Helping build the Pacific Northwest
Since 1950 Colorado Steel Sash has been distributing products, tools, and consumables to professional contractors building the great Pacific Northwest. We specialize in products geared towards the waterproofing and glazing industry and take great pride in distributing premium quality American made products wherever possible.
Locally Owned and Operated
Colorado Steel Sash is a family owned business with headquarters in Seattle’s Georgetown neighborhood. We love the Pacific Northwest and are committed to providing only the best products and honest services to our partner contractors in Washington and Oregon.

Our Seattle warehouse is open 6 days a week and our Oregon warehouse is open 5 days a week for product selection and pickup. We cater to the professional installer and contractor by providing fast in-and-out pickup, accurate product lead times, and a wealth of industry and product knowledge.
