FENCES & GATES
Superior Balustrade fences and gates are basically constructed from pre-powder coated or anodised fence rail and tube. That tube is expanded into the fence rail by a patented process owned by the Company. The fence rail is drilled by a high speed milling machine using tungsten carbide cutters and the milling machine optimises bar spacing by computer programme prior to the bars being inserted and expanded in place.
Gates are basically an extension of the fencing system and use a lighter weight post at either end of the “panel” and this post is closed off at the top by some form of “stylised” post cap and the bottom is closed off by a post cover plate. The tubes are normally closed off by plastic plugs or can be decorated by a variety of spear tops. An alternative is to introduce another horizontal fence rail and roll curve a top rail to give the gate more style.
Lightweight gates are normally hung on self-closing plastic hinges and latched with drop latches and driveway gates similarly normally operate with similar hinging and latching because of their light weight. Here a gate is hung on gudgeons because it was desirable to open both ways.
Aluminium gates provided they have not been welded or heated in manufacture are extremely strong and often out-perform steel and wooden gates and require little or no maintenance.
Single spans of up to 5 metres are practical provided the gate-post and hinge can take the load.
Usually if you can draw the gate we can build it for you. Gate posts are usually 50 mm diameter square section – horizontal rails are 30 mm wide and 45 mm deep – vertical tubes are 21 mm diameter. We can roll-curve the horizontal rails to a 2 metre radius and that opens options to vary design.
To give you a basic indication of cost we need to know:
1. What the gate posts are made from and how the gate is to be latched and hinged.
2. The height and width of the opening and clearance below the gate – if there is a slope.
It is usual to allow a gate to clear the ground by 50 mm and keep the height below the supporting posts. Hinges and latches require a clearance of 15 mm each side. So gates are usually built to be 30 mm narrower that the distance between the supporting posts.
Aluminium castings can be incorporated into designs without altering the basic gate structure and safety glass panels can be printed with logos, street numbers or advertising material. The design is printed onto the glass and then the glass is thermally toughened and the printing becomes a part of the glass and is therefore virtually permanent. Frosting of glass gates also offers privacy and frosting of glass balustrades is now quite common.
Aquila Series fencing is a popular for swimming pool fences. The two-part post allows for panels to be transported to site as “units” and joins occur inside the post, once the foot plate is attached. The fencing is very strong and spans of up to two metres are chosen for convenience of “one person assembly”.
Higher fences are often used around school buildings and marinas where heavier posts are sometimes used.
Panels are manufactured in the Company Factory in New Plymouth, packed on a pallet and transported to the Auckland Agent. Panels interlock and are separated by foam blocks and travel securely of wooden pallets. Posts are attached on site.
Light duty fencing and gates are a popular domestic option. Attachment to brick pillars is by way of cast brackets.
Louvers and rail fences can be used for privacy in dwellings. Rails have the advantage of being easier to roll-curve.
