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 $13,250 hobby spec?
Hobby-spec uplift over base adds R-13 wall insulation, R-19 ceiling insulation, a 30A subpanel rough-in, an HVAC mini-split rough-in, 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, mini-split install $2,500-$3,500, lighting + outlets $1,000-$2,500. 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. Once you finish to drywall + electrical, you'll need an electrical permit pulled by your electrician.
Can I run a heat pump and TV?
Yes, the 30A subpanel handles a 12k BTU mini-split + a TV + LED lighting + occasional power-tool draw. For heavier loads (sauna, larger heat pump, electric vehicle charging), upgrade to the 60A subpanel rough-in (+$345).
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).
