Customize & Build Your 70×40 Metal Building Online

Every option below is selectable in our free 3D builder or your custom commercial quote. The 70′ x 40′ footprint stays the same. Roof style, leg height, gauge, doors, windows, colors, insulation, certification, and interior layout are all configurable.

Leg Height (12′ to 20’+)

The 70×40 footprint gives you 2,800 sq ft of open space. Leg heights typically start around 12′ for storage and garage use, 14′ to 16′ for fleet and RV access, and 18′ to 20’+ for commercial, agricultural, forklift, or overhead equipment clearance.

3 Roof Styles

Regular Roof is available only where approved for simpler shelter packages. A-Frame Horizontal gives a traditional peaked look. Vertical Roof is the recommended roof system for 70×40 buildings because vertical panels move rain, snow, and debris off the eaves more efficiently.

Roof Pitch & Slope

Standard 3:12 or 4:12 pitch depending on the engineered package. Upgrade to 5:12 or 6:12 pitch for heavy snow regions, steeper aesthetics, or roofline matching with an existing commercial or agricultural structure.

Frame Gauge (14, 12, or Red Iron)

12-gauge framing is commonly specified for 70×40 commercial and agricultural structures. 14-gauge may be available for lighter-duty packages where approved. Red iron primary framing is available for cranes, mezzanines, rooftop loads, and industrial point loads.

Sheet Metal Gauge (29 or 26)

29-gauge sheet metal panels are standard on many tubular-frame builds. Upgrade to 26-gauge for commercial durability, high-wind exposure, hail-prone regions, coastal climates, or heavy-use agricultural sites.

Certification & Engineering

Certified 70×40 buildings include stamped engineered drawings, wind and snow calculations, foundation plans, and anchor layouts matched to your local code. Certification is recommended for most commercial, agricultural, and permitted residential shop projects.

Roll-Up Garage Doors

Roll-up garage doors from 8’x8′ up to 16’x16′ are available. Fleet garages often use multiple 12’x12′ or 14’x14′ doors along the 70-foot wall. RV and equipment storage packages can use 14′ to 16′ tall doors for clearance.

Walk-In Doors

36″ personnel doors and 4’x7′ commercial walk-in doors are available with full frames, weatherstripping, and locksets. Place doors on sidewalls or endwalls to match workflow, emergency exits, or office access.

Hydraulic & Rapid Doors

Hydraulic one-piece doors, high-speed rapid-roll doors, and commercial opener systems are available for high-cycle businesses, equipment shops, fleet operations, and warehouse access points.

Windows & Skylights

30″x30″, 36″x36″, and 48″x48″ windows are available, along with skylights, clerestory bands, and storefront-style glazing for commercial-facing builds. Insulated glazing helps with comfort and energy performance.

Framed Openings

Order framed openings for future dock doors, office entries, HVAC penetrations, fans, vents, louvers, or expansion. Planning openings before fabrication prevents costly field cutting later.

Garage Door Openers & Windows

Commercial chain-hoist, jackshaft, smart Wi-Fi, and high-cycle opener systems are available. Window kits in roll-up doors add daylight while preserving a secure exterior shell.

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. All colors are available for roof, walls, and trim.

Mix-and-Match Roof, Walls, Trim

Pick a different color for roof, wall panels, and trim. Popular 70×40 combinations include Galvalume roof with Pewter Gray walls, White walls with Barn Red trim, or Burnished Slate walls with Black trim for commercial curb appeal.

Wainscoting (Two-Tone Walls)

Wainscoting on a 70×40 building gives the lower wall section a contrasting color. It improves curb appeal, hides dock-side scuffs, and helps match an existing shop, barn, dealership, or municipal building.

Galvalume (Bare Metal Finish)

Galvalume is a hot-dipped aluminum-zinc coating with no paint. It is cost-effective, corrosion-resistant, and popular for agricultural, industrial, and rural commercial buildings.

Painted Trim & Flashings

Color-matched ridge caps, eave trim, rake trim, gable trim, corner trim, and framed opening trim ship with your selected package. Color-coded screws give the exterior a clean finished look.

Custom Color Match

Need to match an existing building, corporate brand, HOA requirement, or municipal color palette? Custom paint matching is available for an upcharge with sample review before final order approval.

Insulation Options

Choose single-bubble radiant barrier, double-bubble insulation, fiberglass batt, spray foam, insulated metal panels, or vapor barrier systems. Insulation is recommended for offices, workshops, gyms, warehouses, and any 70×40 building with HVAC.

Lean-To Additions

Add lean-tos along one or both sidewalls for extra covered storage, outdoor work zones, trailer staging, livestock shade, or material protection without changing the primary 2,800 sq ft footprint.

Mezzanines & Lofts

Mezzanines and partial lofts can add overhead storage, parts rooms, office platforms, or mechanical areas. Red iron and engineered framing upgrades are recommended for mezzanine loads.

Interior Partitions

Divide the 2,800 sq ft interior into shop bays, offices, restrooms, inventory rooms, mechanical spaces, wash areas, or storage zones. Steel-stud partitions and insulated interior panel options are available.

Trim, Anchors, Gables

Decorative trim, gable accents, framed entry packages, and contrasting corner trim can make a 70×40 building look more finished for customer-facing or residential-adjacent sites.

Flooring Prep

We do not pour foundations, but we guide you on slab specifications. A 70×40 often uses a reinforced concrete slab for enclosed commercial, garage, warehouse, or equipment use. Gravel or compacted surfaces may work for open shelters where approved.

Wind & Snow Certification

Standard packages commonly support 115 to 140 MPH wind and 35 to 40 PSF snow load depending on configuration. Certified upgrades are available up to 170+ MPH wind and 65+ PSF snow load for harsh climates.

Permit-Ready Drawings

Stamped engineered drawings, foundation plans, wind and snow calculations, and anchor layouts are available for county permits, commercial approvals, insurance, and HOA or municipal review.

Door Locks & Access Control

Slide bolts, deadbolts, keypad entry, smart locks, commercial access control, badge readers, and Wi-Fi connected garage door openers are available for fleet, inventory, and equipment security.

Fire Safety & Alarms

Smoke and heat detection, emergency lighting, exit signage, Class ABC extinguishers, fire-rated partitions, and sprinkler-ready framing can be specified for commercial or institutional 70×40 use.

Anchoring System

Concrete wedge anchors, asphalt anchors, mobile-home anchors, auger ground anchors, or engineered anchor bolt systems are matched to the foundation and local wind/seismic requirements.

Solar & Roof-Top Loads

Reinforced roof framing can support solar panels, HVAC condensers, exhaust fans, skylights, antenna systems, and other rooftop loads when specified before fabrication.

70×40 Metal Building Codes, Permits & Engineering

Every 70×40 prefab steel building we sell can be engineered, stamped, and certified to meet your local building codes. Certification is strongly recommended for commercial, agricultural, fleet, warehouse, industrial, and permitted residential shop builds.

IBC/IRC
Minimum construction standards for building codes
NEC
Electrical safety to reduce fire and shock risk
IFGC
Safe operation of fuel gas appliances and equipment
IECC
Energy efficiency and conservation requirements
IMC
HVAC, ventilation, and exhaust system standards

We also adhere to plumbing codes, energy conservation standards, ADA requirements when applicable, and any state or local requirements. Our team handles code compliance so you have total peace of mind.

How to Maintain a 70×40 Metal Building

Routine maintenance keeps your 2,800 sq ft prefab steel building weather-tight, structurally sound, and looking sharp through the full 20-year rust-through warranty period.

1
Clean Roofing & Siding
Wash roof and wall panels twice a year to remove dirt, pollen, leaves, salt residue, and industrial dust. A 70×40 exterior may benefit from a pressure washer or professional wash crew.
2
Inspect Caulking & Seals
Check sealant around doors, windows, framed openings, vents, roof penetrations, and panel laps. Reapply sealant where gaps or cracking appear.
3
Check Connections
Inspect anchor bolts, frame connections, braces, door tracks, fasteners, and hardware after major storms and during scheduled facility walks.
4
Touch Up Paint & Coatings
Touch up scratches, forklift scuffs, mower marks, dock-side dings, and lower wall panel damage with matching paint before exposed metal corrodes.
5
Lubricate Doors & Locks
Lubricate roll-up door rollers, hinges, tracks, opener chains, personnel door hinges, lock cylinders, and commercial door hardware quarterly on high-cycle buildings.
6
Gutter & Pest Control
Clear gutters and downspouts if installed. Watch for birds, rodents, wasps, and pests around eaves, stored material, feed areas, and dock or door openings.

How Much Does a 70×40 Metal Building Cost?

No hidden fees on any 70×40 prefab steel building. A 70×40 open shelter starts around $24,500, an enclosed equipment building from $32,500, a fleet garage from $36,500, and a commercial or industrial certified build with heavier framing, large doors, and insulation can reach $82,000+. Add foundation prep based on slab, soil, code, and use requirements for the complete project cost.

Building Configuration

An open 70×40 shelter is the lowest-cost option. Fully enclosed warehouse, fleet garage, shop, or industrial configurations add wall panels, doors, framing upgrades, insulation, trim, and engineering.

Your Location

Delivery distance, regional labor rates, wind zone, snow load, seismic requirements, state-specific code rules, and permit requirements affect the final 70×40 price.

Steel Gauge

12-gauge framing is commonly recommended for 70×40 buildings. Red iron upgrades cost more but are important for overhead cranes, mezzanines, heavy equipment loads, and high-cycle industrial use.

Roof Style & Pitch

Vertical Roof is recommended for most 70×40 buildings and may be required for engineered commercial packages. Higher pitch, standing-seam panels, or cool-roof coatings add cost but improve performance.

Certification

Certified buildings with engineered, stamped drawings cost more but are recommended for most 2,800 sq ft commercial, agricultural, industrial, and permitted residential shop structures.

Doors, Windows, Insulation

Large roll-up doors, commercial walk-ins, dock openings, storefront glazing, windows, insulation packages, openers, and ventilation systems can significantly change the final price.

70×40 Metal Building Complete Price Range

$24,500to$82,000+

Range covers an open shelter at the low end through a fully enclosed certified commercial or industrial build with 12-gauge or red iron upgrades, insulation, multiple large doors, windows, and engineered drawings at the high end. Reservation deposit typically ranges from 10% to 30% depending on your state and manufacturer. Remaining balance is due only after installation is complete.

70×40 Metal Building FAQ: Cost, Permits, Sizes & Install

Everything you need to know before ordering your custom 2,800 sq ft prefab steel building. Get answers on pricing, configurations, leg heights, roof styles, 17 color options, foundation prep, and code compliance.

A 70×40 metal building costs between $24,500 and $82,000+ depending on configuration. An open 70×40 shelter starts around $24,500, an enclosed warehouse or equipment building from $32,500, a fleet garage from $36,500, and a heavily engineered commercial or industrial build with red iron, insulation, large doors, and stamped drawings can exceed $82,000. Final price depends on roof style, frame gauge, door package, insulation, certification, location, and foundation requirements.

A 70×40 prefab steel building provides 2,800 square feet of covered or enclosed space. It works well as a commercial warehouse, fleet garage, equipment storage building, agricultural barn, contractor shop, RV and boat storage building, light manufacturing shop, maintenance facility, indoor training area, municipal storage building, or large residential garage and workshop.

Leg heights for a 70×40 steel building typically range from 12 feet to 20+ feet. Storage and garage layouts often use 12 to 14 feet. Fleet garages, RV storage, and equipment buildings commonly use 14 to 18 feet. Industrial, agricultural, and forklift-access buildings may use 18 to 20+ feet for overhead clearance. Roof peak height adds additional clearance depending on roof pitch.

We offer Regular Roof, A-Frame Horizontal / Boxed Eave, and Vertical Roof options. For a 70×40 building, Vertical Roof is the recommended system because it routes water, snow, and debris toward the eaves. Standard pitch is usually 3:12 or 4:12 depending on engineering, with 5:12 and 6:12 upgrades available for snow regions and steeper aesthetics.

Choose from 17 standard color options for your roof, walls, and trim independently: 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. You can also mix and match colors for roof, walls, trim, and wainscoting.

Most areas require a building permit for a 70×40 metal building because it provides 2,800 square feet of floor space. We supply certified buildings with engineered, stamped drawings that meet IBC, IRC, NEC, IFGC, IECC, and IMC codes. Your building advisor can help you understand what your county, city, or state requires before you order.

Free delivery is included on every 70×40 metal building order in 48 states. Free professional installation is included on many tubular-frame 70×40 buildings. Red iron commercial builds, dock-equipped buildings, insulated metal panel packages, complex door arrays, or heavily engineered structures may carry a separate installation fee depending on location and scope.

A 70×40 prefab steel building can be installed on concrete, asphalt, gravel, or level dirt depending on the configuration, but reinforced concrete is recommended for fully enclosed warehouses, fleet garages, commercial shops, and equipment buildings. Engineered foundations may be required for certified commercial buildings, red iron packages, heavy equipment, mezzanines, or high wind and snow ratings.

Standard 70×40 steel buildings commonly support 115 to 140 MPH wind ratings and 35 to 40 PSF snow load depending on configuration. Certified upgrades can engineer the structure for 170+ MPH winds in hurricane and coastal zones and 65+ PSF snow loads in mountain, northern, and heavy snow regions. Final ratings depend on your local code and selected engineering package.

Yes. A 70×40 metal building can be engineered for forklifts, lifts, machinery, equipment maintenance, manufacturing, rooftop HVAC, mezzanines, and some crane-ready applications. Heavy machinery projects should use 12-gauge or red iron framing, reinforced foundation design, and certified engineering matched to the equipment loads.

Our 70×40 metal buildings can be engineered to comply with IBC and IRC Building Codes, NEC Electrical Code, IFGC Fuel Gas Code, International Energy Conservation Code (IECC), and International Mechanical Code (IMC). We also meet plumbing codes, ADA requirements, energy conservation standards, and applicable state or local requirements when specified. Stamped engineering plans are available with every certified build.
