Structural steel lintels
Angle, channel, plate and built-up lintel arrangements, with member callouts, bearing plates and connection details where specified.
Structural engineering & drafting
Lintel Design & Detailing Services
Structural design and drawing support for load-bearing openings in masonry, reinforced concrete and steel-framed construction. Coordinate lintel spans, load assumptions, end bearings and construction details with project requirements.
Scope of services
Lintels detailed for the opening, load path and surrounding structure
A lintel transfers loads above a door, window or other wall opening to its supports. Our drawing and engineering-support scope is organized around the opening geometry, supported construction, approved material specifications, end-bearing conditions and interfacing details. The appropriate member size, reinforcement and bearing requirements must be established through project-specific design and review.
Reinforced concrete lintels
Section dimensions, reinforcement schedules, covers, stirrups and integration with adjoining concrete or masonry.
Masonry wall openings
Lintel locations, supported masonry, bearing lengths, course coordination and opening-specific notation.
Special opening geometries
Corner, bay-window and architectural openings requiring tailored geometric coordination and engineer-approved load transfer.
Connection and support details
End reactions, bearing interfaces, anchorage and adjacent beams or columns as provided by the structural engineer.
Shop and construction drawings
Plans, sections, elevations, lintel schedules and revision-managed documentation for review and construction coordination.
Engineering coordination
Design considerations that affect lintel details
Lintel design depends on more than opening width. The load path, masonry or frame support and project-specific design criteria all influence the detail.
- Clear span, opening width and actual bearing or support lengths
- Dead and imposed loads, supported wall height and any concentrated loads
- Material grade, member configuration and corrosion or exposure requirements
- Bending, shear, deflection and local bearing considerations
- Reinforcement, anchorage, restraint and construction sequencing where applicable
- Coordination with architectural dimensions and nearby services
Expected outputs
Deliverables for review and construction
Lintel plans and schedules
Member marks, locations, opening references, section identifiers and design references.
Sections and elevations
Key dimensions, bearing interfaces, levels and architectural opening coordination.
Fabrication and reinforcement detail
Steel connection callouts or concrete reinforcement detail according to the approved design.
Revision tracking
Updated sheets and coordinated annotations responding to approved markups.
CAD and PDF packages
Editable drawings and issued document packages in formats agreed at project kickoff.
Review and query register
Clarification items for gaps in geometry, loads, specifications and interfaces.
Project initiation
Information required to start
- Architectural plans, elevations and opening schedules
- Structural drawings, loading data and design criteria
- Wall construction, member specifications and material grades
- Opening dimensions, support locations and bearing conditions
- Relevant detail standards, drawing templates and code requirements
- Target formats, review milestones and change-control expectations
Working approach
Coordinated delivery, not assumptions
We review the supplied scope, clarify missing inputs, develop the drawing or analytical support package, check interfaces and manage review comments. Material changes or unresolved design decisions are referred to the responsible project team before being incorporated into issued documentation.

Frequently asked questions
Lintel design and detailing FAQs
Do you prepare lintel shop drawings?
Yes, drawing packages can cover steel member dimensions, supports, connection notes and schedules based on the approved design and supplied project information.
Can you detail reinforced concrete lintels?
Yes. Section geometry and reinforcement detailing can be prepared using engineer-issued dimensions, material properties and bar requirements.
What affects lintel bearing length?
The reactions, support material and project design criteria govern bearing requirements. These must be verified by the responsible design engineer rather than set by a generic rule.
Can you update drawings after review?
Yes. Revised details and schedules can be coordinated with approved review comments and tracked by revision as part of the agreed scope.
