The True Beauty of Corrugated Metal

corrugated_metal_redOne of the biggest myths about corrugated metal siding and roofing is that it is ugly and drab. Visions of poorly designed Quonset huts and mundane backyard sheds might even come to mind.  In reality, corrugated metal is a versatile, innovative, and often stunningly beautiful building material that is at the vanguard of the modern architectural movement.

Invented by Henry Palmer in the 1820’s, corrugated metal is to this day a common building material all throughout the world. Its staying power comes from a combination of durability (they last 2 to 3 times longer than asphalt shingles), utility, manageable weight, corrosion-resistance, and cost. For years, it got the reputation as an inexpensive and bland alternative to other roofing and siding materials, like wood, tile, and stone. However, over the past decade, designers and architects have fallen in love with the versatility of corrugated metal.

Whether it is found in the middle of the hippest new urban neighborhood, on a beach, or down a classic country road; corrugated metal stands out as unique and attractive. Some of the biggest names in modern architecture, including Frank Gehry, Renzo Piano, and Glenn Murcutt, all have and continue to rely heavily on corrugated metal siding and roofs to create some of the most iconic buildings the world has seen.

Another reason for the corrugated metal renaissance is its unique ability to be energy efficient. Being “Green” is a major part of modern architecture. Properly coated corrugated metal roofs are not only appealing to the eye, but can also cut heating and cooling costs dramatically.

One can only hope the myths surrounding corrugated metal will vanish as more architects, designers, and building owners discover its true beauty.

Maintaining Corrugated Metal Roofs: Preventing White Rust

Posted by Ken Carlton

 White RustCorrugated roofing and siding is popular with homeowners and businesses alike, thanks to beneficial attributes such as long life, easy installation, and low maintenance requirements. Most corrugated products are made from galvanized steel. Galvanization is the process of applying a thin layer of zinc on the surface of the metal to protect it from rust (oxidization) and corrosion. 

Galvanized steel products are designed to last for many years in roofing and siding applications. However, it is very important to know that packaged bundles of corrugated products must be stored indoors, in a dry environment. Improper storage of stacked sheets (i.e. outdoors, or in environments where moisture can form between sheets) exposes galvanized steel to white zinc corrosion, or “white rust.” White rust is the result of electrolytic action which takes place between the steel sheets when water exists without oxygen.   

White rust’s corrosion usually appears as a white deposit on one or more areas of the galvanized metal. If seen wet, it will feel waxy in texture, when dried it can feel brittle and hard. If this is spotted early enough, it can be treated and prevented. The good thing is that the corrosion of the zinc is only on the surface level and hasn’t penetrated to the metal. However, if left unattended, the zinc will be further eroded and will leave the metal unprotected and vulnerable to oxidization. Of course, it can be unsightly as well, so tackling the issue when it first is noticed is important.

Here are a few tips that can help prevent white rust and what you can do if it develops on your roof, siding or other places that utilize corrugated metal:

  1. Most importantly, be certain that the materials are stored in a way that will provide enough air to allow the zinc coating to dry and protect. Also, be certain that in the storage area that the zinc coating doesn’t come into contact with the various elements that could begin the corrosion process for the zinc. This is the most critical part of maintaining rust free corrugated metal. Too many suppliers and wholesalers fail to properly store the corrugated metal.

  2. Remove any item that may be causing destructive corrosion in areas already damaged. This could be strapping or other items used in storage. If the white rust has begun while the product is on the building, make sure that it isn’t in contact with things like copper pipes or lead, etc.

  3. Pour white vinegar over any areas that display white rust. Allow the vinegar to sit for five minutes, then rinse and wash the area with warm water. For light rusted areas, this should remove the stain. If so, apply a coat of zinc-rich water or perhaps a solvent-based rust resistant primer.

  4. If the vinegar doesn’t remove the white rust, scrub off the rest of the stain with sandpaper until the white coating of the rust has been removed. Do this for all areas of the surface that may be exhibiting white rust.

  5. Rinse the sanded area with warm water, dry with a clean cloth rag.

  6. Apply a layer of zinc-rich primer to the sanded areas. Wait until dry, brush on a coat of galvanized iron primer. Paint the entire roof or siding. Let dry.

  7. You may then finish the process by painting on a layer of exterior paint for metal.

We Want You… To Tell Us What You Want

As a company that has been around for as many years as we have, we have received countless numbers of requests from clients in regards to products or capabilities they were looking for. Since we pride ourselves on always meeting the needs of every client, it is important to us to consider each request and find a way to integrate the core qualities into our business. That is exactly how we have grown from a company focused only on roofing and siding products to that of one serving OEMs, passenger rails, and military supplies as well. Over the years, we have learned how to grow and adapt to the changing needs and technologies of the industry. Today, it is no different.

To be more specific, we recently were approached about becoming a one-stop shop for the roofing and siding industry. One customer needed all new roofing and siding materials, including the flashing and other types of equipment. At the time, we were only able to provide the flat sheet of material—the customer would have had to go to another vendor in order for the flashings. In order to make it more efficient and cost effective for our customers, we have begun offering flashings and panels as well. Why not take advantage of the opportunity to become more reliable and dependent to our audience?

That’s not where we want this to end. As we are looking to expand even further in the coming years, we invite you to help with our product selection. We want to become more of a one-stop shop with all of the products we offer. We invite you to let us know any suggestions!
