Precast lintels are manufactured in "U" shaped form and are
designed to support predetermined gravity load capacities, thus expediting
concrete masonry construction for both the commercial and residential
contractor. When filled with concrete grout they form a composite beam
system that has added load carrying capacities.
Suitable for residential or commercial applications, the Power Box and L-2 Steel Lintels are made of cold roll formed galvanized steel sheets.
Their many benefits include:
Easy to use
No lifting equipment needed
Only one man needed to set them in most cases
Quick and easy to install for the mason
Easy to transport
Ideal for textured covering and other finishes
Can span openings up to 38’-8” affordably
Allow elimination of many columns that impair aesthetics
