipe
- Low wind-load profile for RCC and sheet metal roofs
- Panel tilt: 10°–15° for flat roofs, flush for sloped
- Suitable for 1kW home systems to 500kW+ commercial arrays
Ground Mount Structures
- Driven pile or concrete footing foundation
- Single-axis and fixed-tilt configurations available
- Heavier gauge GI pipe for ground-level wind exposure
- Ideal for open land, agricultural plots, and solar parks
- Engineered drawings available for DISCOM submissions
Why Hot-Dip GI Is the Only Acceptable Standard
Solar panels last 25 years. Your mounting structure must too. Here is why hot-dip galvanization is not a premium option — it is the baseline requirement for any serious installation.
Metallurgical Bond — Not Just a Coating
Hot-dip galvanizing creates zinc-iron alloy layers that are part of the steel itself. Unlike spray paint or powder coating, this bond cannot flake, peel, or be scratched off during installation. The result is corrosion protection that matches the life of the structure.
Self-Healing in Damaged Areas
Even if a corner gets nicked during transport, zinc migrates to protect the exposed steel through cathodic action. No touch-up paint, no rust creep. The galvanic protection continues working even on small scratches — unlike painted or coated alternatives.
Proven 25-Year Lifespan
A 25-year structural warranty is only credible if the material can back it up. Hot-dip GI structures installed in coastal Gujarat — one of India's most corrosive environments — show less than 5% material loss after 20 years in field studies. Cheaper alternatives fail visibly within 3–5 years.
No Ongoing Maintenance
Solar structures are typically unreachable without scaffolding once panels are installed. HDG structures need zero maintenance painting or re-coating over their operational life — unlike MS painted structures that require re-painting every 3–5 years to maintain structural integrity.
