If you’re a contractor who installs standing seam metal roof and wall systems, you significantly rely on coil manufacturers and suppliers to provide high-quality material for your projects.
If you are looking for more details, kindly visit LITONG.
Whether you’re rollforming your own panels on-site or purchasing panels from a regional manufacturer, you might run into a supplier that is advertising a low price for what seems like a quality metal sheet and coil product.
However, these low-cost coil suppliers are often cutting corners, including lacking proper quality assurance procedures, supplying a lesser quality product, or offering little to no post-sales support, all of which can negatively affect you and your contracting business.
At Sheffield Metals, we don’t claim to be a low-cost coil supplier. We offer our metal products at a competitive price level, which allows us to:
- Buy domestic steel the majority of the time.
- Coat the metal in a high-performance paint system.
- Slit and process the coil in-house.
- Provide valuable warranties, panel profile engineering, technical and design assistance, and a variety of other services.
In the article, we’re going to discuss the top six problems that your contracting business could encounter if you choose the low-cost metal coil supplier.
The most apparent problem with buying from a low-cost coil supplier is that you run the risk of getting lower-quality metal to work with. This can cause issues in the long and short run, including premature failure, forming problems, little to no offered warranties, and more.
While this affects your customers directly, problems that stem from cheap, low-quality materials also reflect poorly on your business. It could stir up bad reviews, money and time lost in repairs, or worse.
Some common reasons that metal coil is offered at a lower price include:
- The metal is imported and/or is difficult to track the original manufacturing source.
- The metal isn’t mill certified, and the metal make-up (i.e., steel, aluminum, etc.) can’t be verified. This metal could have been acquired on the secondary or reject market.
- The metal is not intended for use in architectural standing seam metal panel systems.
- For example, lower quality and thinner metal sheet/coil are often used for agricultural projects, exposed fastener roofs, gutters, and other applications.
- Some companies buy one type of metal for dual purposes and the metal might not be ideal for one of those end use purposes.
- The metal doesn’t have an adequate coating weight for a standing seam metal roof.
- A painted Galvalume sheet/coil coating weight is typically AZ50, and an unpainted Galvalume sheet/coil coating weight is typically AZ55. There are coil suppliers who use AZ40 or lower, which is a lower quality when compared to AZ50.
- The supplier is using paint, rather than metal, to meet the minimum advertised thickness or gauge.
- The metal is not easily formed into a profile and may even create issues with a standing seam rollforming machine.
- The ideal steel used is going to be a structural grade steel (Grade 50) with a minimum yield of 50 KSI, which is in accordance with UL testing. Here’s a quick breakdown of varying steel grades:
- Grade 33 – Construction grade, or Grade 33 steel, is most commonly used for rain-ware goods, such as gutters. It has a lower yield and is not as strong as structural grade steel (above 50 KSI).
- Grade 50 – Anything within the 50 to 65 KSI range, which should result in elongation in the 20%+ range. This allows for the rigidity and tight bends needed for engineered standing seam metal roofing systems. UL commonly recognizes structural grade steel for engineered applications in metal roofing systems.
- Grade 80 – A stronger, higher carbon steel most commonly used in agricultural panels and face-fastened systems. However, it’s not a good alternative for standing seam because it can’t make the tight bends that Grade 50 steel can make.
Beyond problems with the metal substrate, a low-cost coil might also have a cheap or low-quality paint system coating the metal. The paint quality relies on the resin type, which affects the longevity of the color and overall system performance.
Best Resin: PVDF (Polyvinylidene Fluoride)
In the architectural standing seam metal roofing industry, most metal coils are expected to have a PVDF (polyvinylidene fluoride) resin coating system, commonly referred to as Kynar 500® or Hylar ®. PVDF resins are the best protective coatings available to stand up to extreme temperatures, sun exposure, oxygen, humidity, and even pollution particles in the atmosphere.
The minimum requirement for a PVDF paint system is 70% PVDF and 30% acrylic, but some suppliers sell products with less than 70% PVDF in the paint system. The lack of PVDF will cause the paint to fade faster and affect the overall color integrity, allowing a manufacturer to sell the metal at a low price.
Better Resin: SMP (Silicone-Modified Polyester)
SMP coatings are a step below PVDF in terms of quality. This resin consists of a combination mixture of polyester and silicone materials. SMPs are known to be a great option to defend against extreme weather conditions.
SMP is still a good paint system for many metal roofing applications, but in terms of warranties and longevity, PVDF is the clear winner. It’s critical to watch out for businesses that might be marketing or selling SMP coated coil as PVDF, which has happened with less credible suppliers.
Good Resins: Fluoroethylene Vinyl Ether (FEVE), Plastisol, & Polyester
All three of these resins, which you can read more in-depth about in this article, are available as coating options for metal sheet and coil. These products are all significantly cheaper than SMP and PVDF coated material because they don’t offer the same protection level.
Again, some suppliers may falsely advertise their coil as PVDF or SMP when it’s coated in a plastisol, polyester, or FEVE resin.
How to Make Sure The Paint System is Valid
The good news is that there are some ways to tell if a paint system is trustworthy, including:
- Checking to make sure the metal supplier uses a reputable paint supplier.
- For example, the well-known and world-renowned paint manufacturer Sherwin-Williams supplies the paint that coats Sheffield Metals’ sheet and coil products. If a metal sheet and coil supplier get their products coated by an unknown paint supplier, you should question their products’ reliability.
- Asking the coil supplier what paint company supplies their coating(s).
- Most reputable metal suppliers are transparent about what company they use as their paint supplier. If the supplier doesn’t know or is reluctant to tell you who their paint supplier is, it could be because the supplier has a bad reputation or doesn’t have quality paint/resin systems.
- Ensuring the paint supplier offers a finish or paint warranty.
- When it comes to paint systems on flat metal products, warranties are one of the most significant selling points. A paint warranty is a guarantee from a manufacturer/paint supplier that the paint system applied to the metal substrate will not degrade to a certain degree within a specific time frame. This is why it’s critical to make sure a quality paint warranty is offered, especially because you can use it as a valuable selling tool.
- Checking that the paint supplier has a good track record of honoring and responding to claims.
- Beyond offering a warranty, you’ll want to verify the paint supplier is responsive to claims, especially where the paint system was defective. You can find this out by asking around the industry or asking for warranty claims policies and procedures.
- Even if a paint supplier offers a warranty on their product, it’s important to know that they will actually stand behind that warranty if a problem arises. Problems can happen in any manufacturing process, but how the company handles it is what sets them apart.
Problem #3: The material doesn’t adhere to testing standards or is too inconsistent for engineering requirements.
The third problem with cheap metal sheets and coils relates to engineering. Most reputable manufacturers test their metal coil and offer panel profile engineering, which means they adhere to many of the stringent testing standards and requirements used for residential and commercial projects.
Engineering requirements dictate the type of material used in testing. With lesser grade material that might have more inconsistencies due to a lack of quality control processes, it is hard to know if the material you are getting is what was actually tested, if there was any testing done at all.
Engineering is designed to not only keep your customer and their property safe, but it also keeps your contracting business safe. Having engineering can substantiate the performance of the roof you’re installing, so why wouldn’t you always want to use an engineered product?
For reference, make sure to ask if the supplier’s metal sheet or coil is usable for profiles that have passed and received the engineering reports for:
- Wind uplift testing
- Air infiltration testing
- Water penetration testing
- Water submersion testing
- Impact resistance testing
- Fire rating
- Florida Building Code (FBC) Approval (if applicable)
- Texas Department of Insurance (TDI) Approval (if applicable)
Another indicator of if a coil supplier is questionable or if their metal coil is subpar is whether they offer warranties, including paint/finish, substrate, and weathertight warranties.
It’s simple: Metal roofing should have a warranty of some kind. Metal is a high-quality product that comes at a higher price point than many other roof types, which is why reputable manufacturers will stand behind their products with warranties. Plus, not only should there be warranties offered, but the warranties should be straightforward as to what is and is not covered, and for how long.
As a contractor, warranties also set your business apart from your competitors, as warranties strengthen your credibility and trustworthiness to prospective customers.
While paint and substrate warranties are available with the metal sheet and coil upon purchase, the opportunity to offer a weathertight warranty for commercial roofing projects is a game-changer. It not only certifies that the products used on the roof are high-quality, but it verifies that your business correctly installs the high-performance roofing system. So, if a coil supplier can offer a weathertight warranty option, it’s more likely that they’re a credible business.
Additionally, all warranty documents should be easily accessible and/or available on a supplier’s website. If you’re unable to find this information or the supplier is vague about what they can offer, you should question their ability to provide quality products.
Some low-price coils and sheets are known to be incompatible with in-plant and portable rollforming machinery. Alternatively, if the cheaper coil will run through a rollforming machine, it might produce deformed or unusable panels.
Some examples of these occurrences include:
- The metal shows signs of oil canning – Before you rollform any panels, it’s best to check for signs of oil canning on the coil or sheet. For reference, oil canning is the perceived waviness of a metal panel and is an inherent characteristic of light-gauge, cold-rolled flat metal products. If the low-cost coil already has oil canning, running it through a rollforming machine to make panels will not make the oil canning go away; it might even make it worse.
- There is a camber in the coil – According to New Tech Machinery, camber is when sheet metal has a stretched edge and curves slightly from side to side. If you’re buying low-cost material, it’s critical to check for any cambering, as it shouldn’t be run through a rollformer. It will create uneven panels and can affect the machine by causing a need for adjustment.
- The metal and or paint cracks or fractures when rollformed or folded – On occasion, issues like paint cracking or fracturing can happen when fabricating metal.
- The metal is too thin to be rollformed – Rollforming machines have specific thicknesses that are used to form panels. If you get a low-cost coil that is too thin, it likely won’t form correctly or could even create a problem within the machine, like metal getting stuck or jammed up in the forming rollers.
- The metal is not a proper width for a rollforming machine – Some low-cost metal suppliers might not slit the metal to the correct width for a rollforming machine to make a specific profile. Or, the width might not be consistent throughout the entire length of the coil, which could also cause forming issues.
Problem #6: The supplier doesn’t offer support for quality issues, resources, and more.
Finally, one of the most prevalent problems associated with buying low-cost metal is the lack of resources and assistance you can expect from the supplier. There is always a reason that the material is cheaper, and a lot of it relates to the support offered when you become a customer.
Some of the standard support issues we’ve come across with low-cost suppliers include:
- Uneducated or unhelpful sales representatives.
- Lack of help when there’s a quality or processing issue with the metal sheet or coil products.
- No technical department to assist with installation questions, engineering requirements, warranties, project bidding, and other technical topics.
- Little to no complimentary value-added services, such as a take-off service, marketing support, architectural assistance, a color visualization tool, and more.
- No training or educational resources available.
Choosing the low-cost metal sheet and coil supplier could lead to more money lost in the long run. Plus, it’s typically not worth risking your reputation on choosing materials that are the lowest price.
So, if you’re in the market for buying metal sheet and coil products, the best thing to do is research and learn about the different manufacturers and options available to you. Then, use your best judgement to pick the supplier that suits you and your business.
To get you started, here are some questions you might consider asking:
- Where do you buy your raw materials from? Foreign or domestic suppliers?
- Is your metal mill-certified?
- What company supplies your paint or coatings?
- What resin is used on your sheet and coil products?
- Has this metal been tested for use on engineered panel profiles? Which ones?
- What are the warranties I can offer my customers or clients with this metal?
- Do I have access to a sales representative, any complimentary tools, training opportunities, or other resources?

If you’re established in the business and have been fabricating metal panels for years, this article is also for you, as metal colors, styles, and finishes continue to evolve, and the industry isn’t the same as it was even just a couple of years ago. So, wherever you are in your rollforming journey, read on.
What to Look for When Choosing a Coil Supplier
Metal Coil Quality
Your customers expect the best value for their money, right? Yet sometimes, customers find adhesion issues, excessive chalking, or fading with cheaper paint systems. Or oil canning appears, especially in bright sunlight. In contrast, they may discover their roof won’t need replacing until their children reach retirement age. So, coil quality really makes a difference.
Suppliers offer a wide variety of gauges and finishes, and you’ll need to decide which are worth considering. More than one option may make sense.
While oil canning can be attributed to a variety of factors, including not adjusting the roll forming machine correctly, it can also be due to the quality of the coil. Anytime you receive coil from a supplier, make sure to check for material flaws and mistakes in the order. Also, keep a close eye on the coil for defects during the fabrication process.
Delivery Convenience
Some manufacturers ship nationwide, while others have regional or state distribution centers. Therefore, the project’s timeframe may be a determinant. If you need the coil as soon as possible, you may find the closest supplier can deliver the fastest (provided they have what you need). Otherwise, national companies may offer free shipping or have a greater selection, making them worth the wait.
Supplier Selection
The availability of any coil finish really depends on your customer’s preference. If they’re looking for a black matte finish, it’s easy to acquire from most suppliers. However, your options might be more limited if they’re after a specialty print such as a woodgrain, or a less common color, or a coil outside of the typical gauges found in standing seam roofing. Some suppliers also cater to custom designs that may suit the customer’s needs. Testing may be another aspect to consider if it’s required in the project specifications.
Customer Service
The rule of thumb is that you’ll save yourself money in the long run if you pay a little extra for good customer service rather than having to fight to have an order corrected. Suppliers can be resistant to taking back an order already delivered. Developing a relationship with a supplier will make receiving quality service more likely, as they’ll value you as a regular customer.
Coil Cost
Quality costs money. If your customer has a limited budget, find the best deal possible for what they’re looking for, but discuss the advantages of more expensive options. A higher-quality PVDF paint system will hold its color and offer more aesthetic value than a less expensive SMP paint system. Also, a high-quality paint system may offer a better warranty.
Still, you should make your recommendations for the material and coil gauge, as paying a little more for a thicker gauge may be worth it even in the short term. Also, they may be eligible for LEED credits if they choose a qualifying material.
In this article, you’ll find a list of metal coil suppliers. Metal panel contractors and manufacturers often use two or three coil companies, depending on their needs. You may find one here that you can add to your list of suppliers.

The Short View
You may have already curated a list of suppliers that you’ve worked with for years. However, as the metal market continues to evolve, it doesn’t hurt to review the different offerings. With the emergence of metal board and batten siding, innovative technologies creating synthetic replications of wood and custom designs and patterns are changing the face of metal construction.
When you contact a supplier, be sure to include the following questions:
- What warranties come with your metal coil?
- What guarantees do you make for delivery?
- How do you respond to incorrect orders or defects found in the material upon delivery?
Always check your order when it arrives. Document any defects, including images and coil samples. Also, check size and thickness to make sure they matche your order. Running bad coil through a rollforming machine doesn’t make it come out right on the other end.
The important thing is finding a supplier that is reliable, provides good customer service, and has the selection and quality you need.
