1. All loads are calculated in accordance with BS5950:Part 5: 1998 Code of Practice, for the design of cold formed sections.
2. The minimum yield stress of pre-galvanised steel used in the manufacturer of Hi-STRUT channels is Ys = 250 N/mm2.
3. Beam loads and corresponding deflections are calculated using a yield of 250 N/mm2. These values are calculated in accordance with section 3.4 of BS5950:Part 5.
4. All beam loads and deflections stated do not apply to material that has been post galvanised i.e. (heat treatment has been applied after forming). If beam loads and deflections are required for post galvanised products please contact, the manufacturer.
5. A global safety factor of 1.6 was used to determine safe working loads from limited state analysis.

6. Column loads are calculated in accordance with section six BS5950:Part 5. Effective column lengths to be determined by the designer in accordance with Table 9 BS5950:Part 5.
7. Column loads have been calculated so that the maximum slenderness ratio Le/r does not exceed 180°.
8. Beams are assumed to be simply supported and provide adequate lateral restraint over the given span.
9. Beam loads are applied through the shear of the section in the direction indicated in the tables.
10. Alternative beam safe load tables are provided for a uniformly distributed load or concentrated near the centre of the span. (See Figure 1.).
11. Example of how to evaluate the ultimate load on an intermediate span. Extract from the S100 Load Table not shown in tables.
