Which one is right for you?…Features and Benefits of Three Metal Building Types: Red Iron, Cold Rolled and Tube Steel
Considerations
When considering a pre-engineered metal building for commercial, equestrian, or even residential use, choosing the right type of steel framing is crucial to your satisfaction. The three primary types of metal framing used in construction are Red Iron Steel, Cold Rolled Steel, and Light Gauge Tube Steel. Each has its own advantages and ideal applications. In this article, we will break down the key differences between these materials and explore their benefits. Since we at Vista Point Builders deal primarily in Pre-engineered Red Iron, we will discuss when Red Iron steel might be the best option for your needs.
Pre-Engineered Red Iron Building
Red Iron Steel
Red Iron Steel, also known as I-beam or structural steel, is one of the most common choices for large-scale metal buildings. The name "Red Iron" comes from the traditional red oxide coating applied to protect the steel during transportation as well as from rust and corrosion. Depending on the application, the steel may be painted or even powder coated a different color.
Key Characteristics
Heavy-Duty Strength: Red Iron Steel consists of thick I-beams and columns, making it the most robust option for large-scale buildings.
Long Lifespan: The red oxide coating helps protect against corrosion, ensuring durability over decades.
Welded or Bolted Assembly: This steel is often pre-fabricated and bolted together onsite, reducing construction time.
Wide Clear Spans: Allows for column-free interiors, ideal for open spaces like warehouses, aircraft hangars, and horse arenas.
Benefits of Red Iron Steel
Exceptional Strength: Suitable for large buildings with heavy loads or high ceilings.
Fire Resistance: Holds up better in extreme heat than other steel types.
Low Maintenance: Requires little upkeep over its lifespan.
Great for Large Structures: Perfect for buildings over 50 feet in width.
Use Cases for Red Iron Steel
Warehouses & Distribution Centers: Requires large open spaces and heavy load-bearing capability.
Manufacturing Facilities: Strong enough to support cranes, conveyor systems, and other industrial equipment.
Aircraft Hangars: The ability to support large doors and clear spans makes it ideal.
Agricultural Buildings: Often used for barns, equipment storage, and grain storage structures.
Retail and Commercial Spaces: Shopping centers and large retail stores benefit from its durability and open layouts.
Cold-Rolled Steel Building
Cold Rolled Steel
Cold rolled steel is processed at room temperature, giving it a smoother, more precise finish than Red Iron. It is commonly used in applications where appearance and tighter tolerances are required.
Key Characteristics
More Precise & Smooth Finish: The manufacturing process results in more exact dimensions and a refined surface.
Stronger Tensile Strength Than Hot-Rolled Steel: Due to increased density from the cold rolling process.
Lighter Weight Than Red Iron: Making it easier to transport and handle.
Less Resistant to Corrosion: Requires additional coatings or galvanization to prevent rust.
Benefits of Cold Rolled Steel
Higher Tensile Strength: More strength for its weight compared to hot-rolled steel.
Ideal for Prefabrication: Easier to shape and cut into precise parts.
Cost-Effective for Smaller Buildings: While not as robust as Red Iron, it is a more economical choice for mid-sized structures.
Use Cases for Cold Rolled Steel
Small to Medium-Sized Commercial Buildings: Office spaces, small warehouses, and storage units.
Garages & Workshops: More durable than light gauge steel but not as heavy as Red Iron.
Residential Metal Structures: Carports, backyard shops, and ADUs (Accessory Dwelling Units).
Interior Framing: Often used for interior walls, partitions, and shelving systems.
Light Gauge Tube Steel
Light Gauge Tube Steel
Light Gauge Tube Steel, often referred to as hollow structural sections (HSS) or galvanized steel tubing, is made from thin sheets of steel that are cold-formed into rectangular, square, or circular tubes.
Key Characteristics
Lightweight Yet Durable: More lightweight than both Red Iron and Cold Rolled Steel but still strong for smaller structures.
Corrosion Resistance: Often galvanized to prevent rust and extend longevity.
Easy to Work With: Requires no welding—can be assembled using screws and bolts.
Most Affordable Option: Cost-effective for small to mid-sized structures.
Benefits of Light Gauge Tube Steel
Flexible Design: Easier to modify or expand.
Lower Construction Costs: Less expensive than Red Iron or Cold Rolled Steel.
Quick Installation: Faster to assemble and install, making it ideal for DIY or quick projects.
Use Cases for Light Gauge Tube Steel
Carports & Small Garages: Lightweight yet strong enough to support roofs and light loads.
Sheds & Storage Units: Cost-effective for temporary or permanent storage solutions.
Temporary Structures: Exhibition stands, kiosks, and portable offices.
Agricultural Shelters: Greenhouses, animal enclosures, and small barns.
When is Red Iron Steel the Best Fit?
While Cold Rolled Steel and Light Gauge Tube Steel have their advantages, Red Iron Steel is the top choice for clients who need maximum strength, longevity, and large clear spans. Here are some situations where Red Iron Steel is the best fit:
Large Industrial or Commercial Buildings – If you need a structure over 50 feet wide, Red Iron Steel provides the necessary strength and support.
Heavy Load Requirements – When the building needs to support cranes, mezzanines, heavy equipment, or storage racks, Red Iron is ideal.
Long-Term Durability – If you are looking for a structure that will last decades with minimal maintenance, Red Iron is the best investment.
Extreme Weather Conditions – In regions with high winds, heavy snow, or fire prone areas, Red Iron offers superior resistance.
Clear Span Design – If an open floor plan without internal support columns is a priority, Red Iron provides wide, unobstructed interior spaces.
Conclusion
Choosing between Red Iron Steel, Cold Rolled Steel, and Light Gauge Tube Steel depends on the size, budget, and intended use of the metal building.
Red Iron Steel is the strongest and most durable, ideal for large-scale, agricultural, and industrial buildings.
Cold Rolled Steel is best for mid-sized structures, offering a balance between strength and affordability.
Light Gauge Tube Steel is the most cost-effective, perfect for small-scale and lightweight applications.
For clients looking for a long-lasting, highly durable, and structurally superior building, Red Iron Steel is the best option, especially for large warehouses, horse arenas, and commercial spaces. By understanding the unique advantages of each metal type, you can make the best choice for your specific needs.
