FENCING INSTALLATION GUIDE

METLINE®

2

Please Note Carefully Before You Start• This installation guide does not cover fences above

1.8m. For fences higher than 1.8m, please ring the Metroll office

• Describe your site details when ordering materials • Identify the soil type for your fence site as this will

determine the concrete required for the job• Make sure you know the whereabouts of underground

electricity, gas or water mains before you begin digging• Check with your local council regulations for boundary

fencing• Ensure you read through this guide completely before

you begin, to ensure you fully understand the installation process

• Check the delivered material for the correct number of components & general condition

IMPORTANT!• Ensure post holes are of correct size & filled with

concrete• Ensure that the recommended number of self-

drilling screws is used to join two posts together

Site DetailsFencing made from COLORBOND® steel is designed to withstand most wind conditions. The wind on the fence at your site will depend on a number of factors, including where you live and the number of surrounding properties. These details will help Metroll to tailor a design that is best for you. If in proximity to severe marine conditions or bounding swimming pools please ring Metroll for advice.

What does your property look like?

Choose the site that best resembles your area

1. Typically has numerous closely spaced obstructions, such as houses or developed trees. These areas may have roads and canals less than 200m wide and open spaces less than 250,000sqm. e.g. Typical suburban housing developments that may include parks or lakes.

2. Typically has few trees and isolated obstructions. e.g. Fronting open areas unlikely to be developed in the next two years.

Where do you live?

If you provide these details to Metroll, it can help to provide better fencing solutions for your property

Stepped or Raked FencesThe fence can either be built to step down the slope or sheets can be cut so that it follows the shape of the earth-a raked fence. The raked fence is the preferred option as it leaves no gaps under the fence, is better in appearance and is stronger.

Uneven Sites

Vertical slitting (cutting) of sheets may be required if slope is greater than 1 in 8. The preferred method of installing fencing for best results and most efficient fitment is the slitting method.

Once the fencing panels are placed, the slit can be closed up by driving back along the line of the fence.

This may reduce the three sheet coverage to a point where one of the sheets may require vertical slitting. The top rail angles can be adjusted to create a smoother angle. The post height required will increase, so allow for this when fixing the posts in the ground.

The preferred method of cutting sheets, is to use a nibbler or slot shear. If angle grinders or drop saws are to be used, extra care should be taken to ensure all swarf is cleaned off the sheeting.

STEP 2 – Securing Posts

End Posts, Corner Posts & JunctionsDimensions of the SHS section and fence posts will vary according to the fence supplies. Contact Metroll for details.

Tapering the Front of Your FenceMetroll recommends that you taper the last two panels of your fence at an unsupported end, particularly where your fence extends beyond the front of your house.

Cut sheets as per the instructions in the ‘sloping of uneven sites’ section.

The minimal extra effort in tapering the unsupported end will provide a better-looking fence than a stepped fence and is much stronger than leaving it at full height.

NOTE: A LONGER TOP RAIL WILL BE REQUIRED FOR THE TWO TAPERED PANELS

3 INFILL SHEETS

STEP 3 - Installing Infill Sheets• Insert bottom rail between posts to determine exact

locations of next post• Adjust bottom rail to correct height - it is important to

maintain a minimum gap of 50mm between bottom of rail & ground

• Screw fix the rails at this stage• Place top rail into post & fix with self-drilling screws on both

sides of posts. Ensure that the self-drilling screws are not fully tightened, as they need to be removed when inserting sheets. Ensure the position of the top rail is protruding 2mm above the top of the posts to reduce the risk of injury

• Continue this procedure until fence length is achieved• Allow the concrete to cure overnight. Note: Longer curing

period may be required in very cold and/or wet weather• Unscrew top rail & remove• Fit infill sheets into bottom rail ensuring correct lap as per

diagrams below• Place top rail on infill sheets, working from one end to the

other, locating the profile in the rail. A gentle tap with a rubber mallet may help

• Secure the top rail with self drilling screws on both sides• Hose down with good water pressure when finished to

remove any swarf such as drill filings or remnants from the nibbling process

• Check installation

Incompatible MetalsDue to galvanic corrosion, some metals such as copper and lead can cause accelerated corrosion when used with ZINCALUME® steel or COLORBOND® steel.

Copper pipes and lead flashing should not come in direct contact with either ZINCALUME® steel or COLORBOND® steel. If building design is such that water will flow from lead flashing onto ZINCALUME® steel or COLORBOND® steel then it should be painted.

Water from copper pipes should not be directed onto COLORBOND® steel or ZINCALUME® steel.

Stainless steel fixings and fixings containing copper should also not be used with ZINCALUME® steel or COLORBOND® steel.

Uncoated MaterialThe use of uncoated steel supports for ZINCALUME® steel or COLORBOND® steel is discouraged as the possibility of corrosion of the overlying sheeting may be greatly enhanced. Where heavy steel sections such as hot rolled steel angles are necessary for structural requirements, the steel sections must be post painted with an appropriate high build industrial coating system or galvanised.

Such procedures are regarded as imperative to prevent the deterioration of the steel member and consequently, the rapid degradation of the sheeting. Advice should be sought from reputable coating manufacturers in regard to the specification of an appropriate coating system which will offer suitable corrosion resistance for the particular exposure environment.

Fencing Maintenance & Warranty

• To keep your fence looking its best, wash your fence down periodically with water when washing the car or watering the garden. A soft broom should be sufficient to remove any cobwebs. Pay particular attention to the area under the top rail, which is sheltered from natural washing by rain.

• Do not build up soil, garden fill and/or dirt against the bottom rails and posts of your fence as this will retain water and lead to corrosion.

• Do not use your fence as a retaining wall, as it is not designed for this purpose.

• Avoid spraying the fence with garden sprays or fertilisers as these can damage the surface. If this occurs wash the fence down with water

• Adequate drainage is needed to ensure that water does not pond in the bottom rail and to assist in the removal of debris. This is often achieved by pre-punched holes in the bottom rail, or by designing the posts such that there is a clearance between the ends of the bottom rail and the posts.

• Do not use touch up paint. Minor scratches should be left alone or the infill sheet replaced. Touch up paint will weather differently than COLORBOND® steel.

• Fencing is backed by a 10 year manufacturer warranty under the following conditions:

• Installation > 1km from Marine or Industrial Development• Fence is installed to manufacturer’s guidelines• Fence is maintained regularly in accordance with

BLUESCOPE® steel

COLORBOND®

COLORBOND® steel has a well-earned reputation for quality and durability. That is why when buying pre-painted steel fencing from a fencing manufacturer or supplier, you should always insist the steel is COLORBOND® steel.

The technology behind COLORBOND® steel is world leading - and it was developed right here in Australia to withstand the harsh climate conditions of Australia.

1. First, a base of ZINCALUME® steel ensures outstanding anti-corrosion performance

2. Next, a conversion layer is chemically applied to enhance coating adhesion

3. Then, an epoxy primer is baked onto the surface

4. And finally, a durable, exterior grade topcoat is baked on
