The document summarizes Henrob's cold formed steel assembly solutions using self-pierce riveting. Henrob's self-pierce riveting process joins steel members automatically in one second without predrilling, providing a strong, consistent joint that does not damage coatings. Their riveting tools and rivets are designed to efficiently assemble a variety of cold formed steel components for wall panels, roof trusses, and floor trusses.

1. HENROB ASSEMBLY SOLUTIONS
Cold Formed Steel Construction
The conventional method of assembling cold formed steel (CFS) is with screws or
welding. These methods are labor intensive, time consuming, provide inconsistent
joint strengths, and can damage the material coating.
The HENROB Assembly Solution
With Henrob Self-Pierce Riveting (HSPR) in approximately one second CFS
members are assembled with an automatic feed, closed-loop insertion tool
providing a repeatable assembly method that is efficient, strong, and non-damaging
to the material coating.
HSPR is a process of joining two or more materials using an engineered rivet.
Unlike conventional riveting, HSPR does not use a pre-drilled or punched hole!
The rivet is driven into the material stack at a controlled force - piercing the top
layer(s) and flaring into the bottom layer - to form a strong, secure joint.
Other advantages of HSPR:
Rivets are supplied in a plastic belt and
packaged on spools or in cassettes assuring
the efficient use of rivets, accurate batch
traceability, and the elimination of manual
handling of loose fasteners.
Riveting tools are powered and controlled by a
stand alone, automatic, closed loop hydraulic
system - assuring accurate insertion force
from rivet to rivet and simple single push
button cycle actuation.

RIVETS
All Henrob rivets are designed and manufactured at Henrob facilities and conform to
QS9001 and ISO/TS16949 quality standards. For cold formed steel assembly
Henrob recommends an zinc/tin finish (H05) however, other finishes are available.
