We measure the opening, confirm headroom and side room, and identify the slat profile, cycle demand, wind load, and insulation needs.
New doors are specified by gauge, slat profile, finish, operation type, and operator, with lead time listed on the quote.
Guides are anchored to the jambs, the barrel and brackets set, the curtain hung and tensioned, and the hood, hoist or operator installed.
On existing doors we replace slats, bottom bars, springs, guides, and hardware and re-tension the counterbalance.
The door is cycled, limits set, and photo eyes and sensing edges verified on motorized doors.
Ask for the equipment specification, installation work, compatible operating and safety devices, site preparation responsibilities, and any lead-time or access constraints. Requirements depend on the actual opening.
