Качество оцинковки хорошее, не ржавеет. С осевым вентилятором работает отлично, поток воздуха норм. В целом доволен покупкой.

Норм труба, для промышленной вытяжки самое то. Доставили быстро, но один стык пришлось чуть подправить.

Заказывали из нержавейки под индивидуальный размер. Все четко подошло, металл плотный, швы ровные. Рекомендую!
