10 things to consider when buying a steel building

We have put together a list of 10 things to consider when buying a steel building.  With so many options, styles and companies to choose from, we discuss the 10 things you should think about as your going through the process.
  • Building Types

    Knowing how you are going to use your building can help determine the size and type of building you should consider.  For instance, a 12x12 shed for lawn maintenance may only need a light weight building whereas a 40x60 used for a garage/shop would need a more sturdy commercial style building.

    Red Iron I-beam steal building

    The only building we sellThe frame of the building is comprised of steel I-beam columns and rafters with cold rolled secondary members.  The main frame columns are engineered to be attached to the concrete foundation with anchor bolts.  We utilize 26 gauge metal panels for the roof and walls.  This is commonly referred to as a Pre-engineered or Red Iron steel building and is the only building product we sell.

    Pole Barn

    Wood frame building not sold by RenegadeThis building is framed by wood poles placed in the ground with wooden trusses and wood support for the roof and wall sheets.  Many times, thinner 29 gauge panels are used.  This building can flex and move under wind and snow loads which can affect the structure as well as the weather seal.

    Quonset Hut

    Arch style building not sold by RenegadeA rounded or arch style building with no internal framing similar to the old military style buildings.  The arch style makes this self supporting.   This design has limitations on width and the radius design decreases usable interior wall space.

    Tube Frame Carport

    Aluminum frame building not sold by RenegadeThis style building uses an aluminum square tube for the building structure. The building can be placed on concrete or gravel with nothing more than a mobile home anchor. Typically, thinner 29 gauge metal panels are used to sheet the building.
  • Local Regulations

    Most areas have a variety of local regulations in regards to what type of buildings you can have on your property as well as any property line setbacks.  In addition to local codes, many HOA's also have clauses that can dictate what finish is on the building.  In some cases, you can customize your steel building with brick or stone wainscot or you may even have to finish a couple of walls with some other materials.  These regulations can not only determine the look of your building but can dictate the size as well.

    30x40

  • Steel Building Size

    Working off of the regulations above, determining you building size not only requires thought on what you need to use the building for, but also what will fit on your property.   Aside from those constraints, deciding the size that fits your needs along with any room for growth is important.  When building a residential shop or garage, most customers only buy a steel building once.  When a business needs either their first building or additional buildings for expansion, the return on investment can be a deciding factor.  With all that in mind, lets look at a few things to consider.

    Basic building size chart

    This chart allows you to see a variety of building sizes up to 5,000 square feet.  At 30 foot wide, you have room to pull a car in, close the door and still have room to walk around the front of the vehicle.  40 and 50 widths allow for more room to work or more toys to store.  Of course the buildings can continue wider from there like 75', 100', 150' or even 200' wide.  Length wise, you can continue to add bays to get to whatever length you may require.

  • Steel Building Project Timeline

    When do you want to have your building delivered.  In years past, we quoted most buildings to have drawings completed in 2 weeks and the building delivered 6 weeks after that for an 8 week total turn around.  We wish we could get back to those days.  With the huge demand on steel mills and steel products in general since , we have seen lead times continue to get longer and longer.  As of the end of July we can offer two options for when you will get your building.  In some locations we can offer 14-16 weeks, in other areas it's 30+ weeks.  Depending on your situation, this may give you the time you need to do your clearing, dirt work, and work through the permit process.  We are always up front with you on what to really expect so that you are not surprised later.
  • Budget

    Knowing your budget is important before going into any project.  The cost of the building is only one piece of the puzzle.  You will need to include site prep, cost for your concrete slab and foundation, cost of the building, labor to erect, and any interior build out you may do.  Renegade Steel Buildings can help with the cost of the building kit, and your local contractors can furnish pricing for the other items.  Collecting all of these cost can help you stay on budget and determine what your ROI may be.
  • Steel Building Permit

    Knowing what is involved in obtaining a permit is a very important part of the process.  In some cases, you may not need a permit, in others you will and on commercial jobs is all but certain that you will.  Renegade Steel Buildings is a nationwide supplier of American made, Red Iron, pre-engineered steel buildings.  We are not general contractors and do not get involved in the permitting or building process.
  • Accessories

    There are a variety of accessories that you can add to you building for either added functionality or aesthetic appeal.  Knowing your options can help you get the building you want.

    Horizontal Sliding Steel Building Window

    A steel building sliding window offers both functionality and aesthetics.  Check out our standards to see why we like to provide a framed opening for windows.

    Steel Walk Door

    Every building needs access to get in and out.  A large roll up or sectional door may be great, but there are always times when you just need to walk into your building without opening a large door.  A walk door is just what you need.

    Interior Liner Panels

    One great way to finish the inside of your building and protect your insulation as well is with interior liner panels.  Made from the same material and panels as your wall panels, they provide a clean look for your interior walls.

    Hi R-Value Insulation

    We offer a few different options for insulating your steel building.  Our standard is a vinyl faced fiberglass insulation that can go up to R-19 value at 6" thick.  Beyond that we can also offer a liner system which allows you to increase your insulation R-38 or more.  Our metal building insulation page has much more information.

    Steel Building Vent Fan

    A great option for airflow in your steel building is to add a 36" or 48" vent fan.  With this fan placed high in the building across from a door opening or louvered vent can give you a nice cross flow of air to remove heat and ventilate your building.

    Wall Lights

    We are often asked about adding skylight panels to a steel building.  While the are great for adding natural light they have a couple of disadvantages as well such as sweating.  Another option that works well without the problems is adding wall lights.  This option allows light in your building without cutting holes in your roof.
  • Warranty

    Don't be fooled by wild warranty claims.  The industry standard is 1 year structural warranty against defect in material and workmanship.  The warranty on panels is a finish warranty against fading and typically starts at 25 years pro rata.  You may see some claiming a lifetime structural warranty.  Be sure to read that warranty statement to see what it actually covers.
  • Contract

    In many cases, your quote becomes your contract once signed.  The biggest thing we see when comparing quotes is that there is usually a good reason why someone has a cheaper bottom line.  Most times, something is missing from their quote whether it is doors, insulation or tax.  Once signed, you are only purchasing exactly what is on the contract so if a competitor verbally assured you they have something included, but it is not on their contract, you may end up paying more to get it later.
  • Bottom Line

    The bottom line is that there are many steel building companies to choose from, some reputable, some shady and some just downright pushy.  We strive to be upfront and honest with our customers.  That's why we give you realistic lead times, tell you what we can and cannot do, advise you to check your local codes and loads and help value engineer your building to get what you want as cost effectively as possible.  Do your homework, check out each company your considering and let us help you get the best building at a price your happy with.

Performance Indicators: Factors like tensile strength, yield strength, and flexibility can be performance indicators for selecting a suitable material grade.

Expert Tips: Consulting with material scientists or structural engineers can provide valuable insights into the most appropriate material for a specific application.

Quality Certification and Standards

ASTM Standards on Structural Steel Products

American Society for Testing and Materials, or ASTM, sets industry-wide standards for materials, including structural steel. These standards address chemical composition, mechanical properties, and manufacturing processes.

Complying with ASTM standards ensures that the steel meets the requirements for quality and safety. Compliance is often a prerequisite for projects, especially in regulated industries like construction and aerospace.

ISO Certification

The International Organization for Standardization (ISO) provides recognized certifications for various products and materials, including steel.

ISO certification indicates that the steel has met international quality benchmarks, making it suitable for projects that span different countries or must follow global standards.

Custom Standards

Custom standards might be developed for specialized projects or applications with unique requirements not covered by existing standards. Military projects, specialized research facilities, or unique architectural designs may require custom standards.

Regional and National Standards

Countries or regions may have their standards, which could be adaptations of international standards or independently developed guidelines. Examples are European EN standards and Japanese JIS standards.

Local or national standards may be mandatory for projects within specific jurisdictions, and checking for Compliance when sourcing structural steel is advisable.

Documentation and Verification

Often accompanies the product to certify that it meets the claimed standards. Independent entities may be hired to verify that the structural steel complies with all required standards.

Legal Implications

Failure to comply with quality certifications and standards can lead to legal consequences, including fines and project delays. Contracts often specify the quality standards to be met, and not complying with these could be a breach of contract.

Mechanical Properties

Tensile Strength

Tensile strength indicates how well a material can resist being pulled apart. It is an important factor in applications where materials will undergo tensile pressures. Usually measured in megapascals (MPa) or pounds per square inch (psi). For example, tensile strength is a key parameter in skyscraper construction, where steel has to support huge vertical loads.

Yield Strength

Yield strength defines the maximum stress that can be applied to the steel before it deforms permanently. In construction, this is especially important for ensuring structural integrity. It’s usually measured in megapascals (MPa) or pounds per square inch (psi). Bridges, for instance, require steel with high yield strength to endure dynamic loads like heavy traffic and wind forces without deforming.

Hardness

Hardness measures the resistance to deformation and is usually quantified using scales like the Rockwell or Brinell hardness scales. A higher hardness often indicates better wear resistance, which can be advantageous in applications like machinery components. In industrial machinery, harder steel can provide a longer lifespan for components like gears or shafts.

Ductility

Ductility describes how much a material can deform under tensile stress before breaking. Higher ductility can absorb more energy during deformation, making it valuable in earthquake-prone regions. Buildings in seismic zones often use steel with higher ductility to withstand the forces of an earthquake.

Fatigue Strength

Fatigue strength is the maximum stress a material can endure for several cycles without breaking. This property is particularly relevant in structures that experience repeated loading and unloading, like bridges or aircraft. For example, the steel used in aircraft landing gears needs high fatigue strength to endure repeated landings.

Weldability

Weldability refers to how well the material can be joined through welding without compromising its properties. Poor weldability can introduce weak points in the structure, compromising its integrity. High weldability can simplify construction and improve final quality in large projects where pieces are often welded on-site.

Dimensional Tolerances

Thickness

The thickness of structural steel directly affects its ability to withstand loads and stresses. Insufficient thickness can result in structural failure or a shorter material lifespan. Industry standards often define a narrow range of acceptable thicknesses. Going beyond these tolerances can compromise the structural integrity. Regular inspections using calipers or ultrasonic thickness gauges can help ensure the material falls within acceptable tolerances.

Length and Width

Exact dimensions in length and width are often necessary in construction planning, where every inch can matter. Any changes can affect everything from fit to the ability to make secure connections. Just like thickness, the length and width of structural steel are regulated by industry standards. Not following these can result in ill-fitting components, leading to project delays. Ruler tapes, laser distance measurers, and even traditional yardsticks can be used depending on the required level of accuracy.

Weight

The weight of the structural steel plays a big role in transportation costs. Exceeding weight tolerances might require specialized transportation methods, which can be costly. Weight directly impacts the ease of assembly. Heavier pieces might need more advanced lifting equipment or labor, increasing the project’s complexity and cost. Weighing scales with high precision are generally used to ensure the material falls within the specified weight tolerances.
