Customize & Build Your 70×50 Metal Building Online
Every option below is selectable in our free 3D builder or your custom quote. The 70′ x 50′ footprint stays fixed. Roof style, leg height, gauge, doors, windows, color, insulation, engineering, and finish details are yours to choose.
Leg Height (12′ to 20’+)
The 70×50 footprint works well with 12′ to 20’+ leg heights. Warehouses and garages often use 14′ to 16′. RV and equipment storage usually lands at 16′ to 18′. Manufacturing, agricultural, and fleet buildings may use 18′ to 20’+ for high clearance.
3 Roof Styles
Vertical Roof is recommended for every 70×50 build because water and snow need to move efficiently off the larger roof surface. A-Frame Horizontal is available for aesthetic builds. Regular Roof is not recommended for this footprint.
Roof Pitch & Slope
Standard 4:12 roof pitch works for most 70×50 buildings. Upgrade to 5:12 or 6:12 for snow regions, mountain sites, or architectural matching. Cool roof coatings and standing-seam options are available for commercial applications.
Frame Gauge & Red Iron
12-gauge galvanized tubing is recommended at this scale. Red iron primary framing is available for heavy industrial loads, mezzanines, rooftop HVAC, overhead doors, and long-term commercial use.
Sheet Metal Gauge
26-gauge sheet metal panels are recommended for 70×50 roof and wall systems. Upgrade to insulated metal panels for conditioned commercial spaces, offices, gyms, retail areas, or climate-controlled storage.
Certification & Engineering
Certified engineering is recommended and often required for 3,500 sq ft buildings. Stamped drawings, foundation plans, anchor layouts, and wind/snow calculations can be matched to your local building department.
Roll-Up Garage Doors
Roll-up doors from 10’x10′ to 16’x16′ are available. Fleet garages can use multiple doors along the 70′ side. Agricultural buildings can use oversized door openings for tractors, implements, and loaded trailers.
Walk-In Doors
36″ personnel doors and 4’x7′ commercial doors are available with frames, weatherstripping, and locksets. Add multiple entries for warehouses, shops, offices, and emergency egress.
Hydraulic & Rapid Doors
Hydraulic one-piece doors, high-speed rapid-roll doors, and commercial overhead systems are available for high-cycle fleet, warehouse, agricultural, and industrial applications.
Windows & Skylights
30″x30″, 36″x36″, 48″x48″, storefront glass, clerestory windows, and skylights add natural light for workshops, showrooms, offices, and athletic spaces.
Framed Openings
Order framed openings for future doors, windows, dock equipment, exhaust fans, HVAC penetrations, storefront glass, or side-wall expansion. Framing during fabrication is cleaner than cutting later.
Openers & Access
Commercial chain-hoist, motorized, and Wi-Fi-enabled openers can be paired with keypad entry, badge access, smart locks, and fleet-management access systems.
17 Standard Color Options
Choose from Barn Red, Beige, Black, Brown, Burgundy, Burnished Slate, Clay, Galvalume, Green, Patriot Red, Pewter Gray, Quaker Gray, Rawhide Tan, Royal Blue, Sandstone, Slate Blue, and White.
Mix-and-Match Roof, Walls, Trim
Pick a different color for roof, walls, and trim. Popular commercial combinations include Galvalume roof with Pewter Gray walls, Black trim, or brand-colored wall panels for showrooms and municipal projects.
Wainscoting
Two-tone lower wall panels add curb appeal and protect high-contact areas around loading zones, equipment storage, and customer-facing entries.
Galvalume Finish
Galvalume is a hot-dipped aluminum-zinc coating with no paint. It is cost-effective, corrosion-resistant, and works well for agricultural, industrial, and rural commercial buildings.
Painted Trim & Flashings
Color-matched ridge caps, eave trim, gable trim, corner trim, and rake trim ship with the building package. Color-coded screws match your chosen panel colors.
Custom Color Match
Custom color matching is available for corporate branding, HOA requirements, municipal standards, or matching existing barns, warehouses, and commercial buildings.
Insulation Options
Choose single-bubble radiant barrier, double-bubble, fiberglass batt, spray foam, or insulated metal panels. Conditioned shops, warehouses, gyms, and showrooms benefit from higher R-value packages.
Lean-To Additions
Add lean-tos along one or both sides for trailer staging, equipment parking, hay storage, covered work areas, outdoor inventory, or livestock shade.
Mezzanines & Lofts
Mezzanines can create parts storage, office space, break rooms, or elevated inventory zones. Engineering is required to match live and dead load requirements.
Interior Partitions
Divide the 3,500 sq ft into warehouse bays, offices, restrooms, mechanical rooms, tack rooms, service bays, or secure storage rooms using steel-stud or insulated interior panels.
Trim, Anchors, Gables
Decorative gables, color trim, framed entries, and commercial fascia can give your 70×50 a finished look that fits a farm, showroom, shop, or municipal site.
Flooring Prep
We do not pour foundations, but we guide you on slab requirements. A 70×50 typically uses a reinforced concrete slab, thickened edges, and engineered footings depending on soil, loads, and building use.
Wind & Snow Certification
Standard wind and snow ratings vary by configuration and region. Certified upgrades are available up to 170+ MPH wind and 80+ PSF snow load for hurricane, coastal, mountain, and heavy snow zones.
Permit-Ready Drawings
Stamped engineered drawings, foundation plans, anchor schedules, and code calculations can be prepared for IBC, IRC, NEC, IFGC, IECC, IMC, and state-specific code requirements.
Locks & Access Control
Deadbolts, keypad entry, smart locks, badge readers, Wi-Fi openers, auto-lock systems, and commercial access controls are available for secure storage and fleet management.
Fire Safety & Alarms
Commercial builds can be configured for fire alarm systems, emergency exit signage, extinguishers, egress doors, occupancy separation, and sprinkler-ready framing where required.
Anchoring System
Concrete wedge anchors, embedded anchor bolts, asphalt anchors, mobile-home anchors, or auger anchors are matched to the foundation, wind exposure, and local code requirements.
Solar & Roof-Top Loads
Reinforced framing can support solar arrays, HVAC units, exhaust fans, satellite equipment, and rooftop mechanical systems when specified before fabrication.
70×50 Metal Building Codes, Permits & Engineering
Every 70×50 prefab steel building can be engineered, stamped, and certified to meet local building codes. Required for most commercial, agricultural, industrial, and municipal 3,500 sq ft structures, and recommended for large residential garages or storage buildings.
We also adhere to plumbing codes, energy conservation standards, ADA requirements where applicable, and any state or local requirements. Our team handles code compliance so your 70×50 building is permit-ready.

How Much Does a 70×50 Metal Building Cost?
No hidden fees on any 70×50 prefab steel building. A basic 70×50 open shelter starts around $28,500, enclosed agricultural and warehouse configurations start around $34,500, and fully certified commercial or red iron builds can reach $98,000+ depending on doors, insulation, engineering, and foundation requirements.
Building Configuration
An open 70×50 shelter is the lowest entry point. Enclosing the building adds wall panels, doors, trim, and labor. Commercial and industrial configurations add engineering, heavier framing, and code requirements.
Your Location
Delivery distance, regional labor rates, local permit requirements, wind exposure, snow load, and foundation expectations all affect the final 70×50 price.
Steel Gauge
12-gauge tubing is recommended at this footprint. Red iron upgrades add cost but are the right choice for heavy industrial loads, mezzanines, rooftop equipment, and long-term commercial use.
Roof Style & Pitch
Vertical Roof is recommended on 70×50 buildings. Pitch upgrades, standing-seam roofing, and cool roof coatings can increase cost but improve drainage, energy performance, and curb appeal.
Certification
Certified buildings with stamped engineered drawings cost more but are usually required for 3,500 sq ft commercial, agricultural, industrial, or municipal structures.
Doors, Windows, Insulation
Large roll-up doors, multiple walk-in doors, storefront glass, insulation, HVAC-ready framing, and commercial access systems can significantly affect the final 70×50 price.
70×50 Metal Building Complete Price Range
Range covers an open agricultural or equipment shelter at the low end through a fully enclosed, certified commercial build with heavy-gauge framing, multiple commercial doors, insulation, upgraded panels, and stamped engineered drawings at the high end.
