Steel Fireplace Doors

Our steel doors use 7-gauge cold-rolled steel frames from Stoll Industries in Pennsylvania — roughly 3/16 inch thick. That's twice as heavy as economy-grade doors and rated to withstand the thermal stress of a 2,000°F house fire without warping.

For masonry fireplaces, yes. Steel weighs more, holds its frame straight under heat, and accepts powder coat at 400°F without distortion. Aluminum is lighter (better for some prefab applications) but warps faster under sustained heat and flexes at the welds.

Frames are sandblasted, primed, and powder-coated at 400°F in the factory — not painted. Powder coat bonds chemically to the metal and resists chipping, fading, and rust. We carry 21+ powder-coat finishes plus premium plated options like polished brass and antique copper.

Powder-coated steel doors don't rust under normal indoor use. Outdoor or screened-porch installations should specify our weather-rated coatings — humidity and salt air can degrade standard powder coat over 5-7 years. Inland indoor doors typically last 20+ years without rust.

A standard 36×26 overlap-fit steel door weighs roughly 45-60 lbs. Larger custom doors (42×32 and up) can hit 80-90 lbs. Plan for a second person during install — masonry doors need to be held flush to the brick while the first person marks anchor points.

Yes — vented gas logs require doors fully open during burn (any frame material). Vent-free gas logs require doors open at all times per code. Our steel doors meet UL and ANSI requirements for both. Confirm with your gas log manufacturer's install manual.
