Metal Building Trusses and Framing
The truss and frame of your metal building end up shaping almost everything else about it, from the look of the structure to how wide you can make the open floor area. It’s a connected set of steel members that forms a triangle-like web, while a metal building frame is the heavier structural backbone that ties the whole thing together.
Both of these pieces of hardware are built to ASCE 7 standards and work together to keep your building standing strong against the weather and capable of withstanding its own weight.
This guide pulls together the basics so you can sort through the main truss styles used in 2025 and figure out which direction makes the most sense for your project before you’re knee-deep in quotes and specs.
Metal Building Trusses
Metal building trusses show up in more shapes than most people realize. Some are simple open-web styles meant for small workshops; others are built to carry serious loads inside huge structures. The most common options include:
Rolled-steel open-web trusses
Also known as cold-pressed steel, this truss system is light, efficient, and often used in smaller-to-mid-size buildings where you want to keep weight down but still have a strong roof structure.
Rigid frames
These aren’t exactly trusses, but they get lumped into the same conversation. They’re welded steel frames built for heavy-duty strength and wide floor plans.
Clear-span trusses
Ideal for when you want a big, uninterrupted interior area with no posts, no columns, and open room.
Common Truss Spans
In 2025, spans have settled into patterns that builders recognize right away. There's wiggle room on all of these numbers, but they give you a starting point.
| Truss System | Average Span |
| Standard Metal Trusses | 20’-60’ |
| Rigid Frames | 80’-120’+ |
| Clear-Span Trusses | 40’-100’+ |
Actual ranges change if you’re in a snow-heavy region, planning tall walls, or need interior support for equipment.
The Cost of Metal Building Trusses
Pricing a truss system isn’t simple, since its cost is generally wrapped up in the final building price, and you’ll almost always find a few surprises once engineering kicks in. Several things push the number up or down:
Span Length
The wider the building, the more steel goes into each truss or frame.
Load Design (snow, wind, seismic)
Your zip code can change the entire approach.
Framing Choice
Trusses and rigid frames behave differently, and one may be far cheaper depending on the use.
Bay Spacing & Roof Pitch
Small changes here can shift the steel requirements more than most people expect. For actual pricing, you can always call our experts at [Phone Number] for a custom quote.
Trusses vs. Rigid Frames
Both truss systems and frames support a building, but they do it in completely different ways:
- Trusses rely on many smaller connected members; rigid frames rely on heavy welded beams.
- Rigid frames usually win for tall eave heights and very wide spans.
- Trusses often work better for lighter-duty or budget-friendly layouts.
- Rigid frames accept overhead loads like doors and frame outs more easily.
- Truss systems sometimes require more assembly time because of the number of parts.
A 2025 Guide for Picking the Right Truss
Before choosing a framing type, it helps to ask yourself a few simple but important questions. These usually point you in the right direction without much back and forth:
1. What span do I really need, and am I okay with interior columns?
You know your project better than anyone. How big does it need to be, and do you need wide open space?
2. What am I storing or housing?
Knowing how you intend to use the space and the average size of what you’re storing makes a big difference in what style structure you go with.
3. What are my local wind, snow, and seismic requirements?
Your building will need to comply with ASCE 7 standards and local building code requirements for wind, snow, and earthquake potential. The Building Specialists and Direct Metal Structures will be able to tell you what is required in your area.
4. Do I need to support lighting, ceilings, fire sprinklers, or overhead doors?
Having a good grasp of this will help you pick a truss system that coincides with your design.
5. What insulation and interior finish do I plan to use?
The finishing details matter and will depend on the type of structure you use. If you’d like to know more about insulating your building, check out our handy.

FAQs About Truss Systems
Do you have questions about metal building trusses? Below, we’ve answered some of the ones we see on a regular basis:
1. What is the difference between a metal building truss and a rigid frame?
Answer: A truss uses smaller members arranged in a web; a rigid frame uses large welded beams built for heavier loads and wider spans.
2. How far can a metal building truss span without interior columns?
Answer: Most land between 20' and 60'+, while clear-span systems can run past 100' in the right conditions.
3. Are truss-style metal buildings cheaper than rigid-frame buildings?
Answer: Not always. Trusses may use less steel, but rigid frames can be more cost-efficient in bigger, taller projects.
4. How do snow and wind loads affect the truss or frame I need?
Answer: Higher loads require stronger designs, different spacing, or sometimes a completely different framing type.
5. Can I use a span chart to plan my own truss?
Answer: No, those charts are only for reference. Real trusses must be engineered for your location and intended use.
