At Simpson Steel Building Company, we make New Hampshire projects straightforward and budget-wise. Whether you’re planning a metal building for storage or a steel building for light commercial use, we guide you from specs to shipment with practical options and clear communication. Our patented truss system creates open interiors with fewer pieces, while our team keeps your project moving—without surprises. Each metal building kit is engineered to your ZIP code and intended use. Our truss frame limits are 50 feet wide and 18 feet eave height for non-extreme loads; when you need more capacity, we’ll price a rigid steel building and outline the trade-offs in span, height, and cost. Add doors, windows, insulation, color roofs, gutters, and more for a solution that fits your site and schedule.
Engineered Kits for New Hampshire
Accurate pricing starts with good details. Share your dimensions, eave height, ZIP code, framed openings, endwall style, and accessories. Our truss design derives strength from geometry rather than heavy I-beams, often saving money compared with similar rigid frames. Manuals, drawings, and pre-punched parts help your crew assemble efficiently, while our phone support answers real-time questions. Let’s turn your plan into a kit that installs smoothly and performs for years. Prefer to talk it through? Contact us, give us a call. Ready now? Use the quote form. Just exploring?

Simpson Steel Building Company has been providing metal buildings in New Hampshire for over 40 years. The majority of steel buildings we provide in New Hampshire are used for agricultural purposes, grow houses, garages and shops, and residential houses. Simpson provides complete engineered plans, engineered design calculations, and even engineered foundation plans by a licensed New Hampshire engineer that you will need to obtain your building permit.
New Hampshire building permits can be very strict. While we do have a licensed engineer to stamp all of our plans, we still rely on our customers verifying all of their snow load, wind load and seismic category requirements. Getting a permit for a metal building in New Hampshire can feel overwhelming at times. Simpson’s building kits have never been denied a permit in the state of New Hampshire. While we do not obtain your permit for you, we are prepared to help guide you with our experience.
Simpson offers 18” roof overhangs for our building packages. These can be a very important addition in New Hampshire, particularly in areas with higher than normal snow load requirements. Adding overhangs to you buildings roofs not only enhance the buildings looks, they also help push any snow that is falling off the roof away from the buildings doors and foundation. Some building owners will use gutters & downspouts, others believe that the snow can break the gutters off too easily and elect to go with the overhangs. We also provide insulation packages of 3”, 4” and 6” thicknesses. Adding insulation to your building will help with climate control and will also help reduce any kind of condensation build up during the hotter months. This will be key to protecting your personal belongings and valuable items that you are storing.

Frequently Asked Questions
How do sloped or rocky parcels affect the foundation plan?
- Steep sites often favor piers or a stem-wall perimeter to manage grade changes, frost depth, and access. Your package includes anchor locations and reactions, which your concrete contractor uses to place bolts accurately and set thresholds. Plan drainage, compaction, and finished floor elevation early to protect the building and maintain door performance.
What documents are included for approvals and installers?
- You’ll receive engineered drawings, an anchor-bolt plan, design load data, and an erection manual, plus a packing list for receiving. Many jurisdictions accept these documents for permit review; always confirm local submittal rules, inspections, and setbacks. If your authority needs revisions within truss limits, we’ll coordinate updated engineering.
Can I insulate now and finish interiors later?
- Yes. Start with radiant barrier or vinyl-faced fiberglass and add liner panels when you’re ready, keeping penetrations sealed to control moisture. Coordinate electrical and mechanical routes before closing cavities, and include ridge or gable vents to balance airflow, comfort, and long-term durability.
How do New Hampshire winters affect design choices?
- Snow and wind criteria vary by municipality and elevation, so we engineer to your ZIP code rather than guess. Proper insulation, air sealing, and venting reduce condensation in cold snaps, protecting contents and finishes. If your loads exceed truss limits, we’ll recommend a rigid option and explain cost and schedule implications.
Can I prepare the site before ordering?
- Yes, but coordinate early. Verify setbacks, utilities, and drainage, and discuss slab, piers, or stem-wall options with your concrete contractor. Share your plan with us so anchor layouts, door thresholds, and finished floor elevation align with the building package.
What if I need help with assembly?
- Many owners self-erect using standard equipment and our manuals. If you prefer speed or turnkey convenience, hire a local erector experienced with pre-engineered kits. Staging parts by sequence, checking weather windows, and scheduling inspections in advance keeps the build on track.
