Engineering News-Record (ENR) recently released its “Top 600 Specialty Contractors” list, which includes the largest revenue-generating glazing and curtainwall firms in the country.
Revenue for the top ten firms in the glazing and curtainwall category totaled $1.46 billion, nearly the same as last year’s total of $1.45 billion.
Enclos topped the list for the third consecutive year, but fell in the overall rankings from No. 56 to No. 79 with a total 2018 revenue of $332.9 million. In 2017 the company was ranked No. 39 overall. Harmon was second on the list this year after being unranked last year. The company ranked No. 100 overall with a 2018 revenue of $284.2 million.
More than half of the glazing firms that made ENR’s Top 600 Specialty Contractors list dropped in the overall rankings compared to the 2018 edition, while two increased in overall rank and two were not ranked last year. This could be due to not having had a high enough revenue or because the company did not provide its information for review.
