Established in 1964, Daybar began manufacturing steel frames during a period of extremely strong construction activity in Canada. Operating from a small facility located outside of Toronto, Daybar sold these frames directly to local contractors in the surrounding area. Daybar's Head Office As the demand for building products remained strong throughout the 1970's, Daybar expanded into a larger facility located in Brampton, Ontario. It was at this new location that Daybar first produced hollow metal doors to sell with their metal frames. During this period, Daybar began to earn a reputation for producing quality products amongst its growing customer base of local contractors and building owners.  As the use of zinc coated steel began to dominate the Canadian automotive industry in the late 1970's, Daybar followed this trend by changing the base material for their steel doors and frames from cold rolled steel to a zinc iron alloy galvanneal steel. The added rust protection of this product was immediately recognised by Daybar's customers and within a few years, galvanneal became the standard material used for steel doors and frames produced in Canada.
