All Size Perforating Ltd. is an exclusive manufacturer of grain drying equipment for new and existing bins in full round flooring or partial aeration systems. A family operated manufacturing business founded in 1978 by the late Peter P. Friesen (1937-1999) in Winkler, Manitoba, Canada.

In the early stages of the business, there were many trial and error periods where the focus was on customizing various screen sizes, hence the name All Size Perforating Ltd. It was realized that the perforating idea might have potential in the agricultural market for aeration purposes. This was the venture that helped the business in becoming a corporation in 1981. The competition became tough and in 1984 All Size Perforating Ltd. almost faced bankruptcy. Product innovations came underway. It seemed to be the V-Cross Duct system was the all time favorite among farmers in 1985. It was peddled to farmers looking for the "cheapest most economical" system together with All Size Perforating Ltd.'s own Adventer Fan. This is what boosted the sales figures to keep the business alive. It was then that the latest state of the art technology was put into product that proved our aeration floor to be one of the strongest in the market. Expansion is taking place today in providing the market with manufacturing our own perforating screening, as was the original intent, and distribution of various sizes sheets and screens.
