70 years of building Seattle
Since 1950 Colorado Steel Sash has been distributing products, tools and consumables to the professional glaziers who are building Seattle and the rest of the Puget Sound. We also distribute products to the waterproofing and coatings industry, and have expanded coverage in Oregon with our Portland warehouse and staff.
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.
Warehouse & Will Call
Our Seattle and Oregon warehouses are open 6 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. Although we specialize in serving contractors, we are open to the general public.
