Looking For the Lowest Price Metal Roof Systems – Be Careful What You Wish For

How often are your decisions driven exclusively by price and nothing else?  If the answer is always, you may want to consider your reasoning moving forward. A metal roof system is more than just a temporary cover for a commercial building or home.  The quality of the material, the quality of the paint that covers that metal roof and the support that you get from the manufacturer covering both the material and the paint finish is critical.

Portable Rollforming Brings Back the Craftsmanship

Before the turn of the 20th Century, standing seam metal roofing material was measured, cut, roll formed and installed onsite by artisans used to working with a variety of different metals including copper, terne-coated metal and tin-coated steel. The hand crafted, custom made work of artisans gave way to mechanized production during World War II when factory “roll forming” technology was invented. This approach was the first departure from a one-at-a-time manufacturing mentality. Progressive roll tooling in a factory could produce a finished profile in a continuous process rather than step-by-step cutting and bending. Continue reading

Caution to Contractors: Bending Techniques for Aluminum Differ from Steel

When metal roofing manufacturers first introduced aluminum material for standing seam roofing, much of the aluminum produced was .032 thickness.

However, over the years the building products industry has been gravitating to thicker roofing and trim material, especially in aluminum. And, Dade County Florida enacted new wind uplift rules for metal roofing that required the use of .040 aluminum for roofs and .050 thickness for trim material to meet the rule requirements.

Consequently, contractors were transitioning from the use of .018 to .024 thick Galvalume or Hot Dipped Galvanized steel roofing and trim products to .032 to .050 thick Aluminum. Many contractors assumed aluminum bent the same as steel and therefore thought little adjustment was needed to make crisp bends on aluminum as they had done with steel. This resulted in some contractors bending these heavier aluminum products beyond their tensile strength limits resulting in cracking of the metal and paint as well as leaving a silver look from the crazed aluminum under the paint.

Routine Maintenance Adds Life to Your Gutter Machine

Regular preventive maintenance is probably the single thing you can do as a gutter rollforming machine owner and operator to keep your business humming and save money on repairs in the future.

Anyone who’s ever had a gutter machine out of service and lost money on downtime and repairs will tell you: Don’t ignore preventive maintenance.Portable roll forming machine producing metal roofing panel

The basics will keep your rollformer healthy and give you a chance to catch anything serious before it becomes a major problem. It all depends on you. Every new machine sold in the marketplace comes with an operating and maintenance manual. We have several gutter machines in our repair shop right now ranging from one that is nine months old and looks like it’s been in the field 10 years and another that is 10 years old and looks as good as the day it first saw service.

Meeting Standards for Metal Wall Panels: An Important Consideration in Building Design

There are thousands of building materials and products globally and virtually all of those used in a manufactured environment are subject to some form of testing and standards.

There are a host of international standards organizations that set standards for and test all kinds of products. There are de facto standards which means they are followed by informal convention or dominant usage, de jure standards which are part of legally binding contracts, laws or regulations and voluntary standards which are published and available for people to consider for use.

Picture of metal wall panels used in construction.The people who use an item (architects, engineers, contractors, etc.) or specify it (building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly.

By the end of the 19th century, differences in standards between companies, was making trade increasingly difficult and strained. Hence the establishment of professionally supported standards organizations.  Progress was nevertheless slow. Suppliers in many industries including construction objected to standard material specifications and testing procedures because they feared that strict quality controls would make customers more inclined to reject items and default on contracts.

There was plenty of back and forth on the issue but the demand by material end users like the powerful railroad industry finally led to the formation of the American Society of Testing and Materials in 1898.

To this day, the ASTM remains one of the key standards organizations in the world. And in the area of wall panel, it provides some of the key standards for materials used in building design and construction. Continue reading

Steel and Aluminum—Two Great Metal Roofing Materials, Each Have Their “Strengths”

If you are a designer or builder considering a standing seam metal roof you may be asking the question what is the difference between aluminum and steel as a choice for the metal roof.

Commercial and residential metal roofing is primarily made of steel or aluminum. Both products are initially produced in giant rolls at a mill. All steel roofing has a protective barrier on both sides of the sheet called a metallic coating which protects against rusting. This is underneath and separate from any paint which imparts color to the product. There are two types of metallic coatings used: galvanized, which uses 100% Zinc in various thicknesses depending upon the product usage, and Galvalume, a mixture of aluminum and zinc. These metallic coatings “sacrifice” themselves to protect the iron in steel from oxidation when exposed to air and moisture. Zinc is a more “active” metal than iron so it oxidizes first and forms a protective barrier — zinc oxide, before the iron in the steel can become Ferric Oxide (rust). When zinc is combined with aluminum to form Galvalume there is even more protection in most circumstances.Metal roofing coil in various colors.

Steel residential roofing is made in thicknesses designated by gauge and is generally 24 to 26 gauge, with the higher gauge being thinner than the lower. These gauges are appropriate since most residential metal roofing applications are over a solid substrate. Aluminum residential metal roofing is designated by decimal thickness and ranges from .023 to .040 thickness.

Steel and aluminum both perform well as a metal roofing material. However, aluminum roofing, depending upon the exact product chosen, can run up to 20 percent higher in price compared to steel roofing. Continue reading

What Contractors Should Know When Buying Metal Roofing Coil

Contractors looking for a good deal on galvanized steel and aluminum roofing coil should always be careful—if it looks too good to be true then it probably isn’t.

There are some tools and “rules of thumb” for them to be sure they’re at least getting what they paid for.

Contractors order metal roofing coil by the square foot and most, in turn, charge their clients the same way.

So the number of square feet a coil is going to yield will dictate how much they are going to pay and how much they are going to earn.

There are a few unknowns in the process. Let’s use 24 gauge steel coil as our example. One coil of 24 gauge material can be different from another. That’s because industry standards permit “tolerances” in what constitutes a 24 gauge thickness. For example, we’ve know of one widely used “standard” that allows the thickness of 24 gauge galvanized steel to be anywhere from .0236 to .0316 inches thick. We know another one that only allows it to be from .0236 to .0296. A lot of contractors know this and realize that the yield of a coil may differ to some degree based on those tolerances. The only way to figure how many square feet the coil will accurately yield is to use a micrometer to measure the thickness of the material. And only a handful of large contractors and distributors have micrometers. Continue reading

Design the Best Standing Seam Metal Roof for Your Projects in Asia, Make Sure the Coil and Roll Former are Western Made

The United States imported more than four times as many goods from China as we exported there last year.

But our trade imbalance with China has gone the other way when it comes to professional services. Professional services, including architecture, constitute roughly a third of America’s exports, according to Architect Magazine, which notes many major American architecture firms now have offices in the largest Chinese cities, such as Beijing and Shanghai, as well as second-tier cities like Tianjin.Metal Roofing Roll Forming Machine

However, if you’re one of those design firms and you’re specifying metal roofs in Asia, beware! The quality of metal roofing coil and the roll forming machines made there are often greatly inferior to coil and machines made in the U.S. and in Western Europe.

Our in-house machine expert, Mike Gorski, has had the opportunity to visit other continents and see the different roll forming equipment made in places like China, the Middle East and Africa.  Mike’s take?  Most of these machines are poorly made and have a life expectancy of only a few years. And Mike emphasizes there is little or no training for operators and no machine service support in these markets to fix a faltering machine. Consequently, the result often is a poorly made panel on a faulty machine. Continue reading
