Curtain wall price in Karaj — approximate Aban 1405 (Oct–Nov 2026) rates
Karaj and its surrounding towns (Mehrshahr, Fardis, Andisheh) are close to Tehran; the price difference from Tehran is usually small and crew commuting is easy. In Aban 1405, complete installation is the same roughly 6.5 to 18.5 million Toman per m².
All prices are approximate, based on the company's supply rates (Namakaran Fakher Engineering Co.) and the Aban 1405 (Oct–Nov 2026) survey, with Tehran as the base; all rates exclude VAT. Daily material prices change and a firm figure is issued only with a detailed estimate for your project — all numbers must be re-confirmed at contract time.
Karaj's key technical issue is wind. At height, wind load and the wind-bracing detail must be engineered seriously; this affects the amount of profile and fixings. A pro-forma that ignores Karaj wind is cheaper, but it is not correct.
