Technical purpose The voestalpine Metsec metal channel framing system comprises of single and combination channels and assembly brackets, . The integration of these items in their use, forms the basis of the system and as such should be purchased as a complete system.
This EPD is based on ZM coated Steel supplied by Arcelor Mittal and the products are manufactured from steel supplied in accordance with EN 10346:2015 of the standard. The coating Magnelis® ZM310 is a corrosion protective alloyed coating composed of zinc, aluminium and magnesium.
Comprehensive load tables are available for each channel type. The basis of design and formulation of these load tables:
1. Safe loads calculated in accordance with BS EN 1993-1-3 Code of Practice for Design of Cold Formed Sections (2006).
2. Minimum Yield Stress (YS) 280N/mm²
3. Beams assumed simply supported and provided with adequate lateral restraint over the given span.
4. Beam loads are applied through the shear center of the section in the direction indicated in the tables.
5. Alternative beam safe load tables are provided for a uniformly distributed load or load concentrated near the center of the span
6. Beam loads and corresponding deflections are calculated at a stress of 175N/mm2 i.e.: using a global factor of safety of 1.6 to determine safe working loads from limit state analysis (ultimate stress ÷ 1.6 = 175N/mm2). Beam safe loads tabulated with corresponding deflections may be used in the rare case where excessive deflection does not impair the strength or efficiency of the structure or its components or cause damage to the supported work. Alternative safe loads are tabulated with deflections limited to span/200 or span/360 at the discretion of the designer and recommended where deflections are critical. It is easily recognizable from the tables whether the design of the beam is governed by deflection or stress on a given span i.e.: the critical load is highlighted in color.
7. Column effective lengths shall be determined by the designer in accordance with Table 9 of BS EN 1993-1-3.
8. Beam loads are generally applied at the column face via the connection bracket. Therefore column safe load tables are provided allowing for this eccentricity of load from the centroid of the section.
9. Load tables are supported and verified via extensive independent testing |
