Common questions from Hobby & Project Space shoppers.
The questions our team hears every week. Click any to expand the short answer.
How thick is the steel on a Steel and Stud 20×40 metal building?
Standard frame: 14-gauge (1.5 mm) galvanized tubing. Optional 12-gauge upgrade (2.5 mm) for high-wind/snow zones. Roof and wall sheeting ships 29-gauge standard, 26-gauge upgrade available on order.
Does Steel and Stud deliver and install in my state?
Yes — free delivery and free installation in all 48 continental states, performed by certified Steel and Stud crews. Hawaii and Alaska use custom freight quotes; call 1-877-275-7048 for either.
What's the typical lead time for a 20×40 building?
Standard: 3–5 weeks from order confirmation to install completion. Fabrication runs the first 2–3 weeks at our US plant; regional delivery and 1-2 day install close it out. Rush builds available for $345.
Can I finance a Steel and Stud building without a credit check?
Yes — Steel and Stud's rent-to-own partner does not pull credit. Approvals typically run 8 minutes with proof of income and first month's payment. 36–60 month terms, no early-payoff penalty.
What's covered under the 20-year warranty?
Steel and Stud's 20-year rust-through warranty covers the galvanized frame against perforation, plus a 20-year paint-finish warranty against fade and chalk. Workmanship on the install is warrantied for 1 year. Warranty transfers to the next owner on resale.

Hobby & Project Space questions, answered.
What's included in the $11,800 hobby spec?
Hobby-spec uplift over base adds R-13 wall insulation, R-19 ceiling insulation, 5/8 Type-X drywall pre-cut, two 36×36 windows, and a walk-in personnel door.
Realistic finish-out cost for a man cave?
Plan $8,000 to $18,000 in finish trades: drywall + paint $3,000-$6,000, flooring (LVP/rubber mat) $1,500-$4,000, and the balance on the finish trades you hire yourself. Move-in-ready in 4-6 weeks after shell.
Do I need a permit for a hobby building?
Most counties exempt accessory buildings under 1,000 sq ft from full permits but require a 'shed permit' filing. Your building ships with stamped engineered drawings to file with the county.
What colors and warranty come with the building?
Choose from the standard color range on roof, walls, and trim at no extra cost. The building carries a 20-year rust-through warranty on the panels and a certified wind + snow rating for your county.
How loud will my home gym be to the neighbors?
R-13 insulation + drywall + the vertical-roof panel pattern drops interior reverberation by ~12-15 dB. For deadlift drops or amplified music, add a 1-inch acoustic panel layer on the wall facing the neighbor (~$0.80/sqft).
