Steel Lintel Load Table
You may have seen some specification tables on our product pages for our steel lintels. But, you aren’t too sure what all the parts really mean? Well, you’re in the right place! Let us tell you!
Below is a detailed diagram of what all the parts of our specification tables mean.
Concrete Load Span Tables
The concrete lintel specification tables are similar to steel lintels, however, there are two slight differences.
- So, the first difference is the UDL which stands for ‘Uniformly Disturbed Load’, this is measured in kilonewtons per metre, this will be shown on the table as kN/m. They are simply the opposites of what the steel load tables are, steel load bearing capabilities go up as the length increases. Whereas, with prestressed concrete it is quite the opposite, the longer the length the lower the load bearing capabilities.
- Clear span is the length of the opening. So, if for example you have a clear span of 1500mm, you will need a 1800mm this is to fit the required span of 150mm each end of the opening.
- Good thing you may want to know, our concrete fire rating is 30 minutes.
Very important thing to remember is not to confuse the kNm with kN/m. They are very similar, and it is so easy to confuse the two. However, the kN/m is kilonewtons per metre or divided by metre. Whereas, kNm is a force measurement where kilonewtons are times metres.
