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.

According to Mr. Morandin, massive sheet metal snow guard failure is common in Northern Ontario. After tiring of “supplying customers with improper ice guard systems,” 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.
A trapezoidal roof profile has a ribbed trapezoidal-shape pattern across the panel. This means, it is a quadrilateral (or a four-sided shape – see Figure 1) that has just a single pair of parallel sides. Sometimes, trapezoidal roofs are mistakenly referred to as corrugated. This is a misnomer as the corrugated profile has a repeating wavy pattern across its surface.Trapezoidal rib roofs are popular with producers because the shape makes them very material-efficient (a high strength-to weight ratio). This makes for a very cost-effective profile. The shadows of the trapezoidal shapes offer clean lines whether installed vertically, diagonally, or horizontally. They also possess good structural characteristics and can carry design loads well (e.g. for snow and wind uplift). However, it is not considered as premium a profile as standing seam due to its attachment method.
This is the conclusion of our three-part series on S-5! Manufacturing. Part One featured the fortuitous meeting of Rob Haddock and Harry Carner, their partnership, and how they built their well-oiled manufacturing machine. Concerned about lack of control and a desire to always improve “the right way” to do things, these two men joined forces.
In our booth at IRE Nashville this year, we showcased our usual innovative selection of clamps and brackets. But we also featured a new product: the new and improved S-5-N clamp is an innovative attachment solution that cures your nail strip profile seating issues.
The clamp features an insert to facilitate installation and fit. it also fits seam profiles having a base of rib dimension < .82".
