SBN prestressed concrete lintels

They are available in two sizes: 72 mm high and 115 mm wide, and 120 mm high and 115 mm wide. They are lighter than traditional L-shaped lintels. Their span reaches up to 4.2 m, which eliminates the need for casting long beams ‘in situ’. They are easy to install and highly functional; they can be used in door openings in partition walls, in garage doors and many other places – without the need for additional work.

Investors may find it important that roller shutter cassettes can be installed without reducing the glazed area. It is also worth mentioning the remarkable span of KONBET SBN prestressed concrete lintels, which reaches up to 4.2 m, whilst the longest L-19 lintels have a span of only 3.6 m. This feature is particularly important when installing items such as garage doors.
