Steel Accordion Doors

Both accordion and bifold doors fold, but they handle different opening sizes. Bifolds stack to one end (or split to both ends); accordions use more leaves (6, 8, 10+) and fold tighter, handling wider openings.

Where they excel

• Indoor-outdoor living spaces 14–40 feet wide
• Restaurants and event spaces that need fully open during service, fully closed after hours
• Pool houses with oversized openings
• Commercial storefronts

Build specs

• 6 to 14 panels, each 18″ – 36″ wide
• Top-hung track, usually concealed in a pocket above the opening
• Bottom guide pin on each panel
• Panels stack to ~6–8″ depth when folded against a wall

Glass and frame

Full-height insulated low-E glass per panel. Frame is 14-gauge welded steel. For truly oversized walls we reinforce with concealed structural steel in the header.

Weather sealing

With 6–14 meeting stiles, we use a dual-brush seal at every joint plus a compression drop seal at the sill. Tested to the same 50 mph wind-driven rain standard as our sliding systems.

Lead time

Accordion systems are custom-engineered per opening — expect 10–14 weeks. Install is a 2–3 day job with a crew of three.
