Micro rails are a relatively common way of attaching a solar array to exposed-fastened metal roofs. This method uses small rail sections in specific areas as needed along the roof – reducing the total length of rails. They have benefits which make them desirable to contactors and installers alike. They provide material and shipping cost savings to the customer when compared to rail systems. In addition, they are small, which allows them to be handled easily onto roofs. They are forgiving with spacing allowing for minimal or customizable walk spaces. Additionally, micro rails can be installed with just a couple of fasteners - potentially cutting installation times compared to rails.
Massive snow accumulation on a roof creates the potential for an unpredictable avalanche-like effect. Metal is a great choice for your rooftop. It has a long life expectancy and can stand up to the harshest conditions. It does have a low coefficient of friction though–meaning things (including snow) don’t stick to it very well. But the notion that snow is intended to slide off a metal roof is misguided and can be dangerous.
Being the experts on all things metal roof and metal roof attachments, we are often asked by solar developers and installers what is the most cost-effective way to install solar panels on metal roofs. There are multiple options when putting solar on a metal roof, and each come with pros and cons that can impact installation costs and lifetime performance.
Did you know that your roof already comes with free rails? You can mount PV directly to the roof panels themselves - using the “direct-attach” method. Whether you are dealing with standing seam or ribbed, face-fastened panels, these metal roofs have one thing in common: They all have built-in rails. (See image to the left: Standing seam metal roofs have rails (the seams) built right in ready for direct attachment of solar panels.)
When it comes to sharing solar array costs, companies often shy away and dance around the question. They usually focus on the customization angle – telling you that prices vary, and that this is what makes estimation difficult.
Now, of course costs vary, because no two projects are the same but whether you are an installer, contractor, or a homeowner, you share two common questions:
How much is this going to cost me and how long is it going to take?
Carbon steel is inherently susceptible to corrosion, which means it must be protected by some other metallic coating that is less corrosive. Carbon steel sheet is called “galvanized” when coated with a thin layer of pure zinc.
This coating provides two types of corrosion protection for the steel: “barrier protection” (sealing the surface from air and water) and “sacrificial protection” or “galvanic” protection—especially at scratches and cut edges.
This is an electrolytic process whereby the base metal is protected, but at the expense of the coating. The zinc “sacrifices” itself to protect the underlying layer of steel.

The best test of our products is real-life application. This S-5! success story came from Guido Morandin of Work Monster, Inc. in Canada. The Work Monster project features two S-5! products: VersaBracket™ and ColorGard snow retention.
Massive sheet metal snow guard failure is a common occurrence in Northern Ontario. After tiring of “supplying customers with improper ice guard systems,” he needed a real solution that would help mitigate this dangerous phenomenon. He discovered S-5!
Swarf are the shavings of metal debris produced during machining. These chips or filings can also be produced during woodworking, grinding and other manufacturing processes. Metal, wood, plastic and stone can all produce this debris which is often called “swarf”.
At S-5 Manufacturing, the small chips and shavings created during the cutting, milling or drilling of stainless steel, aluminum and brass parts could be called “swarf”, but we commonly call them “saw chips” or “turnings” and produce tons of them each month. In that case, they are automatically collected at their source by special equipment and recycled regularly. We recycle approximately 40 Cu. Yd. or 14,450 lb. of aluminum chips every month. That amounts to over 7 tons per month of “swarf”. There are additional shavings produced when machining our brass and stainless steel clamps and brackets, but that volume is much lower than the aluminum.

COR-TEN® is a special steel alloy that has a weathered, rusty-orange look. The material, also referred to as corten or CorTen, was developed to eliminate the need for painting the metal. Cor-Ten forms a stable rust-like appearance after being exposed several years to weather.
U.S. Steel owns the trademark on Cor-Ten. This steel alloy is encouraged to rust – and form a dark brown oxidation. This rust forms a protective coating over the surface that slows further corrosion.
