Structural · Lintels & Headers

Structural Lintel and Header Engineering

A lintel or header carries the load from the structure above a wall opening — its design depends on the span, the load above, the wall type, and the bearing support on each side. Under-designed lintels crack, deflect, and eventually fail.

How Apex Grid Handles This

Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. We engineer structural engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package.

We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents, permit drawings, and calculations that building departments accept the first time.
