Interior black-framed metal and glass door

Steel Doors in New York.

Design-forward black-framed steel and glass doors and room dividers for New York lofts, brownstones, and pre-war conversions, sized to an opening that was almost never built square.

In short

The black steel factory-window look that defines a Tribeca or SoHo loft was never built with a thermal break, and a literal copy of it fogs and sweats on the inside face by January. Crateworks builds a true thermal break into that same profile, or swaps to aluminum for the identical sightline with no upkeep at all.

Built for New York’s climate

New York's real winter is the design problem here, more than moisture. A steel frame without a genuine thermal break conducts cold straight through, which shows up as condensation or frost on the interior face on the coldest nights, the same failure a lot of original loft factory sash actually has. A true thermal break closes that gap while keeping the black steel sightline people are buying the look for. Where a facade-facing replacement sits in a historic or landmarks district, that review can set requirements on the exterior profile, confirm locally before ordering. Interior use, a room divider, a pantry door, needs none of that and no special coating.

Why it suits New York

The sightline is usually the whole reason someone wants this door, slim black frames around a wall of glass, whether it is facing the street or dividing a loft. Because sourcing runs factory-direct, an oversized opening or an unusual mullion pattern is priced as a spec change here, not a special-order premium. Give us the opening dimensions and glazing pattern through /brief, from a single pair to a full steel-and-glass wall.

Common questions

Not with a genuine thermal break, which is what separates this from an authentic but drafty original factory sash. We build the break into the same black steel profile so the sightline survives without the condensation.
That is the point of the thermal break, or we can spec aluminum in the same profile if zero coating upkeep matters more than the material being true steel.
It can, if the building sits in a historic or landmarks district. Confirm locally before ordering, and we will build to whatever profile that review requires.
That is the default here. Height, width, and mullion pattern are quoted to your exact opening through /brief, not pulled from a stock size.
