Aluzinc doors are highly recommended as the doors are light weight, very strong, do not fade and require almost no maintenance or up keep – if the door is dirty you can simply hose it down with water.
Aluzinc is mild steel, coated in an aluzinc mixture, 45% aluminium 55% zinc, the paint is then baked onto the steel, creating two layers of protection for the mild steel.
Aluzinc Garage Doors are available in the following styles:

Aluzinc Sectional Overhead Garage Doors
Sectional Door – Sizes
LHV Garage Doors & Gates has two different suppliers for aluzinc doors, both of whom are the top suppliers and manufacturers in this industry in the Western Cape. Each supplier uses the same aluzinc material but the wood grain finish as well as the style of the raised and fielded panels used for the doors, differs between each supplier.
Supplier A uses double sided gaskets and has anti finger pinch panels.
Standard sizes of garage door openings for aluzinc sectional overhead doors:
| Door Type | Supplier | Measurements |
|---|---|---|
| Single aluzinc sectional door | Supplier A | 2440mm (w) x 2150mm (h) |
| Single aluzinc sectional door | Supplier B | 2440mm (w) x 2200mm (h) |
| Double aluzinc sectional door | Supplier A | 4900mm (w) x 2150mm (h) |
| Double aluzinc sectional door | Supplier B | 4900mm (w) x 2200mm (h) |
It is important to note that these are the standard opening sizes for your garage door opening, as a maximum of 100mm still will be added to these sizes to get the standard panel size of the garage door itself. All sectional overhead doors need to overlap, on each side with a minimum of 30mm to a maximum of 50mm, on the inside side walls of the garage. The door should also overlap with 30mm at the top of the garage.
Sectional Door – Colour Options
All aluzinc doors have a wood grain finish and come in 4 standard colours;
- White
- Charcoal
- Brown
- Bronze
Other colours are available at an extra charge, either powder coated or spray painted onto the door.
Sectional Door – Design Options
The aluzinc sectional overhead doors are available in either a horizontal slatted or raised and fielded (block) panels. It is however, important to note that if you opt for raised and fielded panels, and your door is not a standard size, you should consult your installer as to whether the blocks will be cut off, either on the sides or at the top of door, in which case, you should probably have a horizontal slatted door installed.
Windows can be installed into the aluzinc garage doors:
- Square aluminium framed glass windows or;
- Elongated horizontal oval rubber framed glass windows (black rubber) or;
Sectional Door – Requirements / Specifications
Sectional overhead doors should be installed if your garage is on the boundary or if there is limited space in your driveway in front of the garage, this is because sectional overhead doors slide directly up and over into the ceiling of the garage, in five sections, leaving the full opening of the garage available, as opposed to tipping up and out of your garage, as in the case of a tip up door.
Sectional overhead garage doors require 450mm head room, from the bottom of the lintel to the bottom of the ceiling or rafters, for installation, this amount of head room must follow through 3m back into the garage. It is possible to install a sectional door with a minimum of 250mm head room, however this will require a flip over panel to be installed.
Flip over panel simply means, that when the door is in the closed position, the top panel will still be in a slanted open position, which the motor will then push closed onto the lintel. Therefore, if a flip over panel is installed, a motor is essential to the door closing fully, and in this case, it is recommended that a battery back-up be installed onto the motor.
For a sectional overhead door to be installed properly the garage needs to have a minimum of 150mm wall nip space on either side of the garage, ideally 200mm nip space is needed.
Single sectional overhead garage doors either get installed with tension or torsion spring mechanisms, but more often than not, single sectionals are installed with tension springs. Double sectional doors should always use a torsion spring mechanism.
- Tension spring mechanisms have a spring on either side of each track.
- Torsion spring mechanisms have either one or two springs, depending on the weight of the garage door, mounted onto a torsion pole above the door.
Both these mechanisms neutralise the weight of the garage door, making it easy to manually move the door up and down.
Aluzinc sectional overhead garage doors have a rubber seal inserted onto the bottom of the garage door, which allows the door to get a complete seal on the bottom floor, preventing far more dust etc, from entering the garage.
Side seals are also available to be installed on the outside of your garage door, on either side. These are used to completely seal the door from the outside elements, as the rubber seals are placed right up against the door. A sectional garage door should sit 10mm away from the garage walls, in order to prevent the door scratching on the walls or getting caught on the wall, preventing the door from sliding smoothing up and down.
Sectional Door – Maintenance
- All sectional overhead garage doors need to have the tracks, cables and springs regularly sprayed with silicone spray or Q20.
- Greasing the doors’ hardware is not recommended as the grease forms a grinding paste with dust and sand particles, which encourages rust and decay.
Aluzinc Tip Up Garage Doors
Tip Up Door – Sizes
LHV Garage Doors & Gates has two different suppliers for aluzinc doors, both of whom are the top suppliers and manufacturers in this industry in the Western Cape. Each supplier uses the same aluzinc material but the wood grain finish as well as the style of the raised and fielded panels used for the doors, differs between each supplier.

Tip Up Door – Design Options
The aluzinctip up doors are available in either a horizontal slatted or raised and fielded (block) panels. It is however, important to note that if you opt for raised and fielded panels, and your door is not a standard size, you should consult your installer as to whether the blocks will be cut off, either on the sides or at the top of door, in which case, you should probably have a horizontal slatted door installed.
Aluzinc tip up doors have an exposed visible galvanised steel strip on the edges of the tip up garage door.
Tip Up Door – Requirements / Specifications
Tip up doors should be installed only if your garage is not on the boundary or if there is enough space in your driveway in front of the garage, this is because a tip up door tips up and out of your garage, which means that a car or anything for that matter, cannot be parked directly in front of the garage door.
Tip up garage doors need 200mm head room, from the bottom of the lintel to the bottom of the ceiling or rafters in the garage, for installation. When the aluzinc tip up door is in the open position the garage will lose +/- 100mm from its height.
Single tip up garage doors are installed with a hinge and tension spring mechanism on either side of the garage door. Each hinge contains a needle pin bearing. Double tip up doors should always have two springs attached to each hinge, in order to neutralise the weight of the double door. Both these mechanisms neutralise the weight of the garage door, making it easy to manually move the door up and down.
For a tip up garage door to be installed properly, the garage needs to have 80mm wall nip space on either side, this is where the styles of the tip up door are installed. If this is not available, the style will become more visible.
Tip up garage doors require two styles for installation. A style is a tall cubed piece of timber, usually 69mm x 45mm wide, for single doors, 69mm x 69mm wide for double doors, spanning higher than the garage door opening height. Each style is installed on either side of the garage opening, on the inside of the wall.
The hinges and springs are then mounted onto the styles and the door attached to the hardware. The door should be +/- 30mm smaller than the opening size of the garage, to ensure that the door will clear the opening, when tipping up and open.
The styles also ensure that the door does not rub up against the garage walls, but rather can rub up against the wood of the styles, preventing any scratching and damage to the door.
A tip up garage door must have a minimum of 20mm overlap on the inside of the garage, at the top.
