The heavy-duty rooftop support with a patent to prove it

By Green Link, Inc. 

After years of rigorous testing and refinement, the MetalHead support system sets a new benchmark for durability and design excellence in rooftop applications. 

When you're dealing with heavy pipes, duct systems and HVAC/R equipment, you need more than just a support system — you need strength, durability and reliability you can count on for years to come. That’s why Green Link, Inc. has spent the last few years tirelessly testing, modifying and improving the MetalHead triangular support, and why we are excited to announce that, as of September 9, 2025, we have officially been awarded the design patent for this innovative support solution. 

Why choose Green Link MetalHead? 

1 – Unmatched strength & durability 

The Green Link MetalHead isn’t just another rooftop support – it's an engineering marvel. With 100-mil aluminum walls and a 10,000 pound vertical compression threshold (more than 20x the weight limit of a standard rubber-based block), the MetalHead is built to handle the toughest loads, no matter how demanding your application. Its heavy-duty triangular design provides a 50 square inch base for unbeatable stability and weight distribution. 

2 – Protect your roof & equipment 

Unlike traditional supports, the (optional) black PEF pad provides an additional layer of protection, preventing abrasion and damage to your roof membranes, whether it's PVC, TPO, EPDM or asphalt-based roofing. This extra protection ensures your system stays intact and your roof is protected, preserving its integrity for years to come. 

3 – Easy installation & customization 

The MetalHead is designed for quick and easy installation – weighing in at just 2 pounds, the MetalHead has a built-in strut channel compatible with all standard strut hardware and accessories. The system’s flexibility allows you to tailor it to your project, whether it calls for a single support point or a large installation.  

4 – Long-term value & sustainability 

The Green Link MetalHead is not just a short-term fix; it's an investment in your infrastructure. Built for reuse and recycling, coupled with its resistance to oxidation, salt spray and mild acids, this system offers exceptional long-term value, saving you time and money on replacements. Plus, it’s made in the USA and backed by a 20-year limited warranty, ensuring you have peace of mind for decades. 

5 – Simplified installation with Snap-N-Strut  

Forget the hassle of using wrenches or impact guns! With Snap-N-Strut, installation is as simple as twisting the unit directly into the MetalHead strut channel, snapping the pipe into place and clipping the Snap-N-Strut shut. These reliable and secure supports are ideal for pipes ranging from ¼”OD to 4”OD.
