Steel angle lintels are used frequently to support veneer systems (especially masonry). Currently the only code that supports steel angle lintels is under the Australian section.
Similar calculations for both US and Canadian codes would be a great benifit if possible.

Your idea is valuable to us, and we’ve added it to our list of potential enhancements. While we do our best to prioritize user-driven improvements, we also have other projects we’re balancing, so it may take a bit of time to see this feature in action.
