BUILT FOR
BOULDER LIVING

Boulder demands more from its metalwork. The combination of intense UV at altitude, hard freeze-thaw cycles, and proximity to wildland open space means your fence, railing, or pergola needs to be built to a higher standard than most of the country.

We've been fabricating and installing custom steel and aluminum structures throughout Boulder since 2014 — from the historic bungalows on Mapleton Hill to the modern builds crawling up the Flatirons foothills. We understand Boulder's aesthetic, its permit requirements, and its climate.

No subcontracting. No templates. Everything is fabricated in our shop from raw steel or aluminum, then installed by the same crew that built it. That's how we guarantee the fit, the finish, and the longevity.

Colorado Wildfire Mitigation

METAL FENCING
NEAR OPEN SPACE

Homes along Boulder's Open Space & Mountain Parks boundary are in wildland-urban interface (WUI) zones — and wooden fencing acts as a fire ladder, carrying flames directly toward your home from adjacent grassland or forest.

Steel and aluminum fencing is non-combustible. It will not ignite from windblown embers, it will not contribute to flame spread, and it will still be standing after a wildfire passes through. For Boulder homeowners near open space in areas like Chautauqua, Shanahan Ridge, or Eldorado Springs Drive, metal fencing is one of the most impactful fire-mitigation investments available.

We can match virtually any aesthetic — modern flat-bar panels, decorative picket styles, solid privacy panels — in steel or aluminum with powder-coat finishes that last decades at altitude.

  • Non-combustible — won't ignite from embers
  • No flame-spread contribution unlike wood fencing
  • Eligible for fire-mitigation insurance discounts
  • 30–50+ year lifespan vs. 10–15 years for wood
  • Resistant to UV degradation at high altitude
  • No rotting, warping, or insect damage
  • Low maintenance — occasional cleaning only
  • Custom styles to meet Boulder design standards

WHAT THEY SAY

★★★★★

"We live on the south side of Boulder near the open space trail system and replacing our old cedar fence was long overdue. After the wildfires in our area we wanted something that wouldn't add to the fire risk. Oak & Iron walked us through all our options and built us a beautiful flat-bar steel fence with a matching gate. It looks clean and modern, the workmanship is impeccable, and we have genuine peace of mind now. Worth every penny."

BOULDER FAQ

Yes. We work throughout Boulder — North Boulder, South Boulder, Martin Acres, Newlands, Table Mesa, Mapleton Hill, and everywhere in between. We also serve properties in unincorporated Boulder County adjacent to the city.
The City of Boulder requires a building permit for most fences over 4 feet in the front yard or 6 feet in side/rear yards. Historic districts have additional design review requirements. We handle the permit process alongside you and have experience getting projects approved in complex situations.
It's not universally required, but strongly recommended for WUI properties. Boulder's OSMP borders create fire-interface conditions, and wooden fencing can act as an ignition pathway. Metal fencing is non-combustible, won't contribute to fire spread, and some insurance carriers offer discounts for non-combustible fencing in high-risk areas.

ALSO SERVING

We serve all of Boulder County and surrounding communities.
