The steel lintel method has been developed and used in construction and brick buildings for centuries. It is a simple way to change the down force of the building specifically around an opening like a window or door and direction this force to the foundation below. In the case of a brick masonry wall , lintels may consist of reinforced brick masonry , brick masonry arches , precast concrete or structural steel shapes.

Keystone’s Parabolic Brick Feature Lintel comprises of a modified Parabolic Arch steel lintel with a box section on the outer leaf. The lintel is insulated in the cavity and spans from inner to outer leaf. How to install a lintel? Should lintels be caulked?

Are lintels needed for venting thru brick wall? What is a masonry lintel? In order to determine the overall length of a steel lintel , the required bearing area must be determined. The stress in the masonry supporting each end of the lintel should not exceed the allowable unit stress for the type of masonry used. The brickwork, mortar and lintel work together to form a composite beam with exceptional strength and load-carrying capacity.

Steel Lintels should be installed with a minimum end bearing of 150mm, bedded on mortar and levelled along its length and across its width. When the lintel’s bearing length is “short”, the lintel is a good approximation of a simply supported beam. The steel angles (known as shelf angles), can provide all the support, or be attached to the primary structure such as a reinforced concrete frame, to which the load is transferred. Masonry immediately above the lintel should be allowed to cure.

Point loads should not be applied directly onto lintel flanges. Consult Keystone’s technical department if applying a point load above lintels. A steel lintel becomes useful when there is no space available to accommodate the rise of an arch. In commercial construction, eye and hook steel ties that hold brick cladding to a block inner wythe are used to allow for differential movement. Save money by reducing construction costs!

When brick lintels are required to be used over large spans, they are reinforced with steel bars. These lintels are constructed on the same principles as RCC lintels, the only difference being good quality bricks are used instead of concrete. Vestal angle iron is designed for supporting masonry over windows and door. This angle is precut to the sizes most commonly used in residential housing. Filter Clear all Shop by Type.

Angle Section Lintels (1) Internal Lintel (1). Class B Red Engineering Brick 65mm. Steel lintels require no shoring, but can interfere with jamb steel in reinforced masonry construction where the lintel bears on each side of the opening. Steel lintels must be fire-proofed and have Building Code Requirements and Specification for Masonry Structures reported by the Masonry Standards Joint Committee (MSJC). We stock brick lintels made from hot dip galvanized or primed steel in sizes in gauge steel up to 48” and gauge steel up to 96”.

These are roll formed with two ribs for added strength and brick stability. We are also able to provide you with a wide range of eave lintels in either galvanized steel or primed after fabrication. With the intended position of the lintel marked on the wall, carefully use an angle grinder or masonry saw to cut away the mortar. An angle iron lintel is a piece of steel lintel that is bent at a right angle to provide support.

Adequate bearing should be achieved at either side of the lintel – A lintel will need a certain amount of cover or bearing either side of the opening that it supports. Lintel width should equal the width of the supported masonry wythe. D CAD detail of a TYPICAL STEEL LINTEL DETAIL including annotations.
