INSTALLATION
The construction is built
on cast iron forms, which are removed after the concrete has set, leaving
no exposed iron work; by this feature we eliminate the rusting and rapid
deterioration of the old-fashioned cast iron lights. Any other construction
having exposed iron work, whether painted, galvanized, or
otherwise protected, is subject to rust, warpage and buckling, being
without resistance to temperature stresses. All construction work done
by this company insures a waterproof and permanent installation.
SLAB
The sectional view of the
slab on page two of the booklet shows the general design,
patented and exclusive features of the standard construction. The
glass and slab are one inch in depth, the concrete ribs, extending in one
direction only, from building to curb, are three and one-half inches in depth.
The concrete between the rows of glass parallel with the building is in
depth the same as the glass,-- one inch.
BUCKLING OR SAGGING
Because of the depth of the
construction and absolute position of reinforcements, the Bruner System
cannot buckle or sag.
