Ceco Bar Joist Information

Does anyone have any information on a Ceco Corp. bar joist? The tag designates the bar joist as a 24H8 40-5 AJ2 joist. Its a long shot but figured it would be worth asking.

Based on the designator (24H8) and the name, it is a proprietary manufacturer that is long out of business. I have run into this type of problem before on remodels. The best advice I can offer is to look up the designation 24H8 in the historical manual put out by the Steel Joist Institute to determine what the original design load capacities were. Each manufacturer (and there were several) was permitted to utilize their own proprietary designs / material sizes as long as they met the standard load capacity tables. If you are in a pinch and don't have the historical manual, sometimes the SJI will assist in providing that information, it really depends on who assists in answering your question.

If you need to look at an updated, specific loading for the joist, you will need to take detailed measurements of the entire joist and build a model using the appropriate steel capacities under the original and revised loading scenario. IIRC, all the steel needs to be set to 36ksi strengths.

That makes sense and thank you for the information.

We are filling out the SJI joist determination request form so hopefully that will yield some dividends as well.
