About Us

About IG Masonry Support

Founded in 1958, IG is a division of Europe’s largest manufacturer of steel lintels and masonry support systems. The major activity of IG is the design, development, manufacture and supply of standard and custom made masonry support. IG’s extended range of building components includes Brick Slip Feature Lintels, Steel Support Systems and Windposts.

The company operates from three major depots. The headquarters and place of our origin, remains in Cwmbran, South Wales. IG has large manufacturing facilities in Swadlincote South Derbyshire, and Cookstown.

IG invented the original open back lintel in 1967, which has now become the industry standard. Our lintels are engineered to be the most structurally and thermally efficient lintels available. They are widely specified and used throughout Europe on commercial, industrial, residential and institutional projects.

Combining optimum performance with design flexibility, IG Masonry Support offers masonry support solutions, which are easy to install, as well as revolutionary brick slip systems that radically reduce onsite labour.

Today’s rapidly changing regulations call for innovative thinking on construction methods.  To meet the demand IG Masonry Support provides architects, engineers and specifiers with an expert partnership for key structural components.   With knowledge of our customers’ ever changing needs, we continually invest in specialist plant and equipment. IG also invests in professional training for employees to support and manage the business.
