Purlin Roll Forming Machine: The Development In Building Industry

1
Purlin Roll Forming Machine The Development In
Building Industry
2
Buildings of the future will be constructed
principally of concrete and metal. Steel is a
particularly valuable material for both framing
and cladding walls and roofs. Houses made of
steel are quick to erect and easy to insulate,
are both cost effective and lend themselves to a
variety of designs, and are the most
earthquake-resistant. 
3
Sheet metal is transformed by the roll form
process into studs and purlins for framing, into
panels for cladding and roofing, and into
insulation. Roll forming is a technique for
taking coils of sheet metal and bending the
material into a variety of profiles. 
4
 Purlin roll forming machine requires little
labor, can be integrated into a system of
automatic processes such as bending, perforating,
and joining, and lends itself to round the clock
operation. Roll forming products for the
pre-engineered building presents significant
challenges for manufacturers.
5
The metal building industry has changed
dramatically in the past few years. Builders
demand better quality materials, faster lead
times, and more economical prices.
6
Prepainted materials have largely replaced
postpainting framing, and galvanized metal is
being employed more frequently, particularly in
areas near the ocean and in agricultural
applications. High strength steel is being used
increasingly, profile and punching specifications
are becoming more exacting, and product types are
becoming increasingly complex.
7
Roll form system manufacturers have responded
with machines which are easier and more flexible
to operate, can manufacture a wide range of
products, are faster and more productive, as well
as more economical.
8
For example, coil handling equipment now enables
the manufacturer to quickly switch coils to a
different gauge or material. This is a response
to the fact that jobs now require producing a
complete building rather than rolling long runs
of the same component.
9
The modern roll form machine is designed to
quickly switch profiles from cee to zee, from
single to double slope eave struts, to different
flange and web sizes, and to different material
gauges, in order to fulfill one particular
customer's order.
