Flat vs. Striated Standing Seam Panels

One of the most common decisions customers face is choosing between flat and striated standing seam panels. In this blog, we’ll break down the key differences, explore the impact of oil canning, and help you decide which finish is best suited for your project.

Flat Panels

Flat standing seam panels feature a smooth surface between seams, giving a clean, minimalist look that appeals to architects and modern designers.

Benefits of Flat Panels:

• Modern Aesthetic: Clean lines and a crisp appearance ideal for contemporary designs.

• Smooth Texture: Great for exterior walls or facades where texture is not desired.

• Architectural Appeal: Flat panels often photograph well and are visually striking on commercial or residential builds.

Considerations:

• Oil Canning Risk: Flat panels are more prone to a cosmetic phenomenon called oil canning, which causes visible waviness in the flat areas due to expansion and contraction of the metal.

• Extra Precautions Needed: Installers may need to use thicker gauges or backer rods to minimize oil canning effects.

Striated Panels

Striated panels have shallow, continuous indentations (striations) running along the flat part of the panel. These are designed to add strength and reduce visual distortions.

Benefits of Striated Panels:

• Reduced Oil Canning: The number one reason to choose striations — they help disguise or reduce the appearance of waviness.

• Added Rigidity: The striations add minor structural strength to the panel without altering its basic look or performance.

• Balanced Aesthetic: You still get a clean look, but with subtle texture that improves appearance over time.

Considerations:

• Less Sleek Look: For designers seeking a glass-smooth facade, the texture may not be preferred.

• Slight Shadowing: Depending on sunlight and roof orientation, striations may cast light shadows visible from certain angles.

When to Choose Which?

Choose Flat Panels if:

• You prioritize a sleek, uninterrupted surface

• The roof or wall is not in direct sunlight or highly visible

• You’re using heavier gauge metal or taking other oil canning precautions

Choose Striated Panels if:

• You want a more forgiving, uniform finish

• The panels are wide or in lighter gauges

• The surface will be visible under changing light conditions

What Is Oil Canning?

Oil canning is a cosmetic issue in metal panels where the flat areas appear wavy or distorted under certain lighting conditions. It’s not a structural defect, but it can affect the appearance of the roof or wall. This effect is more pronounced in flat panels, particularly those with large widths or thinner gauges.

While oil canning doesn’t impact the performance of the panel, it can detract from the visual appearance. Striated panels are one of the most effective ways to minimize this effect.

Simulated Rust vs. Cold-Rolled Steel: Understanding the Differences & Benefits

Steel is a versatile material used across industries, from construction to architectural design. However, the choice between simulated rust and cold-rolled steel can impact a project's durability, aesthetics, and maintenance requirements. In this blog, we’ll explore the key differences between these two materials and when to use each one.

What is Simulated Rust Steel?

Simulated rust steel, also known as pre-weathered or rusted-look steel, is designed to give the appearance of aged, oxidized metal without actual corrosion. This effect is typically achieved through specialized coatings, treatments, or pre-finished steel surfaces that replicate the natural rusting process.

Benefits of Simulated Rust Steel:

• Aesthetic Appeal: Provides a rustic, aged look without structural deterioration.

• Low Maintenance: Unlike real rusted steel, it does not require ongoing treatments to prevent excessive corrosion.

• Durability: Coatings prevent further oxidation, ensuring longevity in various environments.

• Versatility: Ideal for decorative panels, architectural facades, interior designs, and signage.

What is Cold-Rolled Steel?

Cold-rolled steel is manufactured by rolling steel at room temperature, creating a smoother, more precise finish. It is commonly used in applications where precision, strength, and a refined surface are necessary. Cold-rolled steel is also an option for customers who want a rusted appearance over time, as it naturally rusts when exposed to the elements.

Benefits of Cold-Rolled Steel:

• Higher Strength: Increased hardness and tensile strength compared to hot-rolled steel.

• Smooth Surface: Ideal for applications requiring uniformity and a clean finish.

• Better Precision: Tight dimensional tolerances make it suitable for structural and industrial uses.

• Improved Fabrication: Works well for forming, bending, and welding in manufacturing.

• Natural Aging Effect: Over time, cold-rolled steel develops a rusted patina when exposed to moisture and air, creating an organic weathered look.

When to Choose One Over the Other

• For Decorative and Architectural Uses: Simulated rust steel is the ideal choice when you want the aged aesthetic without worrying about structural degradation.

• For Structural and Industrial Applications: Cold-rolled steel provides the strength and precision needed for load-bearing projects and fabricated components.

• For Customers Wanting a Natural Rusted Look: Cold-rolled steel is the better option if you prefer a surface that rusts naturally over time for an organic, evolving appearance.

• For Cost Considerations: Cold-rolled steel is often the more economical choice for projects requiring bulk steel materials.

• For Environmental Exposure: Simulated rust is better for decorative use in exposed environments, while cold-rolled steel may require additional treatments to prevent unwanted corrosion.

Why Galvanized Steel is the Ideal Choice for Dairy Facilities

When it comes to dairy production, maintaining a clean, hygienic, and durable environment is essential. From milking parlors to storage areas, every part of a dairy facility must meet strict health and safety standards. One material that consistently rises to the challenge is galvanized steel. Its unique properties make it a popular choice for dairy farms and processing facilities worldwide. But why is galvanized steel so well-suited for dairy environments? Let’s explore the key benefits that set it apart.

While galvanized steel may have a higher upfront cost than untreated steel or other materials, it offers long-term cost savings. The initial investment is offset by reduced maintenance, fewer repairs, and a longer lifespan. Unlike paint or coatings that may chip or peel, the zinc layer of galvanized steel bonds metallurgically to the surface, providing permanent protection. This durability eliminates the need for regular repainting or re-coating, which saves both time and money for dairy operators.

5. Environmentally Friendly Choice

With growing attention on sustainability in agriculture, many dairy farms aim to reduce their environmental impact. Galvanized steel supports this goal in several ways. First, it’s 100% recyclable, meaning it can be repurposed at the end of its life. Second, its long lifespan reduces the need for frequent replacements, lowering resource consumption. Third, the protective zinc coating is non-toxic, making it safer for the environment and the livestock that come into contact with it.

6. Versatile Applications in Dairy Facilities

Galvanized steel is used in a wide range of applications within dairy facilities, including:

• Structural Components: Beams, columns, and frames for barns, parlors, and processing areas.

• Equipment: Milk tanks, piping, and conveyor systems.

• Fencing and Gates: Durable barriers for livestock enclosures.

• Storage Solutions: Feed bins, silos, and shelving units.

• Ventilation Systems: Ducts, grates, and ventilation covers to manage airflow and temperature.

The versatility of galvanized steel means it can be used for nearly every part of a dairy operation, supporting efficiency, cleanliness, and safety from production to processing.

7. Compliance with Health and Safety Standards

Dairy producers operate under strict health and safety regulations, and galvanized steel helps them meet compliance requirements. The USDA and FDA set hygiene and safety guidelines for dairy facilities, especially regarding surfaces that come into contact with food. Since galvanized steel is non-reactive and easy to clean, it’s an excellent choice for meeting regulatory standards. By using galvanized steel, dairy operators can reduce the risk of foodborne illnesses and ensure safe, high-quality milk production.

Conclusion

Galvanized steel’s unique combination of corrosion resistance, durability, hygiene, and cost savings make it a standout material for dairy operations. Its ability to endure harsh environments, support hygiene protocols, and meet regulatory compliance makes it a vital component of modern dairy farming. By choosing galvanized steel for equipment, structures, and storage, dairy producers can reduce long-term costs, increase operational efficiency, and maintain the highest safety standards. Whether you’re building a new facility or upgrading existing structures, galvanized steel offers a solution that’s built to last.

Buy America vs Buy American

Understanding the Difference Between "Buy America" and "Buy American" Steel Requirements

In the construction and manufacturing industries, sourcing materials, particularly steel, often comes with a set of guidelines and regulations. Two commonly referenced policies are the "Buy America" and "Buy American" provisions. While they may sound similar, these regulations differ in their scope and application, especially when it comes to steel. Understanding these differences is crucial for businesses aiming to comply with government contracts and projects. Here’s a breakdown of what sets these two provisions apart.

Buy America Act

The Buy America Act is specific to transportation and infrastructure projects funded by the federal government, such as highways, bridges, railroads, and public transit systems. It mandates that all steel and iron used in these projects must be produced in the United States, from the initial melting stage through to the final manufacturing. The goal is to ensure that federal funds are spent on U.S.-produced materials, supporting the domestic steel industry.

Key Requirements:

• Domestic Production: The steel used in Buy America projects must be entirely manufactured in the U.S. This includes all steps in the production process, from smelting to the final product.

• Applicability: Buy America applies specifically to projects funded by the U.S. Department of Transportation (DOT) and its agencies.

• Waivers: In some cases, waivers can be granted if domestic products are not available in sufficient quantity or quality, or if using them would significantly increase project costs. However, these waivers are becoming increasingly rare as the government pushes for more stringent adherence to Buy America requirements.

Buy American Act

The Buy American Act has a broader scope and applies to all government procurement, not just transportation or infrastructure projects. This law requires that federal government purchases of goods, including steel, must be primarily made from U.S.-made materials. However, the Buy American Act is less stringent than Buy America in several key ways.

Key Requirements:

• Substantial Transformation: Under the Buy American Act, the steel does not need to be 100% produced in the U.S. It can include foreign components, as long as the final product is "substantially transformed" in the United States, meaning significant manufacturing processes occurred domestically.

• Applicability: This act applies to all government procurement contracts, including defense and other federal agencies, but it doesn’t extend to state or local projects unless federal funds are involved.

• Waivers and Exceptions: There are numerous exceptions under the Buy American Act, including when foreign-made products are significantly cheaper, or when U.S. goods are not readily available. Additionally, trade agreements with other countries can allow for foreign products to be treated as if they were U.S.-made.

Differences in Steel Requirements:

1. Domestic Production vs. Substantial Transformation:

   • Under Buy America, all steel must be entirely made in the U.S., from raw material through the final product. No foreign steel is allowed in the process.

   • Under Buy American, foreign steel can be used, as long as the final product undergoes significant manufacturing in the U.S. This means some components could come from abroad, but the product must be substantially transformed domestically.

2. Scope of Projects:

   • Buy America applies specifically to infrastructure projects funded by the DOT or its agencies.

   • Buy American covers all federal procurement, meaning it applies to a broader range of projects but with more flexible requirements.

3. Waivers:

   • Waivers under Buy America are harder to obtain, as the focus is strictly on supporting U.S. steel production.

   • Buy American allows for more waivers and exceptions, making it easier for contractors to use foreign materials if they meet certain criteria, such as cost savings or availability.

Why the Difference Matters

For companies involved in steel manufacturing or supplying, understanding the difference between these two provisions is critical to maintaining compliance with federal contracts. Misinterpreting the rules could result in costly project delays, penalties, or even disqualification from bidding on federal projects. Contractors working on infrastructure projects need to ensure that all their steel meets the strict Buy America requirements, while those involved in other government procurement may find some flexibility under the Buy American Act.

Conclusion

While the terms "Buy America" and "Buy American" might seem interchangeable, their requirements, particularly regarding steel, are distinct. The Buy America Act enforces a stricter, more localized approach to steel production for transportation projects, while the Buy American Act provides more flexibility, allowing for the inclusion of foreign materials as long as they undergo substantial transformation in the U.S. For businesses navigating these regulations, staying informed on the differences ensures smooth project execution and continued compliance with federal standards.

By understanding these nuances, contractors and suppliers can better align their practices with government requirements and maintain a competitive edge in federally funded projects.

What is the difference between PBR and R-Panel?

PBR (Purlin Bearing Rib) panels and R-Panels are both commonly used in the construction and roofing industries, particularly for metal buildings. While they appear similar, there are some key differences that set them apart. Here's a breakdown:

1. Design and Structure:

• PBR Panels: Include an extra purlin-bearing leg (hence the name) that provides additional support and overlap where panels meet. This feature enhances the strength and reduces the likelihood of panel sagging at the purlin connections.

• R-Panels: Lack the purlin-bearing leg, which makes them slightly less rigid at overlaps compared to PBR panels.

2. Overlap and Installation:

• PBR Panels: Easier to install on purlins due to the purlin-bearing leg. The overlap ensures a tighter, more secure connection and improves water resistance.

• R-Panels: Typically installed with a simple overlap that doesn’t have the additional bearing support. This makes them slightly more prone to water infiltration at the seams in less-than-ideal conditions.

3. Strength and Durability:

• PBR Panels: Offer superior strength due to the extra purlin-bearing support, making them better suited for heavy-duty applications and longer spans.

• R-Panels: Generally strong but may require additional purlins for equivalent performance, particularly in areas with heavy snow or wind loads.

4. Applications:

• PBR Panels: Commonly used for both roofing and wall applications on commercial, agricultural, and industrial buildings. Their enhanced strength makes them ideal for projects requiring high durability.

• R-Panels: Often used in less demanding applications, such as for walls, light-duty roofing, or temporary structures.

5. Cost:

• PBR Panels: Slightly more expensive than R-Panels due to the added material in the purlin-bearing leg.

• R-Panels: Lower cost makes them an economical choice for projects where the added strength of PBR is not required.

6. Appearance:

• Both panels look very similar with trapezoidal ribs, but upon close inspection, the additional purlin-bearing leg on PBR panels becomes noticeable.

Summary:

If you’re working on a project that requires maximum durability and reliability, especially for roofing, PBR panels are the better choice. For lighter-duty or more cost-sensitive projects, R-Panels can be a good option. Both panels are widely used in the industry and perform well in various applications when installed correctly.
