SUMMARY

The discussion focuses on designing a folding bunk bed using a metal wire mesh for the top bunk attached to an aluminium square tube frame. The design must support a load of 100kg, necessitating careful consideration of the mesh's weight and structural integrity. Participants confirm that using wire mesh is feasible and suggest using fasteners such as bolts, rivets, or adhesive for attachment. Additionally, they recommend analyzing the bending stress of the materials to ensure safety and durability.

PREREQUISITES
  • Understanding of structural engineering principles, specifically bending stress analysis.
  • Familiarity with materials science, particularly the properties of aluminium and wire mesh.
  • Knowledge of fastening techniques, including the use of bolts and rivets.
  • Basic skills in design software for structural modeling (e.g., AutoCAD or SolidWorks).
NEXT STEPS
  • Research the weight specifications of various wire mesh materials suitable for load-bearing applications.
  • Learn about bending stress calculations and how to apply them to aluminium structures.
  • Explore fastening methods and their impact on structural integrity in furniture design.
  • Investigate design software tools for simulating load-bearing scenarios in structural designs.
USEFUL FOR

Furniture designers, structural engineers, DIY enthusiasts, and anyone involved in creating safe and functional furniture solutions.

Would this work...?

Im designing a folding bunk bed and was wondering whether to keep the weight down I could use a metal wire mesh material as the top bunk fixed to aluminium square tube?

Also would it be possible to attach this to the tube main frame fairly easily and how much does the mesh weigh per m squared as iv done some research but can't find this detail out? The top bunk needs to support a load of 100kg in use.

Thanks for the help guys.

How much does wire mesh weigh? Well how thick are the strands, and how many strands are there per square metre? Doesn't take a lot of effort to work that one out.

Sure you could use a wire metal mesh fixed to aluminium tube, just use some fasteners (bolts, rivets, adhesive, imagination).
 
Ok thanks. Could you offer me some advise on how i might go about analysing the bending stress of the material for a certain size?
