Metal Fascia & Gutter Systems
JH Stephenson OG Gutter
JH Stephenson OG Gutter is the traditional gutter that still gives your home that Colonial look. JH Stephenson OG Gutter can now be supplied with or without overflow slots so that your home can be protected from water overflow, and by using concealed brackets, your gutter has a smooth unobstructed appearance. Made from zinc/aluminium coated high tensile steel, JH Stephenson OG Gutter is strong and long lasting.
ADVANTAGES
COST SAVINGS
JH Stephenson OG Gutter is continuously roll formed from light gauge coil steel and therefore has low initial cost. Labour savings in erection time are also made because of the quick and easy method of attaching to the Fascia. Because of the protective coating there is very little cost involved in maintaining JH Stephenson OG Gutter as it lasts years without being touched.
PROTECTION
Zincalume® and Pre-painted Zincalume® coated steel provides the best protection from the environment and gives long life to any building.
LENGTHS
JH Stephenson OG Gutter can be cut in the factory to any length specified by the customer. Using longer lengths eliminates joints and gives a neat appearance.
SUPPORT RECOMMENDATIONS
Gutter Brackets are to be placed at Stop Ends and between Stop Ends at intervals of not more than 1200mm. Where Metal Fascia is used, brackets must be placed within 150mm either side of the rafter brackets.
COMPATABILITY
Lead flashings and copper or copper alloy materials should not be used with or in run-off situations with Zincalume® sheeting. Also do not use lead head nails.
SEALING
Zincalume® or pre-painted material cannot be soldered. To seal a suitable sealant and mechanical fasteners must be used.
THICKNESS
Manufactured from:
- 0.42 G 550 BMT
- 0.55 G 300 BMT
FINISH
JH Stephenson OG Gutter is available in the following finishes:
a. Standard Zincalume®
b. Pre-prime coated Zincalume® suitable for painting.

(Colour chart available from your JH Stephenson Centres.)
INSTALLATION
FIXING TO TIMBER FASCIA
Fix a Bracket at the high end of fall first, then fix a bracket at the low end of the fall. Stringline a common datum on both Brackets and install the remaining Brackets at the required spacings (not exceeding 1200mm) with common datum on the stringline.
The Brackets are best attached to the fascia with 2 - 40 x 03.75mm Helical thread galvanised nails placed diagonally opposite.
ATTACHING GUTTER TO BRACKETS
Hook the front of the gutter onto end of the long arm of the brackets and slide back of gutter under the long arm until it is hard up to the back of the bracket. Push gutter into the upright position lifting the bottom of the gutter onto the platform provided by the bracket. When the gutter is in the correct position turn down both tabs of the gutter brackets onto the back of the gutter to complete the attachment.
SPRING CLIP SYSTEM
Fixing to metal fascia is simplistic by using the JH Stephenson spring clip which snaps over the metal fascia and has six teeth at alternative heights where the back of the gutter bead snaps into. Fall of gutter to downpipe outlet is determined by the height of the gutter attached to these teeth. The face of gutter is then supported by the JH Stephenson overstraps which connects in front bead of gutter and top bead of fascia.
END STOPS
Preformed End stops provide a neat finish to straight runs of gutter. These Stop Ends require less labour and skill than site formed ends. Both methods of end stopping require the use of monel Blind Rivets and a roofing type silicon sealant.
EXTERNAL CORNERS
Cut as shown in illustration, fold, rivet and seal.
INTERNAL CORNERS
Cut as shown in illustration, fold, rivet and seal.
GUTTER JOINING
Reduce the top rib for 25mm to allow for a slip joint. Slide the reduced end
into the other end applying a suitable sealant, Blind Rivet together using 04 Monel Rivets.
