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 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.
All tip up garage doors, however, do have springs and hinges that should be regularly sprayed with silicone spray or Q20 in order to help maintain a longer lifespan of the tip up door hardware, as well as preventing rust erosion and sticking hinges. Greasing the doors' hardware is not recommended as the grease forms a grinding paste with dust and sand particles, which encourages rust and decay.

LHV Garage doors & gates have 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, however, does not provide a rubber seal at the bottom of the door, whereas, supplier B does manufacture its doors with a rubber seal riveted onto the bottom of the tip up garage door panel. LHV uses both suppliers, as the one supplier can offer a wider sized door at a standard price, while the other supplier offers a higher sized door at a standard price, which allows LHV to provide a better service to our clients.

Standard sizes of garage door openings for aluzinc tip up doors:

  • Single aluzinc tip up door (supplier A): 2700mm (w) x 2150mm (h)
  • Single aluzinc tip up door (supplier B): 2500mm (w) x 2200mm (h)
  • Double aluzinc tip up door (supplier A): 4800mm (w) x 2150mm (h)
  • Double aluzinc tip up door (supplier B): 4900mm (w) x 2200mm (h)

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. The aluzinc tip 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 STD 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 a visible galvanised steel strip on the edges of the tip up garage door.

Windows can be installed into the aluzinc garage doors:

  • Square aluminium framed pvc windows or;
  • Elongated horizontal oval rubber framed windows ( black rubber)

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 of the garage, 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.
