American Iron and Steel Institute Research Report

I learned today a new research report was recently published by American Iron and Steel Institute (AISI). This report (RP15-2 published in April 2015) pertains to the design of load bearing clip angles. Keymark is currently in the process of developing a set of standardized truss details which will include steel truss to truss connection. The timing of this American Iron and Steel Institute (AISI) research report is fortuitous, as our engineering staff will be able to use the findings in the report as a guide for engineering analysis of the details. Hopefully this will help our team accelerate the development of a standardized detail library, which will enable our design staff turn jobs more quickly and with similar or same connection details every time. It’ll be one more step in establishing the KeyTruss system as a world-class competitive truss system. Stay tuned!

This steel technology is exciting…

I arrived for my first day at Keymark a few weeks ago. I’ve been part of this company in the past and I felt excited to rejoin the team, which for the past 2+ years has been exclusively focused on the cold-formed steel industry.

Today I found myself in a room with two bundled packages of pre-cut, ink-jet marked tracks and studs. The first bundle was for a sample truss using the KeyTruss system. The second was a bundle for a sample wall. The task was straightforward: with only the 1-page schematic on an 8.5×11 sheet of paper as a reference, try to assemble the truss and wall components without a jig, tape measure, or anything to mark with. Here is what the schematics looked like:

Like a tinker-toy set, matching numbers and letters worked perfectly and I built these structural components in just a few minutes! Granted, these are simple components, intended to demonstrate the concepts involved, so I can’t give myself too much credit. But the experience was very satisfying – all the pieces came together perfectly, and there was a sense of building something. This steel technology is exciting because on the surface it seems so straightforward and simple – as it should be – but underneath there is a mountain of tricky software logic to get the pieces drawn and labelled properly, to interface with the machinery that manufactures the parts, to perform the structural engineering calculations that ensure the truss or wall performs to locals building codes, and so forth.

Even more exciting is despite the ease with which these simple components came together, the Keymark team has many fantastic new ideas to make the technology even more streamlined and robust. I look forward to bringing those concepts to fruition in the weeks and months ahead. This has been a terrific experience and I find myself even more excited about the opportunities Keymark has to offer to the marketplace.

KeyTruss – Steel Truss Design

Keymark Enterprises is pleased to announce the commercial availability of its proprietary steel truss solution called KeyTruss; the latest innovation in steel framing. KeyTruss is a new and unique steel-truss system that combines the benefits of standard C-shaped steel trusses with a series of new capabilities that greatly improve performance in truss manufacturing, assembly, logistics, and installation.

The KeyTruss system leverages Keymark’s end-to-end solutions for steel framing. Keymark’s truss design software, GS Truss, automatically engineers trusses and optimizes the outputs for manufacturing. The output files are then loaded into Keymark’s GSS-2 roll former, the most advanced of our roll former product line. The webs and chords are punched, marked, rolled, and sheared exactly to design specifications.

KeyTruss saves money on truss assembly, shipping, and installation:

  • The labeling on roll-formed pieces includes all required information, along with a unique identifier system that greatly reduces the need for shop drawings. (If you can line up “web joint A” with “chord joint A”, you can assemble these trusses!)
  • Pilot holes at each joint ensure proper placement and virtually eliminate the need for alignment jigs. (Watch this video to see how easily KeyTruss pieces are joined together.)
  • KeyTruss’s in-plane construction reduces shipping volumes and costs, since each truss is a single layer that lines up nicely.
  • KeyTruss’s robust design reduces the need for web bracing, making installation faster, easier, and cheaper.

KeyTruss is available to be shipped directly from our factory in DFW area, or we can ship product neatly bundled so the assembly can be completed at or near the job site. Either way, the KeyTruss system is the steel-frame-truss solution for you!

Contact us today to find out more about this exciting new steel truss solution.
