Precision in bolted connections is not a luxury; it is the foundation of load-bearing capacity in steel framing. When the machine creates the slot and pilot hole, it is ensuring that the load transfer between the structural bolt and the ZAR 250 profile occurs exactly where the calculations predicted.
Using a needle-point bolt in a pre-drilled hole is not an assembly whim; it is essential for the metal deformation and helix to generate the friction that prevents slippage. If this is replaced with a standard self-drilling screw, the geometry of the connection is destroyed. Visit our website www.prosteel.com.ar to understand why tolerance in these details determines whether a structure withstands or collapses in a gust of wind. The bolt is for single use only. Removing it renders the hole unusable because the steel has already yielded locally. That is not rigidity; it is a failed connection that is then repaired with a construction rivet.
Precision #steelframing technology doesn't allow for these corrections because the profile's core no longer functions the same way.

The most serious conceptual error is believing that a PGC flat bar performs the same as a UPN. The C-section improves in-plane strength, and the purlin is not simply a plate support: its primary function is to reduce the buckling span of the compressed stud. Ignoring this and using it only as a fascia is a waste of steel and structural capacity.

The difference between old and new technology isn't just automation; it's respect for the steel's inherent properties. #Dryconstruction that doesn't control those points is simply assembly, not engineering.
