Welcome to Lynden Door Canada!We manufacture insulated steel entry doors and have been doing so since 1985. Our business is built on a specialized product line and QUALITY, VALUE and SERVICE. We manufacture a wide range of products in both fire rated and non-rated versions.Our three distinct profiles and 20 distinct patterns suit virtually any design aesthetic. We specialize in fast delivery of custom sizes. Lynden Door realizes that not all door openings are made for ''standard'' sizes and so weve made it our business to deliver standard sizes and custom sized doors in 1/16'' dimension increments - fast and accurate. See our size grid in the online PDF Steel Door Brochure.For added SECURITY, we recommend the PROTEK door. PROTEK is an optionally available upgrade that takes the 24-gauge steel door you choose and heavily fortifies the internal structure to withstand break and enter attempts as well as the everyday hard-knocks that entry doors need to endure.Professional Grade Doors ?
