Quinn Building Supplies

Established in 1978 and headquartered in Dungannon, County Tyrone, Northern Ireland, Quinn Building Supplies is a family-owned builders’ merchant and engineered timber specialist serving trade and DIY customers across Ireland and the UK. From its origins as a local building materials supplier, the company has expanded to become a comprehensive provider of construction materials and timber engineering solutions.

Quinn’s extensive product range includes structural timber, engineered roof trusses and open web joists, internal doors, mouldings, groundworks and sub-floor materials, paint and decorating supplies, drainage and hardware. These are supported by value-added services such as machining, priming and pre-finishing to meet project-specific requirements.

In 1993, the business expanded into the design and manufacture of timber roof trusses, integrating advanced CAD technology to deliver engineered components to exact specifications. With a long-standing reputation for quality materials, technical expertise and dependable service, Quinn Building Supplies continues to build steadily on its heritage while supporting modern, efficient and sustainable construction projects.
