Abstract

A purlin with a pre-formed coating film. The film may be pre-bonded to the purlin and this may be done before the purlin is profiled. The film may be of a plastic material and may be adhesively bonded to the purlin. The bonding may also be activated by pressure and/or heat. Also described is the method of manufacturing the purlin, providing a film, a metal sheet, applying the film to the metal sheet on-line and then profiling the film coated purlin. The metal may be provided in the form of a reel which is unwound before applying the film, which may be fixed by bonding and may use an adhesive or glue. The bonding process may involve the use of heat and/or pressure. The film may also be provided in the form of a reel. The sheet and or film may be treated before applying the film.

"A purlin"
Introduction
5 This invention relates to purlins
Purlins arc generally formed by roll forming a sheet of metal such as steel to a desired profile or shape. There are two conventional ways in which to provide a purlin with a decorative coating.
10
In one method after the sheet metal is manufactured it is passed through a painting process which applies a coating to the sheet which is then rolled up onto a supply reel. A manufacturer unrolls the coated steel from the supply reel and then forms the sheet metal into a desired shape. One of the problems with this method is that such 15 reels of coated steel are expensive. Another problem is that a single reel of such painted sheet metal is very long to cater for production runs If only a short run is required with a particular finish only part of the reel is used, leading to problems in downtime in changing reels and storage of partially used reels and consequent risk of damage/wastage as well as inventory and control costs.
20
In a second method a raw metal sheet is formed to a desired purlin shape/profile by a manufacturer and the purlins are painted on site. This is also expensive and difficult because the profiles are often complex and therefore difficult to pamt. In addition, the purlins are often difficult and/or dangerous to access when erected.
25
This invention is directed to addressing at least some of these problems.

5
In one case the purlin is profiled and the film is applied to the sheet in advance of profiling.
The film may be of a plastics material.

Preferably the film is bonded to the purlin. The film may be adhesively bonded to purlin. Alternatively or additionally the bonding between the film and purlin is activated by pressure and/or heat
15 In one case the purlin has at least one exposed face and the film is applied to the exposed face
The invention also provides a method for manufacturing a purlin of the invention comprising the steps of:-

providing a metal sheet;
25 applying the film to the metal sheet on line; and subsequently profiling the film coated sheet to form a purlin.
In one embodiment the metal sheet is provided on a reel and the method comprises 30 drawing the metal sheet from the reel and applying the film to the unreeled sheet.
3
The method may comprise bonding the film to the sheet. The film may be adhesively bonded to the sheet. Alternatively or additionally, the film is bonded to the sheet by heat and/or pressure.
5 The film may be provided on a film reel and the method comprises drawing the film from the reel so that the film and sheet are in alignment for applying the film to the sheet.
In one case the sheet to which film is applied is profiled by roll forming.
10
In one embodiment the method comprises treating the sheet and/or film in advance of applying the film to the sheet.
15 Brief Description of the Drawings

Figs. 6 and 7 are views similar to Figs. 1 and 2 of another purlin according to the invention.
5 Detailed Description
In the invention, a purlin of metal has a pre-formed coating film 20 applied thereto on-line. The purlin is formed by profiling, for example by roll forming, a sheet 25 of metal to a desired shape The coating film 20 is applied to the sheet 25 on-line in 10 advance of on-line roll forming Referring to Figs 4 and 5, in this case the metal sheet 25 is provided on a supply reel 26 and the coating film is also on supply reels 27. The reels 26, 27 are set up as illustrated so that the film 20 is aligned with the sheet 25 In this case the film 20 is applied to both faces of the metal sheet 25 but it may, if desired only be applied to one of the metal sheet faces. The film may be 15 applied across the full width or only part of the width of the metal sheet.
To bond the film 20 to the sheet 25 the film 20 may be passed under a pressure/nipping roller 28. The bonding may be activated for example, by passing under pressure and/or heating plate(s) 29. Further nipping rollers 30 may be provided 20 downstream of the plate(s) 29. Edge trim knives 30 may also be provided. The metal sheet 25 with coating film 20 applied to both faces is shown in Fig. 3.
The coating film is preferably of a weather resistant plastics material such as polyethylene terephthalate (PET), ethylene tetrafluorethylene (ETFE) (which has a 25 high corrosion resistance), PVC (polyvinylchlonde) or polyolefin (PO), or mixtures thereof. The film may be adhesively bonded to the metal sheet using a compatible adhesive such as a polyurethane based adhesive. The bonding of the film to the metal sheet may be activated and/or cured by heat, pressure, UV, ultrasonics, or any combination thereof. The coating film may be provided on the exposed face of one 30 or both sheets of the panel. In the case where both sheets have coating films, the same film or different films may be applied to the sheets.
5
The film may be provided with any desired decorative finish or indicia such as to mimic wood gram, brick, or a slate-like finish.
5 The coated metal sheet is then profiled into a desired purlin shape, for example by roll forming The profiling may result in any desired shape/profile One example of a purlin 1 according to the invention is illustrated in Figs. 1 and 2.
The purlin 1 in this case comprises a first flange 2, a second flange 3, and a web 4 10 extending between the first flange 2 and the second flange 3. The first flange 2 and the second flange 3 extend from the web 4 in the same direction l"he purlin 1 also comprises a first lip 8, a second lip 9, a first lip return 10 and a second lip return 11. The first lip 8 extends from the first flange 2 and the second lip 9 extends from the second flange 3. The first lip return 10 extends from the first lip 8 and the second lip 15 return 11 extends from the second lip 9.
The web in this case 4 has a non-straight, indented section 21 between the first flange 2 and the second flange 3. In this case the purlin 1 has a "sigma" shape.
20 The purlin 1 may be manufactured from any suitable metal 1, for example steel. The flanges 2, 3, the web 4, the lips 8, 9 and the lip returns 10, 11 are integrally formed by profiling, typically by roll forming the film - coated metal sheet.
Thus, the invention provides a purlin with a film coating which can present any 25 desired decorative finish, when installed.
In Figs. 6 and 7 there is illustrated another purlin 30 according to the invention, which is similar to the purlin 1 of Figs. 1 to 3, and similar elements in Figs 6 and 7 are assigned the same reference numerals. In this case the web 4 extends from the 30 first flange 2 to the second flange 3 in a straight section 31. The purlin 30 is provided in the form of a channel.
6
The invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail.
